rapidly acquired, configured fielded and connected to supporting and 
supported databases worldwide. This is accomplished by integration and 
fielding of specialized systems in response to specific requirements. The 
hardware components/peripherals of these specialized systems (a combination 
of Government supplied and commercial hardware/software) will typically be a 
combination of UNIX, PC, communications, and peripheral components. Such a 
bundle is defined where there is not a preponderance of one component such that 
the requirement could be satisfied by a bundled UNIX or PC system. When the 
Government orders a bundled specialized system, the Contractor shall acquire, 
assemble, integrate, deliver, install and provide on-site support for the 
system in as specified in an appropriate Order for Commercial Items 
(SF 1449). During the contract period, integrated specialized systems 
requirements will be identified by the Government: in this event, the 
Contractor will propose appropriate technology updates to satisfy the 
requirement. The Government anticipates using product number (2050 and 2200, 
Specialized Bundled Systems) to order fully integrated systems consisting of 
a combination of components (UNIX, PC, communications & peripherals) not 
otherwise wholly supported by any other Requirements Area. The Government 
will provide full details of the required configurations as part of the Order 
For Commercial Items (SF

of these configurations with Government representatives prior to responding 
to the request for quote. The systems may be any combination of Government 
Furnished Equipment (GFE) hardware or software and commercial equipment which 
must be provided by the Contractor. The contractor will be expected to 
acquire (if necessary) and integrate the components and provide a fully 
operational system.

                SASS Hardware II Contract Management Plan (CMP)

                              Section I - General

1. PURPOSE. To establish policy, responsibilities and procedures for 
management, administration and use of the Systems Acquisition Support 
Services (SASS) Hardware II Information Technology (IT) contracts.

2. REFERENCE.

      a. Federal Acquisition Regulation (FAR) and Department of Defense 
Federal Acquisition Regulation Supplement (DFARS).

      b. SASS Hardware II contracts.

      c. SASS Hardware II Ordering Guide.

3. INTRODUCTION.

      a. General. The SASS Hardware II contracts provide readily available 
sources for competitive acquisition of a wide range of current and emerging 
Information Technology (IT) for the DoDIIS and other members of the 
Intelligence Community to support the following objectives:

              (1) Multiple contract sources for products which meet the DoD 
Joint Technical Architecture (JTA) and DII COE standards.

              (2) Achieve the economic advantage of competition by offering 
the SASS Contractors the opportunity to be considered for award of Delivery 
Orders by review of Product Table prices for requirements under the Small 
Acquisition Threshold (SAT) and competition, by RFO, of requirements above 
the SAT.

              (3) Sources for COTS products, which support the objectives and 
implementation of the Joint Intelligence Virtual Architecture (JIVA).

              (4) Sources for products and technological advances to enhance 
existing baseline capabilities.

      b. Use of Web Technology. Resource limitations dictate that, to the 
         maximum extent possible, contract operations and support activities 
         be conducted utilizing web technology. Accordingly, contracts and 
         related support documents are available at the following web locations:

      INTELINK: http://delphi.di.ic.gov/proj/dodiis/sass/sass.html

      INTERNET: http://www.dia.mil/vaca/sass/sassii_hw.html

monitoring and tracking orders issued, maintaining an accurate record of 
dollars expended against the contracts and assisting in resolution of 
problems.

      f. Defense Contract Management Command (DCMC). The DCMC is responsible 
for providing contract administration and close-out or termination services 
through its contract administrative offices to include:

              (1) Support to fact finding and negotiations.

              (2) Safety and environmental assurance.

              (3) Evaluation of Contractor processes and controls.

              (4) Evaluation of Contractor corrective actions.

              (5) Independent evaluation of Contractor progress.

      g. Defense Finance and Accounting Service (DFAS). The DFAS is 
designated as the payment office for the contracts.

      h. Joint Contractor/Government Business Process Improvement Team. This 
team is made up of Contractor and government representatives to (1) address 
issues common to all of the SASS Contractors; and (2) support and implement 
web technology to improve the contract business process with a view toward 
lessening the resources associated with day-to-day operational support 
activities.

                SASS Hardware II Contract Management Plan (CMP)

                              Section I - General

      k. DoDIIS and Intelligence Community Activities. DoDIIS Community 
activities that have a requirement to use the SASS Hardware II contracts are 
responsible for:

              (1) Verifying their eligibility to use the contracts against 
the DoDIIS Master Site List (Attachment B to the contracts) and their SIMO.

              (2) Ensuring compliance with the terms, conditions and 
requirements of the SASS Hardware II contracts, the CMP and the CPEP.

7. CONTRACT MONITORING. As a minimum, the COs and the SASS CAST will, in 
concert with the Contractor, utilize the following mechanisms to monitor 
contract activities:

      a. Day-to-Day operations. The SASS CAST will serve as the focal point 
for day-to-day operational contract activities. The resultant communications 
between the SASS CAST, the Contractors, DOAs and customers will provide the 
opportunity to jointly resolve issues as they occur.

      b. Contractor's Monthly Reports. Monthly Reports provide extensive data 
on all aspects of contract activities. This information is paramount to 
addressing any outstanding issues related to Orders, delivery schedules, 
billing/invoicing issues and other problems identified by the Contractor. 
Both Contractor representatives and SASS CAST members will be encouraged to 
ensure these issues are resolved in the course of daily business activity.

      c. Customer Feedback. Customer feedback is essential to monitoring 
contract status. The SASS CAST, in coordination with the Contractors, will
implement action to obtain specific feedback on shipping/receiving of 
materials and customer satisfaction. This may be accomplished by the 
Contractor including a copy of the "Shipping/Receiving Quality Assurance 
Questionnaire" (Enclosure 1-1) with each shipment or eventually having it 
accomplished electronically utilizing web technology. Overall customer 
satisfaction will be assessed by the conduct, on a routine basis, of surveys 
utilizing the "Customer Satisfaction Survey" form (Enclosure 1-2). 
Information obtained via this process will be addressed during the quarterly 
Contract Status Reviews (CSR).

              c. Discrepancy Report System. DS and VaCA management, in 
concert with the CO, Contractors and the SASS CAST, will implement a 
Discrepancy Report System utilizing web technology. The system will provide 
an electronic means for DOAs and customers to submit instantaneous 
discrepancy information to both the contractor and the SASS CAST. These 
discrepancies should be resolved through daily activities among the 
Contractors, customers and

                SASS Hardware II Contract Management Plan (CMP)

                              Section I - General

the SASS CAST. Discrepancy reports and corrective action taken will be on the 
quarterly CSR agenda.

8. QUARTERLY CONTRACT STATUS REVIEW (CSR).

      a. Purpose. The CO will host a quarterly meeting with each Contractor 
to afford the Contractor's management and the CO the opportunity to jointly 
review contract status and address/resolve any outstanding issues; and to 
informally assess the Contractors' performance. The CSR will not supplant 
day-to-day operational activities but rather foster open communications and a 
mutual understanding of contract status at the management level. The 
Contractor will present the CSR with input by the SASS CAST, if appropriate. 
Contractors will have the opportunity to provide an informal self-assessment 
of their performance on the contract to date. During this meeting, the CO and 
the SASS CAST and the Contractor will reach concordance on the Contractor's 
self-assessment.

      b. Participation. At a minimum, Government and Contractor COs and the 
SASS CAST will attend each CSR. Issues and priorities may dictate other 
attendance (e.g., the DIA Chief Information Officer (CIO), other Agency 
management, DOA representation).

      c. CSR Format/Information to Be Presented.

              (1) A standard briefing/presentation format will be established 
by the SASS CAST in concert with the Contractors, which will be used for all 
quarterly CSR. The presentation will, as a minimum, address the following:

                    (a) Ordering Summary (number of orders/value received to 
date, numbers of orders (and value) shipped, number of orders (and value) on 
hold with rationale, summary of compliance with delivery dates to include 
number of orders on which shipping date met/number of orders on which 
shipping date not met, with rationale).

                    (b) Billing Summary (invoices issued and value, invoices 
paid and value, outstanding invoices (amount and how long).

                    (c) Review of Customer Survey/Random Surveys.

                    (d) Status of Action on Customer Discrepancy Reports.

                    (e) Issues and Concerns.

                    (f) Self-Assessment.

9. BUSINESS PROCESS IMPROVEMENT.

      a. DS-AQ and VaCA management intends to employ maximum use of 
electronic and web technology in support of day-to-day operations and 
communication with Contractors, DoDIIS activities and COs to whom ordering 
authority is delegated. DS-AQ is charged with the leadership for this effort, 
in coordination with the Joint Business Process Improvement Team.

      b. Intelink and Internet web technology will be used to:

              (1) Post updates and changes to the Product Tables.

              (2) Request and delegate ordering authority.

              (3) Issue and response to Requests for Quotation (RFQ).

              (4) Monitor Contractor performance information.

              (5) Conduct customer satisfaction surveys.

              (6) Support discrepancy reporting.

              (7) Support Shipping/receiving quality assurance reporting.

              (8) Request and receive Purchase Control Number (PCN).

              (9) Communicate and share general information among the
              Government activities and the SASS Hardware II Contractors.

                         Customer Satisfaction Survey

     The Management Plan for this contract requires that the Government 
evaluate the contractor's performance on a regular basis during the contract 
period.  One performance rating area on which the contractor is evaluated is 
Customer (End User) Satisfaction.  This performance rating area reflects the 
satisfaction of and users with the products provided by the contractor with 
emphasis on completeness of shipments; whether products were operable when 
unpacked; how well discrepancies were resolved; and quality of warranty 
maintenance.  Data on which to perform this evaluation is being obtained 
through the use of this Customer Satisfaction Survey.  In addition to 
providing the Government with information on the contractor's performance, it 
will provide useful feedback to the contractor on performance and provide the 
opportunity to correct problems.

3. CONTRACT USE

     a. Use of the contracts is mandatory for DIA users, but optional for all 
others. "Mandatory use" involves FAR/DFARS provisions, legally binding 
agreements and conditions entered into by DIA as party to the contract.

    b. Multiple contracts have been awarded in each of the RA, Requirements 
will be competed among Contractors within each RA to achieve the economic 
benefits. Table II-2 below identifies each RA, the contract numbers, 
Contractors' name and addresses that will be afforded the opportunity to 
compete within the RA.

          SASS Hardware II Contract Management Plan (CMP)

                   Section III - Product Tables

1. GENERAL.  Among the major objectives of the SASS Hardware II contract was 
the capability for the Government to readily acquire emerging COTS IT 
products as they become available in the marketplace. The contracts require 
Contractors to update their Product Tables to add new and emerging COTS 
technology and to ensure that those products are within the contract scope.

2. POLICY.

   a.    Advance Government approval of Product Table changes is not required. 
All products contained on the Product Tables must be within the scope of the 
Contract Statement of Work. Certification that products meet the mandatory 
specifications set forth in the contracts is required.

   b.    Products offered in response to an RFQ must appear on the Contractors 
Product Table with published price. In the event a Contractor must add a 
product to the Product Table or desires to reduce a price on an existing 
product on his/her Product Table in order to respond to an RFQ, the Product 
Table must reflect the change before a response to an RFQ will be accepted by 
the government.

   c.    COs may not issue an Order for Commercial Items (SF1449) against the 
SASS Hardware II contracts unless the products are listed on the Contractor's 
published Product Tables.

3. PRODUCT TABLE STRUCTURE. The Product Table for each contract is arranged 
by category based on the major Contract Line Item Numbers (CLINs) defined in 
the Statement of Work (SOW). In order to simplify ordering, a mapping between 
contract  CLINs set forth in the SF 1449 (Solicitation/Contract/Order for 
Commercial Items) and the Product Table have been established. For example, 
to order a Low-End Server from the UNIX-Based System RA, the contract CLIN 
would be 0001. The Contractors' Product Table CLINs range from 0100-0199.

4. PRODUCT TABLE MAINTENANCE. Contractors must post product changes to their 
Internet web site and that they provide the VaCa CO the updates within five 
(5) days of making them available on their Internet Product Table. The VaCA 
web site provides "hotlinks" to each Contractor's Home Page for the Product 
Tables. The Government will post changes to Product Tables on the classified 
INTELINK web site. There is the possibility of a time lag of 5-8 days between 
the time that Contractors post Product Table changes on their Internet web 
site and the time the changes are posted on the INTELINK web site. Initially, 
Contractors are required to provide hard copy Product Tables changes where 
products added to facilitate responding to an RFQ. The SASS CAST will work 
with the Contractors to improve the electronic posting, distribution and 
filing of Product Table changes with the objective of "near real time" 
posting and dissemination.

          SASS Hardware II Contract Management Plan (CMP)

                   Section III - Product Tables

5. PRODUCT TABLE AVAILABILITY. The size of the individual Product Tables 
coupled with the frequency of updates and number of contracts dictate that 
the Product Tables be managed, distributed and used electronically. Product 
Tables can be accessed through on the Internet and INTELINK web sites. 
Individual SASS Contractors may provide their Products Tables to their 
customers in hard copy.

               SASS Hardware II Contract Management Plan (CMP)

               Section IV - Delegated Ordering Authority (DOA)


1.  DOA POLICY.

    a.   DOA for the SASS Hardware II contracts will be delegated to fulfill 
IT requirements that are in accordance with the stated contract purpose and 
objectives (refer to paragraphs 1 and 2 of the Statement of Work, Attachment 
A to the contracts and the DoDIIS Master Site List, Attachment B to the 
contracts).

    b.   DOA will be granted only for the entire suite of SASS Hardware II 
contracts and not by individual RA.

    c.   Activities/sites to which ordering authority for the SASS Hardware I 
contracts (MDA908-92-D-1511, 1512 and 1513) was delegated will be initially 
granted SASS Hardware II ordering authority.

    d.   New requests for DOA will be granted subject to agreement to comply 
with the terms and conditions set forth in this CMP (Attachment D to the 
contracts) and those stipulated in the DOA Agreement.

    e.   Ordering authority will be revoked by the Virginia Contracting 
Activity (VaCA) if it is determined that any of the terms and conditions set 
forth in this CMP and/or those stipulated in the DOA Agreement are violated.

    f.   All Orders for Commercial Items (SF 1449) issued by a DOA must 
contain a Purchase Control Number (PCN) issued by the SASS CAST.  Contractors 
may not accept an Order issued by a DOA if that Order is not annotated with a 
PCN issued by the SASS CAST.

    g.   PCNs will not be issued for the purpose of issuing an RFQ to the 
Contractors within a RA. PCNs will be issued only when the CO has made an 
award determination.

    h.   Upon receipt of an Order, Contractors must validate the PCN with the 
SASS CAST prior to fulfilling the Order.

    i.   Only contracting organizations with DOA may issue Orders against the 
contracts.

2.  SUBMISSION OF REQUESTS FOR DOA.

    a.   DOA will be requested from the VaCA by completing, signing and 
         submitting the Request for Delegated Ordering Authority enclosure 
         IV-1. The chief of the contracting organization must sign the 
         request or an official designated to sign for him/her.

               Section IV - Delegated Ordering Authority (DOA)


    b.   The VaCA will review and approve requests for DOA in writing.

    c.   Contracting organizations granted DOA for support of DoDIIS and 
designed Intelligence Community activities will be posted on the VaCA SASS 
web site on Internet and the DoDIIS Intelink web site. Individual contracts 
will not be amended to reflect DOA.

3.  PURCHASE CONTROL NUMBER (PCN) PROCEDURES.

    a.   General. All orders for Commercial Items (SF 1449) issued by a DOA 
must be annotated with a VaCA issued unique identifier. The PCN provides an 
administrative mechanism through which the SASS CAST can be assured of 
maintaining the current status of all Orders is issued against each contract. 
The SASS CAST will also use PCNs to monitor and track contract use, assist in 
resolution of problems and maintain an accurate record of dollars expended.

    b.   PCN Structure.  PCNs will be composed of an alphanumeric identifier 
made up of a RA identifier, a Contractor identifier and a one-up sequence 
number, the combination of which provides a unique identifier. Table IV-1 
below depicts RA and Contractor Identifiers.

                 SASS HARDWARE II CONTRACT MANAGEMENT PLAN (CMP)

                             SECTION V - COMPETITION

1.  OBJECTIVE.  A major objective of the SASS Hardware II contracts is to 
achieve the economic benefits of continuing competition. All SASS Hardware II 
Contractors will be afforded THE OPPORTUNITY TO BE CONSIDERED FOR AWARD OF 
DELIVERY ORDERS BY REVIEW OF PUBLISHED PRODUCT TABLES FOR REQUIREMENTS UNDER 
THE SMALL ACQUISITION THRESHOLD (SAT) AND COMPETITION, BY RFQ, OF 
REQUIREMENTS FALLING ABOVE THE SAT.

2.  IDENTIFICATION OF REQUIREMENTS

      a.  GENERAL.  Competition of requirements at the Order level among the 
Contractors within each RA dictate that IT requirements be identified in 
terms of:

             (1) REQUIREMENTS AREA (RA).

                  UNIX-Based System.
                  PC-Based System
                  Specialized System

             PERIPHERALS
                  TEMPEST IT
                  Communications Components

     (2)  FUNCTIONALITY.  The Contract for each RA identifies Requirements by 
Functionality and Contract Line Item Number(s) (CLIN). For example, within 
the PC-Based Systems RA, CLIN 0001 is identified by "3000 PC Servers 
(PC-Based Systems)". CLIN 0001 further identifies Servers as "Low End, 
Mid-Range" and "High End" and provides the minimum requirement which must be 
met by specific products offered under each CLIN by the SASS Hardware II 
Contractors in their Product Tables.

      (3)  WARRANTY AND MAINTENANCE REQUIREMENTS.  The SASS Hardware II 
contracts were awarded as "commercial Item" contracts as defined by the 
Federal Acquisition Regulation (FAR), Part 12. Accordingly, warranty and 
maintenance terms and conditions may differ vastly among the contracts within 
an RA. Best value determinations in evaluating responses to RFQs should 
consider warranty and maintenance terms and conditions as well as warranty 
periods. RFQs should include the Government's Warranty and Maintenance 
Requirements.

     (4)  YEAR 2000 (Y2K) COMPLIANCE REQUIREMENTS.  There are products in the 
marketplace, which are not yet Y2K compliant. Because Y2K compliance is a 
Government mandate, the SASS Contractors are required to depict in their 
Product Tables whether Y2K compliance is applicable to each listed product and 
whether or not that product is certified as Y2K compliant. It should not just 
be assumed that ALL products listed in the Product Tables are Y2K compliant. 
There may be those

<PAGE>

                 SASS HARDWARE II CONTRACT MANAGEMENT PLAN (CMP)

                             SECTION V - COMPETITION

rare occasions when an operational intelligence support requirement can only be 
satisfied by a product is which not Y2K compliant. Because Contractors can 
offer products that may not be Y2K compliant in response to a RFQ. RFQs must 
include the Government's Y2K compliance requirements.

     b.  SPECIFIC PRODUCT REQUIREMENTS.  There will be cases when requirements 
are for specific products:

         (1)  COMMON OPERATING ENVIRONMENT (COE).  Previously awarded 
contracts and dedicated efforts to achieve a level of standardization in the 
products supporting military intelligence Community overall, and intrinsic to 
achievement of system migration goals have resulted in formation of product 
specific COE support lists. Many of these products are identified in the 
Baseline Inventory Document, which is Attachment C to the contracts. There 
may be cases where infusion of products other than what is already operational 
within a COE is not in the best interests of the Government (e.g., negatively 
impacts interoperability, compatibility and systems integration). IN THESE 
CASES, ACQUISITION AUTHORITIES SHOULD GIVE EVERY CONSIDERATION TO COMPETING 
THE REQUIREMENT IF IT IS FELT THAT THE CONTRACTORS WITHIN A RA MAY BE ABLE TO 
OFFER THE SPECIFIC PRODUCT OR INCLUDE IT IN THEIR PRODUCT TABLES.

         (2)  GOVERNMENT MANDATE.  There are cases where use of specific 
products is mandated. For example, use of specific computer operating systems 
has been mandated for selected DoD programs. However, this mandate should not 
be construed to mean the requirement must be solicited sole source because:

         (a)  There may be more than one hardware platform that meets the 
minimum mandatory requirements of the Contract Statement of Work and supports 
the mandated operating system.

         (b)  There may be more than one Contractor within an RA that can 
offer a hardware platform that meets the minimum mandatory requirements of 
the RFQ and supports the mandated operating system.

Consideration will be given to COI/COE concerns, principles of 
standardization and interoperability, compatibility and integration, while, 
at the same time, striving for cost efficiencies achieved from competition. 
To the maximum extent possible, COs should AFFORD EACH CONTRACTOR WITHIN A 
GIVEN RA EQUAL OPPORTUNITY TO BE CONSIDERED FOR AWARD.

         (c)  USE OF ORDERING GUIDE (OG).  The SASS Hardware II OG provides 
expanded guidance on identifying and processing requirements for competitive 
acquisition. Anyone anticipating use of the SASS Hardware II contracts should 
consult OG prior to processing a requirement for competitive acquisition.

                 SASS HARDWARE II CONTRACT MANAGEMENT PLAN (CMP)

                             SECTION V - COMPETITION

3.  COMPETITION

     a.  GENERAL.  In the initial phases of contract implementation, all 
requirements regardless of dollar value will be completed among Contractors 
within the appropriate RA. This will provide the Contractors the opportunity 
to gain a better understanding of the Government's overall requirements and 
adjust their Product Tables accordingly. As contract use evolves and 
automation technologies make Product Table comparison more efficient, it is 
anticipated that COs will make use of automated technology to make 
comparative analysis of the Product Tables of Contractors within a RA as 
opposed to issuing and RFQ. This will reduce the administrative burden and 
expense to both the Government and Contractors in issuance and response to 
RFQs. 

     b.  REQUIREMENTS BELOW THE SIMPLIFIED ACQUISITION THRESHOLD (SAT). COS ARE 
STRONGLY ENCOURAGED TO exercise their management and decision prerogatives on 
DO requirements falling below the SAT by comparing each Contractor's Product 
Tables for source selection rather than issuing an RFQ to each of the 
Contractors within a RA. Comparative use of the Product Tables constitutes 
affording each Contractor the opportunity to be considered for award as 
required by the FAR.

     c.  REQUIREMENTS ABOVE THE SAT.  ALL REQUIREMENTS ABOVE THE SAT SHALL BE 
COMPETED. THIS GUIDANCE IS NOT APPLICABLE TO "DIRECTED" ORDERS AS DEFINED BY 
LOCAL CONTRACTING ACTIVITY PROCEDURES.

     d.  REQUIREMENTS FOR PRODUCTS NOT ON PRODUCT TABLES.  Rapidly emerging 
and evolving technology may occasionally result in products and or 
functionality being available in the market place but not yet on the 
Contractor's Product Tables. In instances where required products do not 
appear on a Contractor's Product Table, the requirement should be competed 
among all of the Contractors within the RA. This is because the Contractors 
have the opportunity to update their Product Tables prior to responding to an 
RFQ affording the Government the benefit of competition.

     e.  REQUIREMENTS FOR BUNDLED SYSTEMS. STRONG CONSIDERATION SHOULD BE 
GIVEN TO COMPETING REQUIREMENTS FOR BUNDLED SYSTEMS AMONG ALL CONTRACTORS 
WITHIN THE APPLICABLE RA IF THE CO FEELS THAT BETTER PRICING CAN BE ACHIEVED 
OR THAT THE GOVERNMENT'S REQUIREMENT CAN BEST BE FILLED AFFORDING ALL 
CONTRACTORS THE OPPORTUNITY TO OFFER A SOLUTION TO A PARTICULAR IT 
REQUIREMENT.

4.   INDIVIDUAL ORDER LEVEL SOURCE SELECTION.  Award of Orders should be 
based on a "best value" determination that addresses, as a minimum, the 
following:

     a.  CAPABILITY TO COMPLY WITH ORDER SPECIFIC REQUIREMENTS.  
Consideration should be given to whether or not the Contractor's response to 
an RFQ meets the

<PAGE>

                 SASS HARDWARE II CONTRACT MANAGEMENT PLAN (CMP)

                             SECTION V - COMPETITION

specific requirements CONTAINED IN THE RFQ such as Y2K compliance, stated 
system configuration, warranty, capability to meet expedited requirement, etc.

     b.  PAST PERFORMANCE.  The SASS Hardware II Contractors have a history 
of favorable past performance, which was a factor for contract award.  
However, as the contracts are used, information on each Contractor's 
performance under the SASS II contracts will be collected and made available 
in accordance with the CPEP. COs, when making a best value determination, may 
use a Contractor's performance on the SASS contracts themselves as an 
evaluative factor in source selection at the Order level.

     c.  WARRANTY.  Warranty terms and conditions vary among the contracts. 
Items of consideration include when warranty commences (upon delivery, 
installation, etc.), length of the warranty period, whether it is on-site or 
depot, etc.

     d.  PRICE.  


<PAGE>
                SASS HARDWARE II CONTRACT MANAGEMENT PLAN (CMP)
 
           SECTION VI - CONTRACTOR PERFORMANCE EVALUATION PLAN (CPEP)
 
1. PURPOSE.  The purpose of this Contractor Performance Evaluation Plan (CPEP)
is to establish responsibility and procedures for evaluating the performance of
the Systems Acquisition and Support Services (SASS) Hardware II Contractors.
 
2. REFERENCE.
 
    a. Federal Acquisition Regulation (FAR) 42, Subpart 42.15, Contractor
Performance Information.
 
    b. Systems Acquisition and Support Services (SASS) Hardware II Contracts.
 
INTRODUCTION.
 
    a. General. Past performance was the major criteria used by the Government
in making the SASS Hardware II contract awards with the belief that past
performance is a major indicator of future performance. Contractor performance
will continue to be a factor in award of Orders against the contracts.
 
    b. Importance of Communications. Quality service and products are the goals
of both the Government and the Contractors. Open and frank communication between
the two parties is paramount to attainment of this goal and will provide
opportunities to proactively address problem areas, identify successful areas to
sustain, and identify business process improvements. Continuous, well documented
discussion and resolution of any problem areas will lessen the burden on
Government personnel preparing performance evaluation reports, as well as lessen
the chances that the results of the evaluation are unexpected by the
Contractors.
 
    c. Use of Performance Information. All aspects of each SASS Contractor's
performance will be evaluated with a view toward using the results as (1) a
source of past performance information in making a best value determination for
issuance of Orders against the contracts; (2) an evaluative factor in the
Government's consideration of contract option renewal; and (3) a source of
information from which to respond to requests from other Government agencies for
past performance information.
 
    d. Collection of Performance Information. Performance evaluation will be a
continuing process based on open communication between the Contractor, COs, SASS
CAST and customers. Information will be derived from day-to-day operational
activities; Monthly Reports; Customer Satisfaction and/or Random Surveys; the
Discrepancy Reporting System; Quarterly Contract Status Review (CSR) and the
Contractor's self-assessment; and feedback provided by contracting organizations
holding a DOA. Every effort will be made to ensure that all information is
shares between the Government and the Contractor.

<PAGE>
                SASS HARDWARE II CONTRACT MANAGEMENT PLAN (CMP)
 
           SECTION VI - CONTRACTOR PERFORMANCE EVALUATION PLAN (CPEP)
 
    d. Frequency of Evaluation. Continuous communications and performance
measurement during execution of the contract will provide information necessary
for completing formal annual performance evaluations. Results of the quarterly
status update meeting which centers on the Contractor's activities during the
previous quarter are critical not only to effective contract management and
administration, but, just as importantly, it reflects the Contractor's
performance. During the CRS, Contractors will provide an informal performance
self-assessment at which time the Contractor and Government will reach
concordance in the assessment. It is reasonable to expect that if the Contractor
performs consistently, and the Government and the Contractor are in concordance
with the quarterly informal performance assessment, then this will be reflected
in the formal annual Contractor Performance Evaluation Report (CPER), a copy of
which is at enclosure VI-1. Because the annual interim reports reflect
performance over the life of the contract to date, the last interim report will
serve as the final CPER.
 
4. RESPONSIBILITIES.
 
    a. Contracting Officer (CO). The CO is responsible for:
 
        (1) Oversight of the Contractor performance evaluation process.
 
        (2) Completion of the CPERs and providing it to the Contractor for
    comments.
 
        (3) Obtaining higher level review of the Contractor's performance
    evaluation in the event the Contractor and the CO are unable to agree upon a
    rating.
 
    b. Delegated Ordering Authorities (DOA). Contracting organizations to which
ordering authority has been delegated is responsible for:
 
        (1) Providing feedback on Contractor performance.
 
        (2) Completion and submission of an informal CPER.
 
        (3) Conducting/completing random Customer Satisfaction Surveys and
    reporting the results to the VaCA.
 
        (4) Ensuring Shipping/Receiving Quality Assurance Questionnaires are
    completed for each Delivery Order.
 
        (5) Maintaining continuous performance measurement files on each
    contract, to include correspondence with the Contractors, minutes of
    meetings, discrepancy reports and closure, Customer Satisfaction Surveys,
    and Shipping/Receiving Quality Assurance Questionnaires.

           SECTION VI - CONTRACTOR PERFORMANCE EVALUATION PLAN (CPEP)
 
    c. SASS Contract Administration Support Team (SASS CAST). The SASS CAST is
responsible for:
 
        (1) Maintaining continuous performance measurement files on each
    contract, to include correspondence with the Contractors, minutes of
    meetings, discrepancy reports and closure, Customer Satisfaction Surveys,
    and Shipping/Receiving Quality Assurance Questionnaires.
 
        (2) Interfacing with DOAs to obtain required Contractor performance
    evaluation information.
 
        (3) Monitoring the evaluation process keeping the CO and Contractors
    apprised of any information, which adversely affects the evaluation process.
 
        (4) Assisting the CO in preparation of the annual CPER.
 
        (5) Scheduling and coordinating attendance/agenda for Quarterly Contract
    Status Update meeting and providing copies of the briefing to DOAs.
 
        (6) Making available to DOA COs electronic forms required for Contractor
    evaluation.
 
    d. Contractor. The Contractor is responsible for:
 
        (1) Providing continuous feedback to the COs and the CORs through the
    conduct of normal business with the Government.
 
        (2) Reporting and assisting in resolution of problems surfaced during
    execution of the contract.
 
        (3) Presenting a quarterly Contract Status Review (CSR).
 
        (4) Participating in regular meetings with the CO/CORs and Customers to
    proactively address problem areas, identify successful areas to sustain, and
    identify business process improvements.
 
        (5) Following up delivery orders with periodic Customer Satisfaction
    Surveys and reporting results at the quarterly CSRs.

<PAGE>
                SASS HARDWARE II CONTRACT MANAGEMENT PLAN (CMP)
 
           SECTION VI - CONTRACTOR PERFORMANCE EVALUATION PLAN (CPEP)
 
        (6) Reviewing the CPER.
 
           (1) Sign and return the CPER within ten (10) days of receipt from the
       CO acknowledging receipt and review. If the Contractor fails to sign the
       CPER, the CO may annotate the report and finalize the evaluation.
 
           (b) Submit comments, rebuttal or additional information, if any, with
       the signed CPER.
 
5. PROCEDURES.
 
    a. Quarterly Contractor Self-Assessment. The last item of the Contractor's
standard presentation for the CSR will be a self-assessment that affords the
opportunity for the Contractors to informally rate themselves against the
performance rating areas identified in the contract. The rating definitions and
guidelines contained in the CPER (Enclosure VI-1) will be used for this
self-assessment utilizing the following presentation format:
 
              Quarterly Self Assessment - (Contractor Name), (date)
--------------------------------------------------------------------------------
Rating Area                     Rating                   Comment/Rationale
--------------------------------------------------------------------------------
Quality

--------------------------------------------------------------------------------
Timeliness

--------------------------------------------------------------------------------
Business Relations

--------------------------------------------------------------------------------
Customer
Satisfaction
--------------------------------------------------------------------------------
 
Once the rating is presented, Contractors will have an opportunity to
substantiate his rating. Subsequent discussion will be directed towards
attainment of Government and Contractor concordance in this informal assessment.
Given the fact that all information regarding the Contractor's performance is
known by the Government and all information available is shares by both parties,
reaching concordance should not be difficult. There should be no surprises
during this process.
 
    b. DOA Assessment of Contractor Performance.

        (2) DOAs will be (a) provided copies of slides used in the quarterly CSR
    (which will include the Contractor's self-assessment); and (b) afforded the
    opportunity to comment.
 
    c. Annual Contractor Performance Evaluation Report.
 
        (1) Utilizing the information acquired via the mechanisms and processes
    described above, the CO will, in coordination with the SASS CAST and the
    Contractor, prepare the annual CPER in accordance with this CPEP and the
    contract. The CPER will be provided to the Contractor for review and
    signature not later than 30 April of each year.
 
        (2) The Contractor will be given five (5) work days to review, sign and
    return the completed CPER.
 
        (3) In the event the Contractor submits a CPER rebuttal and an agreement
    cannot be reached between the Contractor and the CO, the CO will raise the
    issue to the next highest management level within the VaCA. The VaCA will
    provide the Contractor with a written decision within fifteen (15) workdays
    from receipt of the Contractor's CPER rebuttal.
 
6. MAINTENANCE OF COMPLETED EVALUATIONS. Completed CPERs will be maintained in
the contract file. The VaCA will establish a central repository for all CPERs.
DIA's objective is to make as much of this information as possible available via
Internet, with restrictions on access as appropriate. Interim evaluations will
be retained for the duration of the contract and will be included with the final
evaluation in the file.
 
7. RELEASE OF INFORMATION. The completed evaluation will not be released to
other than Government personnel and the contractor whose performance is being
evaluated during the period the information is being used to provide source
selection information.
