Reporting Methods
--------------------------------------------------------------------------------

Status Reports
--------------------------------------------------------------------------------

      Predictive Systems' team will provide a weekly status report in electronic
      format to the First Union Program Manager. The report form will be brief,
      listing any items that were completed that week and the open items for the

Proposed Statement of Work
--------------------------------------------------------------------------------

[***]
--------------------------------------------------------------------------------
This SOW details the activities of Predictive Systems' [***]. The team will be
responsible for implementing enhancements to the current system to support new
requirements that have emerged since the original [***] was developed. The [***]
functionality enhances the current system functionality in the areas depicted in
Table 1.

[***]
--------------------------------------------------------------------------------
The [***] system implementation will involve some up-front analysis and
requirements review work followed by the implementation of the identified
functionality. However, unlike a ground-up integration project, and because the
current production [***] serves as the basis for the development of this phase
of enhancements, the [***].

Under the plan recommended in this SOW, the [***] system enhancements will
be delivered in stages, with the most important functionality delivered first.
This staged implementation model was successful during the [***] deployment
cycle. Figure 1 provides a conceptual model for the staged delivery approach.

Description of Project Tasking
--------------------------------------------------------------------------------
Because the most important functionality is delivered first, the [***] users'
critical needs can be met sooner. Each staged delivery presents tangible
evidence of the project's progress and gives the end-user a chance to review the
interim products and provide feedback to the project team prior to the delivery
of the final system. This methodology allows a series of adjustments to be made
to the system in a controlled fashion, with user input, rather than waiting to
the end of the project to make a massive amount of change. In a series of staged
deliveries, the project progresses along a path that includes the steps
described in the rest of this section .

Requirements Review and Workflow Definition

The requirements review and workflow definition stage of the [***] deployment
involves spending some time with the end-user community to develop a prioritized
list of functional requirements to be deployed in a staged fashion. The [***]
staff has been exposed to the [***]; therefore, a fast-track approach for
requirements review can be utilized by building upon the most desirable
functions from the system and developing new functionality where required.
Although much of the functionality that has been implemented during the [***]
effort was defined during the [***] design task, many of the requirements have
changed over time. However, rather than conducting a lengthy requirements review
and workflow definition process, this task will be conducted as an on-going
iterative process.

Define Requirements for the [***]
--------------------------------------------------------------------------------
Prior to development commencing on new [***] functions, Predictive Systems'
consultants will collect and document requirements, review the requirements with
the end-users, and develop a design and project plan to be reviewed with Qwest
prior to getting approval to move forward with the development process. For the
most part, this project will be executed [***]. However, in some cases, the
requirements need to be defined prior to estimating resources and timelines.
These areas include:

o [***]

o [***]

o [***]

Part of the deliverables of the requirements definition phase is an estimate of
the resources, cost and schedule required to implement the desired
functionality.

          (the time and day have yet to be determined). The meeting will focus
          on reviewing any work that was performed by the Qwest/Predictive
          Systems team and reviewing any open items that are scheduled for the
          next week's period. This meeting will also provide a platform for
          reviewing any new issues or additional project requirements.

Assumptions
--------------------------------------------------------------------------------

          In determining the scope of work for this project, Predictive Systems
          made the following assumptions:

          []   Timely access to Qwest personnel and technical information will
               be provided in order to meet project milestones and to stay
               within the bounds of the costs estimates.

          []   Qwest will provide timely review of Predictive Systems
               deliverables. Feedback will be in written format.

          []   Qwest will designate a staff member to be dedicated to the
               Predictive Systems team for training. Predictive Systems will be
               granted reasonable access to this person during regular business
               hours.

          []   Qwest will designate a formal point of contact (POC) for the
               duration of the project. This POC will have signature authority
               for deliverable acceptance.

          []   Qwest will provide Predictive Systems with access to a
               development environment.

--------------------------------------------------------------------------------

Status Meetings
--------------------------------------------------------------------------------

There will be weekly status meetings with Qwest on the overall project. The
meeting should be held at the same time of day every week (the time and day have
yet to be determined). The meeting will focus on reviewing any work that was
performed by the Qwest/Predictive Systems team and reviewing any open items that
are scheduled for the next week's period. This meeting will also provide a
platform for reviewing any new issues or additional project requirements.

Project Schedule
--------------------------------------------------------------------------------

Assuming that independent tasks are performed at the same time, this project
will take approximately [***] calendar months to complete. This schedule is
dependent upon the availability of information and access to Qwest staff as
required.

Project dates are subject to change based on project implementation details and
will be provided to the Qwest Program Manager, as modifications are required.
Weekly written status reports will be provided to Qwest indicating progress made
since the last reporting period, progress to date, issues and concerns, and
action items (new or outstanding).

A detailed project plan will be delivered at the conclusion of the first week of

Assumptions
--------------------------------------------------------------------------------

In determining the scope of work for this project, Predictive Systems made the
following assumptions:

o Any work not specified in this SOW is considered out of scope. Predictive
  Systems cannot guarantee that new work or changes to the scope defined in this
  SOW can be completed by the stated due date. All changes to the scope of this
  SOW must be agreed to by Predictive Systems and Qwest.

o Development environment not currently available, i.e. the short-term
  development will be done on the production box. [***]

o Timely access to Qwest personnel and technical information will be provided in
  order to meet project milestones and to stay within the bounds of the costs
  estimates.

o Qwest will provide timely review of Predictive Systems deliverables. Feedback
  will be in written format.

o Qwest will designate a formal Point of Contact (POC) for the duration of the
  project. This POC will have signature authority for deliverable acceptance.
