## Intro - Performance-Based Contracting

- Structure all aspects of the acquisition around the purpose of the work
- Set forth contract requirements in clear, specific, and objective terms with _measurable outcomes_
- Stay away from:
- Specifying manner by which the work should be performed
- Broad and imprecise statements of work

## Intro - Performance-Based Contracting

- Intro - Performance-Based Contracting

- Describe requirements in terms of _results_ required
- Service result = change in state of affairs
-                           = condition you want to exist after the 				contractor has done the work
- Use _measurable_ performance standards
- Quality, timeliness, quantity, etc.
- _Deducts_ - Specify procedures for reductions of fee or reductions price of FP contract when services are not performed or do not meet contract requirements
- _Incentives_ – Use where appropriate, when they offer significant advantages

## Important Term

- _Service Object_ – The thing that the contractor works on
- A system, an individual thing, a person (e.g., student), an organization, a process, or information

- Student knows nothing about PBC

- Teach student about PBC

- Student gains new knowledge of PBC

- System is not functioning properly

- Repair the system

- System functions as it should

## Developing a Performance Work Statement – 10 Steps

- Identify the object(s) you want the contractor to change
**State what you want the contractor to do to the object(s)**
**Analyze each service object to identify the object parts that require separate treatment (**_**NO VERBS**_**)**
**Develop performance standards**
- Write and organize the list of service tasks
- Write the performance requirements summary
- Write the other sections of the work statement (Scope, References, Deliverables)
- Prepare a table of contents, if PWS is more than 10 pages
- Prepare document cover, if PWS is attachment to contract
- Publish the PWS

- the challenge !

## Step 3 – Work Breakdown AnalysisThe Most Important Step

- 26 Jan 05

## Product of Step 3 – Work Breakdown Structure or WBS

- Product of Step 3 – Work Breakdown Structure or WBS

- The WBS is the underlying framework of a PWS

## Step 4 – Develop Performance StandardsThe Most Difficult Step!

- Step 4 – Develop Performance StandardsThe Most Difficult Step!

- _Performance standard_ = (Attribute of the service object that you want the contractor to change) + (a specific attribute description or measurement)
- Floors must be free of all visible dirt and refuse
- Each wastebasket must contain a clean plastic liner and be empty of refuse
- 90% of all incoming calls must be answered within three rings

- Develop a performance standard for each element at the lowest of work breakdown

- 26 Jan 05

## Step 4 – Develop Performance Standards

- For each of the WBS’ lowest level elements, begin the performance standard with:
- “_**The performance standard is met when**_ . . .”
- Then continue the standard with one or more of the following methods of evaluation:
**	**_**-What you SEE, SMELL, HEAR, TASTE or FEEL is the determinant of acceptability**_
- [Maintain Objectivity of Evaluation Standards!]

## Step 5 – Write the List of Tasks

- Each task statement begins with a verb and says:  _*Do*_* this *_*to*_* this . . .*
- Two parts:
- Verb describing what the contractor must do.
- Noun phrase describing the service object

- ENSURE THAT YOU CAN EXPLAIN WHAT THE VERB MEANS AND NEVER INCLUDE MORE THAN ONE VERB IN A TASK STATEMENT!!!!!!!!!!!!!!!!!!!!

## Step 6 – Write the Performance 			       Requirements Summary

| Performance Requirements Summary |  |  |  |
| --- | --- | --- | --- |
| Sample Performance Standards |  |  |  |
| Task # | Task Description | Performance Indicator | Required Performance Measurements |
| 3.1 | Clean floors daily | State of Cleanliness | Floors must be free of all visible dirt and refuse |
| 3.2 | Empty wastebaskets daily | Contents | Each wastebasket must contain a clean plastic liner and be empty of refuse. |
| 4.1 | Teach monthly class on how to write a PWS  | % of students who pass course | 98% of students must pass the PWS course |
| 5.1 | Keep the system in an operational state | System availability | The system availability shall be greater than or equal to 99.5% |
| 5.2 | Install virus definition updates to all computers on the network | Timeliness | Upon receipt of virus definition updates from the vendor, install those updates to all computers on the network within 24 hours |
