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
• 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

Developing a Performance Work
Statement – 10 Steps
1. Identify the object(s) you want the contractor to change
2. State what you want the contractor to do to the object(s)
3. Analyze each service object to identify the object parts
that require separate treatment (NO VERBS)
4. Develop performance standards
5. Write and organize the list of service tasks
6. Write the performance requirements summary
7. Write the other sections of the work statement (Scope,
References, Deliverables)
8. Prepare a table of contents, if PWS is more than 10 pages
9. Prepare document cover, if PWS is attachment to contract
10. Publish the PWS

Step 3 – Work Breakdown Analysis
The Most Important Step
What are the parts of this?
Does it need to be treated
separately?
OBJECT
OBJECT
What are the parts of
these? Do they need to be
treated separately?
PART A
PART B
At each level of breakdown the parts must be mutually exclusive
and collectively exhaustive of the next higher level.
Furthermore, there must be no overlap among the parts at a
particular level and nothing must be left out

Step 4 – Develop Performance Standards
The 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

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!!!!!!!!!!!!!!!!!!!!
