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

Important Term
Service Object Initial State
Service Process (Tasks)
Service Object Final State
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

Developing a Performance Work Statement – 10 Steps
1. Identify the object(s) you want the contractor to change2. 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 standards5. Write and organize the list of service tasks6. Write the performance requirements summary7. Write the other sections of the work statement (Scope,
References, Deliverables)8. Prepare a table of contents, if PWS is more than 10 pages9. Prepare document cover, if PWS is attachment to contract10. Publish the PWS
the challenge !

Step 3 – Work Breakdown AnalysisThe Most Important Step
OBJECT
PART A PART B
OBJECTWhat are the parts of this?Does it need to be treated separately?
What are the parts of these? Do they need to be treated separately?
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 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

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