For Official Use Only How To Write a Performance Work Statement(PWS) Paula Ireland & Chuck Beatty NGA Acquisition Center (NAC) 26 Jan 05 For Official Use Only
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
Service Object Initial State Service Object Final State Service Process (Tasks) 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 !
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 B PART A 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 3 – Work Breakdown AnalysisThe Most Important Step
Product of Step 3 – Work Breakdown Structure or WBS The WBS is the underlying framework of a PWS

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