 per month). The use of "Extrapolated Planned Sampling" to either assess the
contractors performance or to take deductions from the contract price is
contrary to NAVFACENGCOM policy.
One Hundred percent (100%) - Inspection - One hundred percent inspection is a
surveillance method whereby all the occurrences in the population of services
is inspected .
Performance Evaluation - A performance evaluation is an evaluation of the
contractors performance carried out in accordance with the Contracting Manual
P-68.
Requirements Summary - The performance requirements summary (PRS)
shows contract requirements the component work requirements related to each
contract requirement, the price of each work requirement as a percentage of
the associated contract requirement, the standard of performance, and the
maximum allowable defect rate (MADR) for each work requirement.
Performance Work Statement - The performance work statement (PWS) consists of
the definitive or descriptive words identify- the subject matter of the
contract referred to as the specifications or work statement. When the
Uniform Contract Format is used the PWS consists of Section C and the related
attachments in Section J.
Planned Sampling - Planned sampling is designed to evaluate a part but not
all of a contractor requirement. This is a type of sampling which a
particular contract requirement (or subset of work requirements) is subjected
to regular, periodic observation. The observed defect rate found during
planned sampling only represents the defect rate for the sample chosen, and
the observed defect rate cannot be extrapolated to give the defect rate for
the entire service being performed. The extrapolation of the planned
sampling to either assess the contractor's performance or to take deductions
to the contract price is contrary to NAVFACENGCOM policy. The defect rate,
when planned sampling is used, is calculated by dividing the total of all
defects (both within and without the sample) by the total population.
Alternatively, the defect rate may be expressed as the number of defects
which occurred over a specified period.
Population - The population is the total number of occurrences of an
individual work requirement (sub-task) or service carried out over a specific
period of time. When similar occurrences differgreatly in cost or scope,
they should be split into separate populations.
Population Size - The population size is the number of occurrences in the
population.
Procuring Contract Officer - The Procuring Contract Officer (PCO) is
responsible for the procurement of goods and services.
Quality Assurance - Quality assurance (QA) is the management of the output
quality and responsiveness of a facility support contractor and starts with
the early stages of quality development runs through every phase to
