QUALITY ASSURANCE SURVEILLANCE PLAN (QASP). This plan will be used to assure the Government that the work specified under this contract is completed satisfactorily. This plan is included for information purposes and will not be made part of any resulting contract. Payment analysis will be conducted by using the Random, Periodic Inspection, or 100% sampling methods; however, the Government has the right to change or modify surveillance methods at its discretion.

2.

DEFINITIONS.

a.

Acceptable Quality Level (AQL). The AQL is a predetermined value selected and used by the Government Quality Assurance Inspector to distinguish between satisfactory and unsatisfactory performance. For evaluation by Random sampling, AQLs are stated in percentages (i.e., 95%, 90%, etc.) in accordance with Table I. The AQL table has three parts: Population Size, sample size, and the allowable reject level.

i.

Population Size - the total number of required services from which a sample is to be drawn. Example: 505 picnic sites to be cleaned each day x 20 cleaning days/mo. (inspection period) = Population Size of 10,000.

ii.

Sample - the number of samples to be taken. Example: AQL is 90% and Population Size is 10,000 = Sample of 26.

iii. Reject level - the allowable margin of error allowed the Contractor under the Random sampling method. When the observed total number of defects per inspection period is equal to or below the

Reject Level, the work will be considered satisfactory; if above, the work will be considered unsatisfactory. An unsatisfactory rating will require corrective action and/or deductions.

Notification of unsatisfactory performance will be provided in the form of a Contractor

Discrepancy Report (CDR). Example: AQL of 90%, Population of 10,000, Sample Size of 26 = Reject Level of 6.

PAYMENT ANALYSIS

a.

Random Sampling Method: Surveillance based on random sampling is a Government quality assurance evaluation method designed to evaluate some part, but not all, of the contract service requirements being monitored. This method is based on statistical theory and estimates the Contractor's overall level of performance for a given service requirement. Random sampling is considered where there is a large, homogeneous population and 100% surveillance is not feasible. Surveillance of the results of a scheduled service is based on samples from finished work using the Random Sample Table. These results are compared to the specified performance standards.

i.

Monitoring: Inspection of all services performed under this method will be conducted according to a schedule developed by the Government. Inspection samples will be selected randomly from each lot. Only those items appearing in the random samples will be used for evaluating performance.

ii. Deductions: Once a random sample has been taken of a lot, and the number of defective items exceeds the Reject Level for that lot, a deduction will be calculated as follows:

a) Population Size is 10,000 units.

b) Monthly contract price for cleaning picnic sites is $5,050.

c) Sample size, using an AQL of 90%, is 26.

d) Number of defects in the sample is 8 (Reject Level is 6)

e) Percentage of defects is 30.8% (8 +26 = 0.308) f) Deduction from the current month's invoice is $1,555.54 ($5,050 x 0.308 = $1,554.54).

b.

Periodic Inspection Method. Surveillance by Periodic Inspection, like Random Sampling, is designed to inspect some part, but not all of the contract service requirements being monitored. Periodic Inspection under this plan will differ from Random Sampling only in the way in which samples are selected. Periodic inspection will be used in lieu of random sampling when the population size is not large enough to make the random tables practical or the service is not critical enough to warrant 100% inspection or to avoid excessive travel and loss of productive time for the inspector. The results of these inspections, like random sampling, are then compared to the specific performance standards.

EXAMPLE: The inspector is to inspect bulletin boards. Bulletin board population size is only 38 and occurs in only one park and the headquarters area. If the random sampling method determines that the inspector must inspect the cleaning service of restrooms in a particular park that contains a bulletin board, then the inspector may chose to inspect the cleaning of that bulletin board in that same park rather than drive to another park to make a separate, similar inspection.

1.

Monitoring: Inspection of all services performed under this method will be conducted according to a schedule developed by the Government. The Government may, however, choose facilities it wishes to inspect without randomly selecting. Only those samples will be used for evaluating performance.

ii. Deductions: Once a periodic inspection has been performed, and the number of defective items exceeds the Maximum Allowable Deviation from Requirement for that population (see Table 2), a deduction will be made based on the following example:

a) Contract price for bulletin boards is 19.00

b) Number in sample is 15 services/month

c) Number of deviations/defects in the sample is 6 (Max. Allowable Deviation is 4)

d) Percentage of sample defective is 40% (6/15 = 0.40)

e) Deduction for the current month is $7.60 ($19.00 x 0.40 = $7.60) c.

100% Inspection Method: Surveillance by this method requires that every occurrence of a performed service be monitored. Contract requirements using these evaluations are generally that occur infrequently, are essential, or are costly to perform. These results are then compared to the specific performance standards.

i.

Monitoring: Inspection of all services performed under this method will be conducted according to a schedule developed by the Government. All services in a Population will be inspected and used for evaluation purposes.

ii. Deductions: Below is an example of deductions taken under this method:

a) Population size is 60

b) Monthly lot contract price for cleaning campsites in a park is $1,200.

c) Sample size is 100% or 60

d) Number of defects is 15

e) Percentage of sample defective is 25% (15 +60 = .25) f) Deduction for the current month is $300 ($1,200 x 0.25)
