11.0 Quality Control.

The contractor shall establish and maintain a complete quality control program for the performance requirements of this contract. The Contracting Officer’s Representative will evaluate the contractor’s performance based on the PWS.

12.0 Quality Assurance Surveillance Plan.

12.1 Purpose. This Quality Assurance Surveillance Plan (QASP) has been developed to provide the standard of surveillance for base telephone services for the TISD, Marine Corps Air Station, Cherry Point, N.C. The Contracting Officer (KO) will appoint an individual at the time of award as the COR. COR Contact information is also provided in the award. The COR will also serve as the Quality Assurance Evaluator (QAE) and will use this QASP to ensure the standards of the contract are being met. The COR/QAE will be referred to as the COR throughout this QASP.

12.2 Performance Standards. The QASP provides a systematic method to evaluate the service the Contractor is required to furnish. The COR will assess the Contractor’s performance to ensure the Contractor is performing up to the specified standards. The standards for this Performance Work Statement (PWS) are stated in the Level of Effort Requirements Summary (PRS) included in this QASP. The standards for this procurement are metric-driven.

12.3 Management and Oversight. The QASP is based on the premise that the Contractor, and not the Government, is responsible for the management and any Quality Control action required to meet the terms of the contract. The performance requirements recognize that the Contractor is not a perfect manager and that unforeseen requirements and uncontrollable problems do occur. Good management and use of an adequate Quality Control Plan will allow the Contractor to operate within specific performance requirements. QASPs are designed to be objective, fair, and consistent in evaluating Contractor performance against the provided standards.

12.4 Acceptable Quality Levels (AQLs). AQLs have been established in the PRS and provide performance standards that the Contractor will meet in performing the contract. In the event the Contractor does not meet the established AQLs, the KO has the right to exercise the negative incentives stated in this QASP.

12.5 Methods of Surveillance/Evaluation. The COR will evaluate the contractor’s performance using one or more of the following surveillance methods:

a. 100% Inspection: Inspection where specified characteristics of performance are examined and tested to determine conformance with defined requirements in the Performance Work Statement (PWS).

b. Random Inspection: Sampling method in which each unit of the population has an equal chance of being selected.

c. Customer Surveys and Feedback: A review method where customers and end users are surveyed to provide input on specific service levels.

12.6 Negative Incentives. If any of the performance requirements do not meet the AQL set in the PRS table, the COR shall document the discrepancy(s) and shall notify the Contractor promptly, and the KO, on a monthly basis, for appropriate action. When the performance is below the AQL standard, the Government may implement negative incentives that include: increased surveillance, reduction in contract price, and/or decision not to exercise next option.

12.7 Notification. The COR will notify the KO, in writing, of unacceptable quality levels. The COR will promptly provide written notification of discrepancies on a monthly basis, or immediately if the situation significantly affects the well-being of the project. The Contractor will be given the opportunity to respond, in writing, to each discrepancy.

12.8 Response. The Contractor shall provide a written response to the cause and the corrective action to prevent recurrence within ten (10) working days after receipt of the KO’s notification. The Contractor should cite specific quality assurance program procedures or new procedures instituted to prevent recurrence.

12.9 Ratings. The following criteria will be used for performance evaluations: Exceptional, Satisfactory, Marginal, or Unsatisfactory. Upward or downward arrows may be used to indicate an improving or worsening trend insufficient to change to the assessment status.

a. Exceptional. Indicates performance clearly exceeds contractual requirements. The area of evaluation may contain a few minor problems for which corrective action appears highly effective.

b. Satisfactory. Indicates performance clearly meets contractual requirements. The area of evaluation contains some minor problems for which the corrective actions appear satisfactory.

c. Marginal. Indicates performance meets contractual requirements. The area of evaluation contains one or more serious problems for which corrective actions have not yet been identified, appear only marginally effective, or have not been fully implemented.

d. Unsatisfactory. Indicates the contractor is in danger of not being able to satisfy contractual requirements and recovery is not likely in a timely manner. The area of evaluation contains one or more serious problems for which the corrective actions appear ineffective.

12.10 Documentation. Documentation used and referenced to perform surveillance will consist of monthly reports, contractor plans and procedures, schedules, customer feedback and contract data requirements.

a. Recording Observations. The COR shall use Surveillance Logs to record information on scheduled observations and deficiencies noted. Each observation is recorded on the log. The documents then become a formal record for reference. The contractor is to be told each time that a deficiency is found during scheduled observations. The COR makes a notation on the Surveillance Log of the date and time the deficiency was discovered, then, the COR asks a contractor site manager to initial the notation, documenting notification of the deficiency only.

b. Potential Unacceptable Performance. The COR must identify the specific service that is unacceptable and the possible causes, and ask a number of questions which, if answered, will probably pinpoint the source of the problem.

c. Documenting Unacceptable Performance. The COR must attempt to resolve the problem with the contractor. The original log and the attempted solution (along with an evaluation of results) are forwarded to the Contracting Officer through the COR. Based on the severity of the discrepancy and the success of the solution, the COR will notify the KO. The contractor shall complete a response to the unacceptable evaluation if requested by the KO or by its own choice.

12.11 Taking Action.

a. The COR may evaluate the contractor’s performance and document any non-compliance, but only the KO may take action against the contractor for an unacceptable rating.

b. When the contractor’s performance is unacceptable and a formal action is indicated; the COR will determine what action is appropriate for the specific circumstances and make a recommendation to the KO.

12.12 Documentation. The COR retains a copy of all inspection schedules and surveillance activity logs during the course of the contract and forwards them for inclusion in the contract file at the end of the surveillance period.

However, when a specific service becomes unsatisfactory during a surveillance period, the inspection documentation supporting the contract discrepancy report is forwarded to the KO.

13.0 Performance Standards (Metrics).

The contractor shall provide operational SIP trunks with an uptime of 99.99% based yearly.

Upon notification by TISD personnel, the contractor shall restore services in a mean-time of 4 hours or less.

The contractor shall provide deliverables in accordance with schedule.
