As the show progresses and events develop, the parties will find that they may need to change their initial expectations and plans to adapt to real events. In doing so, they must amend the terms of their contract so that it reflects the current status of their agreement. This is an inevitable part of the contract, as no one can predict the future with perfect accuracy. However, it is important that the parties do so consciously and openly and with a teamwork attitude so that they remain in agreement on what they are doing. If they don`t communicate, they could end up softening a quarrel about who they really are. If expectations are not clear, roles are foggy, or communication is not effective, your business may not arrive or breach the contract. Much of the clarity on roles is also an in-depth contract management structure. Relevant United Nations staff (programme manager, officer or procurement officer) should analyse the terms of the prospective contract as soon as possible and develop a project structure plan that reflects both the technical and administrative aspects of contract performance. The anquisor and the purchasing manager should agree on interim performance targets on the basis of obligations to perform the contract.
Interim targets will enable the United Nations to measure progress, identify significant variations in performance, take corrective action and take follow-up action. Physical or performance tests provide actual performance data compared to the required performance or physical characteristics or a number of what is considered acceptable by the contract. The requirement to run an engine or operating system at a certain level for a certain period of time is an example of a performance test. Testing materials to determine their chemical composition or density against specification parameters are examples of physical testing. In the case of a bus service contract, waiting at a given bus stop to see if the bus arrives on time is a performance test to verify compliance with the required schedule. Performance testing for labour-intensive services is often carried out in sample form. . . .
