Which of the following should include in the service level agreement that is an appendix...

When the SLA is a schedule or an appendix to the contract, it should clearly state the following:

1. KPIs: how they are to be measured, who measures them and how often

2. How the measurements convert into scores

3. Any other service level standards, which may be of lesser importance than the KPIs

4. Minimum acceptable standards or scores in each case

5. Range of scores both above and below the minimum acceptable

6. Any mitigating factors which might apply in the event of poor performance

7. Any time period permitted in which to remedy a situation or poor performance.

In this question, "2. Minimum qualification of supplier staffs" and "4. On time service delivery" are the KPIs, while "1. How often the service is measured" is the frequency in which the KPIs are measured.

The remedies available in the event of poor performance should be set out in the body of the contract, along with those for any other contractual breach. These clauses should be cross-referenced in the SLA.
