- The manager at an IT Consulting provides IT support to a number of clients. The manager is particularly concerned about a major client that is under Service Level Agreement (SLA). Under this SLA, all tier one issues called in must be resolved within 12 hours. There is a $150 penalty for every call that exceeds the SLA time. The manager has the following information from collecting and analyzing call data on tier one issues for this client for the past 6 months.
Average number of calls per day = 30
The mean time for resolving issues = 10 hours
The standard deviation of the resolution time = 1.1 hours
- What % of calls will exceed the 12 hours SLA requirement?
- Is the call center process capable?
- What is the expected penalty cost per year if any?
