First Wealth Bank outsourced its customer interactive services operations to Customer Calling Services (CCS) about 5 years ago. First Wealth Bank guaranteed a minimum volume of 300,000 calls per year at a rate of $4.50 USD. Over the last two years, the service performance of CCS has deteriorated to such an extent that First Wealth Bank is considering canceling the contract. CCS has been collecting data on the duration of the representatives` availability to answer the calls and the hold time. The data for the last few months is shown in Table 1. The performance measures that were of interest to First Wealth Bank were:
Read the case study and then answer the following questions.
Exercise 1- Process capability indices
Using the data given in Table 1, determine the process capability indices for the performance metrics. Based on the available data, provide the appropriate interpretation for the process capability indices.
A. ‘First Call Resolution’. The specification limits for the FCR are LSL = 75% and USL = 100%.
B. ‘5 Day Resolution’. The specification limits for the 5DR are LSL = 90% and USL = 100%.
A. What kind of data is shown in Table 2? Which method would you use for measurement system analysis (MSA) to verify the repeatability and reproducibility of QA results? Conduct the appropriate MSA.
B. Determine the potential causes of why CCS fails to meet First Call Resolution targets consistently.
C. Brainstorm and propose solutions for the elimination of causes of failure to meet FCR targets.
Exercise 3- FMEA
Identify potential failure modes and their effects for the solutions proposed in Exercise 2 using learning on FMEA.
