Control Chart for Achieving Productivity of 120 Transactions Per Day
Question
A company in the finance sector needs to improve the productivity of employees who process transactions requested by the general public. Complaints had been received from customers because of the excessive time taken to complete the transactions. A backlog had built up but has just been cleared by working every Saturday and an occasional Sunday. The only information available is the average number of transactions processed per employee for each of the last 26 days and the date. The number of employees remained constant. There is no log of any changes on the process, such as employees or supervisors allocated to specific tasks, or any change of method or rules for prioritising the different transactions.
