Case Study - Improving Request Cycle Time by over 30% via Lean, saving over 230,000 delay hours per year


A large IT function in a global business was suffering extended timescales when delivering service requests.

1. We gathered process data

To understand the actual times requests were taking to be delivered.

2. We mapped the process, and charted the data

On a Process Behaviour Chart to understand whether the problem was systemic or not, as that determines how a problem is most effectively and efficiently addressed.

4. We continued to measure and act whenever non-systemic problems occured

To ensure the changes were improvements, and were sustained.

5. Result

Service delivery time reduced by 30%, saving over 230,000 delay hours to the customer!
