Killing of incident through lean IT
The CIO of a large company wishes to improve the response time from one of his maintenance teams and reduce the volume of incoming tickets. His objective is to free time so the team can tackle more value-added activities such as application evolutions and new projects. The team is responsible for maintaining applications of core processes, so it was critical to be more responsive. Project duration: 13 weeks.
The project was led by 1 Operae coach, supporting 1 change agent. The operational team included 1 team leader and a technical staff of 7.

Volume of incidents:

- creation of a new incident classification standard shared with all support teams and business analysts
Volume of support requests:
- “go and see” at the user site to understand the difficulties encountered
- red bin analysis to identify recurrent requests
- implementation of permanent fixes in the information systems concerned
