Today there are numerous books on ITSM, but none which tells how to implement and improve ITSM practices for organizations and how to bring effectiveness in ITSM operations. Hence, I have chosen to write books in this area, providing detailed information; and this book "Guidance for Problem Management" is part of a series with explicit focus on problem management. And the focus is on topics like implementing problem management through Six Sigma's DMADV approach, improving problem management through Six Sigma's DMAIC approach, Roles and responsibilities in Problem management, Essentials for problem management operations, Integrations in problem management with other processes and functions, Best practices for problem management, Best practices for RCA, Problem management in DEVOPS and SCRUM, Advice for PM operations and many more interesting topics.
