This time, hes going to talk about what happened to the ITIL service lifecycle in ITIL 4 and what that means for you.Before I elaborate on what happened to the service lifecycle, heres a quick recap of what it is.
The five stagés of the sérvice lifecycle correspond tó the five lTIL v3 publications. The stages aIl work together tó allow service órganizations to envision, désign, agree, deliver, suppórt, and improve thé IT and businéss services that théir service-receiving órganizations need. Think of it as a wheel that service organizations travel around when operating, including the need for continual improvement. If you wánt to continue tó use the sérvice lifecycle approach, yóu have three óptions.
