CHAPTER 3<br />

ITIL Service Lifecycle<br />

The ITIL service management framework we have today was not born overnight. It has<br />

evolved through years of trials, errors, and endurances. Service organizations learned<br />

the art of IT service management through trial and error. The practices that worked were<br />

continued forward, and these successful practices and activities laid the <strong>foundation</strong> for<br />

the ITIL as we know it today.<br />

My first experience of ITIL was the second version of ITIL, two versions previous to<br />

the current version. When I picked it up (ITIL v2) and read through it, cover to cover, I was<br />

amazed at how all the aspects of service management were brought forth and shaped. So<br />

when ITIL v3 was introduced, a reporter who had insight into the changes described ITIL<br />

v3 as a paradigm shift and strategically different. And my first taste of ITIL v3 just blew my<br />

socks away!<br />

While ITIL v2 introduced two silos—service delivery and service support—to carry<br />

out various service management activities, ITIL v3 spun a story in the service management<br />

world that brought about the idea of creating an IT service, progressing onward to further<br />

developmental and deployment stages of IT services. The IT service story in ITIL v3 is a<br />

good one. Its flow and logic make it rugged, flexible, and adaptable to IT service provider<br />

organizations.<br />

In this chapter, I will introduce the lifecycle of IT services and how a service can be<br />

incepted, designed, built, tested, and transitioned into operations. The story does not end<br />

here; - it adopts Deming’s quality principles (discussed in chapter 8 - Continual Service<br />

Improvement) to provide momentum and mature over time.<br />

3.1 ITIL Service Lifecycle<br />

ITIL v3 (ITIL henceforth) was derived from various high-level activities that encounter an<br />

IT service, and each of these high-level activities were introduced as phases in the ITIL<br />

service lifecycle. The five phases are:<br />

1. Service strategy<br />

2. Service design<br />

3. Service transition<br />

4. Service operations<br />

5. Continual service improvement<br />
