I wrote in a previous introductory ITIL 4 blog post that there was no mention of the ITIL Version 3 Lifecycle in the new version, and expressed hope that it might make its way into the intermediate materials.
Of course, upon a bit of further reflection, I have come to see the underlying Lifecyle concept is front and center – it’s just now called the ‘Service Value Chain (SVC)’ and it is clearly embedded as the keystone of the Service Value System (SVS).
I get why this was done – and once you get used to abandoning stuff you are familiar with, it makes a lot of sense.
The SVS is explicitly NOT a linear concept- there can be iterations and interactions and feedback throughout the system and between the parts of the Value Chain
- Of course, this was true of the Lifecycle as well- but that’s not how it was necessarily taught and interpreted and applied.
- The Service Value Chain makes this more clear now.
The Service Value Chain is a modular design. In other words there is NOT just ONE ‘Service Value Chain’ – it is expected that an organization would have several, or more.
- Again – this was true of the Lifecycle as well… but… the whole modular concept is more explicitly central to the SVC.
The Processes – er.. Practices – have been decoupled from the stages of the Lifecycle — er.. Service Value Chain.
- This helps enforce the non-linearity of the system. For example, Change Management (er… Change Control) was never intended to apply to ONLY Service Transition. But, since it was covered in that volume that was a frequent misinterpretation. Now, it is not associated with any specific phase of the Lifecycle/Service Value Chain.
- To emphasize — this is much closer to the reality of how this should all work in practice.
So I understand why the term ‘Lifecycle’ has not appeared (so far) in the ITIL 4 materials. It helps to emphasize the nonlinear, interconnected nature of the overall management system defined by the framework.
And – really – you don’t have to work too hard to link the parts of the Service Value Chain concepts back to the ol’ LifeCycle. And- we’re going to have to do this, at least for a while, because – as I keep saying- we are still waiting on the intermediate guidance. So- don’t throw out your old V3 books just yet (or ever!)
