Change management and release management

[maricarbaluyut]

I know the ITIL V2, but sometimes differences between change management and release management are confused.
Also, I am not sure exactly whether release management is necessary.

Could you explain those questions?.

Thanks

"Release Management Process
Objective: To deliver, distribute and track one or more changes into the live environment"
- ISO20000-2:2005

If you do not need to do those things then you do not need release management.

It is a separate question whether you need to establish an organizational unit specifically to carry out this process.

"Change Management
Objective: To ensure all changes are assessed, approved, implemented and reviewed in a controlled manner."
- ISO20000-2:2005

So change management includes ensuring that the release is controlled.

There is a newer version of the ISO20000 standard, but I do not have access to it. Assuming it is not a retrograde step, it will not cloud the issues that are described in the earlier version.

You should also be able to look at the definitions provided in ITIL. If you place them together they should achieve clarity.

When confused about such things always go back to formal definitions and then consider their relevance to your situation.
