Change Management

In many job roles an element of change and change management is involved.  This has definitely been true for me in my previous two roles and in my current role.  I'm interested in change and how it affects people and processes.  I've had quite a lot of experience of change especially managing new teams and either setting up new teams to manage a project or bringing together teams to provide a service.  It is always challenging and that is what makes it interesting and ultimately rewarding if you can get it right.  I'm very conscious of trying to make the change right for the people involved as well as the purpose / goal / business need of the organisation.
Although I have read some background information and theory about change management, I think I should develop my knowledge in this area more.  I sometimes depend on my experience to manage particular situations and although this works, I want to make sure that I'm being as effective as possible.
A couple of weeks ago I went to talk to a member of staff in the Organisational Development section of the university.  We talked about change and about some of the factors that I'm managing at the moment.  She suggested looking at some change models as a starting point - images below.  At least they will give me something to think about while exploring other approaches and I found it helpful to have an objective discussion and reflect on the situation.
