Forum Moderators: phranque
When I started my IT career, the organisations I worked with didn't really do formal change management. And that wasn't really a problem: either they were small enough for it not to matter (we just told the handful of users: “We're about to upgrade X”), or the departments I worked in were sufficiently small and autonomous that the same logic applied as above.
Over the years, though, it's become clear that formalising the change process isn't just useful: it's an absolute necessity. Not only that, but you absolutely need it in both the development and operational fields – and for different reasons.
