Managing Change: Business Challenges

We have to get more with less

Our customer’s business model is changing

No one can tell me when we’ll finish rolling out

Three different customer systems and more on the way

This merger will make us more competitive

How do we meet these new regulations It’s too hard to

get the information we need

The problem with unmanaged changeSlow releases, poor quality, no predictability

Poor release integrityFiles get lost and cause recurring problems

Quality depends on error prone, redundant tasksManual examination of buildsManual mapping of files to tasksManual merging of changesManual activity reporting

Lack of communicationWhat to work on?What’s important?

Difficult to determine project statusNo connection between activities and assets
