This week ERP implementations Data issues with ERP implementations

A distribution view of systems Because we’re going on our merry way, making decisions, and we don’t realise that the information we are looking at is 2, 3 hours old. And it just causes havoc because people then physically go to do something and they’re like, what drives? The drives, they’re showing on the system, they should be right there! I tell ya, I just went out there, there’s nothing there! Wait a minute!
5
A manufacturing view of distribution The kind of thing that we would sometimes like them to do, would be, to take the product, that mightn’t be the easiest to work on, but if they were to wait one or two days, there might be a product coming through that might be more suitable.

Prioritisation of SIRs (System Investigation Requests) Reports written by end-users (eg. AP Manager) Local IS or global IS now working to gobal requirements Can’t customise the application

How many environments should I have –Test –Production –Development –Training –Business Simulation –… If I implement a change to Production, do I need to implement the same change across all environments? 20 programmers developing / testing new code every day: how do I track releases to production? …
