6 years ago I was called as a contractor by the company I work for as they were desperate that their ERP was just a money drain and despite the money was not functioning at all. Fast forward 6 years. I'm a manager at that company, responsible for business processes and it systems. The ERP works great, everybody's happy. Secret recipe: dismantle custom company processes. Culture change: realize that company's not that special and don't need special ERP recipes. Takeaway: if the ERP standard is set up in a certain way, probably there's a very good reason underneath that setup.
