The three dominant approaches to ERP implementation are "big bang", location-wise and module-wise implementation.

In the big bang approach the organization decides to implement all relevant modules, for example - Financials, Logistics & HR- all at the same TIME. This has the advantage of getting the full benefit of the integrated software across all functions of the organization. However there is a risk of the implementation getting out of control.

In "Location-wise" implementation, the organization CHOOSES a specific location, say, the head office, one of the new plants etc. The choice could be based on better infrastructure, better IT culture, more co-operative SET of users, higher level of automation etc.

In "module-wise" implementation individual modules are taken up for implementation in a phased manner depending on the criticality of applications. Once again a module taken up for implementation can be implemented across all locations or just one location. Later they can be rolled out to other locations.
