ALL THOUGHTS AND IDEAS WELCOME!

I’M TRYING TO EVALUATE WHICH WOULD BE MORE SUITABLE FOR A PROJECT I’M IMPLEMENTING. IT INVOLVES CORE FINANCIALS AND DISCRETE MANUFACTURING MODULES. WE ARE NOT CERTAIN WHICH WOULD BE MORE SUITABLE BIG BANG APPROACH WHEREBY ALL MODULES GO LIVE AT ONCE OR PHASE BY PHASE, WITH FINANCIALS FIRST AND MANUFACTURING MODULES TO FOLLOW OR PHASE BY PHASE WHERE THEIR HQ GOES LIVE FIRST AND OTHER OFFICES GO LIVE NEXT WITH ALL THE MODULES.

ANY SUGGESTIONS GREATLY APPRECIATED!

These are all the deciding criteria to opt a good rollout strategy for an Implementation Project.

BIG BANG APPROACH
————————————-
1. Project Implementation Cost (Huge Cost Involved)
2. Require more human resource
3. Choosen by Large Organizations.
4. More Efficient (Do not have to create temporary interfaces)
5. Implementation phases of the modules must be kept synchronized.
6. Implementation time will be more.

PHASED APROACH
——————————-

1. Project involves less cost compared to BIG BANG.
2. Require less resource since the rollout is phase by phase.
3. Less Time
4. Choosen by small companies.
5. Requires the use of temporary automatic or manual interfaces to act as bridges between the oracle apps and your existing legacy systems before all the modules are in production.
6. Consider the future modules rollout & required setup’s. (Example: Multi-Org, setup & so on)
