Should PLM Fit Business Process or Change it?

If company business processes need to be re-engineered it’s a management decision. Now the question is if we would like to make this decision part of the process for software purchase? I see two opposite approaches: 1/implementation of the best practice system which will require changes and, as a result, improvements of company’s business process; 2/Adaptation to existing processes with the future capability to improve and optimize. There are some pros and cons in both directions:

Implementation of the system best practices: Pros – better process engineering, optimization, ability to bring existing best practices. Cons’ – changes of business processes and need for management decisions potentially will cause implementation to be delayed and increase chances of failure.

Adaptation to existing processes: – Pros – potentially shorter implementation cycle, fewer organizational changes; Cons’ – tendency to automate obsolete and non-efficient processes.
