Let me ask you: Are your requirements futureproof?
I know it is a tricky question to answer.
How can anyone predict the future? But, we must have a vision for the future.
When you buy a new house to live in, you may not know your exact requirements. However, you may have a vision for the future. For instance, I need a bigger laundry for the growing family and huge storage.
Similarly, we must develop a clear vision for how we like to operate in future. For example, should we centralise/decentralise procurement? Should we consider outsourcing Shared services facilities?
It is vital to understand possible future operating models before investing in any enterprise technology solutions.
Futureproof your requirements by engaging a professional consultant/Business Analyst/Architect. The last thing you want to do is invest millions in automating precisely what you are doing now. The world has moved on! You should too!
