Have faith in your process

It is vitally important to maintain robust Business Modeling and Requirements Engineering processes in your organization.

Why ? well Donald Rumsfeld said it best -

"There are known knowns; there are things we know we know.

We also know there are known unknowns; that is to say we know there are some things we do not know.

But there are also unknown unknowns – the ones we don't know we don't know."

With a trustworthy and proven process, you can be confident that you will uncover the known unknowns, and possibly bring to light some unknown unknowns into the discourse...

Recommended reading for your Requirements Practice

A number of books that I use and recommend each project team to have available:

•  D. Leffingwell, et al. (2003), Managing Software Requirements: A Use Case Approach (2nd Edition), Addison Wesley
• A. Cockburn (2000), Writing Effective Use Cases, Addison Wesley
• K. Wiegers (2003), Software Requirements, Microsoft Press

There are also other books mentioned in older posts below.

RE = RM + RD

Requirements Engineering = Requirements Management + Requirements Development
