Which software development methodology is right for you?

Over the past few months, I have interacted with many IT leaders in various agile forums. Irrespective of the process maturity in their respective organizations, I have always seen a pattern in all such discussions, which invariably leads to the question "What software development methodology is right for me?"

If we have interacted, you would know my response already...

To me, this is NOT the most important question you should be asking. Before you call any agile consultant, Kanban specialist or a RUP expert (?!$!), I would recommend you find answers to the following questions

1. What are my business objectives?
2. Does my current software development methodology encourage behavior aligned to my business objectives?
3. If not, can it (existing software development methodology) be optimized to align with my business objectives?
4. If yes, Which practices from other software development methodologies can integrated with my existing methodology?

If not, (Must you change to a new software development methodology)

• Which behavioral changes you would like to see in your work force?
• Which software development methodologies encourage such behavior?

Any software development methodology should be looked as a means to an end (achieving your business goals). In my experience, the the most common mistakes IT leaders do, it to incorrectly assume that adoption of a new software methodology is the end in itself. That is a recipe for disaster.
