His September column “Agile on a Fixed Budget” is now posted here.
From Scott Ambler:
The article was originally motivated by the “How do I do Agile on a fixed price/estimate project” questions that I invariably get when working with clients or internal development teams. So I decided to take it one step further and address the question “How do I do Agile when one or more of the cost, schedule, or scope is fixed up front?”
The column first summarizes strategies for what you would do when each of these factors is allowed to vary so that you understand what trade-offs you’re making.
Then it describes what I consider to be your best approach remaining to you for each combination of constraining the three factors.
The main point of the article is that although it isn’t ideal to have one or more of these factors constrained, you can still take an Agile approach even when such constraints exist.
Hope it is helpful for you!
