Let’s explore the purpose and use of estimates in the management of software development efforts, and consider possible alternatives.
Why do we estimate and are we making estimates that are actually useful? We say we depend on estimates to make important decisions, and yet we’re often disappointed by the results.
Why are we so challenged at estimation? Are estimates for cost, time, or effort always needed? Is it possible there are other ways to approach our work? If we didn’t estimate, how could we still be successful at making business decisions?
There are a number of things to explore and many questions to ask. For example, do we really need estimates for all the things we are currently using them? Are we getting a reasonable benefit from them? Is it possible to manage software development projects without these estimates, or at least with fewer estimates? Is there a way to prove that estimates are helping us make good decisions?
In this session we’ll participate in some interactive information gathering exercises to see if we can gain a shared idea of our current understanding of the purpose and use of estimates.
We will examine the nature of software development. Our exploration goal is to see if we can work together to come up with some ideas about eliminating or improving on the traditional approaches to using estimates.
