Software Estimating Resources

Herding Cats

This blog page is dedicated to the resources used to estimate software-intensive systems using traditional and agile development methods. The reason for this resource page is the lack of understanding of how to estimate, the urban myths about software estimating, and the fallacies that estimating is not needed, when developing software, in the presence of uncertainty, when spending other peoples money. Estimating Probable System Cost,” Stephen A.

Estimating is a Learned Skill

Herding Cats

Estimating is a learned skill, used for any purpose from every-day life to management of projects. When I left for the airport this morning to catch my flight to a customer site I estimated, given the conditions, how much time I need to get to my favorite parking spot at DIA. The same process for estimating is applied to multi-billion dollar projects we work. And the same process is applied to the Scrum development processes on those projects. . 2011).

Misunderstanding Making Decisions in the Presence of Uncertainty

Herding Cats

What happens if you shift focus from "accurate estimation" to "reliably shipping by a date"? . All project work has uncertainty. Uncertainty comes from the lack of precision and accuracy about the possible values of a measurement of a project attribute. If your project has no uncertainty, there is no need to estimate. Turns out in the real world there is no such project. Our knowledge of this world - the planned and actual behaviors of the project.

Microeconomics and Risk Management in Decision Making for Software Development

Herding Cats

The primary economic driver of the life-cycle structure is the significantly increasing cost of making a software change or fixing a software problem, as a function of the phase in which the change or fix is made. By the way, the pure conjecture that agile enables late changing requirements to not have a significant impact on the cost and schedule of the development project is completely lacking any testable evidence outside of personal anecdotes of agile advocates.
