The Problems with Schedules

Herding Cats

The Core Problem with Project Success. Unrealistic Cost and Schedule estimates based on inadequate risk adjusted growth models. Before diving into the details of these, let me address another issue that has come up around project success and estimates. There is a common chart used to show poor performance of projects that compares Ideal project performance with the Actual project performance. Don't know these, you've doomed the project on day one.

DDSTOP The Saga Continues

Herding Cats

There's been a rash of conjectures about all kinds of bad business, project, and software development (agile and traditional) management ideas of late. We were one of the first users of eXtreme Programming, long before Scrum was around and presented that early work in 2003, " Making Agile Development Work in a Government Contracting Environment, Measuring velocity with Earned Value." . This means defined the Most Likely value for the range of duration or cost for the item.

We were one of the first users of eXtreme Programming, long before Scrum was around and presented that early work in 2003, " Making Agile Development Work in a Government Contracting Environment, Measuring velocity with Earned Value." . For cost and schedule, there are databases containing 1,000's of past projects.

Estimating is a Learned Skill

Estimating is a learned skill, used for any purpose from every-day life to management of projects. 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. .

Information about key project cost, (technical) performance, and schedule attributes is often uncertain or unknown until late in the program.
