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. Here's some materials that provide the tools and processes needed to learn how to estimate.

Increasing the Probability of Program Success

We're working on a White Paper for the Joint Space Cost Council which is an organization composed of government (NRO, NASA, USAF, and others) and industry representatives with an interest in space. The origins of this paper came about at a recent JSCC meeting here in Boulder, with local Aerospace contractors, the DCMA (Defense Contract Management Agency) and several government agencies (NRO and NASA). Unrealistic Cost and Schedule Estimates. Estimating Processes.

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." . 40 - Estimation is a Problematic Practice of Companies Doing Dangerous Things. A #Noestimates advocate makes the claim that having a ±10% accuracy for estimates of cost and duration is a dangerous thing. link] Cost Estimating Tools.

DDSTOP The Saga Continues

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." . In our domain of aerospace and defense, we have reference class for cost, schedule, architecture (DODAF), risk and other attributes of every system ever built in the DOD ( CAPE , CADE ) and NASA ( CARDe/Once ). link] Cost Estimating Tools.

The Problems with Schedules

Herding Cats

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. All that line says is this was the baseline estimate at Completion for the project work. It says nothing about the credibility of that estimate, the possibility that one or all of the Root Causes above are in play. Just the estimate.

9 Inspirational Teamwork Examples

According to NASA, there were an estimated 400,000 people involved in making the moon landing possible. This included teams of scientists, engineers and technicians, many who had not worked in aerospace before. There was no central government and the risk of the new nation falling apart was even more of a concern than it is today! It seems that people have been spelling team with an “i” for a long time.

Notable projects of this time period include the construction of the Hoover Dam from 1931 to 1936, which included the employment of an estimated 5,000 workers, and the Manhattan Project, which was a research and development project that produced the first atomic bombs during World War II and involved 125,000 workers, cost nearly $2 billion. Project management (PM) dates back as far as there has been a need to achieve things.
