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.

DDSTOP The Saga Continues

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 ). Yet another class #NoEstimates lack of understanding of estimating, reference class forecasting, reference class databases, parametric estimating, estimating tools, and other well established estimating processes in the agile software development world.

DDSTOP The Saga Continues

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. With what appears to be NO understanding of how to estimate, this author ignores the processes used in developing products or services in the presence of uncertainty. Define the probabilistic ranges of the work in a single point estimate manner. All by NOT Estimating?

Ranking the Most (and Least) Productive Industries

Redbooth

As the data above shows, company size plays a sizable role in productivity, but what other factors influence how quickly work gets done at a company? Industries producing complicated physical goods like Aerospace & Defense and Technology Hardware, also take a long time for work to be completed. To conclude, we present all the data on how long it takes for task completion in each industry where we have sufficient data to provide a productivity estimate.

9 Inspirational Teamwork Examples

Their music is the soundtrack of an era and continues to influence musicians to this day. 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. It seems that people have been spelling team with an “i” for a long time. We live in a culture that promotes the roughed individual, the self-made person, the entrepreneur.

The Impact of Technology on Project Management: Pre-1950s to the Modern Age

Keyedin

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. Focus during this time was on the internet and the influence it had on how businesses carried out their work.
