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.

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?

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.
