Why our brain is not built for softwareengineering. Knowledge work’ refers to tasks that take place mostly in our minds, like predicting scope, setting up plannings, considering consequences of changes to complex systems, working out test cases and estimating complexity. This will affect all estimates and predictions.
The primary purpose of softwareestimation is not to predict a project’s outcome; it is to determine whether a project’s targets are realistic enough to allow the project to be controlled to meet them ? 10 Deadly Sins of SoftwareEstimation , Steve McConnell , Construx, 2002. Steve McConnell.
What happens if you shift focus from "accurate estimation" to "reliably shipping by a date"? . If your project has no uncertainty, there is no need to estimate. All estimates have precision and accuracy. Deciding how much precision and accuracy is needed for a credible estimate is critical to the success of that decision.
Victorine Ghobeira , a Senior Business Analyst and Project Manager at Dataquest, says that “preventing a lack of resource starts when defining and estimating activities and leads to creating a realistic schedule. Facts and Fallacies of SoftwareEngineering by Robert L.
Estimation locks down choices early through upfront t decision making, #NoEstimates preserves options. This is the same paradigm of Agile software development where responding to change over following the plan is part of the original manifesto. Aligning Software Investment Decisions with the Markets ," Hakan Erdogmus. "
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. So when you hear we can't estimate you'll know better.

So here are some books, handbooks, and guides that sit on my shelf that are used pretty much all the time on the Software Intensive System of Systems we work on. But when some statement is made about risk, estimating, performance modeling, or the like - always ask for references. I'm not expecting anyone to read all these books.
They asked a software developer what it would take, and he estimated something like 20,000 pounds over several months. You probably remember the case of the Volkswagen softwareengineer who was sentenced to prison for writing code that enabled vehicles to pass emissions tests fraudulently.
