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. Define the probabilistic ranges of the work in a single point estimate manner. There are databases for Function Points .
Let's start with a clear and concise description of the problem of successfully managing projects in the presence of uncertainty: Accurate software cost and schedule estimations are essential for non-trivial software projects. As a software project progresses, more information about the project is known.
In all engineering worlds, from softwareengineering to bending metal for money, there is really nothing new under the sun. Rarely are softwareengineers working on science experiments. For software development starts with. maybe a read of the resources of Estimating Agile Software Development may help.
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.
