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. December 2010.

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. Johnson, STC 2010.

Microeconomics and Risk Management in Decision Making for Software Development

Herding Cats

When we hear about software development disasters and then hear that estimates are to blame, and NOT Estimating will somehow reduce or prevent these disasters, think again. ISO 31000:2009, ISO 17666:2016, and ISO 11231:2010 Risk is Uncertainty that Matters. Each of the categories operates in the presence of uncertainty and requires that estimates be made about the probability, conseqeunce of the resutling risk.

Why Johnny Can't Do The Math

Herding Cats

In a previous post, Why Johnny Can't Estimate , mentioned some resources for estimating, the principles of business and technical management that demand estimates be made to make decisions, and background on the sources of uncertainty, that create risk, that require estimating to increase the probability of project success. One of the #Noestimates advocates has now discovered a phrase: Estimates are non-ergodic. It is not the Estimates that are non-ergodic.

The project scope was changed by the owner, or the management, or you had unfortunate estimates of the time, and resources that would be required to complete particular steps in the schedule. John Owen: First, let’s talk about the estimates that we’re using in our schedule.

How to Use nTask for Waterfall Project Management – A Practical Guide for First Timers

We did an extensive analysis of various factors that influence waterfall project management. The United States government settled on the Waterfall Model as the model’s advantages perfectly fulfilled their requirements. The federal government insisted on engineering rigor and a superior quality product while maintaining great control over the final product. Cost estimation. Easy to estimate.
