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.

ISO 31000:2009, ISO 17666:2016 and ISO 11231:2010 Risk is Uncertainty that Matters.

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.

Simplifying Schedule Risk Analysis Using Microsoft Project Custom Fields – Transcription

MPUG

Unfortunately, many projects to the detriment of the people executing them, are delivered late and it’s not usually anything to do with estimating or project execution. It’s got nothing to do with poor estimating, poor execution or even risks that occurred or did not occur. You don’t have to go to a lot of effort to force your estimators to give you three point estimates in terms of durations for all the tasks in the schedule. Can we re estimate it?

We did an extensive analysis of various factors that influence waterfall project management. A 2010 report by National Research Council emphasized how many of the terminology used to describe the engineering and manufacturing development phases focus on elements of Waterfall Model like preliminary design reviews and critical design reviews.

And so if something has never been done before, it’s hard to kind of figure out an estimate. And that way instead of spending a lot more time on requirements, what I can do is go, “All right, we’re going to time box these, we’ll make sure we have our estimates in place, but inherently I can quickly validate the requirements with something that’s much more visual.”
