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. 3, July 2011.

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. 2011).

Basis of Estimating Software Development

Herding Cats

The estimating of software development is both straightforward and complex. When it is suggested that estimating is hard, of no value, and unnecessary, always ask what principle is used to support that claim? Here are some resources that will provide guidance to produce credible software development estimates, in both traditional and agile domains.

Risk Management is How Adults Manage Projects

Herding Cats

In a recent exchange in social media, it was clear the notion of risk and the sources of risk, the consequences or risks and managing in the presence of risk was in very unclear, when it was conjectured , we can simply slice the work into small bits and REDUCE risk. . First, the only risk that can be reduced is the risk created by Epistemic Uncertainty. Making things small does not reduce the risk it may make the uncertainty smaller.

Misunderstanding Making Decisions in the Presence of Uncertainty

Herding Cats

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. The risk is created when we have not accounted for this natural variances in our management plan for the project. Dealing with Aleatory (irreducible) uncertainty and the resulting risk requires we have margin. An aleatory risk is expressed as a relation to a value. Papers on Risk Management.

A project funding policy might require that team submitting detailed estimates should have a confidence of ±5% but what does that really mean? effort, cost) to accompany the qualitative ones, the risk of significant changes being managed in an undisciplined manner increases as does the likelihood of financial and resource capacity erosion to stealth work.

Reading List for the Cone of Uncertainty

The primary purpose of software estimation 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 ? The beginning of all business critical software development projects is the point in time when performing organizations are least certain about the project, yet it is also the time when top management expects to be delivered project estimates that are very precise. 1, January 2011.

In all cases, the assessment of these uncertainties and their impacts on the decision-makers ability to make a risk-informed decision requires estimates to be made. . No risk-informed decision can be made in the presence of uncertainty without estimating. No matter how many times, #NoEstimates claim this can be done, it is simply not possible in any principle-based sense to make a credible decision in the presence of uncertainty without estimating.

Biases in Project Management and How to Remove Them

There is always lots of complaining about the biases introduced into managing projects and making the estimates needed to make project decisions. Optimism bias - a cognitive bias that causes a person to believe that they are at a lesser risk of experiencing a negative event compared to others. The success of a software product, service, and solution depends on good business, financial, and risk management. 2] "The effect of fast and slow decisions on risk taking," M.
