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?

There is a discussion of the conjecture that estimates are a waste, estimates can't be done, estimates are evil, estimates must be stopped immediately. In our domain of engineered systems, there is a broad range of problems, complex issues, approaches to solving problems. In all cases, we start our work with.

In the estimating business, like many things in project management, there is confusion about principles, practices, and processes. A good estimation approach should provide estimates that are within 25% of the actual results, 75% of the time. Software Engineering Metrics and Models. Dunsmore and V.Y.

Since all risk comes from uncertainty - reducible (Epistemic) and irreducible (Aleatory), estimating is a foundation of all we do. There is no discussion of the conjecture that estimates are a waste, estimates can't be done, estimates are evil, estimates must be stopped immediately. illities are a waste.

. - Peter Drucker (1975) Management (From The Principles of Software Engineering , Chapter 6, Tom Glib, 1988). In order to make risk-informed decisions, we must estimate the outcomes and the impacts of those outcomes on future activities (cost, schedule, and technical performance of products and services).

There's a recent post titled Four Fallacious Reasons to Estimate. It lists the usual suspects for why those spending the money think they don't have to estimate how much they plan to spend when they'll be done producing the value they've been assigned to produce for that expenditure. Let's look at each one in more detail.

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 ? 10 Deadly Sins of Software Estimation , Steve McConnell , Construx, 2002. Steve McConnell.
