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.

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.

Risk is everywhere on projects. This risk comes from two types of uncertainty. The idea of risk and its management and handling is a critical success factor for all software development. Peter Drucker (1975) Management (From The Principles of Software Engineering , Chapter 6, Tom Glib, 1988). .

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 ? This variation can be explained by the fact that initial concepts do not describe the final software system accurate enough.

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. Uncertainty is related to three aspects of the management of projects: The external world - the activities of the project itself. First, let's establish a principle.

This is the foundation for estimates. These estimates are critical to both developers and customers.
