Course Overview

Your Estimate is Right — the Problem is Reality!

"How long will it take you?" is one of the scariest questions that business analysts have to answer. Decision makers pose this question before you know what you are going to have to do to analyze the requirements, meaning you have not yet done the analysis upon which to base your answer. Given that uncertainty, it is no wonder that whatever answer you come up with will be off, leading to a missed delivery date and unhappy customers.

This workshop introduces methods that improve early estimates and the communication of the factors that affect them. We cover foundation approaches for state-of-the-practice in early project estimating based on business and stakeholder requirements, story points, and other relevant techniques. We discuss factors that affect estimating accuracy and you apply them in a case study. Included in the class materials is an individual, time-limited license for our estimating tool, Quest For Better Estimates®.
