Estimation Excellence Using IFPUG FPA Method

Workshop Motivation 

“Software development costs are significant. And yet for 25 years now, 200% to 300% cost over-runs and up to 100 percent time slippages have been common, frequent, and almost universal. It would seem that software development had no pattern, no process, no methodology, or no characteristic behaviour.”

Workshop Objectives 

After the completion of the course, the participants would be able to:

  • Understand the principles of good estimation
  • Understand the steps involved in a IFPUG Function Point estimation
  • Apply the techniques for IFPUG Function Point estimation
  • Develop metrics for size estimation in the organization

Delivery Method

The course is a mix of case driven, instructor-led, and self paced learning, designed to enable participants learn, experiment and implement the concepts involving application of IFPUG Function Point technique for size estimation.

To enable a thorough hands-on of the concepts taught in the class room, the course is structured around a set of formal case studies.
