Activity-based software estimation using work break down structure

Abstract

Software Cost estimation at activity level is very much accurate than macro estimation with respect to phases of software development life cycle, but the same is very difficult to achieve[1]. Activity based estimation focus on key activities should not be left out and if any effort variance occurs it will be possible to track at particular activity level rather than affecting the entire activities[1]. Activity-based Software estimation based on work break down structure has been explained by collecting and analyzing the data for 12 Enhancements from Application service Maintenance project which were already delivered. This paper explains how to arrive accurate estimation at different micro level activities of Software Development Life Cycle(SDLC). © 2007 Springer.
