POM-XOMO Software Engineering Models

XOMO combines four software process models from Boehm’s group at the University of Southern California. XOMO derives four objective scores: (1) project risk; (2) development effort; (3) predicted defects; (4) total months of development (Months = effort / #workers). Effort and defects are predicted from mathematical models derived from data collected from hundreds of commercial and Defense Department projects.

POM3: According to Turner and Boehm, agile managers struggle to balance idle rates, completion rates, and overall cost. • In the agile world, projects terminate after achieving a completion rate of (X < 100)% of its required tasks. • Team members become idle if forced to wait for a yet-tobe-finished task from other teams. • To lower idle rate and increase completion rate, management can hire staff–but this increases overall cost.
