An empirical study of modifying the Fagan inspection process and the resulting main effects and interaction effects among defects found, effort required, rate of preparation and inspection, number of team members and product 1st pass quality

We present findings from a six sigma black belt project. Every black belt project has a charter that defines the customer focus and the goals of the project. This project is designed to identify the key factors that impact effectiveness for software inspections and to compare Fagan inspections and modified Fagan inspections used at Motorola. Empirical data is collected and simulation models of the generic processes are created. The models that are created abstract away unnecessary details of the process and provide a test-bed to evaluate the methodologies relative to their effectiveness, cost in effort, time required (duration), and complexity of the activity.
