Summary

Estimating product size, staff effort, project schedule, and cost are inextricably intertwined during the project planning process, which occurs for the first time near the beginning of the project life cycle and many times thereafter, usually at the end of each major phase. Estimating accuracy is often very poor at the beginning of a project, but it improves with project knowledge gained with every phase, culminating in an exact estimate matching the actual size, effort, schedule, and cost (Figure 11-17).
