Typical Resources Deployment

All phases do not work under uniform manpower-loading; naturally, Phase 1 starts with light manpower during the conceptual study and reaches peak manpower (100%) at Phase 3; it decreases again when flight testing starts, by which stage the design work is virtually done and support work continues. Figure 2.2a is a typical distribution of cost and manpower loading (an average percentage is shown); the manpower-loading forecast must be finalized during the Phase 1 study. Figure 2.2b shows the cumulative deployment. At the end of a project, it is expected that the actual figure should be close to the projected figure. Project costs consist primarily of salaries (most of the cost), bought-out items, and relatively smaller miscellaneous amounts (e. g., advertising, travel, and logistics). Chain lines in Figure 2.2 illustrate the cost-frame outlay.
