The Nature of the Work Must Determine the Amount of Analysis Practicable. — In determining the amount of time and money required, it is necessary to consider —
1. the cost of the work if done with no special study.
2. how many times the work is likely to be repeated.
3. how many elements that it contains are likely to be similar to elements in work that has already been studied.
4. how many new elements that it contains are likely to be available in subsequent work.
5. the probable cost of the work after it has been studied —
(a) the cost of doing it.
(b) the cost of the investigation.
6. The loss, if any, from delaying the work until after it has been studied.
7. the availability of trained observers and measurers, analysts and synthesists.
