~ fe nam:V4 As mentioned above Group Directors have wide authority and responsibility for their Programs, They are familiar with the general technical aims and instrumentation methods of all Projects in their Programs. Through frequent contact with the other Group Directors they are also cognizant of work being done in other Groups, Their primary concern is, however, to ensure that the work being carried on in their Programs is in fact achieving the stated aims of the experiments, By inference a Group Director is in agreement with these aims. Program Directors Each Test Group is divided into several Programs. Program Directors are re- sponsible to the appropriate Group Director and are delegated wide authority ever the work carried out in their Programs. Conflicts between Programs within a single Group are settled in conference with the Group Director. Program Directors are thoroughly familiar with the purposes and methods of all Projects within their Programs and are cognizant of work being done in other Programs, The Program Directors taken together should, and frequently do, form a sort of advisory committee of which the Group Director is chairman, In this capacity they advise the Group Director and assist him in making decisions affecting the over-all work of his Group. Project Officers The basic experimental unit is the Project. Project Officers should be familiar with related work but are primarily concerned with the details of their own experiments. The Project Officer's knowledge ef the purposes and methods of his Project is by implication more thorough than that of any other member of the Test Organization. It is for this reason that the Project Officer is charged with the responsibility of making a detailed statement of the aims of his experiment and the methods he proposes to use, of preparing periodic status reports, of submitting requirements for equipment, construction, logistic support, etc., and of writing the final report on his results. The success of a given test series depends very strongly on the ability of individual Project Officers to understand and carry out the jobs which they have undertaken. The entire Test Organization is devoted to supporting the Project Officers, since these are the men who are going to obtain the basic experimental data desired from a test series. The Test Director's Support Units and Staff Sections have been set up to provide the Project Officers with the help which they will need. Support Units om The Support Units, Rad-Safe, Weather, Assembly, Air, etc. are responsible directly to the Test Director, They provide services which are of general use to all experimental units. General requirements originating with experimental wits are usually passed to the Support Units through the Test Director's Staff Sections or through the Test Director's Office. Details of these requirements are
