Analysis Techniques For Man-Machine Systems Design

NATO UNCLAS SIFIEDAC8243(Pane1-8)TR17- 66 -Volume I136. There is a need to develop handbooks for both management and specialists. Themanagement handbooks need to clearly and simply address usage criteria such as when thetechnique should be employed as well as cost and value comparisons, i.e., what the programmemanager needs, based on the NATO-agreed life cycle phases used in this report. Sawyer et. al(1981) provide some guidance on the contents of a manager's handbook. The specialisthandbooks should give technical descriptions of the specific processes and technical valuecomparisons between them. Such information is included in Volume 2 of this report and U.S.DoD-HDBK-763. Those documents provide the basis for NATO handbook development.5.4.3 An approach for computer based system development137. Within the context of the development of CAD, MANPRINT-IDEA, and theCALS systems, NATO agencies should consider the development and application of computersoftware to facilitate the application of a standard approach to human engineering analvsis andto provide computer-aided guidance to project managers and system developers.5.4.4 Approach summary138. The steps recommended in this developmental process are to:(1) Review and combine the information in the existing NATO and nationalspecifications into a NATO standard which lists and describes the generictechniques.(2) Develop a NATO programme manager-oriented guide or handbook which coverstechnique and employment characteristics, with particularly emphasis on phases ofapplication and cost-benefit parameters.(3) Develop a NATO technical human engineering analyst-oriented handbook whichnot only identifies and clarifies analytical techniques but also describes them indetail.(4) Study the development of computer based standards, specifications and guidelinesto facilitate the application of human engineering in NATO projects.5.5 CONCLUSIONS139. From the review of national and NATO standards, specifications and guidescovering human engineering issues, the following conclusions are drawn:1) There are few requirements documents which govern human engineeringanalytical techniques: most are design criteria specifications.2) Of the few national or NATO specifications that cover analytical techniques, mostonly identify or list the technique and do not provide additional employment ortechnical information.3) Existing handbooks and guides are not tailored to specific users of theinformation, and none cover information required by all users, e.g., programmemanagers, human engineering specialist designers, and operational personnel.4) The development of computer software tools for human engineering analyses andof application-specific human engineering specifications, and the growing use ofcommercial specifications for procurement, will require modifications to thecurrent approach to human engineering standardization in NATO.NATO UNCLASS-IFIED
