6.1.1-3 Consistency With Other Portions of the HSI

The design of group-view displays, including information presentation and interaction characteristics, should be consistent with the rest of the HSI.

Additional Information:
Because group-view displays are to be used in conjunction with the rest of the HSI, consistency is necessary to support personnel in finding and using information. Guideline 1.1-17 states that consistent meanings should be assigned to codes, from one display to another. Generic HFE guidance should be tailored to specific HSIs and used to facilitate the standard and consistent application of HFE principles across the detailed design of the HSI. Since the group-view display is one part of the overall HSI, it should adhere to the same guidelines and standards of rest of the HSI, regarding such characteristics as modes of interaction, dialogue style, terminology, abbreviations, and symbols and other coding schemes. Differences should be based upon unique personnel task requirements that the group- view display is intended to support. However, obvious inconsistencies between the group-view display and the rest of the HSI, which may lead to confusion on the part of personnel, should be avoided. Examples of such inconsistencies may include presenting the same plant parameters with different units of measure or using unique coding schemes on one display device that may be confused with coding schemes used for other devices.
