This guide outlines essential operational requirements for application design. Control, ergonomics, colors, fonts, information density, navigation, and efficiency are key factors to consider. Achieve user-friendly interfaces by reducing typing, minimizing clicking, displaying results promptly, and prioritizing synoptic and graphical data representations. Ensure seamless control, quick resets, and synergy across all operational functions. Remember that perfecting an application takes 2 to 4 years.
E N D
Operational Requirements • Control --- Operate
Ergonomics • Colors • Font sizes and types • Amount of information • Navigation • Avoid typing • Reduce clicking (are you sure)
Be Complete • Gain controls, resets (re-boots) must be possible from same application.
Be Simple • Graphs tell more than numbers • Synoptics tell more than words
Be Quick • The result of an action must be visible in the next cycle.
Synergy • All transfer lines must be operated from the same application.
Don’t forget • Polishing an application into an operational one, takes 2 to 4 years.
