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.
