ArboNET Database “Users don’t know what they really want, but they know for certain what they don’t want." Manubay’s Laws for Programmers Keep it simple – avoid complex and multi-layered data entry screens whenever possible Build data entry screens to work the way data entry clerks actually enter the data Where possible, build compatibility with other data collection systems (e.g., NEDSS, etc.)

Use drop-down lists, auto-fill and other time savers whenever possible (automatically calculate totals, statistics, etc.) Build error checking routines into the software Use lists to prevent spelling errors and similar problems "Never attribute to malice that which is adequately explained by incompetence."
