With powerful schematic creation tools, designers work more efficiently than in general-purpose CAD systems and time-saving tools help them get the job done faster. Powerful project management tools automate the time-consuming and error-prone process of creating, updating, and checking many separate project documents.
Any change made in one area of a project will be reflected in all other relevant areas. For example, if a switch is substituted on a schematic for an alternate part, any references to that switch in the BOM, wiring list, or other documentation will reflect the change.
