What Is Storyboard Flowcharting?

New method for documenting a process. Clean and simple flowcharting method. Allows for clients and auditors to clearly understand

process under review. Simple technique that requires a good graphics

package and a little imagination. Can use Microsoft PowerPoint, Harvard Graphics,

Corel Draw, etc. Does not replace IS flowcharting.

The Basics of Storyboard

Meet with client and document process. Use your imagination to choose/draw picture. Under picture write narrative for each step represented. Be creative - good control narrative in green; poor controls in red. Completed storyboard must be reviewed with client. Make any changes necessary. Final copy should be in color for most effective presentation. Different process may require different approach.
