Visualizing a Procedure with Nassi-Schneiderman Charts
Edmond H. Weiss · Journal of Technical Writing and Communication · 1990
Nassi-Schneiderman (NS) Charts are a form of flowcharting invented in the early 1970s to ensure that emerging computer programs would be structured, that is, organized into strings and nests of allowable programming constructs. These same constructs, however, are inherent in manual procedures as well. Using NS Charts to diagram human procedures eliminates prose ambiguities and provides most of the advantages of decision tables and trees. At the least, NS Charts can be used to test the logic and completeness of traditional procedures. At the most, they can replace many of the traditional publications.
