Dedication, I dedicate this book to Douglas T Ross the father of. SADT and IDEFO with whom I worked for more than, thirty years The concepts presented here are his I have. tried to present his ideas as I have come to understand. and apply them to the real world I apologize to him for. any misleading statements herein or for dabbing on his. canvas as he used to put it,This page intentionally left blank. any different graphics software packages were used to produce the fig. ures in this book Thus the reader will see several variations in style. when reading the IDEFO diagrams presented here The use of a particu. lar package to produce a specific form of IDEFO diagram is not intended to imply. endorsement by the author In most cases the package used to develop an IDEFO. model was determined by the product used by the client for whom the model was. The following graphics packages were used to produce the diagrams in this. book listed in alphabetical order of the package name. Authormate by Eclectic Solutions Inc,AutoCad by Autodesk Inc.
