This book is about maintaining computer software. Its aim is to improve aprogrammers ability for altering code to fit changing requirements and fordetecting and correcting errors. Software maintenance is an important andtimely area of invetigation. It is the component that gives a system itsflexibility but it is also the source of many of its problems. Software isexpensive to maintain and is the usual cause of systems failures. Traditionalapproaches using software engineering and management disciplines do notadequately address maintenance issues. This book argues for a new way ofthinking about maintaining software proposing the use of a set of humanfactors principles that govern the programmersoftwareevent world interactionsand form the core of the maintenance process. The book should prove highlyvaluable for systems analysts and programmers managers seeking to reducecosts researchers looking at solutions to the maintenance problem andstudents learning to write clear unambiguous programs.
