Software maintenance: redocumentation of existing Cobol systems using hypertext technology
One of the major problems associated with the maintenance of existing software systems is their lack of documentation. This can make very large, poorly structured programs very difficult to maintain. Nearly all traditional documentation tools are either designed for use in the development stage of the software lifecycle or are report generators such as cross reference generators. The problems of lack of documentation are compounded when applied to third party software maintenance as the staffs are often initially unfamiliar with the code they are maintaining. This thesis describes these problems in detail and evaluates the feasibility of a tool to help with redocumentation based on current hypertext technology

Guidelines for the verification and validation of expert system software and conventional software: User`s manual. Volume 7
This report provides a step-by-step guide, or user manual, for personnel responsible for the planning and execution of the verification and validation (V&V), and developmental testing, of expert systems, conventional software systems, and various other types of artificial intelligence systems. While the guide was developed primarily for applications in the utility industry, it applies well to all industries. The user manual has three sections. In Section 1 the user assesses the stringency of V&V needed for the system under consideration, identifies the development stage the system is in, and identifies the component(s) of the system to be tested next. These three pieces of information determine which Guideline Package of V&V methods is most appropriate for those conditions. The V&V Guideline Packages are provided in Section 2. Each package consists of an ordered set of V&V techniques to be applied to the system, guides on choosing the review/evaluation team, measurement criteria, and references to a book or report which describes the application of the method. Section 3 presents details of 11 of the most important (or least well-explained in the literature) methods to assist the user in applying these techniques accurately
