further into the business-driven variant of IE, which was intended to address a rapidly changing business environment. The then Technical Director, Charles M. Richter, from 1983 to 1987, played a significant role by revamping the IE methodology as well as designing the IE software product (User-Data) which helped automate the IE methodology, opening the way to next generation Information Architecture. Computer-aided software engineering The Martin thread in information technology engineering was strategy-driven from the outset and from 1983 was focused on the possibility of automating the development process through the provision of techniques for business description that could be used to populate a data dictionary or encyclopaedia that could in turn be used as source material for code generation. The Martin methodology provided a foundation for the CASE (Computer-Aided Software Engineering) tool industry. Martin himself had significant stakes in at least four CASE tool vendors—InTech (Excelerator), Higher Order Software, KnowledgeWare, originally Database Design Inc, (Information Engineering Workbench) and James Martin Associates, originally DMW and now Headstrong (the original designers of the Texas Instruments' CA Gen facility and the principal developers of the methodology). At the end of the 1980s and early 1990s the Martin thread incorporated rapid application development (RAD) and business process reengineering (BPR) and soon after also entered the object oriented field. Rapid Application Development (RAD) Rapid application development (RAD) is a term originally used for describing a software development process first developed and successfully deployed during the mid-1970s by D.Dinadasa at Getahetta Telephone Co's Systems Development Center under the direction of Dan Gielan. Following a series of remarkably successful implementations of this process, Gielan lectured extensively in various forums on the methodology, practice, and benefits of this process. Martin introduced his approach in 1991. Martin's methodology involves iterative development and the construction of prototypes. More recently, the term and its acronym have come to be used in a broader, generic sense that encompasses a variety of techniques aimed at speeding application development, such as the use of web application frameworks and other types of software frameworks. RAD approaches may entail compromises in functionality and performance in exchange for enabling faster development and facilitating application maintenance. The Oxford Martin School In 2004 Martin donated £60m to help establish The James Martin 21st Century School, which in 2010 was renamed The Oxford Martin School, at the University of Oxford, in what was the largest single donation to the university.
