This thesis has adopted the premise that the use of a method offers a valuable contribution to the software development process. Many methods have not been adequately defined. This thesis is based on the hypothesis that it is possible to represent software development methods using a Generic Method Representation (GMR). This GMR includes the three basic components of the method, which are the product model, the process model and the heuristic model. The elements and interrelationships of these models are investigated. In addition to a graphical representation, a method specification language (MSL) is derived, to enhance the expressive and executable power of GMR. A three-stage knowledge acquisition model, known as IFV (inspection, fabrication and verification), is also introduced to elicit method semantics from the available acquisition media. Moreover, the key benefits of meta modelling, such as method comparison, fragment dissection, method evaluation and selection (or customisation) of a method, are highlighted. An application of GMR, that is the mapping to a practical metaCASE tool model, is also illustrated comprehensively to demonstrate the applicability of the approach.
