The System Design Methods module is an optional module that forms part of the Level 6 PGD in IT – the final stage within the BCS three-stage Higher Education Qualification programme. Candidates will develop their understanding of the framework for building information systems and how these methods vary, ranging from informal guidelines to mathematical approaches, as well as which methods are applicable to which classes of application. This module is designed for candidates to explore methods appropriate for new classes of applications, and is especially relevant to those who are currently monitoring the implementation of a new method in their day-to-day role, or who are creating one for a specific set of circumstances. The overall aim of the module is to develop candidates’ understanding of system design methods, their critical practitioner’s knowledge of at least one method, and a general familiarity with several others across a range of application areas.
