Software Development: Testing

This presentation discusses the role and purpose of testing in the systems/Software Development Life Cycle. We examine the consequences of the 'cost curve' on defect removal and how agile methods can reduce its effects. We concentrate on Black Box Testing and use Equivalence Partitioning and Boundary Value Analysis to construct the smallest number of test cases, test scenarios necessary for a test plan.

Introduction to Soft Systems Modelling

Two lectures that introduce the idea of modelling in the large, and contrasts hard system and soft system modelling. The second lecture goes into detail on a number of specific methods for analysing a system (CATWOE and CSH) and on modelling a system (Systems Diagrams and Personas).
