Software Engineering and Design

Lecturer: Dr A.F. Blackwell

No. of lectures: 12

This course is a prerequisite for the Group Project (Part II (General)).


This course aims to provide students with a practical set of skills for the development of usable, reliable and maintainable software systems. It assumes basic programming skills in Java, describing how these can be deployed in the construction of larger programs. Systematic design processes are described, suitable for use where a development team must create a product that will meet customers' needs. These include issues related to usability and relevance to the context of use. Some specialised problems related to safety-critical systems and real-time systems are discussed, with the help of case histories of software failure to illustrate what can go wrong. Finally a range of alternative planning and management methods for software projects are contrasted.


  • Introduction. The software crisis; why projects fail (London Ambulance case study); design and engineering perspectives.

  • Software construction. Decomposition and modularity; coding style; naming; configuration; testing; efficiency. [2 lectures]

  • Object-oriented design. Design as modelling; The Unified Modelling Language; use case analysis; class modelling; object interaction; state and activity descriptions. [2 lectures]

  • Interaction design. Interaction styles; user models; requirements gathering; prototyping; evaluation. [3 lectures]

  • Design challenges. Hazards; risk; reliability; management failure (CAPSA case study). [2 lectures]

  • Project management. Models and metaphors of development; waterfall model, including technical review structure; evolutionary and incremental models (Spiral, RAD, RUP); novel structures (Chief programmer, Pair programming, XP). [2 lectures]


At the end of the course, students should understand the ways in which writing programs that are usable, reliable and maintainable differs from the programming exercises they have engaged in so far. They should be able to undertake design of a moderately complex application in a systematic way: researching user requirements, decomposing and analysing system architecture, implementing that design so that it will be reliable and maintainable, and evaluating alternatives at various project phases from prototyping to commissioning. They should be able to select and manage appropriate organisational structures when asked to do so. They should be prepared for the organisational aspects of their Group project (in the case of Part II (General) students) or the design elements of their project and dissertation (in the case of Diploma students).
