CS607 Requirements and Design Engineering

Requirements capture and monitoring, design, coding and acceptance testing

We focus on the often-overlooked requirements gathering activity, and a lot of software design. We examine a wide variety of requirements gathering techniques and learn how and when they should be applied. The design component is largely, though not exclusively, focused on the UML.

1. Requirements Elicitation

    Qualities found in successful software projects.
    Qualities found/absent in un-successful software projects.
    The User Requirements Document (IEEE/ANSI 830-1993)
    Knowledge Elicitation Techniques
    Behavioural Requirements
    Non-Behavioural Requirements
    Document Validation

Software Patterns
Standard solutions to standard problems, including a brief overview of some anti-Patterns.

Case studies are used throughout this course. One model is taken from the banking sector, a distributed application with a centralised database. We also examine a model of the manufacturing domain, with complex interactions among a large number of communicating objects. Practicals focus on developing models of both these domains.

We compare the models developed under the OO methodology with that produced by structured design. We analyse these to see the large number of advantages brought by object orientation.

Limitations: We also look at some possible limitations of Object Orientation.

Are there cases when useful Objects cannot be identified?
When is "information hiding" a help or hindrance?
Is inheritance a panacea?
