Introduction

As our politicians have recently been keen to emphasise, change is an inescapable fact of modern life. When applied to software products, even over the lifetime of a relatively small product, we can expect to see requirements, customers and technologies change. For more complex products, in addition to these changes, markets, laws and regulations, organisational structures and cultures may all change. Even our understanding of the best way to reach a solution, will undergo radical changes over the lifetime of a project.

Earlier software engineering approaches failed to take this onslaught of change into account. Consider waterfall-based approaches: these rely on the ability of produce comprehensive specification documents early in the project, which can then be set in stone, after which development happens followed by testing late in the project, when significant amounts of code have been written. Such an approach is fundamentally at odds with a situation where change will happen. The result of using such approaches was very large cost overruns on project's that delivered late, or failed to deliver any useful product.

An agile approach recognises that change will happen. Products are delivered incrementally, with testing used from the early stages of a project to both test code and detect when a change breaks functionality that has already been developed. To achieve this requires processes, tools and techniques that minimise implementation development effort and maximise code quality. How these processes, tools and techniques make software development agile is what this course unit examines.

Aims

This course unit continues the exploration of agile software development ideas that was begun in the second year software engineering project. The aim is to give students a broad awareness of how the underlying concepts of agility, specifically the need to adapt to change, impact on both the process and technical aspects of software development. By the end of the course unit, students should be well placed to make decisions as to whether to adopt an agile or a more traditional route in various circumstances, and when using an agile approach, the tools and techniques that give the ability to respond to change.

In terms of process aspects, we will take as our starting point the four key principles that underlie agile software engineering. We will examine each one from various viewpoints: as a critique of more traditional software engineering processes and as a starting point for exploring approaches that could work better for projects likely to be subject to pressures of change. Students will have a chance to try applying some of the techniques and critiquing them.

In terms of technical aspects, we will examine how by raising the abstraction level at which software is developed and by combining this with semi-automated implementation generation, implementations can be rapidly adapted to cope with the effects of change. Students will experience some of these tools and techniques.

Syllabus

The course unit will contain sessions on both agile processes and agile tools and techniques.
