Introduction to Agile Development

Duration: 3 days
Type: beginner


This course is a two part introduction to Agile Development. The first part is a theoretical discussion of what distinguishes Agile methods from traditional processes. The second part is an in-depth practical introduction to Agile tools and techniques. Examples are given from many different environments, including Java, C#, Ruby and Perl.

The first part of the course is suitable for anyone involved in softeare development. The second is designed for software developers only.


For the second part of the course delegates should be software developers with experience of working on medium and large scale projects.
