​Key features - Iterative development process

Development process is completed in set stages which are completed one after the other.
Documentation is produced at every stage of the development process.
The client is heavily involved at the start of the project in order to produce the requirements specification. They are also involved at the evaluation stage.
Testing is done once a completed solution has been developed.
Teams of developers with particular skills work together with some interaction between teams at the end/beginning of a stage.

​Key features - Agile development process

Emphasis is placed on the development of various prototypes which are developed to form a completed solution.
There is limited documentation created for the solution.
The client is heavily involved throughout the development process, they give feedback on the prototypes which helps to shape the final solution.
Testing and evaluation is completed throughout the development process.
There is a heavy emphasis placed on teamwork and face to face communication between developers and the client.
