PART B

The Tables and PHP pages used in the following questions are described in Appendices A, B, C & D.

Question 1. [6 marks]

Briefly explain the differences between the Waterfall and Agile methodologies with regard to System development.

Need to include things such as:

Rather than developing the whole system as in the Waterfall method, Agile breaks the system down into builds or iterations, which contain specific and complete functions. These iterations are then fully developed and delivered to the client.

When using Agile, developers don’t have to include as much prediction in their development

Agile allows for easier changes as the project progresses
Agile allows the client to get an idea of the system functionality and look and feel much quicker

Agile is much more likely to deliver a product which meets the client requirements as they have been involved through each of the builds

Question 2. [6 marks]

Identify and briefly describe the 3 different types of prototypes a developer may use as part of their design approach.

Low fidelity

Usually rough and paper based

Allows rapid feedback on concepts and colours

Medium fidelity

Usually produced using a computer based tool

Usually able to demonstrate behavior such as interaction and navigation

High fidelity

Usually a high-tech representation of the application

Can provide partial to complete functionality

Usually provides almost complete UI
