  1. Determine and Apply Appropriate Development Methodologies The waterfall method

  2. THE WATERFALL METHOD

  3. What is the Waterfall method? • The waterfall method is a sequential flowing process. It only goes in one direction and if a previous step needs to be refined then the process must be restarted.

  4. When and how was the waterfall method created? • In 1970 a man by the name of Winston W. Royce wrote an article on a methodology, this methodology was not referred to as the waterfall method but was the core start of the waterfall method.

  5. Creation cont. • In 1974 Dr. Barry Boehm began work on refining the model and completed his iteration of the model in 1976, his revision was developed to ensure the model worked best with current management.

  6. Advantages • It provides the project management team with a clear overview of what needs to be achieved and how to go about it so they can organise the implementation of the project. • One of the oldest system development methodology’s and therefore has been refined to provide a clear and easy to understand outline of the goals that need to be achieved for the completion of the project.

  7. Disadvantages • The major setback of the waterfall methodology is that it is a sequential based system development methodology that allows no room for re-evaluation. • Another setback in this methodology is that due its structured nature

  8. Examples • The buying a laptop exercise we undertook in class.

  9. Would the Waterfall method be suitable for a network or System/Network Administration project? • This method would not be suitable for network administration as it would require too much time restarting if any mistakes were made. • Although a configured iteration could be suitable.
