Software Development Methodologies

Method

Advantages

Agile

• Closer collaboration between developer and client.
• It is highly transparent.
• Requirements can be changed at any point throughout the process, including at later development phases.

• Difficult to assess.
• More difficult to understand in comparison to a linear methodology.
• Not enough emphasis on prior designing and Requirements quickly changing.

Method

Advantages

Disadvantages

Waterfall

• Each phase of a products life goes through a series of sequences
• Easier to understand for new developers or people new to software development.
• Development process is better documented as there is more emphasis on Requirements and design documentation.
• Fixed time scale for each section of the project.

• No program is produced until the end of the project.
• No room for error.
• Better for smaller projects
• Not suitable for ongoing/long projects
• Difficult when in testing stage as hard to modify or add extra features to the program.

Method

Advantages

Disadvantages

Code and Fix

• Can reach coding more efficiently.
• Coding is in constant development.
• New features can be added at any time.
• Can test the program anytime when developing

• Has no Requirements or design plan whatsoever.
• No planned final product, thus resulting in the product having no ‘end’.
• No flexibility as not planned for any modifications
