Software Design and Development

1. Development Methodologies

   • Agile
     • Client is involved throughout the entire process.
     • Teams of developers communicate together rather than working in isolation.
     • Spend time testing and adapting small cycles of coding.
     • No testing phase.
   • Waterfall
     • Client is heavily involved at the start and end of development
     • Teams mainly work in isolation.
     • Significant time is spent during the project design.
     • Testing is carried out.

2. Software Development Process

   • Analysis, Design, Implementation, Testing Documentation, Evaluation, Maintenance
   • Software specification is a legally binding document.

3. Analysis and Design

   • Purpose: A description and purpose of what the script must do.
   • Scope: List of deliverables that the project will hand over to the client.
   • Boundaries: The limits that help define what is in the project and what is not.
   • Functional Requirements: These are defined in terms of the inputs, processes and outputs.
