Development Methodologies

Iterative Development Process and Agile Methodologies

Client Interaction

Iterative Development Process:

• In this methodology, client interaction occurs at various stages of development.
• Clients provide feedback after each iteration, allowing for adjustments.
• Continuous engagement ensures that the final product aligns with client expectations.

Agile Methodologies:

• Agile methodologies place significant emphasis on regular client collaboration.
• Clients are involved in the planning, reviewing, and iteration processes.
• Feedback loops are shorter, promoting dynamic adjustments based on client input.

Teamwork

Iterative Development Process:

• Team collaboration is crucial, but roles may be more defined in each iteration.
• Teams often consist of specialists working on specific aspects during iterations.

Agile Methodologies:

• Agile promotes cross-functional teams with collective ownership.
• Team members collaborate closely, fostering adaptability to changing requirements.

Development Methodologies

Documentation

Iterative Development Process:

• Documentation is vital for each iteration but may not be exhaustive initially.
• Updates and refinements are made as the project progresses through iterations.

Agile Methodologies:

• Agile encourages comprehensive yet adaptable documentation.
• Documentation is maintained throughout the development process, reflecting evolving requirements.

Measurement of Progress

Iterative Development Process:

• Progress is measured through the completion of each iteration's goals.
• Regular reviews with stakeholders ensure alignment with project objectives.

Agile Methodologies:

• Progress is gauged by the completion of user stories and features.
• Incremental releases provide tangible indicators of project advancement.

Adaptive vs Predictive

Iterative Development Process:

• Adaptive in nature, as it allows for adjustments based on feedback.
• Changes can be implemented easily, even late in the development process.

Agile Methodologies:

• Highly adaptive, responding quickly to changing requirements.
• Embraces change throughout the project, even late in development.

Testing

Iterative Development Process:

• Testing is integral to each iteration, ensuring the quality of the evolving product.
• Continuous feedback and adjustments improve the effectiveness of testing.

Agile Methodologies:

• Testing is ongoing throughout the development life cycle.
• Emphasis on automated testing to maintain quality during rapid iterations.

These development methodologies, whether following an iterative approach or embracing agile principles, provide dynamic frameworks that cater to the evolving nature of software development. Each methodology has its strengths, promoting client collaboration, teamwork, and adaptive practices to deliver successful projects.
