The Most Important UP Idea: Iterative Development

5 important questions on The Most Important UP Idea: Iterative Development

What is the primary best practice promoted by UP?

The main focus is on ITERATIVE DEVELOPMENT, which involves:
  1. Short, fixed-length mini-projects called ITERATIONS
  2. Each iteration leads to a tested, integrated, and executable system
  3. Activities include requirements analysis, design, implementation, and testing

What does feedback from iteration N contribute to the next iteration N+1 in software development?

Feedback from iteration N is crucial as it leads to:
  • Refinement of the requirements
  • Adaptation of the design
  • Improved functionality in the next iteration

What key activities are performed in a two-week iteration during a project?

In a two-week iteration, activities include:
  1. Distributing and clarifying tasks
  2. Reverse-engineering last iteration's code
  3. Pair design work and creating UML diagrams
  4. Implementation and testing (unit, acceptance, usability)
  5. Integration and system stabilization

How does the iterative and incremental development process manage the growth of a system?

The growth of a system is managed by:
  • Implementing features incrementally
  • Working in fixed-length iterations
  • Allowing for adjustments based on feedback from previous iterations

What is the outcome of each iteration in the iterative and incremental development process?

The outcome of each iteration includes:
  • An executable but incomplete system
  • Not ready for production deployment
  • Requires multiple iterations (e.g., 10 to 15) for readiness

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
