Iterative and Incremental Software Development Methodology

An Iterative and Incremental Software Development Methodology is a software development methodology that can be used to create iterative and incremental software systems (that support software development tasks).

• AKA: Iterative and Incremental Development.
• Context:
  • It can typically divide Software Development Project into smaller iterative and incremental software development cycles.
  • It can typically deliver Functional Software Increments at the end of each iterative and incremental software development iteration.
  • It can typically incorporate User Feedback between iterative and incremental software development iterations.
  • It can typically reduce software development risk through iterative and incremental software development feedback loops.
  • It can typically improve software quality through iterative and incremental software refinement processes.
  • ...
  • It can often combine Software Prototype Development with iterative and incremental software feature addition.
  • It can often support Software Requirement Evolution through iterative and incremental software development cycles.
  • It can often enable Parallel Software Development of different iterative and incremental software components.
  • It can often facilitate Software Project Management through iterative and incremental software milestones.
  • ...
  • It can range from being a Simple Iterative and Incremental Software Development Methodology to being a Complex Iterative and Incremental Software Development Methodology, depending on its iterative and incremental software development process formality.
  • Simple Iterative and Incremental Software Development Methodologys typically involve fewer iterative and incremental software development ceremonys and iterative and incremental software development artifacts.
  • Complex Iterative and Incremental Software Development Methodologys typically incorporate extensive iterative and incremental software development governance and iterative and incremental software development documentation.
  • ...
  • It can range from being a Short-Cycle Iterative and Incremental Software Development Methodology to being a Long-Cycle Iterative and Incremental Software Development Methodology, depending on its iterative and incremental software development iteration length.
  • Short-Cycle Iterative and Incremental Software Development Methodologys typically involve iterative and incremental software development iterations lasting days to weeks.
  • Long-Cycle Iterative and Incremental Software Development Methodologys typically involve iterative and incremental software development iterations lasting weeks to months.
  • ...
  • It can integrate with Software Testing Processes for iterative and incremental software quality assurance.
  • It can support Software Configuration Management for tracking iterative and incremental software versions.
  • It can complement Software Architecture Design through iterative and incremental software architectural refinement.
  • ...

  • Iterative and incremental development is any combination of both iterative design or iterative method and incremental build model for development.

    Usage of the term began in software development, with a long-standing combination of the two terms iterative and incremental having been widely suggested for large development efforts. For example, the 1985 DOD-STD-2167

    mentions (in section 4.1.2): "During software development, more than one iteration of the software development cycle may be in progress at the same time." and "This process may be described as an 'evolutionary acquisition' or 'incremental build' approach." In software, the relationship between iterations and increments is determined by the overall software development process.
