V-Model: Advantages, Disadvantages, Usage

22 Feb

According to ISTQB Exam Certification:

Advantages of V-Model are:

  • Easy to use
  • Simple to use
  • Testing activities like planning, test designing happens well before coding.
  • Time saving, quick
  • Hence higher chance of success over the waterfall model
  • Proactive defect tracking – that is defects are found at early stage
  • Avoids the downward flow of the defects
  • Works well for small projects where requirements are easily understood

Disadvantages of V-Model are:

  • Very rigid
  • Least flexible
  • Software is developed during the implementation phase, so no early prototypes of the software are produced
  • If any changes happen in midway, then the test documents along with requirement documents has to be updated
  • Risky

Use V-Model when:

  • Small to medium sized projects where requirements are clearly defined and fixed.
  • Sample technical resources are available with needed technical expertise.

High confidence of customer is required for choosing the V-Shaped model approach.
