Advantages and disadvantages of Agile model

Advantages of Agile model:

  • People and interactions are given importance┬árather than process and tools. Customers, developers and testers constantly interact with each other.
  • Working software is delivered frequently (weeks rather than months).
  • Face-to-face conversation is the best form of communication.
  • Close, daily cooperation between business people and developers.
  • Continuous attention to technical excellence and good design.
  • Regular adaptation to changing circumstances.
  • Even late changes in requirements are welcomed

Disadvantages of Agile model:

  • In case of some software deliverables, especially the large ones, it is difficult to assess the effort required at the beginning of the software development life cycle.
  • There is lack of emphasis on necessary designing and documentation.
  • The project can easily get taken off track if the customer representative is not clear what final outcome that they want.
  • Only senior programmers are capable of taking the kind of decisions required during the development process. Hence it has no place for newbie programmers, unless combined with experienced resources.
