| Advantages | Disadvantages |
|---|---|
| Customer satisfaction by rapid, continuous delivery of useful software. | In case of some software, it is difficult to assess the effort required at the beginning of the software development life cycle. |
| Customers, developers and testers constantly interact with each other. | There is lack of emphasis on necessary designing and documentation. |
| Close, daily cooperation between business people and developers. | The project can easily get taken off track if the customer representative is not clear what final outcome that they want. |
| Continuous attention to technical excellence and good design. | Only senior programmers are capable of taking the kind of decisions required during the development process. |
| Regular adaptation to changing circumstances. | |
| Even late changes in requirements are welcomed |
