 Customer satisfaction by rapid, continuous delivery of useful software.
 People and interactions are emphasized rather 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.
Disadvantage
 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.

When to use Agile model
 When new changes are needed to be implemented. The freedom agile gives to change is very important. New changes can be implemented at very little cost because of the frequency of new increments that are produced.
 To implement a new feature the developers need to lose only the work of a few days, or even only hours, to roll back and implement it.
 Scrum is a widely used subset of agile software development.
