Advantages of Incremental Delivery

(1) Customers can use early increments as prototypes and gain experience that informs their requirements for later increments

(2) Customers do not have to wait until the entire system is delivered before gaining value from it

(3) The most important system services receive the most testing because they are delivered first and integrated throughout

Explanation

Four advantages of incremental delivery are: (1) customers use early increments as prototypes without re-learning when the complete system arrives; (2) customers gain value immediately without waiting for the complete system; (3) the process maintains benefits of incremental development, making change easier to incorporate; (4) highest-priority services receive the most testing as they are delivered and integrated first.
