Sr Prototype RAD 1 Do not have detailed requirements for functions & features. Developers are not sure about efficiency of an algorithm & technical feasibilities Requirement are precisely defined and there is no change in the requirement 2 Working model can be achieved after long time. But in starting phase prototype is well defined. Working model can be achieved within short time 3 The developer team that have less experience on similar project Developer team must be well experienced. 4 Compare to RAD model less costly model Can be a costly model to use 5 It can be used, If the number of resources is less It can be used, If sufficient number of resources is available. 6 Quick initial reviews not possible. Quick initial reviews occur. 7 This approach is suitable for high risk project Not suitable for high technical risk project
