I.COMPONENTS OF RAD
User involvement is key to success
Prototyping is conducted in sessions similar to Joint Application Design (JAD) Prototyping screens become screens within the production system CASE tools are used to design the prototypes
II.PROBLEMS ADDRESSED BY RAD
A.With conventional methods, there is a long delay before the customer gets to see any results.
B.With conventional methods, development can take so long that the customer's business has fundamentally changed by the time the system is ready for use.
C.With conventional methods, there is nothing until 100% of the process is finished, then 100% of the software is delivered.
III.EVALUATION OF RAD
A.ADVANTAGES Vs DISADVANTAGES
i.Since system are being developed quickly that could lead to lower overall system quality. ii.Though it works well where speed of development is important, that can lead to possible violation of programming standards related to inconsistent naming conventions and inconsistent documentation. iii.Users can change the system design which can cause difficulty in module reuse in the future. iv.There's a tighter fit between user requirements and system specifications which may have inconsistent internal designs within and across...
