Question : PUCIT is currently running through different departments like Administration Accounts , Examination , Admission , Library , Computer Labs , Faculty Management and Student Management etc . Every department has its own specific process and each department is using computer -based system to some extent . It is decided by the higher management that all the departments should be integrated i under one system where they must work independently . Higher Management wants to see this system within this year . Risks , which can arise , should be accommodated implicitly keeping the time factor in mind What Software Process Model would you choose and why ? State your assumptions clearly , if any , and give logical reasons in support to your answer . Solution : Stated Facts : 1. System is decomposed in different components 2. Every Component is automated to some extent but running stand alone 3. Management wants a system under which all components will run independently Time constraint is there 5. Risk will be accommodated implicitly Assumptions 1. As components are automated to some extent , even then these components will be restudied and analyzed , so that these can be run under one system independently 2. There will be system level interface to access components but rights of each user will be specified and restricted as per user policy 3. Team resources are sufficient available through which parallel development can occur 4. Since components are already a automated to some extent , so historical data will certainly help us to understand the components Similarly risks occurrence will be reduced Selected Process Model : "RAD Model " Reasons for selecting RAD Model : 1. As the system is already decomposed into components ; so it will be feasible for us to make RAD team for each component as we have sufficient human resources
