concurrent development model advantages and disadvantages

The client involvement is more and it is not always considered by the developer.It also identifies the confusing or difficult functions. It identifies the missing functionality easily.Gives quick user feedback for better solutions.The development process is the best platform to understand the system by the user.In the development process of this model users are actively involved.Prototype model need not know the detailed input, output, processes, adaptability of operating system and full machine interaction.When the users are satisfied with the developed prototype then the system is developed on the basis of final prototype.The process of refining the prototype is repeated until all the requirements of users are met.If the user is not satisfied with current prototype then it refines according to the requirements of the user.The prototype is evaluated by the customer itself. It allows the developer to better understand the exact requirements.This phase gives the clear idea about the development of software because the software is now built.It focuses on those aspects which are visible to the user rather than the detailed plan.It includes only the important aspects like input and output format of the software.Quick design is implemented when requirements are known.In this phase, developer and customer meet and discuss the overall objectives of the software.

The different phases of Prototyping model are: In this model, working programs are quickly produced.It is software working model of limited functionality.It does not identify the requirements like detailed input, output.Prototype model is a set of general objectives for software.Prototype is defined as first or preliminary form using which other forms are copied or derived.They allow to develop more complete versions of the software.įollowing are the evolutionary process models.ģ.Evolutionary models are iterative type models.What are the advantages and disadvantages of waterfall model over evolutionay model in a software development life cycle.

Invisible process not well-supported by documentation. The systems structure can be corrupted by continuous change. Evolutionary development model has more week point as well. in creative writing in 2008, specializing in novel-length historical fiction.During life cycle software is produced early which facilitates customer evaluation and feedback. degrees in both history and creative writing and earned her M.F.A.
