modified waterfall model

the rigidity of the waterfall model aids project management with well-defined milestones and deliverables. the spiral model is a software development model designed to control risk. prepare a security plan: ensure that security is considered during all phases of the it system life cycle and that security activities are accomplished during each of the phases. the first delivery to the customer is a prototype of the envisaged system.

modified waterfall model ppt

a number of problems with the traditional waterfall model was making it seem redundant. in this software development process, there is a steady flow from one phase into the other. it is known as the traditional or pure waterfall model. how is it different from the traditional design? get in touch with us and we'll talk... the waterfall model came into software development from the manufacturing and construction industries. in this model, there are different phases the software goes through. however, once the software has progressed from one phase to the next stage, there is no way the software can go back to the previous stage. this model in software engineering came into existence because of the defects in the traditional design.

model extreme programming

as a type of agile software development,[1][2][3] it advocates frequent "releases" in short development cycles, which is intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted. jeffries thereafter acted as a coach to instill the practices as habits in the c3 team. extreme programming also introduces a number of basic values, principles and practices on top of the agile programming framework. code, say the proponents of this position, is always clear and concise and cannot be interpreted in more than one way. a new value, respect, was added in the second edition of extreme programming explained.

the prototyping model of software development is

in this model, a prototype of the end product is first developed, tested and refined as per customer feedback repeatedly till a final acceptable prototype is achieved which forms the basis for developing the final product. this document is used to build the initial prototype supporting only the basic functionality as desired by the customer. a) rapid throwaway prototyping – this technique offers a useful method of exploring ideas and getting customer feedback for each of them. b) evolutionary prototyping – in this method, the prototype developed initially is incrementally refined on the basis of customer feedback till it finally gets accepted.
