A impelling example of this would be; Requirements analysis, structural specification, design, implementation, testing and maintenance. There ar several types of lifecycle models. Two of the most unremarkably used are the falls lifecycle and the spiral lifecycle. The Waterfall Lifecycle Model The waterfall lifecycle was the primary winding publicly put down life cycle model. The model was developed to help cope with the increasing complexity of aerospace products. It was first documented by Royce in 1970. The waterfall lifecycle is in possible fulfill a sequential model but as indicated in the example above by the upward pointing arrows it is necessary to be constantly going back and going everywhere what has already been done. This could be for trouble shooting or quality lay out across proposes for example. It many cases it is not possible to continue the true task if the previous task is incomplete. On the other hand, if possible, it may font the timetable of the particular project if two of the stages overlap for each one other. It would depend on the project that was being worked on. As the waterfall model is a sequential lifecycle model, it is widely used in the manufacturing industry.

A good example of this would be the motor industry as cars are assembled sequentially. The advantage of the waterfall model is that it a very lucid lifecycl e and it is clear to see the direction in wh! ich a project is heading. One of the down sides is however the node is or guest may have difficulty stating explicitly the requirements at the incision of...
