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 activeness a sequential model but as indicated in the example above by the upward pointing arrows it is necessary to be constantly going b ack and going everywhere what has already been done. This could be for trouble shooting or quality stretch out across proposes for example. It many cases it is not possible to continue the flow rate task if the previous task is incomplete. On the other hand, if possible, it whitethorn font the timetable of the particular project if two of the stages overlap apiece 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 assiduity.

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 lifecy cle and it is clear to see the direction in ! which a project is heading. One of the down sides is however the client is or guest may have difficulty stating explicitly the requirements at the incision of...
