Generic Software Process Model Waterfall model

Generic Software Process Model Waterfall model The classic way of looking at Software Engineering. that accounts for the importance of requirements, design and quality assurance.

Generic Software Process Model Waterfall model The model suggests that software engineers should work in a series of stages. The waterfall model also recognizes, to a limited extent, that you sometimes have to step back to earlier stages.

Generic Software Process Model Waterfall model Problems It implies that you can get the requirements right by simply writing them down and reviewing them.

Generic Software Process Model Waterfall model Problems The model implies that you should attempt to complete a given stage before moving on to the next stage. This makes it difficult to respond to changing customer requirements after the process is underway

Generic Software Process Model Waterfall model This model is only appropriate when the requirements are well-understood
