Staged Delivery is a model of software development lifecycle. We usually used waterfall model. But waterfall model find serious problem to step of testing therefore maintenance cost is increased and schedule is delayed in the end of project. As a result iteration method proposed to resolve the problem in the software process. Iteration method repeats steps of requirements analysis, design, implements, testing to the unit of Concern. Therefore it find bug in the software as far as possible.
But it is difficult if you don’t know about whole domain because you can’t seperate the unit of module so you can’t develop the high priority module early.
Staged delivery is hybrid method. It is used to resolve the problem. Staged Delivery method make progress waterfall method by the design. Then implements and testing are made progress iteration method. It can seperate high priority module in the whole system through analysis and design.
next selected module is developed to iteration method. “If you can’t develop to iteration method, develop Staged Derivery method.”
