The Development Cycle is a studied and recognized series of actions in a design process that tend to lead to more successful production outcomes.
The Requirements part of the process is a discovery process, where stakeholders are given a formal way of reporting their needs through codified inquiry. Simply asking what someone “likes” or “needs” may result in a less effective response than a form that asks qualifiable, reliable questions about the product in question.
The Design part of the process is where the requirements are turned into actions in the design. Stakeholder requirements drive the answers to the key questions of the design.
Development is where the real product is produced, incorporating all the requirements and design.
Testing is where the product is used, reviewed, and benchmarked. If needs arise at any stage in the development cycle, they are reincorporated at the next cycle. After a few cycles, a product may stabilize.
