Sample Simplistic UML Sequence Diagram for a use case Feel free to search and read further on use cases, for advanced concepts. And interaction/behaviour/sequence design is the glue between use cases & development. To summarize, specification design (aka use cases) is the glue between specification & development. Its alright if one must tone down the complexity, and scope out some of the items or scenarios.Īs a good project management practice, don’t just delete these scoped out items, but do mention under Scoped Out section, so that all stakeholders are formally aware. Of course, any errors or gaps in the requirement specification, can be rectified by working iteratively on the design with feedback from product owners.

When presented, a design should invoke remarks such as “this is exactly how I perceived“, “we didn’t realize substantial percentage of the steps, but these all look important“, or “we can see the complexity now”. As developers you would have used flowcharts or Entity-Relationship diagrams. For this we always should use diagramming technique. Furthermore, one should present the design in an effective manner as well. And this should be done in shortest time, without unnecessary iterations that can lead to re-coding by developers. The whole idea of efficient design is to prepare accurate blueprint of the solution, and detail to the point of conversion to development easily. Find below, in detail, and with an example, how this sequence diagram is so powerful in designing software applications.

And it tends to become complex since multiple layers are involved when building applications. Since it caters to dynamic behaviour & interaction aspect of web application. UML Sequence Diagram goes a long way in designing web applications efficiently.
