UML diagrams are generally used when designing software and databases to make sure that the system will work as required and to reveal potential problems before building the final product.Ī sequence diagram models the interactions between objects in a system in sequential order over time. Sequence diagrams are one of the 14 diagram types that can be created using the Unified Modeling Language (UML). Unless you can tie the documentation to code in some way (Model Driven Architecture, generated documentation, etc) it's hard to get people to keep spending the effort keeping them updated.What are sequence diagrams and what are they used for? So a lot of the time the source code turns into the only reliable documentation. People stop using any of it because they aren't sure which parts are still accurate and which aren't. If it is not kept up to date, it rots very quickly. "As built" documentation can be incredibly useful, but only if it is kept up to date. The other problem with system documentation is that it has to be maintained. They get us most of the way there without having to train everyone on UML. But block diagrams are useful at communicating concepts. We don't use strict UML because in my experience, there are very few people who know what all the different UML symbols mean and what the nuances are. We occasionally do block diagrams when it helps explain things, or sequence diagrams when we have a complicated back and forth, for example our login flow. I am wondering if any of your projects are using UML and Sequence diagrams. Even if some coders left the team, the new engineers can just go through these and learn. Projects could be maintained so well with this. If Sequence diagrams or class diagrams are implemented, these would help a lot.ĥ. Also how many really are documenting their code. Instead of reading the code, you can just see the diagrams and understand logic, class hierarchy. Once you document it and lock it, it is same across the teams.Ĥ. Everybody would be on same page and understands it same way because it is not plain english or a JIRA story.ģ. It communicates in better pictorial languagesĢ. I still feel they are very relevant and robust for current and modern projects too.ġ. I learnt they did not really focus on those subjects or did not even learn them. The Product Managers unanimously said NO. I spent so much time in preparing the presentation and history of it. Most of the recent engineers did not agree with that. Everything is in “stories”, everything is in “JIRA Confluence”. Engineers are often mis-informed because there is no proper technical documentation. I see downsides of not using them in current days projects. I worked for some big companies while I was consulting - and they seldom using them. It is like another spoken language for engineers. UML, Sequence diagrams used to be very helpful to understand the project across teams and work together. I moved to Mobile Programming (Enterprise) from the days of C++/Objective-C on macOS and Linux machines.
