11/22/2023 0 Comments Uml timing diagramUML provides a very expressive modeling language that allows different people in the software development process to get the information they are interested in. Also, it facilitates communication between various developers. Why use UML?īy using UML, the entire software design is easier to read and understand prior to software development, thus reducing development risks. There are many tutorials, tools, examples and use cases on the Internet to get going.UML stands for Unified Model Language, which is a standardized modeling language consisting of a set of 14 different types of UML diagrams. Getting familiar with UML diagrams, even as a non-developer, made me better prepared to support their documentation effort.įor more information, start at or. Each step in the diagram will be linked to individual Confluence wiki pages with more detail. I am currently helping some managers who have used sequence diagrams to map out work. Visuals encourage speedy comprehension of even complex processes.

Time is a scale that remains constant, so a timing diagram can keep cycles “in sync” or “in proportion” with each other, which is something that can easily get distorted in PowerPoint. I needed a real-life example to practice a timing diagram so I tried to capture a typical rhythm of releases, milestones and Agile sprints and story points. Some of the steps are notifications, not actions, which helps ensure that the appropriate people are notified at certain A]] In the actual diagram, the green ovals are linked to anchors on the Confluence page with more details about each step, but here they are linked to Google so you can see the syntax. Now they are better equipped to contact people depending on where things are at. To outsiders it was understandably confusing. If tests failed at any point in the process, it was “back to square one.” To insiders, this process was second nature and based on personal relationships. This one was an important and complicated process involving no fewer than five roles and several rounds of testing. new person to create accountsĪs I got better at diagramming I could tackle more complex processes. In the actual diagram each step has a link to the instructions for doing it.Įveryone who sees this diagram “gets it” immediately and having a clear path to follow has made onboarding much smoother. It’s now more obvious that account creation happens before access is granted, which had been confusing before. Using an activity diagram with swimlanes required us to a) put the steps in sequential order and b) clarify who did what. The manager was surprised when I fired up Visual Studio Code during our discussion but the rigor enforced by a UML diagram had immediate benefits. Role3 -> Role1 : Sends different info Activity diagram: Onboarding processĪ team’s onboarding process needed review. One advantage of diagrams is that they can be edited in-page instead of having to edit a PowerPoint presentation, export slides as static images and then insert them into a wiki footbox This sequence diagram shows the same information exchanges as the slide but is much tidier. PowerPoint can be useful as a thinking tool but sometimes results in messy slides with many arrows as people think things through. } Sequence diagram: Roles and relationships The left-to-right orientation fits well with the page layout. Each node contained a link to a corresponding wiki page with more details. I used Bob Swift’s Digraph macro to create it. This was an early effort to visually depict the change in status of Jira issues as work progressed. Note: To replicate these diagrams, you may need to adjust the syntax slightly depending on your versions of Confluence, GraphViz.exe, and macros mentioned below. The examples are real but simplified and “anonymized.” It turns out that using UML diagrams in this way has some benefits and advantages, explained below. The sequential nature of certain business processes seemed to be a good fit, so that’s where I started. I had to find other, real-life applications to practice my diagramming skills. As a non-developer, I don’t use UML diagrams to document code. Our different perspectives got me thinking. “I’ve used timing diagrams, but I’ve never seen them used to capture business processes before.” “I have some serious cognitive dissonance going on here,” he laughed. It compared the timing of Agile sprints, feature development, software releases, and development milestones. Recently I showed a technical program manager a UML timing diagram I made while learning to create them.
