Collaborative requirements modelling

Collaborative requirements modelling and test generation catch bugs and bottlenecks associated with poor user stories. Synchronise your requirements in Test Modeller flowcharts, creating the accurate user stories and rigorous tests needed to develop quality software in short sprints.

Are software requirements damaging your systems?

Today, requirements continue to introduce an unacceptably high number of defects to software development, with remediation costs skyrocketing the longer these bugs go undetected. Critical information about the desired system often remains in people’s heads, or is scattered across poorly integrated artifacts. These user stories, tables and diagrams rely heavily on natural language that is ambiguous, incomplete, and incapable of defining complex logic. Bugs then enter code from miscommunication and misinterpretation, but testing cannot find them early as it derives tests slowly and manually from the incomplete specifications. As fast-changing systems grow ever-more complex, a new and collaborative approach is needed to reduce bug creation and rework.

Requirements modelling for parallel development and testing

Test Modeller provides collaboration requirements modelling with integrated test generation, enabling cross-functional teams to deliver quality software in short sprints. User stories, diagrams, and data in collaboration tools are all quick-to-import, using connectors to synchronise information in visual flowcharts. Ambiguity and incompleteness are quick and easy to spot in the logical models, working collaboratively to add missing paths and avoid bug creation. Once this “shift left” refinement has modelled complete requirements, Test Modeller generates concise, but detailed, user stories into your tools of choice. This communicates the user stories developers need to deliver changing requirements at speed, while enjoying the tracking capabilities of best-of-breed tools.

Model requirements to generate user stories and tests

The same requirements models that drive rapid development generate rigorous automated tests, testing and developing in parallel for truly continuous delivery. Automated coverage algorithms create the smallest set of test cases needed to cover all the requirements, or to target at-risk logic. This avoids test creation bottlenecks, while auto-generating test scripts to avoid the time lost automating tests. Rigorous test automation can instead be ready before a line of code has even been developed, testing rapidly and rigorously to find bugs before the next release. Test Modeller then makes it quick and easy to update user stories and tests at the start of the next sprint, collaboratively updating central models to regenerate linked requirements and tests.

Generate user stories and tests from Visio and Confluence

This short example demonstrates requirements modelling and user story generation using Confluence, Visio and Jira for an insurance system. Discover how:

  1. Test Modeller's configurable connectors import information from collaboration and requirements management tools, using flowcharts a source of truth for cross-functional teams.

  2. A VISIO connector maps fields and images to blocks in Test Modeller’s easy-to-use flowcharts, quickly selecting and embedding text from confluence to create detailed requirements models.

  3. Collaboratively refining the visual flows creates complete requirement diagrams, performing “shift left” testing that adds missing logic and drives faster development with less rework.

  4. Each flowchart can be combined quickly to form end-to-end models, with subject matter experts collaborating to combine their flows into a complete picture of integrated systems.

  5. Developers can work directly in the logically-precise flows to avoid miscommunication and bug creation, while Test Modeller further exports user stories to your management tool of choice.

  6. The automated user story generation creates the most concise set of user stories possible, including data tables to map complex system logic completely and unambiguously.

  7. The same requirements models auto-generate the smallest set of test cases and scripts needed for automated testing, testing and developing in parallel for truly continuous delivery.

  8. Test Modeller maintains links to the interrelated artifacts generated from its intuitive flows, updating central models to regenerate artifacts, avoid bottlenecks, and minimise technical debt.
