It is akin to brainstorming but focuses on creating models to visualize ideas and solutions. Model Storming sessions are typically short, time-boxed meetings intended to address immediate issues that arise during development.
The primary goal of Model Storming is to facilitate quick understanding and decision-making among team members. By collaboratively creating models, such as diagrams or sketches, team members can visualize complex concepts, clarify misunderstandings, and explore alternative solutions. This collaborative modeling enhances communication and helps in aligning the team's understanding of the system or feature being developed.
In the context of Agile Modeling, Model Storming supports iterative development by allowing teams to adapt and refine their models as new information emerges. It encourages active participation from all team members, leveraging their diverse perspectives to arrive at the best possible solutions. This approach also helps in identifying potential risks or design flaws early in the development process.
Model Storming sessions are informal and flexible, often involving simple tools like whiteboards or sticky notes. The emphasis is on quick, collaborative exploration rather than producing detailed, formal documentation. The models created during these sessions are typically temporary and evolve as the project progresses.
By embracing Model Storming, Agile teams can improve their ability to respond to change, enhance collaboration, and accelerate problem-solving. It aligns with Agile values by promoting individuals and interactions over processes and tools, and by encouraging teams to work closely together to deliver valuable software.
Guide to Model Storming
Why Model Storming is Important
Model Storming is important because it enables teams to rapidly solve specific design problems as they arise, rather than trying to plan everything upfront. It embodies agile principles by favoring just-in-time modeling over comprehensive documentation. This approach helps teams stay focused on delivering value, adapting to change, and maintaining momentum throughout development.
What is Model Storming?
Model Storming is an agile modeling technique where team members gather for brief, impromptu modeling sessions to address specific design challenges. Unlike traditional modeling that happens during a dedicated planning phase, Model Storming occurs throughout development when the need arises. It typically involves a small group of developers who collaborate to visualize and solve a particular problem using simple tools like whiteboards, sticky notes, or index cards.
How Model Storming Works
1. Trigger: A design challenge or question emerges during development.
2. Gather the right people: Assemble a small group (2-5 people) with relevant knowledge about the problem.
3. Time-box the session: Keep sessions short (usually 5-30 minutes) to maintain focus.
4. Model collaboratively: Use whiteboards or simple tools to create diagrams, sketches, or other visual representations.
5. Focus on the specific problem: Address only the issue at hand, not broader system concerns.
6. Document as needed: Capture essential insights, typically with a photo of the whiteboard or minimal notes.
7. Return to implementation: Apply insights promptly to coding activities.
Key Characteristics of Model Storming:
- Just-in-time approach - Highly collaborative - Informal and low-ceremony - Problem-focused - Minimal documentation - Temporary models that may evolve or be discarded
Exam Tips: Answering Questions on Model Storming
1. Understand the core principles: Emphasize that Model Storming is about just-in-time, collaborative modeling to solve immediate problems.
2. Contrast with traditional modeling: Be ready to explain how Model Storming differs from upfront detailed modeling (it's impromptu, focused on specific issues, and minimally documented).
3. Highlight the agile connection: Link Model Storming to agile principles like responding to change, customer collaboration, and working software over documentation.
4. Know the process: Remember the steps: identify a problem, gather the right people, time-box the session, model collaboratively, and document only what's necessary.
5. Provide concrete examples: Be prepared to give examples of when Model Storming might be used (e.g., designing a complex algorithm, resolving integration issues between components).
6. Address common misconceptions: Clarify that Model Storming doesn't mean avoiding all documentation or planning—it simply delays modeling until it's needed.
7. Explain the benefits: Discuss advantages like reduced waste, better team collaboration, and more relevant models that address actual rather than anticipated problems.
8. Describe common notations: Mention that UML, entity-relationship diagrams, or even informal sketches can be used based on what best communicates the idea.
9. Consider limitations: Acknowledge when Model Storming might not be sufficient (very complex systems, regulated environments requiring documentation).
10. Connect to other agile practices: Show how Model Storming complements practices like pair programming, test-driven development, and continuous integration.
