Minecraft - Bugs Diagnose System

Speeding Up Bug Resolution for Developers.

Bug diagnosis in Minecraft's development pipeline was a slow and fragmented process, often taking weeks to resolve issues. Developers had to navigate 5 to 6 different tools to gather information, leading to frustration, miscommunication, and workflow inefficiencies.

As a Product Designer, I led the UX efforts to create an MVP web app that consolidated all necessary information in a single, intuitive dashboard—significantly reducing the time it took for developers to identify, understand, and resolve bugs.

The Challenge

Before our solution, the bug diagnosis process required:

  1. Debugger analysis

  2. Backlog bug tracking

  3. Gathering data (screenshots, logs, error types, etc.)

  4. Logging issues manually

  5. Reproducing bugs when necessary

  6. Finally fixing the issue

This highly manual process caused:

  • Massive backlogs of unresolved bugs.

  • Confusion about responsibilities and permissions (contractors, partners, leaders).

  • Inefficiency due to scattered info across multiple tools.

Designing the Solution

To address these challenges, I designed a web-based bug diagnosis system that:
✅ Streamlined workflows, reducing the number of external tools needed.
✅ Displayed all relevant bug data on one screen for quick understanding.
✅ Used Microsoft’s Design System for rapid development.

Product Requirements & Goals

🚀 Easy Diagnosis → Developers should understand 90% of a bug on the first screen.
🗂 Better Information Architecture → Reducing clicks and eliminating unnecessary steps.
🎨 Microsoft UI Components → Ensuring fast implementation with a tight deadline.
📉 Reduce Diagnosis Time by 40% → Lowering backlog issues and frustration.

My UX Process

1️⃣ User Research & Mapping Workflows

  • Interviewed 10% of end-users to identify pain points.

  • Mapped user flows based on roles.

2️⃣ Design & Prototyping

  • Created low-fidelity flows, validating user needs.

  • Designed UX & UI directly in Figma using Microsoft components.

  • Ensured clear information hierarchy using color-coded tags, data tables, and graphs.

3️⃣ Testing & Iteration

  • Conducted usability tests with 43 users, iterating based on feedback.

  • Implemented simplified navigation, reducing external tool dependencies.

4️⃣ Collaboration & Development

  • Worked closely with 10 developers to ensure seamless implementation.

  • Partnered with our PM to manage stakeholder feedback & align priorities.

Impact & Results

📉 Reduced bug diagnosis time by 40%.
📊 Lowered backlog issues, validated through PM metrics.
🎯 Increased efficiency, allowing developers to focus on fixes instead of documentation.
💬 Positive feedback across the organization.
🛠️ Fast adoption, with long-term plans for a fully integrated dashboard.

I’m grateful for my PM’s leadership and the developers’ collaboration, which made this a truly impactful UX solution for the Minecraft team.
