Building an Azure DevOps Extension for Collaborative Effort-Impact Matrix Prioritization

In modern software development, prioritization decisions often fall to product managers or business stakeholders, leaving developers feeling disconnected from the process. This creates a gap where technical insights are undervalued, and business priorities may not align with implementation realities. To address this challenge, I developed an Azure DevOps extension that democratizes the prioritization process through collaborative effort-impact matrix sessions.

The Problem: Disconnected Prioritization

Traditional prioritization methods often suffer from several issues:

1. One-sided decision making: Business stakeholders prioritize without technical input
2. Lack of transparency: Developers don't understand why certain items are prioritized
3. Misaligned expectations: Business impact doesn't always correlate with technical complexity
4. Reduced team buy-in: When developers don't contribute to prioritization, they're less invested in the outcomes

The Solution: Collaborative Effort-Impact Matrix

The extension implements a collaborative voting system where team members rate backlog items across three dimensions:

1. Effort: Technical complexity and implementation time
2. Technical Impact: Architectural significance and technical debt reduction
3. Business Impact: Customer value and business objectives The system automatically calculates an overall impact score (average of technical and business impact) and places items on a four-quadrant matrix:
4. High Impact / Low Effort (Priority 1): Quick wins
5. High Impact / High Effort (Priority 2): Strategic investments
6. Low Impact / Low Effort (Priority 3): Maintenance tasks
7. Low Impact / High Effort (Priority 4): Avoid or reconsider

Technical Architecture

Frontend: React with Fluent UI

The extension uses React 18 with TypeScript for type safety and Fluent UI for consistent Microsoft design language:

// Core interfaces for type safety
interface Vote {
effort: number;
technical: number;
 business: number;
}

interface MatrixItem {
storyId: number;
 effort: number;
 impact: number;
 quadrant: string;
}

interface Session {
 ownerId: string;
 ownerName: string;
 projectId: string;
 teamId: string;
 startedAt: string;
 joinedUsers: { id: string; displayName: string }[];
 backlogItems: any[];
 votes: { [storyId: number]: { [userId: string]: Vote } };
 matrix: MatrixItem[];
}

Azure DevOps Integration

The extension leverages the Azure DevOps Extension SDK for seamless integration:

// Initialize SDK and get context
SDK.init();
SDK.ready().then(() => {
  const webContext = SDK.getWebContext();
  const userInfo = SDK.getUser();
  // Access project and user information
});

REST API Integration

Direct integration with Azure DevOps REST APIs for data retrieval and updates:

// Fetch teams for the project
export async function getTeamsForProject(projectId: string): Promise<any[]> {
  const accessToken = await SDK.getAccessToken();
  const orgName = SDK.getHost().name;
  
  const response = await fetch(
    `https://dev.azure.com/${orgName}/_apis/projects/${projectId}/teams?api-version=7.1-preview.3`,
    {
      headers: {
        'Authorization': `Bearer ${accessToken}`,
        'Content-Type': 'application/json',
      },
    }
  );
  return response.json();
}

Data Persistence

Sessions and matrix data are persisted using Azure DevOps Extension Data Service:

export async function saveSessionData(projectId: string, session: any) {
  const extDataService = await SDK.getService<any>("ms.vss-features.extension-data-service");
  const collection = await extDataService.getExtensionDataManager(
    SDK.getExtensionContext().id, 
    await SDK.getAccessToken()
  );
  const key = `session-${session.startedAt}`;
  await collection.setDocument("sessions", key, session, { 
    scopeType: "Project", 
    scopeValue: projectId 
  });
}
