Quantify risks



Project Risk Ratings

Risk Level (1-5) Rationale
Delivery 4 The project faces significant delivery risks due to a backlog of unresolved issues and stalled pull requests. Notably, PR #10258 for upgrading to .NET 8 has been open for 136 days, indicating delays in critical updates. The backlog of 413 open issues, many related to Sonarr conflicts, further exacerbates these risks. The lack of test coverage in new code and incomplete implementations in several PRs (e.g., #10609, #10537) also contribute to potential delivery delays.
Velocity 3 The project's velocity is moderate but faces challenges due to the consistent opening of more issues than are closed. Over the past year, 329 issues were opened with only 200 closed, suggesting a trend that could slow progress. Additionally, several PRs remain in draft status or marked 'Don't Merge' due to unresolved issues, indicating bottlenecks in the review process that could impact velocity.
Dependency 4 Dependency risks are significant, particularly with the stalled upgrade to .NET 8 (PR #10258) and integration challenges with Sonarr commits leading to numerous conflicts (e.g., #10764). The reliance on automated processes for translations and the introduction of new dependencies like RQBit without thorough validation further compound these risks.
Team 3 The team faces potential risks related to resource constraints and prioritization challenges, as indicated by the backlog of unresolved issues and stalled PRs. However, active contributions from key developers suggest a committed team. Communication issues or pending actions from contributors (e.g., 'Waiting for OP' labels) could affect team efficiency.
Code Quality 4 Code quality is at risk due to the lack of test coverage in new code and incomplete implementations across multiple PRs (e.g., #10509, #10609). While some PRs pass quality checks, the absence of comprehensive testing suggests reliance on manual reviews or static analysis tools. The presence of security hotspots in stalled PRs further indicates potential quality concerns.
Technical Debt 4 Technical debt is accumulating due to unresolved issues and incomplete PRs that lack tests or documentation updates. The prolonged draft status of critical updates like .NET 8 upgrade (PR #10258) and missing components in new features (e.g., RQBit support) highlight areas where technical debt could increase if not addressed promptly.
Test Coverage 5 Test coverage is critically lacking across new code implementations. Several PRs introduce features without any tests (e.g., #10730, #10656), posing significant risks for undetected bugs and regressions. This systemic issue with test coverage could undermine software reliability and maintainability.
Error Handling 3 Error handling appears adequate in specific areas like disk operations (as seen in DiskTransferService.cs), but the overall lack of test coverage raises concerns about catching errors across the broader codebase. While logging and rollback mechanisms are present in some components, comprehensive error handling strategies are needed project-wide.
