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. In the past 7 days, 9 issues were opened while only 1 was closed, indicating a growing backlog. Additionally, high-priority issues such as #121 and #120 involve missing data for specific tickers, which could affect data integrity and reliability. The prolonged open periods of pull requests like PR #25 and PR #11 further exacerbate delivery risks.
Velocity 4 Velocity is at risk due to the imbalance between issues opened and closed, with only 1 issue closed in the last 7 days compared to 9 opened. The concentration of commits by Virat Singh suggests potential bottlenecks if his availability changes. Extended open periods for key pull requests like PR #25 and PR #11 also indicate potential slowdowns in progress.
Dependency 3 The project has several dependencies that pose risks, including reliance on external models like MISTRALAI (PR #93) and integrations such as Azure OpenAI (Issue #114). The dependency on Virat Singh's contributions is also a concern if his availability changes. However, the project is actively managing these dependencies through ongoing development efforts.
Team 3 The team faces potential risks related to uneven workload distribution, with Virat Singh contributing the majority of recent commits. This could lead to burnout or dependency on a single developer. The low engagement from other team members might indicate communication challenges or motivation issues.
Code Quality 3 Code quality is generally maintained through structured designs and modular approaches, as seen in 'src/agents/charlie_munger.py'. However, the lack of comprehensive documentation and testing details in recent updates (e.g., PR #93) poses risks to maintainability and future understanding of the codebase.
Technical Debt 4 The project is accumulating technical debt due to the absence of detailed documentation and testing for recent changes (e.g., PR #93). Prolonged open periods for pull requests like PR #25 suggest integration challenges that could contribute to technical debt if not resolved promptly.
Test Coverage 4 Test coverage is insufficient, as highlighted by the lack of comprehensive testing details in recent pull requests (e.g., PR #93). This poses risks in catching bugs and regressions, especially given the complexity introduced by new integrations like Gemini models (PR #118).
Error Handling 4 Error handling is inadequate, with critical issues such as unhandled exceptions leading to crashes (Issues #116 and #95). The basic error handling in 'src/main.py' does not provide detailed logging or recovery mechanisms, posing risks to system stability.
