Aggregate for risks

Notable Risks

Invalid Mission with RTL Causes Crash

Severity: High (3/3)

Rationale

A critical bug where uploading an invalid mission during flight can cause a crash during Return-to-Launch (RTL), posing a significant safety risk.

• Evidence: Issue #23340 details that an invalid mission upload can lead to a crash during RTL.
• Reasoning: Crashes during RTL are critical as they occur during an emergency procedure, potentially leading to loss of the vehicle and endangering safety.

Next Steps

• Prioritize fixing this bug immediately.
• Implement additional validation checks for mission uploads to prevent invalid missions from being accepted.

Continuous Integration (CI) Failures Due to VTOL SITL Tests

Severity: High (3/3)

Rationale

The failure of VTOL SITL tests on every pull request is a critical issue that disrupts the CI process, delaying development and integration of new features.

• Evidence: Issue #23275 details that the RTL direct rally without approaches forced test is failing consistently on every PR.
• Reasoning: Continuous integration failures can halt the development pipeline, preventing new code from being tested and merged, which can significantly slow down project progress.

Next Steps

• Assign a dedicated team to investigate and resolve the root cause of the VTOL SITL test failures.
• Implement temporary workarounds or disable the failing test if necessary to unblock the CI pipeline while a permanent fix is developed.

Decline in Team Velocity

Severity: Medium (2/3)

Rationale

There is evidence of multiple PRs being left open without resolution, indicating a potential decline in team velocity.

• Evidence: Multiple PRs such as #23236, #23233, #23229, #23228, and #23227 have been open for several days without resolution.
• Reasoning: While not critical, the accumulation of unresolved PRs can slow down development progress and indicate potential bottlenecks in the review process.

Next Steps

• Assign dedicated reviewers to address the backlog of open PRs.
• Implement stricter timelines for PR reviews and merges to ensure timely progress.

Prolonged Disagreement on Gimbal Control Logic

Severity: Medium (2/3)

Rationale

The changes in PR #23236 regarding gimbal control logic adjustments suggest potential prolonged disagreements or complexities in achieving consensus on control mechanisms.

• Evidence: The detailed changes in gimbal control logic and the need for extensive testing across different scenarios indicate potential areas of disagreement or complexity.
• Reasoning: Disagreements or complexities in core control logic can delay feature releases and affect overall project stability.

Next Steps

• Facilitate discussions among key stakeholders to reach a consensus on gimbal control logic.
• Conduct thorough testing and gather feedback from users to validate the changes.

Ambiguous Specifications for EKF2 Enhancements

Severity: Medium (2/3)

Rationale

The recent updates to EKF2 modules such as innovation sequence monitoring (#23233) and mag spikes preflight errors (#23229) indicate ambiguous specifications that may lead to implementation challenges.

• Evidence: The issues and PRs related to EKF2 enhancements involve complex algorithms and state estimation logic, which may not be clearly defined.
• Reasoning: Ambiguous specifications can lead to multiple rewrites and delays in achieving stable implementations.

Next Steps

• Clarify specifications and acceptance criteria for EKF2 enhancements.
• Engage domain experts to review and refine the implementation details.
