Quantify dependency risk from blocked items, ownership clarity, and complexity.

Dependency Risk Heatmap scores delivery risk from blocked dependency ratio, dependency criticality, ownership clarity, and integration complexity. Use it during sprint planning, release readiness, program reviews, and escalation meetings when external teams, vendors, APIs, or approvals could become schedule bottlenecks. The tool returns a 0-100 risk index and a risk band so teams can compare dependency pressure across workstreams. It is a prioritization aid, not a substitute for dependency mapping, owner follow-up, or delivery judgment.

Input Pattern
Enter values in the left panel, keep units explicit, run the calculation, then copy or share the result. Invalid fields are highlighted immediately.
How to use this tool
Enter total dependencies and how many are currently blocked.
Score criticality, ownership clarity, and integration complexity on the 1-5 scales shown in the form.
Click "Assess Risk" and review blocked ratio, dependency risk index, and risk band.
Share the inputs with the result so owners can challenge the scoring and agree on next actions.
Formula or method
Blocked dependency ratio carries the largest weight because active blockers are the clearest delivery risk signal.
{"Ownership clarity is inverted into risk"=>"unclear ownership increases the score."}
Criticality and integration complexity raise the score when blocked or fragile dependencies affect important paths.
Worked example
Comparing release dependency pressure
Total dependencies: 14
Blocked dependencies: 4
Criticality: 4
Ownership clarity: 2.5
Integration complexity: 3.5
Result: The heatmap returns a moderate dependency risk band with a numeric index for comparison.
Use the score to decide which dependency owner needs escalation, then update the inputs as blockers clear.
How to interpret the result
A dependency risk score is most useful when it starts a focused ownership and mitigation discussion.
A high blocked ratio usually deserves immediate owner follow-up.
Low ownership clarity can be as dangerous as technical complexity because no one is clearly accountable.
Critical dependencies should be reviewed even when the total number of dependencies looks manageable.
Common mistakes
Counting dependencies without separating blocked, risky, and merely tracked items.
Giving high ownership clarity when a name exists but decision authority is unclear.
Treating the score as a forecast date instead of a risk prioritization signal.
Sharing a risk band without the input assumptions behind it.
Review note and limitations
Method - weighted dependency risk index from blocked ratio, criticality, ownership clarity, and integration complexity.
Does not model dependency network structure, critical path dates, vendor SLAs, staffing, or probability distributions.
Does not replace program management, escalation, dependency boards, or delivery owner judgment.
Planning support only. Confirm owners, dates, blockers, escalation paths, and delivery commitments before changing plans.
FAQ
What does the dependency risk index mean?
It is a 0-100 weighted score combining blocked ratio, criticality, ownership risk, and integration complexity.
Should every dependency have the same criticality score?
No. Use the score that best represents how damaging the dependency would be if it stayed unresolved.
Can this replace a dependency board?
No. It summarizes risk pressure, but a dependency board should still track owners, dates, decisions, and mitigation work.
