The challenge
Recovery plans are usually written per system, but real incidents cut across systems that depend on each other in ways nobody has mapped — including circular dependencies that only surface once it’s too late to plan around them.
What I built
Designed and built a free visual tool that maps how systems actually depend on each other during recovery — not just a single application, but the web of upstream and downstream dependencies that determine what has to come back online, and in what order. Detects circular recovery hazards that would otherwise only surface during a real incident, and produces a topologically sorted recovery sequence.
Outcomes
- Maps multi-system dependencies and visualises how systems actually rely on each other during recovery, not just in normal operation
- Detects circular recovery hazards — dependency loops that would otherwise only be discovered mid-incident
- Produces a topologically sorted recovery sequence: the actual order systems need to come back online
- Hands the calculated recovery-time gap straight to Redline, connecting dependency mapping directly to cost
