02 // CONCENTRATION
Single-point dependency
Identify areas with shallow knowledge coverage and single-point dependencies.
03 // DEPTH
Depth distribution
See depth per team member in each system area (Deep, Working, Limited). Plan pairing, handoffs, and mentoring.
04 // PRIORITIZATION
Automatic risk labels
Areas are labeled Hotspot, Watch, or Healthy automatically. Summaries explain the main risk factors at a glance.
05 // ACTIONS
Turn insight into action
When you spot a coverage gap, create an action to close it. Assign a team member, set a mentor, and track progress to completion - right from the area or team member page.
FAQ
Common questions
Does it need access to our code or systems?
No. Faultline doesn't connect to GitHub, your infrastructure, or any external system. Knowledge is entered by your team - no integrations, no read access, no monitoring required.
Is this a performance management tool?
No. Faultline looks at system areas, not individuals. There are no individual scores or rankings - just team-level coverage data to help you plan ahead.
How long does it take to get started?
Most teams are up and running in under 30 minutes. Add your team, define your system areas, and map who knows what. No integrations or installation required.
How is this different from a spreadsheet?
A spreadsheet can store who knows what, but it can't score risk, simulate absence, or surface single-point dependencies. Faultline turns that data into actionable insight - no formulas, no manual scoring.
