See knowledge risk at a glance

Enter which team members have knowledge of each system area and the depth of their understanding. Faultline maps areas by people count and depth distribution, labels them Hotspot, Watch, or Healthy, and links to area and team member views.

01 // CONCENTRATION

Single-person dependency

See how many team members have knowledge of each system area. Find areas that rely on one person.

02 // DEPTH

Depth distribution

See depth per team member in each system area (Deep, Working, Limited). Use it to plan pairing and handoffs.

03 // PRIORITIZATION

Area labels

Areas are labeled Hotspot, Watch, or Healthy. Reasons summarize the main factors.

How teams use Faultline

Set it up once, then review it periodically.

STEP 1

Add Team Members

Add your team members so each system area can list who has knowledge of it.

STEP 2

Define System Areas

Define the system areas your team owns.

STEP 3

Capture Knowledge Depth

For each system area, select team members and set depth: Deep, Working, or Limited.

STEP 4

Review Risk + Plan Actions

Use the map and labels to decide where to reduce single-person dependency and spread depth.

What you get

Dashboard map

System areas mapped by number of people and depth distribution.

Area detail views

For each system area: label, reasons, team members, and depth pips.

Reasons behind labels

Short reasons behind each label. Helps you see what needs attention.

Member perspective

System areas listed per team member, with depth pips. Helps spot concentration across the team.

FAQ

Is this performance management?

No. Faultline is about system knowledge distribution. It is designed to avoid individual judgement and focus on area-level risk.

Is this automated? Does it read our code?

No. Faultline is based on human-entered updates. It does not scan your repositories or monitor production.

How often should we update it?

You should review system areas on a regular cadence and after major changes. Updates should be frequent enough that the map reflects recent changes.
