Skill silo

As explained in Think Like a Software Engineering Manager

A skill silo is a concentration of specialized knowledge or capability in too few people, limiting team redundancy and transferability.

A skill silo forms when specialized knowledge or capability is concentrated in too few people. If one person leaves, the team may inherit a skill gap. Cross-training and knowledge sharing reduce that risk. section 8.4.3

Reduce skill silos proactively:

  • Cross-train teammates so critical capabilities do not depend on one person. section 8.4.3
  • Build bench strength and encourage knowledge sharing across the team. section 8.4.3
  • Use new assignments and learning opportunities to broaden employees’ experience. section 8.4.3

Defines the risk and recommends proactive cross-training and knowledge sharing, but does not detail a training plan.
Examples
Uses employee departure, cross-training, knowledge sharing, and an offboarding checklist as practical anchors.
What you can do after

How it connects
Connects skill silos with attrition, cross-training, bench strength, and knowledge sharing.
