"The greatest obstacle to a team's success is the ego of individuals." — Patrick Lencioni
In the context of software development, ego manifests when an engineer:
This phenomenon is sometimes encouraged by the "rockstar developer" or "10× engineer" culture widely promoted in the industry.
Spotting egocentric behaviors early prevents them from becoming anchored in the culture:
| Observable indicator | Question to ask | Hidden risk | |---------------------|-----------------|-------------| | Stand-up monopolized by 1-2 people | Do others speak without being invited? | Information silos, demotivation | | Defensive code review comments | Does the debate focus on facts or people? | Interpersonal conflicts | | Refusal to write documentation | Who will be able to maintain this module in 6 months? | Critical bus factor | | Public blame during incidents | Are we looking for the cause or a culprit? | Deterioration of psychological safety |
| Ego-related symptom | Measurable impact | |---------------------|-------------------| | Giant, undiscussed Pull Requests | Cycle time +40%, increased bug risk | | Refusal of pair programming | Reduced bus factor, slower onboarding | | Ownership bias ("my file, my rules") | Conflicts during reviews, hindered innovation | | Personal defense during post-mortems | Masked root causes, repeated incidents |
Internal research at Google (Project Aristotle, 2016) indicates that team performance depends primarily on psychological safety — a climate where everyone can express themselves without fear of humiliation. Toxic ego destroys this safety.
| Dimension | Ego culture | Collaborative culture | |-----------|-------------|----------------------| | Technical decisions | Centralized around "gurus" | Open prototyping and RFCs | | Merit attribution | Individual (solo presentations) | Collective (team demos) | | Failure management | Blame and justification | Causal analysis and learning | | Career | Promotions by visibility | Promotions by team impact |
In 2022, GitHub experimented with weekly "social coding sessions" where two cross-teams refactor a component together, camera and mic enabled. Result:
Paradoxically, oversized ego and impostor syndrome often stem from the same root: fear of losing legitimacy. The first compensates with over-confidence, the second with self-devaluation. Both undermine collaboration:
Ego isn't always negative: it can motivate self-improvement. But when it takes precedence over the common goal, it sabotages collaboration and stifles innovation. By cultivating psychological safety, collective ownership, and metrics aligned with team success, organizations transform this ego into creative energy rather than a brake.
Immediate action: remove an individual metric that feeds ego and replace it with a collaboration indicator before the next quarter.
