Personnel action plan from effort/impact matrix review

February 26, 2026 at 2:24 AMpeoplecritical

Situation

Conducted comprehensive effort vs. impact performance review of ~20 engineers across kernel and platform teams, resulting in specific personnel actions: underperformers on short improvement timelines or face replacement, one engineer to be replaced with a high-impact hire, one engineer requires direct performance conversation about ownership and visibility, one to be reassigned to simple packaging tasks.

Reasoning

The 2x velocity mandate requires removing drag — can't double output while carrying underperformers. The 'super senior guy in the corner' archetype (high depth, low effort) is about to be obsoleted by AI, collapsing the economic argument for tolerating low-effort seniors. Single points of failure (Secure Boot, STIG) are unacceptable risk requiring cross-training before any exits. The effort/impact matrix provides an objective, data-driven framework for personnel decisions.

Additional Context

Full-day in-person Linux Leadership Sync in San Jose with Nathan, Justin, Max. Part of operationalizing the 2x engineering velocity mandate set the day before.

Observed Evidence

Fathom Pt 1: Detailed effort/impact matrix review of kernel and platform teams. Specific action items assigned to Peter: 'Initiate a direct performance conversation with Michael', 'Replace [engineer] with a high-impact engineer'. Nathan assigned: 'Set a short-term improvement plan for Jason and Brett', 'Reassign Fathom to simple packaging tasks', 'Cross-train Joseph, Skip, and Andrew on Secure Boot'.

Reasoning Depth Analysis

Org Signal:Signals to the entire engineering org that the performance bar has been raised — the matrix makes it data-driven, not subjective
Who Affected:Every engineer not named in this review now has a clearer picture of what good looks like
Precedent:Using effort/impact matrices as the basis for personnel actions creates a repeatable, defensible framework
Consequences:Real personnel changes — some people will be let go. Cross-training actions are prerequisites to make exits possible without creating gaps
Timing:6-month clock on 2x velocity is ticking from yesterday's mandate
