Apply Deploy to Strength

Before assigning someone to a high-stakes role, map the specific capability profile the role actually requires — not a generic "strong performer" template — and match it against what each candidate specifically has; a gap in the role-critical requirement is a match failure regardless of the candidate's overall excellence, and deploying excellence-as-proxy for role-specific fit produces failure.

Why This Is Best Practice

Origin: Zhuge Liang's 将苑 (Way of the General, ~220–234 AD) devotes Chapter 13 "智用" (Intelligent Use) to the principle of deploying people according to their specific capabilities, not their general status. The key passage: "智者取其谋，愚者取其力，勇者取其威，怯者取其慎。" (From the wise, take their strategy; from the strong, take their force; from the brave, take their authority; from the cautious, take their care.) The principle is not that the wise should only do strategy and should never be deployed elsewhere — it is that each person has a specific dimension of excellence that constitutes their deployable contribution to a specific type of operation. The great commander knows which dimension each person possesses and assigns operations to exploit that dimension, rather than assigning the person who is highest-ranked or most trusted overall.

The evidence in practice: Zhuge Liang assigned Zhao Yun (veteran, defensive specialist, renowned for composed operations under pressure) to holding and screening operations — roles that required exactly Zhao Yun's specific profile. He assigned more aggressive young generals to offensive thrusts that required their specific profiles. The campaigns that followed the 将苑 doctrine succeeded operationally. The campaign that did not — the Battle of Jieting (228 AD) — failed because Zhuge Liang assigned Ma Su to a role that required battlefield command experience specifically. Ma Su was among the most gifted strategic analysts in Shu Han; Zhuge Liang's personal affection for him was genuine; his overall talent was exceptional. But the Jieting assignment required the specific capability of battlefield unit command under pressure — which Ma Su had never done — not strategic analysis, which was Ma Su's actual strength. Zhuge Liang himself acknowledged the error: his grief at Ma Su's execution was not only personal, but acknowledged that his own matching failure had created the situation.
