CORE DEFINITION

For important projects, a leader must be assigned who is responsible for nothing else (single-threaded), fully owns the success or failure of the project, and has the authority to mobilize resources, rather than relying on cross-departmental collaboration (which is often inefficient).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Accountability lock. If a project is someone's 'side job', it is doomed to fail. Only when it is a person's 'full-time' job and tied to their career success or failure can miracles happen.

Anchor fast decisions

If an important project is led by a part-time person, their attention is divided by original duties, and their success or failure is not tied to their interests, making it inevitably inefficient; a single-threaded leader (100% full-time with equal authority and responsibility) makes accountability unique, resources mobilizable, and success or failure rests on one person.

Glass Walls

Distinct from the 'glass ceiling' (vertical promotion barrier), it refers to women or minority groups being isolated in certain functional departments (e.g., HR, administration), making it difficult to move laterally to core business departments (e.g., sales, R&D), thereby lacking the key experience needed for promotion.

Inertia

Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its velocity to change. It is one of the fundamental principles in classical physics, and is described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). It is one of the primary manifestations of mass, one of the core quantitative properties of physical systems.
