TCB™ · THE CORPORATE BODY

A study-style management framework

TCB™

THECORPORATE BODY

Stop forcing people into a bell curve. Reward departments for their real contribution to your products, the way the human body feeds its organs according to what it is doing.

The problem

When the curve becomes more important than the truth

In a team of ten, a forced distribution allows one top rating, two fours, six threes, and someone must land at the bottom even if nobody underperformed. The manager stops evaluating performance and starts fitting people into a pre-decided shape.

What they deliveredWhat the curve allows

8 of 10 people rated below what they actually delivered.

“This is not performance management. This is performance allocation.”

The idea

A company is a body

The body doesn’t feed its organs by size or by a quota. It feeds them according to what it is doing: running, digesting, healing. TCB™ applies that discipline to variable reward, and adds the governance biology gets for free.

A companyis a body

An interdependent living system, not a machine.

Departmentsare organs

Each has a specialised role and its own measure of success.

Productsare activities

Each lifecycle stage draws on a different mix of organs.

Rewardsare calories

A finite pool, allocated to healthy contribution.

KPIsare vital signs

Signals of performance and of health.

Size is not importance

The brain is about 2% of body weight but uses about 20% of resting energy. Companies are full of brains: small teams with outsized consequence that a bell curve tends to overlook.

Evidence, not anatomy

The metaphor explains roles. Weights come from the Dynamic Contribution Matrix and its evidence.

Weights follow the lifecycle

Sales leads acquisition; operations, service and protection lead retention.

Set before the period

Funding, weights, ceilings and gates are approved and published in advance.

Health Gates

Results built on burnout, customer harm or hidden risk are reduced, or stopped at zero.

A testable experiment

Simulate, run a shadow pilot, and only then touch real pay.

The reward formula

One formula anyone can follow

Performance amount, capped at the department’s own ceiling, then its own Health Gate, then rounded down. What isn’t earned stays unpaid. It never moves to another department.

Ad = m × floor[ min(P × Wd × Sd, Ĉd) × Gd / m ]

Try it with the book’s Operations example. Move any slider.

For organisations

Pilot TCB™ in your organisation

TCB™ is offered as an experiment, and the safest way to test it is a structured 90-day simulation and shadow pilot on one product, with no change to anyone’s pay.

Days 1–30

Frame

Choose one product, name its lifecycle stage and outcomes, and set up the committee, conflict rules and review owners.

Days 31–60

Build

Run the weight-setting protocol, grade the data, define KPIs and Health Gates, and simulate on historical results.

Days 61–90

Shadow

Run alongside your current system, reproduce every calculation independently, gather feedback, and decide the next step.

No deadline for live pay. Real pay is considered only after legal, HR, pay-equity, payroll, privacy, risk and audit reviews have all passed.

Questions

Frequently asked

Isn’t a finite reward pool just another bell curve?

No. The pool limits funding, not the distribution of ratings. Every department can meet or exceed its target; each is capped only at its own pre-approved ceiling, and unearned amounts simply stay unpaid.

Does the body analogy decide who gets paid more?

No. The analogy explains roles. Weights come from an evidence-based protocol that scores each department’s causal influence, accountability, execution and criticality for a specific product and stage, approved before the period.

Could this become a disguised way to cut staff?

That is exactly what Health Gates are for. Results achieved through burnout, errors, customer harm, hidden risk or compliance breaches reduce the reward or stop it at zero.

How are independent risk, compliance and audit treated?

They stay outside the business product pool and are rewarded through a separately funded and independently governed route, so the business they oversee never decides their pay.

Can weights change in the middle of the year?

Ordinary changes take effect next period. Only a defined exceptional event can trigger a mid-cycle change, with non-conflicted approval, a new version and a prospective effective date. It is never used to reduce pay already earned.

Is TCB™ proven?

It is presented as a study-style hypothesis. The book sets out six hypotheses, a staged evaluation from simulation to shadow to real pay, and the results that would disprove the model.
