Musings on Throughput per Constraint Unit. In the TOC community, our most critical ratio is Throughput per Constraint Unit (T/Cu). I’m not convinced everyone understands the power of this metric. If you’re considering the past, profit is arithmetic (revenue minus cost). But if you’re predicting the future, profit is calculus (the difference between the rate at which Throughput is generated and the rate at which operating costs accrue). This means that if we want to make management decisions intelligently, calculus is required (and calculus is difficult). But here’s the thing. EVERY business, when forced to operate in an orderly (i.e., non-chaotic) state, assumes exactly the same configuration of resources. You have one Constraint (fleet of aircraft, in the case of an airline) that is consistently heavily loaded, and a large number of non-Constraint resources, all of which have protective capacity (baggage handling, crew scheduling, etc), enabling them to subordinate to the Constraint. This configuration means that there is a SINGLE resource that determines the rate at which the organization generates profit. This simplifies predictions and, therefore, management decision-making. Given that profit is the difference between the rate at which Throughput is generated and Operating Costs accrued—and given that the rate of the former is determined by the Constraint and the latter is reasonably constant—predictions can now be made with simple division. delta(T/Cu) ∝ delta(Profit) In other words, changes in T/Cu are proportional to changes in profitability. Throughput is pure contribution margin (revenue minus raw-material costs). But where are Operating Costs in this equation? A Constraint Unit is a unit of the organization’s capacity (remember, the Constraint is the pacesetter for the entire organization). And the organization’s capacity is exactly what your operating costs are paying for! Assuming that operating costs are fixed for the period under consideration, T/Cu enables managers to make surprisingly accurate predictions with minimal effort. It’s just as simple as the traditional cost-accounting approach to predictions—and it avoids the nonsense results.

What are the odds those tiki torch carrying neo-Nazis from Charlottesville would only rally once? Feels like it was an American intel op against Trump. That’s my working assumption.
