Most companies have adopted at least one idea from Robert Kaplan without realising how many of their management tools share a single author and a single logic. Activity-Based Costing and its successor Time-Driven Activity-Based Costing, the Balanced Scorecard, Strategy Maps and the Execution Premium are not four separate fashions. They are one connected system, developed over three decades, and Kaplan is the thread running through all of it. Adopt one and you have a tool. Operationalise all four as a single closed loop, with real cost as the backbone, and you have a management system. That second thing is rare, and it is what this piece is about.
The four ideas, and the one author
Trace the chronology and the design intent becomes obvious. Kaplan and Robin Cooper built Activity-Based Costing in the late 1980s to fix the distortions of traditional cost accounting. Kaplan and David Norton introduced the Balanced Scorecard in Harvard Business Review in 1992, and the 1996 book gave it four perspectives: Financial, Customer, Internal Process, and Learning and Growth. In 2004 they added Strategy Maps to make the cause-and-effect logic between those perspectives explicit. The same year, Kaplan and Steven Anderson published Time-Driven Activity-Based Costing, a faster, more scalable costing engine. And in 2008 Kaplan and Norton published The Execution Premium, the six-stage closed-loop system that finally tied strategy, planning, operations and cost into one managed cycle.
How they fit into one closed loop
The four ideas map onto a single loop, each answering a different question.
- Cost (ABC/TDABC) answers “what does anything really cost?” It is the measurement layer underneath everything, and the difference between traced cost and allocated cost is set out in TDABC versus ABC.
- The Balanced Scorecard answers “are we executing our strategy?” across four balanced perspectives, two of which depend directly on the cost layer.
- Strategy Maps answer “why, by what cause and effect?” linking learning to process to customer to financial outcomes.
- The Execution Premium answers “how do we manage all of this as one cycle?” through six stages, with Stage 4, Plan Operations, as the point where strategy becomes an operating plan and money.
Read in sequence, the loop is clean: cost feeds the scorecard, the scorecard feeds the strategy map, the strategy map feeds the execution system, and the execution system feeds decisions back down to operations and cost, where the cycle begins again. The reason it so often fails to close is that the cost layer at the bottom is usually allocation, not measurement, so every layer above inherits the error. A strategy map drawn on averaged cost cannot tell you which of its arrows actually carries money, and an execution review fed by allocated margin will reward the wrong initiatives with complete confidence. The loop does not break loudly. It simply learns the wrong lessons, year after year, while every dashboard above looks healthy.
Why cost is the backbone, not a footnote
It is tempting to treat cost as the technical plumbing under the strategic architecture. The opposite is true. The two cost-dependent perspectives of the Balanced Scorecard, Financial and Internal Process, are explored in why your Balanced Scorecard fails without real cost. The single stage of the Execution Premium where strategy meets money, Stage 4, is the subject of where strategy meets money at Stage 4. In both cases the conclusion is the same: get the cost layer wrong and the elegant structure above it quietly reports fiction. TDABC is the backbone precisely because it is the only layer that turns minutes, capacity and activities into euros that the scorecard, the map and the execution loop can all trust. Remove it and the other three ideas still function as diagrams and reviews, but they manage perceptions rather than money.
How it connects to the rest of our work
This system is not abstract. It is the spine that organises everything else we do. Cost to serve is the customer-profitability output of the cost layer, the truth behind the Customer and Financial perspectives. Lean and Six Sigma with TDABC is process improvement at Stage 4, where saved minutes only become profit if the freed capacity is removed or redeployed. Our work in value-based health care applies the same cost backbone to outcomes that matter in clinical settings, where TDABC supplies the cost denominator of value. Each of these is a facet of the same loop, with real cost holding it together.
The system we implement
Plenty of firms implement one piece. Costing specialists build cost models. Strategy consultants draw scorecards and maps. Few connect all of it into one operated loop, and fewer still put real, traced cost at the base where it belongs. That is the work Cost and Profitability Consulting does, and it is the reason we describe what we offer as a system rather than a service. We are not claiming to have invented any of these ideas. Kaplan and his collaborators did that, with the years and titles set out above. We are saying something more modest and more useful: this is the system we implement, end to end, with TDABC as the backbone, on the Balanced Scorecard and TDABC and strategy execution and TDABC pillars.
If you have adopted one or two of these ideas and sensed they were not yet pulling together, the missing piece is usually the cost backbone connecting them. Start with a free Profit Check, read how we work, or scope the full system directly with a scoping call. Cost, measurement, cause-and-effect and execution were always meant to be one loop. We close it.
