The Balanced Scorecard, introduced by Robert Kaplan and David Norton in Harvard Business Review in 1992 and developed in their 1996 book The Balanced Scorecard: Translating Strategy into Action, measures strategy across four perspectives: Financial, Customer, Internal Process, and Learning and Growth. It was a genuine breakthrough, pulling management attention away from the single lagging lens of the income statement. But two of those four perspectives, the Financial and the Internal Process, quietly depend on something most organisations do not actually have: a true, activity-level picture of cost. Without it, the scorecard measures strategy with two of its four dials guessing.
The four perspectives, and the two that hide a cost problem
The genius of the Balanced Scorecard is balance. The Customer perspective captures how clients see you. The Learning and Growth perspective captures the capabilities and culture behind everything else. These two are largely non-financial, and the scorecard handles them honestly. The trouble lives in the other two.
The Financial perspective is supposed to answer “how do we look to shareholders” and almost always carries a profitability KPI: margin by product, by segment, by region. The Internal Process perspective is supposed to answer “what must we excel at” and tracks cycle time, quality, throughput. Both of these are running on cost data, and in most companies that cost data is built from allocations and averages. That is the soft spot the scorecard never advertises.
The profitability KPI that is really revenue minus a smear
Look closely at a typical “profitability by customer” or “margin by product” metric on a scorecard. It is revenue, which is precise, minus a cost that has been spread across the portfolio using overhead rates, headcount splits or percentage-of-sales allocations. The revenue is real. The cost is a smear. So the KPI is real revenue minus a fiction, reported to two decimal places and trusted as if both numbers were equally solid.
This is how a scorecard can show a customer segment as profitable for years while it is, in truth, destroying value, because the cost to serve it never landed on it. The Financial perspective looks rigorous. It is rigorous on the half it can measure and credulous on the half it allocates.
How TDABC repairs the Financial perspective
Time-Driven Activity-Based Costing, developed by Robert Kaplan and Steven Anderson in Harvard Business Review in 2004 and in their 2007 book, replaces the smear with a measurement. It builds a capacity cost rate, the fully loaded cost of a resource divided by its practical capacity, and time equations that describe how long each activity actually takes. From that, it traces real cost to the product, order and customer that consumed the work. The margin KPI on the Financial perspective stops being revenue minus an average and becomes revenue minus the cost that specific thing genuinely caused. The same logic underpins our work on cost to serve, where the difference between an average and a traced cost routinely flips a customer from green to red.
How TDABC repairs the Internal Process perspective
The Internal Process perspective is where strategy meets operations, and it is where TDABC’s second contribution lands. A scorecard that tracks cycle time and defect rates is measuring the operational symptoms of a process. TDABC measures its financial reality: the euro cost of the capacity each process consumes, and crucially the cost of the capacity it does not. That unused-capacity line, invisible to a conventional scorecard, is often where the real money sits. Improvement initiatives such as Lean and Six Sigma can then be read on the scorecard in money, not just minutes.
| Perspective | What the scorecard measures | What TDABC adds |
|---|---|---|
| Financial | Margin and profitability KPIs, usually revenue minus an allocation | True margin by product, order and customer, traced not smeared |
| Internal Process | Cycle time, quality, throughput | The euro cost of capacity each process consumes, plus unused capacity |
| Customer | Satisfaction, retention, share of wallet | Which of those valued customers are actually profitable to serve |
| Learning and Growth | Skills, systems, culture | The cost rate of the capabilities being built, so investment has a denominator |
Strategy maps you can finally price in euros
Kaplan and Norton added Strategy Maps in 2004 to make the cause-and-effect logic of the scorecard explicit: invest in skills, which improves a process, which delights a customer, which lifts financial results. Beautiful as a diagram, the arrows usually carry no numbers. They are hypotheses. With a TDABC model behind the map, the link from “process improvement” to “financial result” can be quantified in euros: this much capacity freed, worth this much at this cost rate, reaching the bottom line only if it is removed or redeployed. The strategy map stops being a belief system and becomes a measured chain.
Half a scorecard is a strategic risk
None of this is a criticism of the Balanced Scorecard. It is the most influential management framework of the last three decades, and it is built on a genuinely sound idea. The point is narrower and sharper: two of its four perspectives are only as good as the cost data underneath them, and in most companies that data is allocation, not measurement. Run those perspectives on averages and you get a scorecard that is balanced in form and unbalanced in truth, confident about customers and capabilities, and quietly wrong about money. This is the same connective logic we follow from TDABC versus traditional ABC all the way up to the Balanced Scorecard and TDABC together.
If your scorecard reports profitability that nobody fully trusts, the cost layer is usually the reason.

To scope a Balanced Scorecard plus TDABC engagement, book a scoping call. A Balanced Scorecard without real cost is half a scorecard. TDABC supplies the other half.
