Economic process modeling: Business cases beyond cost accounting


Cortney Pagel has learned to expect a particular question whenever she proposes changing how work gets done. Pagel, a senior business analyst and change manager at ENGIE Impact, often hears it from the digital side of the organization before she has finished explaining the change: How much money are we looking to save here? “I don’t always have an answer,” she says. “And so that is very frustrating for me.” The frustration comes from a familiar structural problem. Most financial systems connect money to departments, accounts, cost centers and, in more mature implementations, activities; however, they rarely connect economics to the anatomy of the work itself. Pagel describes processes that are still too manual to be tracked cleanly, while in other cases the financial detail exists but was never tied to the process model. For a period, she resorted to putting cost estimates in comment bubbles on process diagrams because there was no systematic place for them. “There’s been no great system or method to do it,” she says. “It’s definitely not just me.” The question she keeps being asked therefore exposes a broader lacuna in management accounting . Finance can usually explain what a process consumes, and it can often estimate what a proposed change might save. Yet it is far less equipped to show which process components contribute value, which destroy it, which absorb risk and which create information or options whose economic effects may surface much later. Consequently, a transformation business case can become highly precise about one side of the equation while leaving the other largely narrative. A ledger on the ledge of usefulness The general ledger reports what a department or cost center consumes. Activity-based costing (ABC) , where organizations have implemented it with sufficient discipline, pushes that resolution further by assigning costs to activities. Both approaches remain useful; nonetheless, their analytical center of gravity is consumption rather than contribution. They can tell management where resources were spent with increasing granularity, while offering much less visibility into what an individual activity economically produced. Double-entry accounting, dating back 500 years to Venetian merchants, earns its reputation for symmetry, although the symmetry belongs primarily to bookkeeping. The two sides of an entry describe the same financial event, while revenue generally appears when a transaction is recognized rather than carrying a lineage back through the many process components that helped create it. A renewal, expansion, avoided loss, faster decision or improved customer relationship may depend on dozens of steps, yet the contribution of any one step rarely has an account to which it can be posted. This creates an analytical asymmetry that can influence investment decisions more than finance leaders may realize. When a CFO or operating executive evaluates a proposed process change, the cost side often arrives quantified while the value side arrives as prose, judgment or a collection of indirect metrics. The quantified side therefore tends to carry disproportionate weight because it is already denominated in the unit in which the decision is made: money. Indeed, acknowledged uncertainty may be safer than one-sided precision, because the latter can carry the authority of a number while obscuring what the model omitted. One process, many economic artifacts Consider the process of customer onboarding. Operationally, it is a sequence of tasks needed to establish a customer, configure services, obtain approvals and move the relationship into a steady state. Economically, however, those same steps may establish relationship patterns that influence retention, create the account depth that enables a later cross-sell, generate behavioral and preference data whose usefulness compounds over the customer lifecycle, and reduce churn risk through investments made well before the customer has a reason to leave. Embedded in that same process may be approval controls whose original compliance rationale has waned, manual handoffs between systems that were never integrated, duplicate checks and wait times that gradually erode the loyalty the process was intended to build. Some components may therefore create value; others may protect it and still others may quietly consume it. Yet a conventional cost model compresses this heterogeneous mesh (or mess!) of economic activity into a single process cost, which is useful but incomplete. Improving or transforming the process requires a more discriminating account of what each component is doing economically: which steps build value, which erode it, which create unnecessary friction, which absorb risk, which generate ancillary benefits and which perform economic work that becomes visible only after the step is removed. Without that component-level view, an efficiency initiative can readily eliminate something valuable simply because its cost was easier to suss than its contribution. Sample customer onboarding — economic process model. LINQ.it Putting economics on the process map Economic process modeling (EPM) supplies that missing layer. As I described in a recent column, Business Transformation Needs a True Economic Approach Rather Than Guesswork , EPM decomposes a process into its constituent components—the information flows, human decisions, system actions and organizational touchpoints that make up the actual work—and then attributes economic effects to each across five dimensions: revenue contribution, cost and friction, risk exposure, option value and information value. The component level matters because the economically significant finding often sits buried within the process as a whole. Two steps that look roughly equivalent on a process diagram may carry very different economic profiles once attribution is applied. A seemingly minor validation step, for example, may generate information that reduces downstream risk, while a more conspicuous approval step may be largely vestigial. A cost-only review can easily misread the two because it sees effort more readily than consequence. Pagel describes the capability she wants in similarly practical terms: the ability to see processes at an organizational level, understand what they cost in aggregate and then break those economics down step by step. That level of resolution helps because process transformation decisions are rarely made at the level of an abstract end-to-end flow; they are made by automating, eliminating, combining, outsourcing or redesigning individual components. Consequently, finance needs an economic view at the same level where the design decision is actually being made. The oft-ignored value of information itself Information value is where this analytical oversight may be most acute, particularly because most processes today generate data as a byproduct of execution. For example, a credit review produces repayment-behavior signals, a claims intake creates fraud indicators, and a procurement approval accumulates supplier-performance evidence. Those outputs may have future utility well beyond the transaction or process that generated them, even though conventional cost accounting typically has no place to represent them. Most organizations, however, still treat much of this data primarily as documentation, exhaust or a compliance burden rather than as a potentially monetizable asset. A process redesign can therefore appear efficient while externalizing, degrading or destroying information whose economic contribution was absent from the business case. Infonomics , the discipline of treating information as an economic asset with attributable value, provides the grounding for this dimension of EPM and helps expose value that can otherwise disappear during an ostensibly sensible transformation. From cost review to capital allocation EPM extends cost accounting by adding an economic perspective the ledger wasn’t designed for. Sure, cost remains an indispensable computation. However, the business case becomes materially more complete when the components proposed for automation or elimination are also evaluated for revenue contribution, risk absorption, optionality, information yield and the friction they create or remove. This can change the quality of the capital-allocation discussion. A step that costs $500,000 annually certainly may be a strong automation candidate, yet the savings figure is incomplete if the same step prevents $2 million in avoidable losses, preserves a customer relationship, generates valuable information or creates an option the business may need later. Conversely, a relatively inexpensive step can still be economically destructive if it adds delay, rework or customer attrition. The point is not to manufacture spurious precision around every benefit; rather, it is to make the relevant sources of value visible, estimable and subject to the same scrutiny as cost. Which brings us back to Pagel and the question she hears whenever she proposes a change: “How much money are we looking to save here?” Savings are only one side of the economic case. The more consequential question may be what each affected component contributes today, what value may disappear if it is changed, and what new value the redesigned process could create. Indeed, a transformation can look compelling when the savings are visible and the value at risk remains invisible. Economic process modeling gives finance a way to juxtapose both in the analysis, so that a proposed change can be judged not merely by what the organization expects to spend less, but by what the work itself is actually worth.
