Automation lowers the effort per campaign and raises the baseline load your team carries. A calculation that contains only the saving describes the build. Operation is missing from it.
The number of automated flows is rising. In the ongoing bvik survey 2026, 78.8 percent of the marketing decision makers surveyed are investing in AI for marketing processes and 63.9 percent in AI agents and process automation.
Budgets are not growing with them. In 2025, B2B marketing budgets fell by 3.1 percent, the first decline in five years. At the same time, 87 percent of respondents reported rising prices for externally purchased services, up 17 percent on average. The real decline is therefore considerably larger than the nominal one. For the next three years, 44 percent expect stable and 19 percent falling external budgets.
The bottleneck is rarely technology. In the ZHAW Marketing Automation & AI Report 2024, 72 percent name limited resources and skills as the biggest obstacle to AI in marketing. Data protection concerns and technical limitations follow at a distance.
That explains how little reaches regular operation. In the same survey, 44 percent are learning and exploring, 44 percent are testing with pilots and 5 percent are scaling broadly. In lead management, the only area the study breaks down in detail, actual AI use stands at around 10 percent.
Chromedia calls the missing item operating load, in German Betriebslast: the share of team capacity that goes into maintaining existing automation.
Operating load is not total cost of ownership. TCO covers licences, implementation and infrastructure, items that appear in a budget. Operating load covers team capacity only, the item that appears nowhere. It consists of approvals, data corrections, model reviews and the coordination required for every change to product, price or audience. It accrues for as long as the flow runs, whether or not that flow still delivers anything. According to the Gartner Marketing Technology Survey 2025, 49 percent of deployed marketing tools are actively used.
What operating load looks like in numbers
There is no reliable survey on the operating effort of automated flows in marketing. Software engineering has one. Robert L. Glass puts maintenance at 40 to 80 percent of the total cost of a piece of software, 60 percent on average. An automated flow is configured software. Related to the build, operation therefore falls between two thirds and four times as much.
An example with 30 active flows. Each one takes around a week to build initially, so 150 person days in total. Over its lifetime that produces between 100 and 600 person days of operation, 225 on average. Spread across three years, that is 33 to 200 person days per year.
The point is not the number but the range: between seven weeks and a full time position. If you do not know where you sit in that range, you are planning capacity by instinct.
Three principles
Every flow has an owner and a review interval
Whoever built a flow is not automatically the person who reviews it. Define at go live who is responsible and how often the review happens. Automation without an owner keeps running, including when it is wrong.
The business case includes the first year of operation
Build effort and expected saving are the easy half of the calculation. The other half is maintenance, approval, data correction and model review across twelve months. Only with that half is the business case complete.
Every new flow replaces an existing one
Decide before you build which existing flow the new one retires. Operating load you free up is the budget for the next expansion. Without that question, the estate only grows in one direction.
The sentence for the budget conversation
Capacity for operation is not sloppy planning, it is preserving the value of an investment you have already made. Anyone running 30 flows holds 150 person days of build effort. That capacity protects the value, it does not compensate for inefficiency.
A self test for this week
Half an hour is enough. Count your active automated flows and ask three questions about each: who reviews it, when was it last reviewed, what would replace it. Every flow without an answer is unknown operating load. If nothing can be retired, that is a result too: the estate is at its capacity limit and the next flow needs additional people.
From saving to calculation
A business case for automation is complete once it includes the first year of operation. Until then it only describes the build. Knowing your operating load means you can manage it and free it up for the next expansion.
