We measure communication constantly. Email platforms report open and click rates. Websites track visitors and page views. Social platforms count impressions, reactions, shares, and comments. Organizations record meeting attendance, reports distributed, media placements, and campaign reach. These measures are useful because they tell us something important about whether information traveled and whether people encountered it.
But there is a problem: most of them measure communication at or near the point of delivery. They tell us much less about what happened afterward.
A message can reach every person in its intended audience and still fail spectacularly. People may encounter the information without understanding it. They may understand it but distrust its source. They may trust the information but remain uncertain about what it means for them. They may know exactly what they should do and still lack the resources, authority, time, access, or support necessary to do it. If we stop measuring at the point of delivery, we risk declaring communication successful before we have examined the outcomes that mattered in the first place.
Reach is important. It just is not enough. None of this means reach, impressions, engagement, or other communication metrics are meaningless. If people never encounter information, they cannot do very much with it. Distribution is a necessary part of many communication efforts, and these measures can help us understand whether channels and tactics are functioning as intended. The problem begins when measures of exposure become proxies for measures of success.
A million impressions can still produce zero understanding.
A high email open rate tells us that people opened an email. It does not tell us whether they understood its significance. Attendance at a community meeting tells us who was in the room, but not whether participants believed their concerns were heard. A widely viewed emergency message tells us something about distribution, but not whether people knew how to respond—or had the ability to do so. The distinction matters because organizations tend to optimize what they measure. If we define successful communication primarily through distribution and engagement, we become very good at producing things people encounter. That is not necessarily the same as helping people make better decisions.
In my last essay, I argued that communication did not happen simply because we said something. People encounter messages within an ecology of prior knowledge, culture, relationships, technologies, competing information, institutional experience, and trust. Meaning emerges through those interactions. If that is true, communication evaluation needs to account for that ecology as well.
Instead of asking only whether people received a message, we can begin asking a richer set of questions. What did people understand? How did they interpret the information? Did the communication strengthen or weaken trust? Did people understand what options were available to them? Could they distinguish what was important from what was peripheral? Did they have the capacity to act on what they learned? These questions move us beyond measuring outputs toward examining consequences.
One useful way to think about communication evaluation is through five interconnected dimensions: reach, understanding, trust, capacity, and action. Reach asks whether the relevant people encountered the information. Understanding asks what meaning they made from it. Trust asks how credibility, relationships, and prior experience influenced their willingness to take the information seriously. Capacity asks whether people had the practical ability to respond. Action asks what happened as a result.
I do not think of these as a simple funnel or linear sequence. Human systems are far too complicated for that. Trust can influence whether someone pays attention in the first place. Experience can affect understanding. Taking action can strengthen or weaken trust. The surrounding environment can shape every part of the process. The value of these dimensions is not that they create a tidy model. It is that they force us to look beyond the message itself.
And capacity may be the dimension we overlook most often.
Communication professionals understandably spend enormous effort trying to help audiences know what to do. Prepare for the storm. Report the safety concern. Attend the public meeting. Follow the health guidance. Adopt the new organizational procedure. Use the available resource. When people fail to take the desired action, the natural response is often to revisit the communication. Perhaps the message was not clear enough. Maybe we need another campaign, more reminders, better visuals, or different channels.
Sometimes we do. But sometimes people understood us perfectly. The barrier was somewhere else in the system.
A family may understand emergency preparedness guidance but lack transportation, disposable income, or a safe place to evacuate. An employee may know exactly how to report an organizational concern but believe, perhaps from experience, that doing so could jeopardize a career. A community member may understand how to participate in a public process but be unable to attend meetings scheduled during working hours. A person may understand health guidance while finding it incompatible with the realities of work, caregiving, transportation, cost, or access.
In each case, additional communication may do very little. The limiting factor is not knowledge. It is capacity.
That distinction has ethical consequences. When organizations assume that information should automatically produce behavior, responsibility can quietly shift from the system to the individual. People become described as resistant, disengaged, difficult to reach, uninformed, or noncompliant. Sometimes those descriptions may reflect genuine differences in attitudes or choices. But before we use them, we should examine the system.
Did we provide information people could understand and use? Did we listen to the constraints they identified? Were the available choices realistic? Did institutional processes reinforce the behavior we were encouraging? Were some groups asked to bear costs or overcome barriers that others were not? Strategic communication should not simply become better at persuading people to navigate poorly designed systems. Sometimes the ethical intervention is to redesign the system.
This is where Design Ecology changes how I think about communication measurement. If communication emerges from relationships among people, information, technology, institutions, and environments, then evaluating communication requires examining those relationships too. The message remains important, but it becomes one component of a larger system.
We can still measure reach. We should. But we can also study understanding. We can examine trust. We can identify barriers to action. We can observe how people actually interact with communication systems rather than assuming they interact with them as designers intended. We can ask stakeholders where communication breaks down and what makes information useful in their particular contexts. Most importantly, we can distinguish between a communication problem and a system problem.
That distinction may save organizations from repeatedly trying to solve the wrong thing.
Good evaluation begins with an uncomfortable question: What outcome were we actually trying to produce? If the objective was awareness, measures of exposure and recall may tell us something meaningful. If the objective was understanding, we need to evaluate understanding. If the objective was trust, clicks are unlikely to tell us very much about it. If the objective was behavior, we need to understand both what people chose to do and whether the surrounding system made that action possible.
The metric should follow the objective, not simply the platform that happened to deliver the message. That sounds obvious. In practice, it requires us to move beyond the convenient numbers already sitting on our dashboards.
Those numbers tell us something. They just do not tell us everything.
Before we ask why people did not act on our communication, we should ask whether we designed a system in which they could. Because the ultimate measure of strategic communication is not simply whether information moved. It is what people were able to understand, decide, and do because of it.
