Your engagement survey shows how people feel. What does the work cost them?

What does an employee engagement survey measure?

It measures what people perceive about their work and their workplace, and that perception matters. Quebec's public health institute, the INSPQ, makes the point about workload: the workload a person feels is as important as the workload requested. A survey is the natural way to read what is felt.

An engagement survey asks the question in its own way. Gallup classifies employees as engaged, not engaged or actively disengaged from their answers to the statements of its Q12 survey, and describes engagement as a much higher bar than satisfaction. In its 2026 report, Gallup puts global engagement at 20% in 2025, the lowest level since 2020.

In OHA's reading, a survey does two things well: it follows a perception over time, and it compares units with one another. What it does not do alone is name what is consuming people's capacity. An engagement rate, however carefully measured, does not say which load is weighing or which decision would move it.

What does a capacity diagnostic read, and how is it different?

It reads what the work costs the people doing it, by separating load into five types: decisional, cognitive, emotional, relational and administrative. These are OHA's Five Loads, and each calls for a different response: an administrative load is lifted by removing an approval step, an emotional one by something else entirely.

A diagnostic asks questions too, but about specific working situations and how often they occur, not about an opinion. Statistics Canada asks this kind of question in its Canadian Survey on Working Conditions: in 2024-2025, 34.6% of managers reported doing unpaid work in their free time several times a month or more to meet work demands. That is a frequency, not a feeling. The form of the instrument is not what separates the two; the question asked and the use made of the answer are.

OHA reads the organization at three levels: the manager, the team, and the structures that make either sustainable or impossible. The Capacity Diagnostic produces a map, not a score: where load has concentrated and which load dominates in each function. It is also a baseline. At day 90 of the Capacity Circle™ OHA repeats the same measurement, so the question of whether anything moved is settled by the numbers that opened it. The post on what a capacity diagnostic actually measures goes through the three levels in detail.

The check below takes about a minute. It uses five of the ten statements in OHA's capacity self-portrait, one for each load, and shows the kind of question a diagnostic asks.

How do you choose between a survey and a diagnostic?

Start from the decision you need to make, not from the instrument. If the decision rests on a perception, such as whether morale is improving from one year to the next or which units stand out, the survey answers it.

If you already see a signal, such as departures bunched together, evenings of work nobody has counted or decisions reopened the following week, and the decision is what to change first, you need a reading of load by type and by function. That is the diagnostic.

If you must defend a budget in front of the finance lead and later show what moved, you need a baseline that can be repeated identically about 90 days on. An annual survey can play that role for perception; for load, it is the diagnostic's role.

The Canadian Centre for Occupational Health and Safety (CCOHS) suggests prioritizing the hazards found by their likelihood, impact and consequences, and notes that a workplace can focus on one or a few of them at a time and address more later. To sort that way you have to know which load is in question, and a reading by type of load allows it.

Can you run a survey and a diagnostic together?

Yes, and it is probably what you will need. According to the CCOHS, organizations will most likely need more than one assessment method to understand where improvements can be made.

Its list of common methods includes reviewing internal data such as complaints, absenteeism and turnover, and gathering feedback through conversations, observations, group discussions, anonymous forms and surveys. The CCOHS adds that using a variety of methods can help prevent survey fatigue, and that assessment activities should be paced reasonably for the workforce.

In practice, your survey becomes an input to the diagnostic rather than a rival to it: its results by unit tell you where to look, and the reading of load tells you what is happening there. When the two diverge, for example a steady perception in a function where load is concentrated, the gap is a finding in itself. Our post on spotting psychosocial hazards in a team shows where to look in a team's week before you commission anything.

Where do you start this month?

Write down, in one sentence, the decision you have to make and the question that comes before it. If you cannot word it, that is the first piece of work.

Then take stock of what you already hold: the results of your last survey by unit, turnover, absenteeism and recent departures. The CCOHS counts internal data among the methods it lists.

Choose one subject to look at more closely, then name who owns the response and the quarter it lands in. Finally, set the date of the second measurement, about 90 days out, before you begin. Without it you will not know whether the change helped.
