Organizations often assume routine work becomes lower risk simply because people perform it every day. The logic seems reasonable: repetition builds experience, experience builds skill, and skill should reduce mistakes.\
Experience does improve performance. But it also changes how people experience the work itself.
I saw this through two very different conversations about routine work.
The first was with a utility company. We were looking at a task that everyone described as basic, routine, and easy to do. Yet people kept getting hurt doing it, and that didn't make sense. So we mapped the work. What emerged looked nothing like the “simple” task people had described. There were critical decisions, changing conditions, communication between multiple people, verification steps, staffing considerations, and numerous moments where small differences completely changed what needed to happen next.
The work looked simple. But it wasn't.
A few months later, I was working with a group of experienced tankermen. Their job was to prepare a barge for product discharge, transfer the product, and then clean up. No one thought this work was simple. The operating procedures filled hundreds of pages. It took years to become fully qualified. Everyone in the room understood they were performing highly skilled, highly consequential work.
As we mapped the task together, something unexpected happened. The tankermen didn't all describe the work the same way. They didn't all perform it the same way. They agreed on the objective and the critical safety requirements. But the order they described, the cues they relied on, the adjustments they expected, and some of the decisions they made weren't identical. None of those differences were necessarily wrong. They reflected years of experience, adaptation, and personal judgment.
At first, these two conversations seemed completely unrelated. One organization underestimated the complexity of the work. The other fully respected it. Yet both were facing the same underlying challenge.
Familiarity Changes How We Experience Complexity
The utility workers thought the task was simple because familiarity had compressed their experience of its complexity. The tankermen knew the task was highly complex, but familiarity had changed how they navigated that complexity. Decisions that might have required considerable thought when they were learning the job had become part of how they simply did the work.
That's an important distinction: The task hasn't become simpler. Our experience of it has.
Experienced employees don't consciously encounter familiar work the same way a beginner does. They recognize patterns. They anticipate what comes next. They know which information matters. They make adjustments without necessarily stopping to think through every individual decision.
That's expertise. And most of the time, it works remarkably well. The challenge appears when the work people encounter today doesn't quite match the work they expect.
Familiar Work Doesn't Always Happen Under Familiar Conditions
The equipment changes. Materials get substituted. Tools get put down in different locations. Someone calls in sick. A contractor is unfamiliar with the site. The schedule gets compressed. Information is missing. Another crew is working nearby. Something breaks. The task itself may be familiar, but the conditions surrounding it often aren't.
That means experienced employees aren't simply executing a familiar sequence. They're also noticing differences, solving unexpected problems, coordinating with other people, interpreting new information, and deciding when the usual approach no longer fits.
Sometimes the differences are obvious. Often, they're subtle. A handoff happens slightly differently. Equipment responds in an unexpected way. A normal step occurs out of sequence. Someone assumes another person has completed a verification. The conditions are just different enough that the familiar response no longer quite fits.
And that's where familiarity creates an interesting challenge. The better we know a task, the stronger our expectations become about what we're going to see, what should happen next, and how the work normally unfolds.
Those expectations make us extraordinarily efficient. But they can also make small departures from the expected pattern harder to recognize.
Routine Doesn't Mean Low Risk
This is why I think organizations need to be careful about equating routine with simple or low risk. A task can be performed thousands of times and still depend on judgment. It can be highly standardized and still contain variability. It can be performed by extremely experienced people and still require them to recognize when today's situation is different from yesterday's.
The question isn't whether experienced employees know how to do the work. It's how familiarity changes the way they engage with the work when something changes.
Instead of asking, “How do we get people to pay attention more?” organizations can begin with a different question: How do we design routine work around the way experienced people actually think?
That's the question this series will explore. To answer it, we first need to understand how repetition changes the way people engage with familiar work.
Coming Up Next
I'll introduce the Productivity–Awareness Paradox: why the same process that makes experienced people faster and more efficient also changes how much of familiar work they consciously process.
