Perspective

Stop asking how long the course should be.

The most common question in learning design is often the least useful one. Before deciding whether a course should be five minutes or sixty, understand what people need to do differently when the experience is over.

“How long should the course be?”

It is one of the most common questions in learning and development. It is also usually the wrong place to start.

The length of a course tells us almost nothing about whether people will learn, remember, or perform differently afterward. A five-minute resource can solve a problem that a sixty-minute course cannot. A job aid might be more effective than a module. A scenario might be more valuable than twenty slides of information.

The question behind the question

When someone asks how long a course should be, they are often asking about effort, cost, timeline, or how much content needs to fit inside the experience.

Those are understandable questions. But they are not the first design questions. Before discussing duration, we should be asking what someone needs to be able to do when the experience is over.

Learning does not happen in minutes

One of the strangest habits in workplace learning is treating duration as evidence of value. Thirty minutes. Sixty minutes. Ninety minutes. As if learning outcomes scale automatically with seat time.

Length measures exposure. Performance measures impact. Those are not the same thing.

Start with the performance goal

Before discussing format, duration, modality, or technology, identify the desired outcome. What should people be able to do? What decisions should improve? What mistakes should decrease? What evidence would demonstrate success?

Key principle

Design the outcome first, then choose the smallest format that can produce it. Duration is a consequence of that decision — never the starting point.

Not every problem needs a course

Many workplace challenges are workflow problems, support problems, feedback problems, reinforcement problems, communication problems, or incentive problems.

When those conditions exist, extending the course usually extends the wrong solution. A longer course cannot compensate for missing support. Additional content rarely fixes a broken system.

The real goal

The goal is not to make shorter courses. The goal is not to make longer courses. The goal is to create the smallest effective solution that helps people perform successfully in the real world.
