2 ways to get better at guessing

Try out your guesses; write them down.

First way: try out guesses with small, reversible tests

Try out changes on a small scale—involving a few people for a short period of time—and in a way that’s easy to bail on.

Things tried out this way tend to be crappy or prototype-y. Good:

  • Use a piece of paper instead of a fancy app.
  • Make a spreadsheet instead of a report.
  • Draw a table and figures on the wall instead of a spreadsheet.
  • Do it manually today. Automate later.

Small: you need only enough work to figure out if your guess was any good. Don’t dump resources or spend time rushing towards dead ends.

Reversible: work this way to take the sting out of failure. Idea didn’t work? Stop and try the next one.

Test: once you can point to an initial success, gather resources and proceed with something more elaborate.

Second way: a logbook of guesses

Once you start testing your guesses, you’ll find that you make a lot of guesses, and run a lot of little tests. So keep a log. Write down:

  • Your guess,
  • What you thought might happen, and
  • What actually happened.
  • Was your test bigger or smaller than it needed to be?

Practice this and your guesses will improve over time.

Don’t take my word for it—try it in a small, reversible way, and see.

3-step method for learning anything

“See one, do one, teach one.” ← That’s the method.

First: See one

Watch how the task is done. Have somebody who knows what they’re doing show you how. Take notes. Ask questions. Notice the materials, tools, techniques used.

Second: Do one

Get some first-hand experience. Bring your expert along. They’ll speak up with encouragement or suggestions. Take your time and do it right. Figure out what makes it complicated—there’s always some damn thing.

Third: Teach one

Show somebody else how to do the task. You know how, and you know all the little things they’ll need to know or have on hand to get the job done. They’ll learn just by seeing you work.

You’re done!

This learning model originated 130 years ago, usually attributed to William Stewart Halsted’s surgery dept. at Johns Hopkins University. ‘See one, do one, teach one’ is still used in medical training. It works. In more recent decades, because we can’t have med students slinging a knife and ‘doing one’ on patients anymore, the model has been updated a bit. What happens in medicine today is more like ‘see many, do many with supervision, teach many.’ In other words, they’ve slowed the learning method down for patient safety, but not changed the progression in any basic way.

For knowledge work

Guess what? ‘See one, do one, teach one’ is a great fit for knowledge and service work, because there is so much tacit knowledge embedded within… all that little, vitally important stuff like (these are real examples):

It won’t let you pull the report unless you sort data by these headings, for some reason.
Even though form A is first, it’s easier to start with form C since that asks the same questions in a better order.
The Spanish language brochures are out of date, make sure you update this part first if you hand them out.
The position of the ‘save’ and ‘cancel’ buttons are reversed on this screen.

Try ‘see one, do one, teach one’ sometime. It’s so much better than sending everyone to training (boring) or throwing a grossly outdated playbook at new hires (inhumane, although you should still write a playbook and update it).

Apprenticeship is the method, and one’s peers are the experts. The trainer’s role then becomes that of matchmaker—finding a person ready to teach for each person ready to learn—and of opening a little space and time for learning to arise.

TL;DR:

  • See one, do one, teach one is a method to teach and learn complicated tasks.
  • It matches how people learn (by doing)…
  • …and transmits what’s important for doing the work (tacit knowledge).
  • You don’t need an elaborate training function to do it.
