The other day, I was thinking about the scene in the movie where Navin R. Johnson (Martin’s character) was working at a gas station and somebody was shooting at him, missing and hitting cans of oil (warning: a few PG-13 words):
This is all tongue-in-cheek, but let’s analyze his problem solving.
First, Navin discovers a problem. “Something’s wrong with these cans.” He gets credit for not jumping to a root cause.
He might have been thinking about the way I was taught by Pascal Dennis to define a “problem:”
- What Should Be Happening? Cans hold the oil inside
- What’s Actually Happening? There are holes in two cans, suddenly
- What’s the Gap? Two holes
- What’s the Impact? Oil is spilling out
Navin can’t hear the crazy man who’s shooting at him and two more cans spring leaks:
Navin yells to the owner of the station, “These cans are defective… they’re springing leaks!”
He’s made a faulty assumption that the cause of the holes is “defective cans.” He’s getting off track in terms of finding a countermeasure.
The owner, played by the legendary Jackie Mason, sees the shooter up on the hill.
He corrects Navin and says “we don’t have defective cans… we’ve got a defective person out there!”
More cans get hit.
So, Navin has understood a cause of the cans springing leaks. Asking why…
- Why is oil spilling out? Because there are holes
- Why are there holes? Because a man is shooting them
- Why is he shooting them? “He hates these cans!”
Navin has made a bad assumption here. The shooter hates Navin (for representing a completely average person, it seems).
Navin proposes a countermeasure that might not work… he yells, “Stay away from these cans!”
Navin runs away from the oil cans… to test his countermeasure in practice (we never know if a change is really an improvement until we test it out).
He runs to a Coke machine and realizes “there’s cans in there too!”
So he modifies his countermeasure a bit (a small PDSA cycle?) by running away from the Coke machine.
He runs inside the building… more oil cans!
Navin takes action again… by clearing away the cans (making it, unfortunately, easier to shoot him?)
Maybe this illustrates how we might panic when trying to problem solve in a stressful situation. Sometimes, we have to contain the situation, putting the proverbial fire out, before we figure out the root cause and longer-term countermeasures.
The station owner coaches Navin by yelling, “He doesn’t want to put holes in the cans, he wants to put holes in you.”
Maybe it’s idea for a coach to lead by asking questions. But, again, sometimes when you’re just trying to contain a problem, you might have to be more directive as a manager.
Armed with his better understanding, Navin tries a new countermeasure… driving off in a car. But, there’s a defect in the process, as the car doesn’t have its tires installed and he’s driving on the wheels.
Navin manages to drive off and escapes to a carnival.
Unless most ineffective warning signs, the shooter is actually deterred by a sign that says “Carnival Personnel Only.”
What’s the moral of the story? You can be a bad problem solver, but sometimes, with a coach (even a directive one), things can turn out OK. Hmmm…. I’m not sure about that lesson…
