Where we teach this concept:
Here's an uncomfortable truth: many improvement projects fail not because of poor execution, but because they solved the wrong problem. Organizations waste countless hours addressing symptoms while root causes remain untouched.
Consider this famous example: In 1985, Coca-Cola launched "New Coke" to solve what they defined as a "taste preference problem". Their largest competitor, Pepsi, was winning blind taste tests. Coke invested millions in their new recipe and marketing. The product failed spectacularly. Why? Coke had solved the wrong problem. Customers valued the emotional connection and tradition of original Coke. By defining the problem as a “taste preference problem”, they missed what truly mattered to their customers.
A well-crafted problem statement has TWO essential qualities – it articulates the GAP between what should be happening and what is happening and it quantifies the IMPACT. So, how to get it right?
A good problem statement is:
*Notice how this helps identify potential causes and creates urgency.
*This defines success clearly and prevents scope creep.
See the difference? The strong version gives you:
A clear, quantified metric (processing time: 7 days vs. 3 days target)
Lean practitioners are trained to facilitate problem definition sessions with stakeholders, ensuring everyone agrees on what problem you're solving before jumping to solutions. This single skill prevents more wasted effort than perhaps any other Lean tool. It’s often said that spending an hour on the problem statement will save the team 10 or more hours in the analysis phase of an improvement project.
Take a problem you're currently facing at work. Write it down as you'd naturally describe it. Then, rewrite it using all five elements provided. See if your path forward becomes more clear.
The best part of a great problem statement? Once you've defined the problem well, the solution often seems obvious.
