A business develops useful beliefs about customers, channels and delivery. Over time, some of those beliefs can become treated as permanent facts. The risk is greatest when the old explanation still sounds sensible after the conditions have changed.

Name the inherited assumption
Choose a statement that influences decisions: customers need a physical visit, this channel produces the best leads, or buyers will not pay for this service separately. Ask when the belief was last tested and what evidence currently supports it.
Avoid using a famous company's decline as proof of a single cause. Business histories are complex. The practical lesson is to examine your own assumptions while there is still room to respond.
Look at the edge cases
Review customers who behave differently, emerging alternatives and workarounds the team dismisses as unusual. An exception is not automatically a trend, but repeated exceptions deserve attention.
Talk with people who are not invested in preserving the current explanation. Make disagreement useful by asking for evidence and a testable alternative.
Run a contained challenge
Test the assumption in a limited part of the business. Protect current commitments while learning whether a different model is viable. Give the experiment enough room to produce a meaningful result.
Update the operating reference
If the evidence changes, revise the process, training and decision criteria that depend on the old belief. A new insight has little effect when the organisation continues to reward and repeat the previous behaviour.
