Well, maybe you haven't tried "disruptive thinking." It's an innovative way to challenge your assumptions and conventional thinking.
One of the examples in this article by Luke Williams, author of DISRUPT: Think the Unthinkable to Spark Transformation in Your Business, is Little Miss Matched, a company that sells socks that don't match. The firm didn't address a problem so much as it challenged an industry in which everyone seemed to be stuck.
Your goal, says Williams, is to look for the clichés about your situation, come up with a disruptive hypothesis and then determine what you can invert or deny.
The whole point of the article, "inverting or denying industry clichés can often lead to significant business breakthroughs."
