What is a "Burning Platform?" Definition or Meaning

This jargonistic term describes your business as on fire, and not in a good way! With everything about to go up in smoke, you’re faced with a burning platform, and you have to act very fast to save yourself.

For example…

Nokia is a business that was faced with a burning platform after taking a hammering from the sudden rise of the smartphone market. It was time for the company to make radical decisions in order to survive. It recently re-released a renewed version of its classic phone – perhaps a move it may not have made in different circumstances.
