Is It Time You Checked Your Assumptions?

When I was four years old I found a sparrow with a damaged wing in the garden. For a day or two my mother and I kept it in a box in our garage and fed it on bread soaked in milk. Then, one morning, it had disappeared. I asked my mum where it was and she told me it had flown away.

I was reminiscing with my mum about this story a couple of years ago when she turned to me and said, "But Stuart, the sparrow died. I had to put it in the bin."

Of course the sparrow had died. It could never have survived a broken wing. But for over 35 years I had never questioned the idea that it had simply got better and flown away.

I don't think that I am alone in failing to challenge some basic assumptions and wanting, unquestioningly, to believe the most attractive answer. Take these examples:

• The leaders of the world's major banks have carried a belief that they could remain fireproof to higher-risk loans, and have either not carried out or failed to understand their own risk assessments.
• According to Gary Hamel in his book, "The Future of Management", the US car industry has taken over twenty years to really understand the 'secret' of Toyota's success in North America, let alone respond to it.

We all hold onto certain assumptions that may or may not be true. But in these, more turbulent times, the rules of business can change radically and so must your assumptions -- even those you have never before explicitly questioned.

What are the assumptions that you are holding about your business that you haven't fully challenged?
