How do you know if you have a great business idea?

Before starting a business, most people wonder if they have a good idea. ‘Good’ is an ambiguous term. It comes laden with assumptions – which could be different from person to person. So I thought I would elaborate on what, for me, a good business idea entails.

‘I’ve got a great business idea – can I sell it?’

“How do I sell my business idea? I have a great business idea but I want to sell it to someone rather than build a business myself” –
Sorry to dampen your enthusiasm, but this is not the way things work. Ideas are nearly worthless. It’s execution that creates value. People don’t buy ideas – they buy income streams.
