I like Scott Galloway’s model to analyse a business..

1. Is it differentiated – does it offer value (actual or perceived) over and above similar products / services. What makes it stand out?
2. Is it relevant – is it desirable but also attainable by enough customers for the business to be viable? Ferraris are only attainable by a tiny percentage of consumers but it is significantly differentiated and therefore is profitable.
3. Is it sustainable – is the business model, and to a certain extent the balance between differentiation and relevance, stable or improving to ensure it can be maintained.

This can also apply to personal working styles, ideas, ways of working, organisational structures.

Am I different, am I accessible, am I authentic.
