What it does
Most business plans measure the market in the way that flatters them. One plan says there is no competition because it stacked five qualifiers. Another says it needs only a small piece of a market worth billions. Both can be wrong about the market a buyer actually sees. This skill puts the same business on a ladder of four markets, from narrowest to widest, and works out your share of each. Then it asks what a buyer picks when they say no to you. That set is the market that counts.
You give it
- What you sell and who buys it
- Your customer or sales numbers, if you have them (optional)
- What buyers pick when they say no (optional)
- Plan (optional)
- A shortlist (optional)
