This is an easy way to identify market needs.
Draw a graph. Identify on each axis a selling point your competitors use. (An example could be price and quality.)
Start plotting which quadrant your competitors fall into.
If everyone is trying to be cheap, why don’t you consider being expensive?
If everyone is slow, why not be faster?
If everyone is going big, should you be small?
You can’t be cheap and expensive at the same time. Nor can you provide higher quality goods and be at the bottom with pricing.
You should be here, if everyone’s over there.
