When answering complicated questions (i.e. strategy consulting) you can't boil the ocean and do everything at once! Therefore, you have todetermine:
First - Is the market as whole attractive?
Is it big? Growing? Do companies have healthy margins? Are there no price wars going on?
Second - Can we win in the market?
Is our product, in the eyes of the customer, better than that of the competition? If we enter, we better than the competition?
Third - Operationally/Executionally, what actually happens?
How to we enter (your question)? Which strategy will meet our objectives the best? Can we actually pull it off (do we have the money, prior expertise, environment knowledge/understanding, etc.)?
^The Third point is your point. You're right, you're just too early!
