a company should work out the sector it belongs to. For economists,
the sector is a group of companies that create a market. According
to this, when we define the market that we want to belong to, we need
to make some limits, that's to say, where does the relavant market
(our market) end.
should study its sector and should ensure that they can mark the limits
to where they can compete, be it physically or in a productive capacity.
The company doesn't necessarily have to be concise in signalling its
limits in the sector or market, as a change in external conditions
could favour the company's strategy.
