Commercial due dilligence may depend on the industry as many times basic information exists either from the market or from associations of the industry.
But I believe that for a deeper level of information you need to conduct the DD in order to be certain that what you know is correct e.g. market share of an existing product line, customers data, price lists and potential terms to uncover and also a commercial due dilligence is a good opportunity to form an opinion based in facts from the commercial organisation of the target ie Commercial managers, sales force who at an advanced stage of the deal may be willing to disclose practices that you would never be able to find out before.
I would never rely only on stratgic advisors…my own view and deep understanding of the market is a must.
