A "good" market research report can cost you thousands of dollars. And when I say “good,” I mean a report that helped you make one of your difficult business decisions: should we buy company X, should we invest in industry Y, who are the competitors we should fear, who are the customers we should go after? While some may find it hard to determine to what extent, market research is unequivocally helpful when trying to make an affirmative decision (ie: should we enter this market?), and it can be equally helpful in informing on what to avoid.
Yet, often times, defining success when using market research can be a major gray area. Success doesn't always translate into definite measurables. Plus, success can be an extremely subjective concept. What a small entrepreneurial technology company might call success can be vastly different from success as defined by a Global 2000 corporate powerhouse.
