My Harvard colleague Thomas “Tom” Eisenmann, an entrepreneurship expert, finds that many start-up failures are caused by the skipping of basic homework. For example, Triangulate, an online dating start-up, rushed to launch fully functional offerings that didn’t fit any market needs. Eager to launch fast, founders skipped the research— customer interviews to probe for unmet needs. Giving short shrift to that crucial preparation, the company paid the price. Tom attributes this common failure, in part, to “the ‘fail fast’ mantra,” which overemphasizes action, shortchanging preparation. Moreover, while this might seem self-evident, once you’ve done the homework, you must heed what it’s telling you.
