How much due diligence should an acquiring organization undertake with respect to economies of scope? Conventional wisdom expressed by consultants, the business press, and educators often implies that acquirers cannot be too diligent, given the risks that acquisitions entail. For instance, Moeller and Brady (2014, p. 142) argue that "the 'knowledge is power' mantra could not be more appropriate than in describing the value of genuine due diligence." Accordingly, consultants have cast the pre-deal evaluation of economies of scope as "the prime hard key to deal success, one which can enhance the chance of success to 28 percent above average" (KPMG 1999). Consultants have also warned that 88 percent of corporate acquirers consider insufficient due diligence the most common reason for deal failure (The Storytellers and Mergermarket 2013). Accordingly, the business press advises that organizations undertaking corporate acquisitions be very skeptical about the target's asking price (Eccles et al. 1999) and prepare to refrain from a deal if that price exceeds the value diagnosed in careful due diligence (Cullinan et al. 2004). Likewise, the virtue of extensive due diligence is emphasized in business cases that introduce MBA students to best practices in M&A deal-making. For example, Cisco Systems Inc. is often held out as an exemplar that conducts far-reaching due diligence involving large cross-functional teams from human resources, manufacturing, engineering, and marketing (Singh et al. 2009). Academic research on corporate acquisitions has also advocated extensive due diligence of economies of scope: "Acquiring firm decision makers must have a clear vision of how synergy will be created in the combined firm… Such a vision is worked out through careful due diligence on the part of acquiring firm executives before a decision is made to proceed with the acquisition. Effective visions do not result from transactions that are completed quickly and without careful analyses" (Hitt et al. 2005, p.
