For many organizations, the decision to invest in a new eCommerce platform is largely emotional. Often, during the decision-making process, the pre-game favorite is given preferential treatment, risks are downplayed, and the benefits of the new reality are hyped in an overly aggressive way — starting the day the new platform launches. By building a solid business case based on quantifiable metrics with realistic upsides, eBusiness leaders can set reasonable expectations, manage channel skeptics, and educate the management team, all while gaining the critical support needed for this key investment.
