Prioritizing target accounts to allocate account-based marketing (ABM) and sales resources must be given proper attention and analysis. By challenging the status quo on defined strategic accounts or refining sales-supplied lists with fact-based intelligence, ABM teams can effectively demonstrate marketing’s value to the organization. National Instruments (NI) is a good example of a company that allocated the right resources to the right accounts using a structured process that will facilitate ongoing improvements. In this case study, we describe how NI examined, identified, and communicated accounts to support with its ABM initiatives.
