For the modern enterprise, services done well often drive growth. For example, quality IT infrastructure services and/or outsourced marketing can accelerate a company's competitive advantage in multiple ways. Although it's sometimes hard to measure the specific outcomes that services yield, they can have a major impact on a company's results, such as with more successful marketing campaigns, digital transformations, legal wins or other organizational efforts. That's why, in recent years, many Fortune 100 companies have significantly increased spend on service providers to meet competitive, productivity and business velocity demands. Companies can't hire and cultivate enough internal expertise as the work gets more sophisticated and specialized and the opportunities more global.
