The rise of software as a service (SaaS) and the explosion of cloud services has created a shift in how technology is being purchased, deployed and consumed at the enterprise level. Instead of technology procurement strictly being controlled by IT departments, decision-makers in finance, marketing, sales, HR, and other departments now act more independently. With little need for IT during the implementation phase, many business units freely choose and deploy SaaS solutions at will. This allows companies to easily take advantage of new technologies as they adapt to evolving market and business needs. While this model may keep IT from getting involved at the start, when performance issues emerge, these new technology buyers head straight to IT to fix it.
