CIOs and other tech decision-makers will have to navigate conflicting positive and negative forces on their firms' tech spending in 2016 and 2017. On one hand, adoption of cloud is spreading to the core of corporate systems, increasing software-as-a-service (SaaS) deals and related services spending. On the other hand, uncertainties about energy prices, overseas growth, interest rates and equity markets, and the US elections foster caution and reduced tech spending for hardware and licensed software. This report lays out Forrester's analysis of how these conflicting forces will play in US tech markets in 2016 and 2017 and how CIOs should position their firms' tech spending plans.
