  • Forrester caters to CIOs, business executives, marketing and sales leaders, CX professionals, and line-of-business managers.
  • IDC customers include IT directors, CIOs, LoB managers, marketing executives, and financial analysts.

  • Gartner provides straightforward templates conveying their structured methodology, though some users find Magic Quadrants overwhelming in scope. Their portal organizes vast amounts of research.
  • Forrester aims to package research insights into easily digestible models and frameworks. Their materials are more graphical and flowing versus rigid tables. The research hub makes finding content simple.
  • IDC has a no-frills interface allowing users to dive efficiently into market data. Some find their research reports text-heavy with a steeper learning curve to extract key insights. Recent portal upgrades improve searchability.
