Respondents to Forrester’s 2021 Portfolio High-Performance Survey ranked messaging, content development, and launch as top portfolio marketing responsibilities. Although these activities are important, the responses don’t account for more strategic activities needed to fuel revenue growth. Given rapidly changing market and technology conditions, portfolio marketing leaders must redirect their teams’ emphasis, building capabilities to understand market dynamics, identify opportunities for growth, and prioritize go-to-market efforts. In this report, we set forth a vision for the portfolio marketing function, identify the challenges that portfolio marketers face, and highlight key future activities required for building a more strategic team.
