The Agile Program Management (APM) Software Buyer's Guide from Planview is a comprehensive resource for executives, PMO leaders, and technology decision-makers who are scaling Agile practices across multiple teams, programs, and portfolios. The guide explains why traditional team-level Agile tools often fall short at the enterprise level, particularly when organizations need greater visibility into strategic alignment, funding, capacity, dependencies, and delivery risk across complex initiatives. It walks readers through the core capabilities required in an effective APM solution, including program and portfolio planning, real-time metrics and reporting, cross-team coordination, scenario modeling, governance, and integration with existing Agile and DevOps tools. In addition, the guide highlights common pitfalls in APM software selection, clarifies how to distinguish between lightweight Agile tooling and true enterprise-grade platforms, and provides practical evaluation criteria, checklists, and worksheets to support a structured buying process. Overall, the guide helps organizations understand how the right APM software can connect strategy to execution, improve predictability, and enable better decision-making as Agile delivery scales across the business.
