Which of the following actions is most closely related to a “Mature” level in the APM Maturity Model?

In the context of an APM Maturity Model, a "Mature" or "Optimized" level signifies a shift from reactive, project-based activities to a proactive, institutionalized process. Continuous improvement of the application landscape is the hallmark of this stage. It involves ongoing monitoring, regular portfolio reviews, and dynamic adjustments based on changing business needs and technology landscapes. This contrasts with lower maturity levels, which are characterized by initial inventory creation, manual analysis, and one-time rationalization efforts. A mature practice integrates APM into the organization's core strategic planning and governance cycles.

A. Automating decommissioning for all applications is impractical and risky; strategic, case-by-case decisions are a sign of maturity.
C. Relying on manual analyses is characteristic of lower maturity levels; mature organizations leverage automation and integrated data.
D. Identifying legacy applications is a foundational APM activity, typically accomplished at earlier stages of maturity.
