The document identifies the key market trend driving the need for integrated Spend Management solutions:

"The key market trend driving the need for integrated Spend Management solutions is:

D. Emphasis on visibility into spending patterns

Why D is correct:

A major pain point today is the lack of visibility into spend data, leading to inefficiencies, higher costs, and strategic blind spots. Organizations require a unified view of spend across categories to improve decision-making, compliance, and resilience. Integrated Source-to-Pay platforms deliver comprehensive, real-time spend visibility, empowering teams to spot trends, uncover savings, and address financial risks proactively."

Why the other options are incorrect:

A. Increased reliance on manual procurement:"This is a problem, not a trend that boosts integration demand."

B. Decreased focus on sustainability:"On the contrary, sustainability is gaining importance."

C. A shift toward AI-driven tools:"AI is a technology enabler, but the core market driver remains the critical need for transparent spend visibility."

The document concludes, "Greater spend visibility is the primary market driver behind the growing demand for integrated Spend Management—making D the clear correct answer."
