This document discusses portfolio analysis, which involves categorizing spending into four quadrants - leverage, strategic, routine, and bottleneck - based on the complexity of sourcing and relative spend amount. This helps determine the optimal sourcing strategy. For leverage items, the goal is optimizing buying power. For routine items, the focus is simplification and efficiency. Bottleneck items require managing risk through alternative sourcing or agreements. Strategic items aim to achieve competitive advantage through long-term collaborative relationships. Portfolio analysis ensures category management is proactive by matching strategies to spending categories.
