The most important high$-$level conclusion on the current state of sourcing indirect materials and services, as outlined in the article, is the "Neglect of indirect spend compared to direct materials spend." This is a critical issue because it highlights a significant gap in attention and resources allocated to indirect procurement. While direct spend on raw materials often receives substantial focus, the neglect of indirect spend suggests a lack of strategic consideration for a category that, despite being labeled as "pocket change," can represent substantial sums, potentially in the millions to billions of dollars. Addressing this neglect is crucial for organizations to unlock the full potential of strategic sourcing and gain a competitive advantage in managing their entire procurement portfolio effectively. could you reword this as a collge studnet wrting it
