Strategic sourcing is a procurement approach that involves analyzing an organization's spending habits and identifying opportunities to reduce costs, improve quality, and increase efficiency. Teresa Thompson, a renowned expert in procurement and supply chain management, has written extensively on the topic of strategic sourcing.

Unfortunately, I couldn't find a free PDF download of Teresa Thompson's report on strategic sourcing. However, you can try searching for her publications on academic databases such as ResearchGate, Academia.edu, or Google Scholar.
