Suppliers providing bottleneck and strategic items are most suited for regular business reviews because these items typically have high impact on the company's operations and can involve higher risks. Bottleneck items are critical components that can cause significant disruptions if not managed properly, and strategic items are essential for the company's competitive advantage. Regular reviews with these suppliers ensure better alignment, risk mitigation, and strategic collaboration.
