Describing Operational Management

Write a One page Discussion with 2 externel sources (Make sure to do in-cite and cite the references at the end of page as well in APA 7th )
Operations is the internal “function” (i.e. department) of a business where value adding processes are managed. Combining Operations with Procurement (aka, Supply Management or Purchasing), Logistics and ERP systems (i.e., IS) allows companies to satisfy or even delight their customers. Some companies do this really well, leading to satisfied customers and repeat business. Some companies do this less well, leading to dissatisfied customers, negative social media comments, and lost business. Some companies seemed to have less trouble with this before Covid but are now embroiled in supply chain disruptions and not doing so well for their customers.
For your initial post: Describe at least one business experience that has satisfied you as a customer and at least one that has left you dissatisfied. Do you think the problem (or source of success) was with internal operations or supply chain practices? More generally, based on your experience, what should operations and/or supply chain managers do to delight their customers?
