Project Summary: 1. Need a PPT done for the paper that I uploaded (10 slides). 2. Please answer all three (3) discussion questions. DQ3 is associated to your paper (paper that is uploaded); it asks about the metrics you intended to you to support your paper thesis. Use the concepts and terminology discussed in the book and in the chat session. Answer the discussion questions in at least 300 words with good content that clearly demonstrates your knowledge of the topic. Respond to student and instructor comments. DQ1 Define inventory and discuss why inventories are maintained. What are the four Inventory Models? DQ2 What is the difference between yield management and revenue management for service based organizations? How can service companies carry labor inventory? Could there be a just-in-time labor model? What would that organization look like? DQ3 What metrics will you use in your paper? Why? What do they show to support your thesis?
