This my Management Information System class and I have discussion I want answer those questions/steps.

Use this forum to discuss about Walmart and Amazon case  presented in Chapter 3. (I upload the topic). from the topic answer each question/step in one paragraph.

This the discussion question:

 “A case study analysis must not merely summarize the case.  It should identify key issues and problems, outline and assess alternative courses of action, and draw appropriate conclusions. The case study analysis can be broken down into the following steps: 

Identify the most important facts surrounding the case.

Identify the key issue or issues.

Specify alternative courses of action.

Evaluate each course of action.

Recommend the best course of action.”

 for each question/step one paragraph, so the total are five paragraphs.
