What is the difference among an APS, a CRM, and an ERP system?

 I’m working on a writing discussion question and need an explanation and answer to help me learn.

This week, we explore three systems used by supply chain managers to run their supply chains operations.

Each of these three options is very successful in what they do for a company’s supply chains.

You have two actions in this discussion. First is to examine the three types of systems.

Second, you select one. Oh, there is no wrong selection. You use your opinion and expertise and familiarity with processing large amounts of data, or dreaming of such, if you have not been involved in this activity so far.

Then answer these two questions in your opening:

1. What is the difference among an APS, a CRM, and an ERP system?

2. Which of the three would be most beneficial to a retailer who could not afford all three?

You can use the source from class and go on the Internet to see what other key facts are out there.
