Making a Case for ABC Inventory Control Process

I've been tasked with drafting a plan to pitch to Sam's Club and why they should use the ABC process. 

The pitch should:

• provide an overview of the process,
• explain why it would be an effective solution for the company,
• acknowledge any limitations,
• outline steps for adoption, and
• recommend the best practices for using it. (Written in a format appropriate for a business setting.)finding a better method of forecasting and planning for success. 

They have requested it to be formatted for a business context that includes the details of why this pitch would be appropriate.
