Will my experience in Sales and Marketing be relevant if I apply for Industrial Engineering?

I’m a Mechanical Engineering (Undergraduate) from India and I will have 18 months of work experience by Fall 2017. I work for one of the top lubricant manufacturing companies and handle B2B sales. Being a Techno-commercial professional, I touch wide range of Industrial applications during my work.

I would like to pursue MS in Industrial Engineering with a focus on Supply Chain Management. I’ve two parts in this discussion-

a) Will doing a Masters in IE add value to my profile in moving up the corporate ladder?
b) Will sales experience be recognized after completing Graduate degree?

Any insights would be highly appreciable.
