In the future i want to run my own company at a global level which will require expertise in digital marketing, supply chain or coming up with some innovative ways to distribute the products. I am already working as distribution manager in our family based company and having experience of 8 years. I got an offer from Glasgow (10k scholarship), Birmingham and Strathclyde for MBA but was thinking to join some MSc from top b school like Imperial college for MSc in Innovation and Entrepreneurship. However, I was wondering will I be too mature to undertake MSc courses? If i choose to do MBA which b school would be better for my future?

I don't think there is a clear answer to think without a careful evaluation of what you know and need to know, when and what this new business will be, and what contacts you need. Probably an MSc from a top school and then an executive MBA ten-years later will be a good combination. 

I am already into distribution of smartphones which deliver products to assigned dealers in New Delhi and responsible of making their bundle offers to increase sales volume.
I am planning to run my own company which will sell customise phone cases and will follow very trending way of distributing it to expand its reach. After Master's, I would like to first work in a company for at-least 1 year who is already into same business to gain expertise. Then I will start working on my company. 

So now what you think will be an appropriate course according to my profile and future goals? Does doing an MBA now, will support me ? Which B-school should I target for September intake 2022?

In which business function (finance, sales, marketing, supply chain etc) would you like to work after your masters? Probably an entrepreneurship degree suits people who want to work for themselves. 

It will be a blend of marketing and supply chain, yeah I will be working for myself.
MSc in Entrepreneurship and Innovation will be a good choice ? Don't you this MSc course is meant for fresh graduates or with little work experience?

An MSc in entrepreneurship won't be a good choice if you a looking for work, because employers want, generally, people to work in a business function rather than to autonomously create a new business. A MiM is aimed at fresh graduates. An MSc in marketing or in supply chain/logistics/operations will have slightly older average ages than a MiM, and the highest ages will be much higher. I did an MSc in business analysis, for example, and the average age was in the mid 20s. I was 30, and not the oldest.

Thanks for your valuable feedback. Even I am 30 now, from your point of view doing an MSc in Marketing or supply chain will have good impact on my profile and can implement that skills for my future goals. Is that correct? What you think if i do MBA from uni of Glasgow?

You will be more likely to find work after an MSc from a top business school than from the Glasgow MBA  

Alright will try to look options for MSc. Do you have any suggestions like which b schools should I target for MSc?

Focus on the UK and Irish universities higher on the FT European Business Schools ranking that offer MSc degrees in your target business functions. That might mean 
- Marketing: Imperial, Warwick, Lancaster, Cranfield see https://www.best-masters.com/ranking-master-in-united-kingdom.html 
- Operations: Imperial, Manchester, Cranfield: https://find-mba.com/board/consultants/msc-supply-chain-cranfield-school-of-management-vs-aston-mba-in-operations-68602  

Thank you so much for your guidance.
