Which is better : MBA, Master in supply chain or MCIPS?

It depends on your career objectives and targets.
MBA focus on commercial issues of whole businesses, it is a master degree of Business Administration.
MBA programs does not focus on Supply Chain.
Master in Supply focus on Supply Chain Managemet activities.
MCIPS stands for Member of the Chartered Institute of Purchasing and Supply.
By Member this means a fully qualified Member.
Full Members are recognised internationally for their professional accomplishment and one of the most prestigious a professional purchaser can achive.
In short, if you will focus your career on purchasing go for MCIPS, if you will focus career on Supply Chain a Master in Supply will be helpful, otherwise if you are not sure about your career or you do not want to focus on Supply entirely you need to go for a MBA program.
