Hi, I have around 6 years of experience with an experience in BPO and as well as in IT company as a lead for global support and testing. Though i had completed my green belt in my previous organization but i don't have any kind of certificate to show the same. So can you please guide me and let me know, how useful it would be for me going for the Black Belt or Green Belt Training program ? How good the same will be able to help me in future ? Regards, Farooq Renumanu.
