Further more, the actual utilization and value of six sigma certification is only if you are doing it through an organization, i mean lets assume that you are working with one MNC and they send you on a lean program now once you are done with the training your organizations lean expert will assign you a project and usually the certification is awarded once you are done with your project and have produced some outcomes. Other wise doing it from some xyz institute or expert will not add substantial value.
