Six Sigma is philosophy to continuously improve the processes to achieve operational excellence. 8D or 8 disciplines of problem solving is a problem solving methodology that aims to improve output of a manufacturing process or design. Therefore, 8D can be considered as a Six-Sigma tool. Originally developed by the Ford Motor Company in the 1980s, 8D problem solving approaches have made inroads into the medical device development sector.
After graduating in Mechanical Engineering from IIT (BHU) Varanasi, India, I pursued a dual degree Master's program in Europe (MS in Biomedical Engineering at RWTH Aachen, Germany and MS in Bioengineering at Trinity College Dublin, Ireland). I am currently working as a 'Manufacturing Engineer' in a MedTech company in Ireland.
