Hi, I am a senior studying operations management and for my honors thesis I am trying give suggestions to my fathers friends blood bank to make it more lean. Do you guys have any suggestion as to what the first things I should do? I started already by doing a value stream map of the place which has given me a great insight as to how the place works but has not really given me much of improvement. I was also thinking of trying to do a 5s workshop with the employees any other suggestions would be greatly appreciated. thanks, B
