Flow is a lot more interesting than batch.
This occured to me in recent conversations with one of our team leaders who schedules work for her area. A series of well-intended but misdirected steps had created a batch process in her area. She couldn't figure out how to fix it but we managed to reverse the errors well enough and regain flow. Two weeks later, she couldn't be more pleased.
"We are getting more done each day," she beamed. Why? I asked. "Well, there is more variety. We work on several different products each day and that stops boredom. Plus, by doing that we use different materials and are less likely to run out of our supplies."
There is all the theory of why flow trumps batch, why synchronizing production to sales works, why pull is better than push, why reacting promptly is better than predicting accurately.
Yet, when you get down to the core, it's also just a lot more interesting.
