Today I came across an interesting article, "Six Lean Principles for an Industry 4.0 World" Mar 1, 2019, by Mark Crawford in https://www.asme.org/topics-resources/content/six-new-lean-principles-industry-40-world
The article reports the views expressed by Jim Morgan, senior advisor for product and process development with the Lean Enterprise Institute. According to Morgan, lean is still about creating exceptional value for the customer (with minimum resources - no muda), but what is new is the growth in understanding of how to apply lean principles, tools, and practices in new ways in the new technology age.
The six new principles of focus concepts are given as
1. Gemba (Includes principle of perfection or continuous improvement)
2. Obeya (Cross functional teams for design - we may think of control tower of industry 4.0 systems)
3. Lean Process and Product Development (LPPD) (Includes earlier lean principles of value, value stream, flow and pull)
6 LPPD Guiding Principles https://www.lean.org/the-lean-post/articles/lean-product-process-development-guiding-principles-at-a-glance/
Designing entire value stream; that is, every step required to deliver value to your customer – instead of your product in isolation – is the defining characteristic of LPPD. - Jim Morgan, Lean Enterprise Institute.
4. Cellular Manufacturing or Flow Manufacturing (includes principle of flow and pull)
5. 5S
6. Poka Yoke

The lean principles given by Womack and Jones.
1. Value - F.W. Taylor said, Determine what needs to be done?
2. Value Stream - Process Chart
3. Flow - This is a new emphasis in lean - already in practice through group technology cells
4. Pull - is a new emphasis. Produce as much as possible in response to customer demand even internally within the organization. Like MRP innovation for dependent demand parts, pull principle insists on reducing lead time for internal production and producing as per actuall demand requirement.
5. Perfection - Continuous Improvement - Industrial Engineering (periodic studies and improvement) - Active employee suggestion schemes, improvement circles, shop floor improvement activity.
ASME is the birthplace of scientific management and industrial engineering. It is also the organization that gave us the process chart, the main approach for process improvement.
While value stream mapping is given lot of promotion during the recent years, process chart method is the more comprehensive approach and value stream mapping is to be a part of details of process method. This direction is indicated by Womack and Jones in their book "Lean Thinking."
Lean Thinkers have to use Industrial Engineering Tools - especially process charts. [VSM] analysis is at a high level, without many details. To uncover every instance of every type of muda requires a detailed analysis using a portfolio of tools drawn from industrial engineering ... The most important of these are process mapping (to identify and categorize each step together with the time, distance and effort involved)... Womack and Jones, 1996.
