Lean pdca cycle

Identifying what creates value and eliminate all other activities, as they are by definition ‘waste’, will become your normal approach to evaluating procedures and processes across every aspect of your enterprise. When you recognise that within your organisation only a fraction of the time consumed, and a small portion of all efforts undertaken, genuinely add value for your end customer, you will have a basis to clearly define true value from your end customer’s perspective. Only then can all your non value activities (or waste) be targeted for systematic reduction and eventual removal.

Waste reduction directly correlates with reduced energy consumption and carbon generation. Indeed, IBM asserts that IT and energy costs can account for up to 60% of an organization's capital expenditures and 75% of operational expenditures. [26] In this way, identification and streamlining of IT value streams supports the measurement and improvement of carbon footprints and other green metrics. [27] For instance, implementation of Lean IT initiatives is likely to save energy through adoption of virtualization technology and data center consolidation. [28] [29]

With the utmost respect to you and your work I cannot understand why people still want to promote PDCA when in fact DMAIC is a much more well balanced, logical, easier to teach, easier to follow methodology. You admit yourself that the work ‘Plan’ is too generic a word. Are we not ‘Planning’ and ‘Refining the plan’ all the way through a project ? You will recognize that ‘Plan’ is an activity the is only one activity recognised the PMBOK of the Project Management Institute, started in the ‘Initiate’ phase. The project plan is constantly being updated. In fact ‘Define’ is a what we are trying to do as a first step in any project. Define the problem we are trying to solve. Define the stakeholders. Define the project team. Define the scope. Define a high level plan.
The next biggest issue I have with PDCA is that the word ‘Do’ and the word ‘Act’ are so similar in meaning. Why do we have One Quarter of the Methodology ( 1 letter out of 4 ) describing the activity of moving onto the next thing ? Would not the word ‘Close’ be better ? Do we really need to take up 25% of the letters for this step ? In DMAIC the word ‘Control’ is a far better description of the post-Implementation step. I believe the Walter Shewhart and W. Edwards Deming would both agree that DMAIC is a better description of what we really need to be doing in a Process Improvement project.
Can you really defend PDCA when it goes up against DMAIC ? I would be interested to hear how you do that ? Thank you.
