Here are some more...
Lean Objectives foundational to your Vision and Values for lean continuous improvement
There is no such thing as 'cookie cutter' lean
You can't just "do over here what they did over there".
You can't just "hire someone who used to work at Toyota".
You can't just "buy some lean tools with online training", and then expect them to be used effectively.
(despite all of our efforts to try to come close to that ideal...)
Tools do not answer the question of "why", only the question of "how".
A guiding principle answers the question of "why".
When people understand why, they become empowered... to make good decisions.
~ Excerpts from the Shingo Model Handbook
Don't Reinvent
Why re-invent?
Yes, Lean Principle # 1 is "Every Lean Implementation is an Invention"
but that doesn't mean that you want to start from a state of ignorance.
and then... make them your own
As you continuously improve your own lean systems for your own unique organization and culture, make sure that your inventions always stay true to these 'True North' lean principles.
If people just backslide into old habits, then why even try to improve?
In a lean organization, every routine process has standard work, and every manager and leader (even the CEO) devotes a percentage of their day to Leader Standard Work.
What's so wrong with backsliding into old habits?
Lean culture is the sum of individuals' habits. Especially lean leadership habits.
Lean Management Systems are systematic ways to shape those habits.
Your management trusts your people. People are responsible for their own area - cleanliness, maintenance, organization… There is a flat organization structure with many self-directed teams. Everyone has continuous improvement responsibilities, and there are systems for daily coaching. Everyone understands the organization's strategic direction, and why their team's current Strategic Challenge is so important.
If your leaders have not yet established
job security,
then you do not have a Lean Culture.
Many MBA schools still teach 'Management By Objective' (MBO), which encourages managers to establish a goal, and then 'give your people the freedom' to reach that goal in their own creative way.
MBO is incompatible with Lean. If you're going to be a successful manager in a lean organization, then, yes, you will participate in choosing your team's next Strategic Challenge to support strategic direction, and yes, you will empower your people to come up with creative ways to make those goals happen, but you will be very interested and involved in the details of how they do it.
In a typical lean journey to lean transformation, people get their first exposure to their first lean tool or method because they are seeking to put out an urgent fire.
(Hopefully), they soon discover that the best ways to find and eliminate the 7 deadly types of waste almost always focus on lean flow.
Traditional organizations organize and manage in functional silos.
(Operations, Accounting, Maintenance, Purchasing, Engineering...)
Lean organizations organize and manage by focusing on the flow of value to the customer.
Value Stream Mapping
isn't even the most visible evidence of value stream management
If it's hidden, it can't be improved. One important lean principle is to use diverse tools and methods for Visual Management to make it as visible and obvious as possible — What is normal? Is there anything happening (real-time) that is abnormal?
Lean systems are designed using pull systems to quickly produce to actual customer demand.
(rather than building to a forecast of projected possible customer demand)
Every lean tool and system is a unique application of the Scientific Method of Problem Solving for different common challenges encountered on a typical lean journey.
Your lean objective
is throughput, not output
(Inventory that is sold,
not just produced)
Managers don't just dictatorially command their people to "think better".
They provide tools, systems, and one-on-one coaching for Hansei Lean Thinking. (Systems for how to think better)
When anyone identifies a quality problem, work is stopped, (so that no more defects are produced), and a team of people from many parts of the organization swarm to quickly identify and eliminate the root causes, and then to institute countermeasures to ensure that that never happens again.
Perhaps it might be worthwhile to evaluate whether Systems2win training and coaching services might prove useful for the highest-level coaches in your organization?
As you progress on your own lean journey toward lean transformation, you will discover additional lean objectives and ideals, but this is a pretty good list to bookmark and come back to... often.
Road map for a typical
Lean Transformation
That's why they're called ideals.
Their purpose is to provide 'True North' direction — toward which every member of your organization is commonly striving, and yet will never fully reach.
If your organization has a written Vision Statement, it will undoubtedly include most of the following lean objectives and ideals that are common to every lean organization.
And if your organization does not yet have a Vision Statement, then you might save some time and just get started with these...
All lean objectives
reduce or eliminate
the 7 types of waste
Manage to a Strategic Challenge
A Strategic Challenge is the link between PDCA and your Strategic Plan
Lean Principles and Ideals are too vague and distant to serve as useful guides for daily kaizen and PDCA Coaching Cycles.
Even your Strategic Plan or Annual Hoshin is too high-level to serve as a useful guide for daily process improvements.
A shorter-horizon 'Strategic Challenge' (established by your mid-level manager) provides a clear direction for what is needed from your team to support the other teams that will depend on you when you all reach the next resting place on your never-ending lean journey toward your never-changing lean principles.
Criteria for a Strategic Challenge
Your mid-level manager needs to come up with a Strategic Challenge for your Value Stream and/or Department that meets the following criteria.
1. A compelling description of a desirable state
A process breakthrough that will bring competitive advantage
Condensed to a compelling short rallying cry to focus the team's attention and effort.
Examples:
Wouldn't it be great if we could... | Rally Cry |
---|---|
make any item the same day that it's ordered, and ship the next day | Ship tomorrow |
get the results of any lab test back within 2 hours | Know today |
completely eliminate safety accidents | No accidents |
2. Far enough away to be a stretch
It can't be done with existing processes in their current conditions
3. Believable
Close enough to be within reach
(believably achievable within 3 to 30 months)
4. Clearly defined outcomes
Clearly defined measures and targets for process results that must (somehow) be achieved
The leader for each area of responsibility works with his or her coach
(at the next higher level)
to determine the capabilities needed from each value stream, value stream loop, department, process, and supporting function — in order to support the stretch goals of the next higher level
thereby uniting every effort at every level of the organization to pull together to support the highest level strategic plan.
5. Many options to reach those outcomes
Plenty of options for scientific experimentation for HOW to produce those desired outcomes
Puzzling enough that the details for how to reach those measures are not already obvious
If there is no 'unclear territory', then you have set your Strategic Targets too low
What's the point of conducting PDCA scientific experiments if you think you already know the answers?
How to choose your next Strategic Challenge
The most common way to identify potential strategic targets is to create Current State and Future State Value Stream Maps.
What does each value stream need to deliver?
What does each loop within each value stream need to deliver?
A "loop" is a section of a value stream
Start with Flow
As explained in our online training for What is a Lean Journey?
If you still have any value stream (or segment of a supporting value stream) that is not yet in a sustainable state of lean flow...
then there should be nothing strategic to think about.
The strategic challenge for that value stream (or segment) needs to start with Lean Flow
And you can't have Lean Flow without Standard Work.
Why is flow so important?

A frequently cited reference for Lean Principles is Jeffrey Liker's book, The Toyota Way.
When you search for 'Lean Principles' within The Lean Enterprise Institute, (lean.org), you will find their 5 Steps of Lean as well as an interesting article about early sources of lean principles (pre-dating Toyota).
Nothing.
It doesn't matter whether the process that you are improving is for lean healthcare, or lean office, lean service, or lean government...
Lean principles, objectives, and ideals remain the same.
In their paper Decoding the DNA of the Toyota Production System, Harvard Business Review, 1999, Steven Spear and H. Kent Bowen boiled down the essence of all lean systems to these Lean 4 Rules In Use:
Standardize work
No ambiguity
Organize for uninterrupted flow
Develop leaders who can apply the scientific method to improve anything
