Become a Lean Expert in the Evaluation of the Current Condition

In this article I want to go through some tips on conducting a Lean evaluation for any process.
Introduction

"An expert is somebody who is more than fifty miles from home,has no responsibility for implementing the advice he gives, and shows slides"
Ed Meese |
I really like that quote. It always makes me laugh; which leads me to the main topic of this article:
"Become a Lean expert in evaluating the current condition"
I recently posted the following topic for discussion to a group of experienced Lean Practitioners:
"What are the top five things you look out for when you first walk through a process to evaluate the "current condition"? i.e. What is the "Lean" mental checklist that you use ?
The answers were both frank and interesting.
So, in this short article I want to take you through a broad mental checklist that you should find useful.
This valuable information will equip you with a focused list of questions to ask, and observations to make, as you set about evaluating a process for the first time.
This information will give you a solid framework of ideas that you can use for the evaluation of any process.
So without further ado here are eight areas that you can use as your own mental checklist.
As you walk through the process you should make some notes about each focus area. When you r eview these notes you will get an overall impression of the state of Lean in the process and the potential areas for improvement.
Area of Focus : 5S / Workplace Organisation
5s is a process and method for creating and maintaining an organized, clean and high performance workplace
In terms of Workplace Organisation the main thing we need to understand is the overall condition and implementation of 5s.The bad news is that if a place looks disorganised then it probably has lots of waste. The good news is that there will be a huge potential to make some dramatic improvements:
Potential Questions to Ask:
 |
Is there a 5S Policy for the Organisation/ Process ? |
 |
Has 5S training been successfully carried out in the area? |
Observations to Make:
 |
Has there been any attempt at 5S Implementation and what condition is it in? |
 |
Is everything clear, organized and clean ? |
 |
Are there any obvious unsafe conditions or safety hazards which have been accepted and ignored ? |
 |
Is the correct storage/ parts /consumables in place? |
Area of Focus: Visual Control
Visual information needs to be relevant, useful, and up to date.
When you walk through the area you need to get a sense of whether or not Visual Control has been adopted as a way of managing the overall process.
Potential Questions to Ask:
 |
Do you have any visual control boards? |
Observations to Make:
 |
Are there examples of obvious visual control and visual aids? |
 |
Can you see Key Performance Indicator information and metrics? |
 |
Is there a Continuous Improvement Board and is it up to date? |
 |
Can you understand the condition of the process within 30 seconds of observing it. |
 |
Are there any visual signals that can tell you if the process is currently delivering late or on time? |
Area of Focus : Standard Work
Standard Work can be defined as the best combination of people and equipment utilizing the minimum amount of labour, space, and inventory.
For a process to be truly 'Lean; then there needs to be strong vidence of the use of Standard Work i.e. 'The best known way of doing something". As you walk round you need to get a sense of whether Standard Work is alive and well or whether each person does things their own way!
Potential Questions to ask:
 |
Are there Standard Operating Procedures for this process? |
 |
How do you go about training someone to do this task? |
Observations to make:
-Is there obvious standard work in process ? -Is there repeatability on each process step ?
Area of Focus : Customer Demand and Takt Time/ Cycle Time
Takt Time is the required process rate needed to meet 'true' customer demand.
Potential Questions to ask:
 |
What is the bottle-neck that dictates the current beat rate of the process? |
 |
Can this bottle neck be "widened" and is it necessary? |
Observations to make:
 |
Is the process running to Takt / Cycle time ? |
 |
Is there a sense of a beat rate/rhythm and "pull" across departmentsIs ? |
Area of Focus : Waste
Waste is defind as anything that does not add value to the final product or service, in the eyes of the customer. The Seven Classic Wastes in any process are:
1. Defects 2. Over Production 3. Inventory 4. Over Processing 5. Motion 6. Waiting 7. Transportation
Potential Questions to ask:
 |
What are the main types of Waste in the current process? |
 |
Can you give me some examples? |
Observations to make:
Area of Focus : Layout/Flow
A well designed layout is key to creating flow ,which is one of the building blocks for any Lean System.
Potential Questions to ask
 |
How long has this Workplace layout been in place? |
 |
Why is the process laid out in this way? |
Observations to make:
 |
The general layout and the direction of flow
|
 |
The distance between process steps
|
 |
Location of support groups
|
 |
Is there a sense of flow? |
Area of Focus : Inventory
Lean processes should have mimimum inventory to help improve flow, reduce batch sizes (one piece) ,reduce the amount of space required and ultimately the cost of doing business
Potential Questions to ask:
 |
What is the total current inventory level? |
Observations to make:
 |
Is there excess Material/Information waiting to be processed? |
 |
Is there inventory between work stations? |
 |
Are there piles of unidentified product,work in process,rejects, and finished items |
Area of Focus : Lean Culture
Potential Questions to ask:
Observations to make:
In conclusion
Hopefully you can now create a mental check list from the preceeding information that will work for you. Happy Lean hunting !
Hope this helps.
