This document provides an overview of lean manufacturing techniques for improving production processes. It discusses concepts like overall equipment effectiveness (OEE), theory of constraints, continuous flow, standardization, 5S, kanban, and waste analysis. Examples are provided to illustrate how to identify and reduce different types of waste in production. The document also includes a case study example of improving processes in a sandwich factory by implementing divisions of labor, standardizing cycle times, and establishing kanban systems.

Most treat production as a black-box but if you want to be a great
consultant you will have to get into details. In this chapter I will show you
how to improve production results and what it means in practice
▪ Produce as much as possible (maximize
throughput)
▪ High quality products (zero defect rule)
▪ With as little waste and inefficiency as possible
▪ At lowest possible operational cost
▪ As fast as possible

not add value
Due to different of waste we only use 5% to create value

In lean manufacturing We
have different types of
waste:
• Overproduction
• Defects
• Inventory
• Over-Processing
• Transport
• Motion
• Waiting
Share in total
%
13. 13
We will be using the following techniques to optimize the processes
Overproduction ▪ Overproduction is making too much or too early. This is usually because of working with oversize
batches, long lead times, poor supplier relations and a host of other reasons.
Defects ▪ You produce faulty things or not up to agreed standard. This may be due to errors done by production
people, quality issues or faulty materials
Transport ▪ Transport is the movement of materials, people, machines from one location to another. This is a waste
as it adds zero value to the product.
Waiting ▪ Long periods of no action due to lack of materials , resources, people
Motion ▪ Unnecessary motions of workers due to the way working space is organized
Inventory ▪ Too high inventory that cos t you money, space and causes operational problems
Over-Processing ▪ When you use the wrong tools, procedures or methods you are creating waste as well
You have not used the
employee’s creativity
▪ If you waste peoples’ efforts and creativity you will stop developing
Definition
14. 14
Below an example of identified in a retail chain waste
Too much movement (people,
resources, materials)
Lower the need to move
Move faster
Change the timing of the movements
Eliminate the movement
Peak of activities
Set priorities
Assign specific people to perform the activity
during peaks
Decrease the difference between high and
low periods
Use different frequency for different activity

In production you will know far less than the your customer’s team so you
have to use smart ways to get to the bottom of the things. 5 Why is one of
such methods
Why we are not selling more?
We are not able to produce
more
Why we are not able to
produce more?
Because we have reached our
production capacities
Why we have reached our

What is the throughput of every system and where
is the bottleneck?

Example 2

Example 3

x Stage capacity
23. 23
The are 4 rules that you should follow when it comes to
bottlenecks
▪ Identify what is the bottleneck
▪ Increase its throughput by lowering the time needed for
everything that goes through the bottleneck
▪ Add new resources to bottleneck
▪ Adjust everything to the bottleneck – so it works at the
same pace
25. 25
Ideally you would like to have a continuous flow of goods
▪ Each process “speaks” to each other and it is enough to
say to the last one what you want. The rest will follow
▪ Pull process not a push process
▪ We produce only what the customer needs and exactly
as much as he wants
▪ Hardly any inventory
▪ We use efficiently resources especially people
26. 26
In order to implement it in real life we have to define
some terms
Hourly capacity
▪ Number of semi-products / parts that can be
produced by a specific worker
Cycle Time (CT)
▪ Time in minutes needed to produce 1 semi
product /part by a specific worker
=
=
Hourly Capacity =
60
Cycle Time (CT)
Takt time
▪ Frequency with which the product is demanded
by the customer=
Cycle Time (CT) ≈ Takt time
27. 27
Continuous flow gives you a lot of advantages
Short cycle time
Less inventory
Higher quality
Fewer inefficiency
Better usage of people
Less space
Faster servicing of the
customer
Lower need for
transportation
Lower costs

36. 36
If we want to limit the waste we will have to look at the cycle time of
each and every operation. As you can see this is due to the fact that
some process are much faster than the things that follow after them.
You have to get even cycles

37. 37
The are number of ways in which you can try and get the
even cycle times
▪ Combine two operations
▪ Divide 1 operation into many
▪ Speed up the operation
▪ Put Kanban between the 2 process or FIFO lane and limit
the time of specific worker spend on the working station
38. 38
We know that customers want to eat 6 sandwiches during
the hour. It means that we need cycle time of 10 for every
process

You quite often have situation when people perform at
different pace and with different results. You have to
standardize them
1 2 3 4 5 6 7 8 9 10 11 12
49. 49
Standardization gives you a lot of advantages
Faster time of execution
Lower waste
Bigger predictability
Easier management of the
production floor
Easy to replace workers
Gathering of knowledge
50. 50
If you want to standardize the work I recommend the
following approach
Pick a process
you want to
standardize
Divide it into
small activities
Measure them
among many
executions
Find best
practices and
describe them
Implement
standard
(trainings,
procedures,
tools)

5S in short is about cleaning your working
station, putting everything in order and
keeping it this way
53. 53
5S consists of 5 stages
Sort
Set in order
ShineStandardize
Sustain
▪ Remove things that you do not
need
▪ Arrange essential items in such a
way that it is easy to access them
▪ Create set places for them
▪ Keep your working station, tool,
machines clean and keep the
order set
▪ No trash and dirt
▪ Establish rules, checklists
standards and procedures to
keep everything clean and in
order
▪ Turn 5S into habit
▪ Use visual language and
prompts to sustain the
habits
55. 55
Some signs that will show you that 5S is not implemented in
the factory
Machines are dirty
People leave their working
station without cleaning
A lot of unnecessary things just
lying around
Dust on tools
A lot of movement by workers
caused by number of things
surrounding him
No set places for tools and
materials
Everybody dress differently
No procedures / checklist / visual
controls
58. 58
Why it makes sense to get rid of unused things?
Slows down
Takes the place that can be
used by good things
Mental pressure
Distracts you
You lose track

Consulting is a place where the work is very volatile – one day
you work 15 hours and next day you have nothing to do. What
you want to do is use the time of low activity to somehow
prepare yourself and absorb periods of high activity

Therefore you should create a shelf of tasks to be done once
you are free. This to-dos should be properly selected and
structured and can have the form of a Kanban

In the case of machines you can measure Overall Equipment Efficiency.
Similar concept can be used to measure efficiency of people
91. 91
Similar to OEE that is designed for machines you can
define the Overall Labour Efficiency (OLE) for people
▪ Estimated for machines
▪ Shows you what percentage of
the machine is used to create
value for which you are paid by
the customer
▪ It makes sense to analyze it
especially for expensive
machines and bottlenecks
OEE
▪ Estimated for people

the people is used to create
value for which you are paid by

▪ It makes sense to analyze it

Before you start analyzing the waste you have to somehow group it by
stages of occurrence and type of waste
Type 1
Type 2
Type Z
Stage 1 Stage 2 Stage X….
….
94. 94
For finding the potential improvements in waste I propose the following
approach
Measure and
allocate waste by
stages and type of
waste
Pick specific type of
waste and the stage
you want to tackle
Find the root cause
Find the
improvement
Calculate whether it
makes economic
sense or not
95. 95
There are some standard reasons for high waste
Reasons for high waste
Faulty machines
Lack of procedures and
processes
Poor training
Lack of measurement
Change of technology
Lack of preventive
maintenance
Badly applied technology /
procedures
97. 97
Let’s start with the definition of a setup
▪ Setup is all activities required to switch
production from part/operation A to B
▪ Setup time is time between the last produced
part A to the first good part B
98. 98
When we look at any machine you will see that a lot of it’s
time is taken required set-ups

▪ Transportation of dies, blades and other parts
▪ Check and repair of dies, blades and other parts
▪ Tools collection
▪ Pre-heating of die
▪ Securing of raw materials
▪ Setting some operation conditions
▪ Attachment and removal of dies, blades, etc
▪ Centering, dimensioning, setting operation
conditions
▪ Trial processing attachments
Operations

Internal operations
External operations
▪ All operations that can be
performed while a
machine is in operation
▪ All operations that can be
conducted only when
machine is stopped*

There are some signs that the company has more or less
functioning TPM
They have predictive and
preventive maintenance
A lot of maintenance is done by
production
Machines are clean and taken
care of
Availability is high
There is low percentage of
quality problems due to
machines
113. 113
In more and more cases you have to find way to replace or support
people with machines to lower down production costs
Machines automating almost fully
specific actions
I.e. CNC
Transportation
I.e. Kiva – self driving robots that bring
the stock to you
Semi automatic solutions
Fully automated lines
114. 114
For automation analyses I propose the following
approach
Measure
current costs
Find automation
solution that
has similar
capabilities
Analyze the
payback time of
such a machine
Check how it
influence the
operations
If it makes sense
propose the
change
▪ Minimal batch
size
▪ Setup time
▪ Variability of
products that
can be
produced on
the machine /
line
▪ Maintenance
needed
▪ You may need
to switch the
whole line for
some time
▪ You may need
to build
additional
space
▪ Most new
machines /
lines are
underperformi
ng in the first
period

There are some clues that something is a good candidate
for automation
When you have
chances to make
big impact with
automation?
Demand for the product is erratic and
seasonal
A lot of people are involved
Long setups are needed to move from
product to product

One of the biggest problem for efficiency is the so called Parkinson’s Law –
Work expand so as to fill the time available for its completion

Why do you need to manage capacity?
Factories take time to build
Market leaders want to build ahead of
time capacity no to loose market share
Cash flow management
You may want to increase your
responsiveness
New capacity = New technology
New capacity may help you lower your
cost
Managing capacity means also closing
down some facilities
123. 123
When managing the capacity you will have to answer some questions
Managing capacity
What will be the operational impact of the
change in capacity?
When to create new capacity?
Where and what?
What capacities to close down?
125. 125
The right approach to capacity will differ depending on the
market characteristics
In the market Ahead of market (lead market) Follow the market (lag market)
▪You want to preserve your share
▪Building too early the capacity is too
costly and you do not see extra value
in it
▪Growth of the demand is pretty
predictable
▪There is some value in
responsiveness (you may get higher
prices for shorter lead time)
▪Demand is pretty difficult to properly
predict
▪You can use this tactic to increase
your share in the market
▪Keeping extra fee capacity is
expensive
▪Margins in the business are low
▪The market is experiencing slow grow
▪Demand is pretty difficult to properly
predict
126. 126
There are a few ways in which you can expand your capacities
What options you
have for capacity
increase
Subcontract some of the processes or
production
Squeeze more from current assets
Expand current facilities
Build new facilities
Buy existing facilities
