TIME: The single best indicator
of competitiveness
Customer Lead Time / Delivery Time
Working to reduce or minimize each of these times can
make your company more valuable to both its internal
and external customers
Set-up or Change-over Time
Product Development Time
Manufacturing Cycle Time
Trang 3Shrinking Lead Times

Manufacturing Lead Times
Order Lead Times Delivery Lead Times
Reducing the overall time from receiving the order to delivering the product makes your company more responsive to the customer This can become the deciding factor when the customer makes
their selection
As can be seen, manufacturing is only one part of the entire
process Inputting, processing, and issuing orders is an area
for improvement, as well as, assembly, loading and delivery
to the customer`

Where’s the Time in Lead Time
This timeline represents an overall lead-time, with very little
time spent on adding value to the product
Non-Value Added Time (NVA) 99% of Total Lead time
Value Added Time (VA)
1%
Improvement Efforts Concentrated on reducing VA time, with no attention given to NVA
Non-Value Added Time (NVA) 99% of Total Lead time
VA 1/2 %
Results of Common Improvement efforts, did not improve
response time VA time is reduced, but, the costs for those
improvements in lead time was substantial
Common
Trang 5Where’s the Time in Lead Time
NVA Time
95% of Total Lead time
VA 5%
When we look at attacking the NVA Activities in the Timeline and compare that to the original timeline:
Non-Value Added Time (NVA)
99% of Total Lead time
Value Added Time (VA)
Trang 6Kaizen Training
Different Types of Activities
Being able to tell the difference between NVA and VA
activities is an important step in the Improvement Process.
Value Added Activity (VA)
An activity that changes raw material to meet customer expectations
Non Value Added Activity (NVA)
Those activities that take time, or occupy space but
do not add to the value of the product
You must ask yourselves “Would you as a customer be
willing to pay for any NVA activity being performed to that
NEW 4x4 Pickup you just ordered?”
Trang 7Some examples NVA Activities:
machine cycle
Transporting parts
Generating useless reports
THE GOAL IS TO ELIMINATE THE
NON-VALUE ADDED ACTIVITIES.
Unnecessary motion
Unnecessary stock on hand
Trang 8A definition:
Destroy, in our minds, the concepts and techniques of manufacturing that we
practice today.
Create a vision of what our production system and
manufacturing techniques should be.
Carry out that Vision by breaking through the status quo.
We must avoid the urge to
discover more sophisticated and
technological solutions to tasks
we shouldn’t be doing at all.
Trang 9Basic Rules for Change
Keep an open mind to change
No such thing as a dumb question or idea
Avoid spending money (Capital expense should
be a last resort)
Think about how to do it, NOT why it can’t be done
Maintain a positive attitude
Don’t’ make excuses & question current practices
Just do it!!
Have Fun!!!

Steps on Team Development
Forming This is the development of a multi-functional
team with a variation of backgrounds and knowledge
Norming Stage where the group agrees how to
operate as a team
Storming Open & honest discussion, also brainstorming
Performing Agreement on solutions & taking action
Adjourning Closing on the continuos improvement process
after 30 days
Trang 11What is TAKT Time?
TAKT time is how many minutes or seconds are needed
to make one part when considering the daily volumes, to
be produced in that workcell and the total time available to perform the job.
TAKT time is NOT the time it takes to manufacture the
product It is based on customer demand.
Who is the customer?
The next operation Customer orders

TAKT Time Calculation
Production Time Available / Period
Number of Required Units / Period TAKT
Production Time Available / Period (one shift):
Breaks - 2 @ 10 minutes
Shift Time ( 8 hrs )
Clean-up at end of shift
Production Time Available:
- 20 mins
480 mins
- 5 mins
455 mins
Units Required / Period (one shift):
10,500 Units Sold Monthly
21 Working shifts / month
27,300 secs
or
500 Required units / shift
TAKT Time: 27,300 secs / shift 500 units / shift 54.6 secs.
Trang 13The 5S Housekeeping Standards
First Step towards Continuos Improvement
The aim of 5S is to create an atmosphere to keep a clean,
organized, safe and efficient workplace for everyone
The foundation for the practice of 5S, comes from a Japanese
program derived from these words, seiri, seiton, seiso, seiketsu
and shitsuke The 5S’s are a conventional approach towards
maintaining and improving the work place The following words have been chosen for the 5S acronym’s
Sort
Sustain
Sanitize (Safety) Straighten
Sweep
Trang 14Kaizen Training
Meaning of the 5S’s
Sort Straighten
Sweeping, scrubbing and cleaning of the building, machines, fixtures & tools so that all areas of the workplace are neat & tidy This leads to early detection of mechanical problems before they become major breakdowns Machines cry!
Trang 15performance of their assigned tasks.
Developing the practice necessary to continually participate in the 5S process This requires that each of the S’s become a personal habit This is the most difficult of the 5S’s, but it
is the most important factor in achieving long term success Establishing routines and
procedures for maintaining and improving on the first four (S’s), incorporating visual
management tools

Trang 191 Transportation - Transporting 1 Transportation - Carrying

temporarily locating, filing,
stacking and moving parts
(people, paper, information) is
waste.

3 Overproduction - Generating 3 Overproduction - Number of
excess paper or information, or Copies
generating information or paper
too soon in a process is waste
Definition Example
Trang 204 Motion - Unnecessary work 4 Motion - Tools in drawers
movements are a form of waste.
5 Waiting - Waiting for people, 5 Waiting - Meetings to start
paper and information is waste -
it stops work.
6 Inventory - Too much of 6 Inventory - Supplies
anything is waste.
7 Processing - this is waste in 7 Processing - Typed when
the process itself Redundant handwritten would be

Standardize
• Process requires ongoing inspection and enforcement to
ensure “Standardized Work” is being followed
• Process does not improve automatically
- Following standards will only maintain, not improve, the
process.
- Improvement focuses on the entire process.
