2. Lean
• Philosophy and Practice of
Eliminating Waste and
Increasing Customer Value
Principle Apply to Every Function /
Activity
3. Lean
WASTE
• Activity or Output Adds Cost
but Does Not
Add Value as Perceived
by the End-Use Customer
4. Providing ‘Value to the Customer’
(Lean thinking focuses primarily on customer)
1) Lean Operations: Value and waste
2) Lean Methodology: Checks for value and waste
Difference between:
Adding Value to a) Product / Service
b) Customer
E.g. Customer prefer a simple ‘Masala Dosa’
(value to the customer) with good taste
at XXX Restaurant
But no value to the customer, if we
add Cheddar cheese over Masala Dosa
or thin silver wafer or gold plating.
All the above ingredients may add value to the product, not to
the customer (Value Visualization)
5. Lean Production
•“Uses less of everything compared with
mass production (John Krafcik)
• half human effort in factory;
• half manufacturing space;
• half investment in tools,
• half engineering hours to develop a new product
in half time.
15. Steps to Achieve Lean
Systems
• Design a Simple Manufacturing System
• Recognize room for improvement
• Continuously improve lean
manufacturing system design
16. 1. Overproduction – Too much, too early or just in case.
2. Waiting – Materials or information are waiting to produce
to next process and not moving or having value added
3. Transporting – Materials (or information) transported into,
out of or around factory and transport cannot be fully
eliminated, but aim is to minimize it.
Seven (7) Waste
17. 4. Inappropriate processing – Using machinery or equipment
is inappropriate in terms of ‘capacity’ to perform an
operation.
5. Unnecessary inventory – Ties up capital & space and
prevents identification of problems
6. Defects – Product defects, rework defects, scrap defects
or service defects.
7. Unnecessary motion – Ergonomics of the work place.
18. Seven Waste in Production
• Defects
• Transportation
• Overproduction
• Waiting
• Processing
• Movement
• Inventory
Scrap/Rework
Product Movement
Making more Product than
can be Sold
Operators Waiting
Minimize Number of Steps
Unnecessary Motion/
Money Sleeping
8. Eliminate Waste in Production !
20. Batch-And-Queue
• Producing Goods or Services
in Large Quantities of Work
are Processed Before Moving
to the Next Step
Producer Focus Vs. Customer Focus
21. MUDA
• Wasteful activity and does not add value
Two Types of MUDAs
1) ‘Mura’ – Un-evenness
2) ‘Muri’ – Over-burdening
22. Types of Muda
• Mura (Unevenness): “Products batched together
and pushed through a production plant”
• Muri (Overburdening): “Processes and
operators do not have Sufficient time to carry
out work affects whole process flow”

33. • Produce more than demand or produce it before
needed.
• Visible as storage of material.
• Producing to speculative demand.
• Making more than, earlier than and faster than required
by the next process.
• Causes for overproduction waste include:
• Just-in-case logic
• Misuse of automation
• Long process setup
• Unlevel scheduling
• Unbalanced work load
• Over engineered
Overproduction
34. • Machine to process eliminated
• Principle: Maximize utilization/efficiency of
worker than maximizing utilization of machines.
• Causes of waiting waste include:
• Unbalanced work load
• Unplanned maintenance
• Long process set-up times
• Misuses of automation
• Upstream quality problems
• Unlevel scheduling
Waiting
35. • Minimized by asking why a specific processing step is
needed and product is produced.
• Unnecessary processing steps
• Causes for processing waste include:
• Product changes without process changes
• Just-in-case logic
• True customer requirements undefined
• Over processing to accommodate downtime
• Lack of communications
• Redundant approvals
Processing waste
36. • Does not add any value to product.
• Instead of improving transportation, should be
minimized or eliminated (e.g. forming cells).
• Causes of transportation waste includes:
• Poor plant layout
• Poor understanding of the process flow
for production
• Large batch sizes, long lead times, and
large storage areas
Transportation
37. • Workers, machines, and transport (e.g. due to inappropriate
location of tools and parts) is waste.
• Instead of automating wasted motion, operation itself should
be improved.
• Causes of motion waste include:
• Poor people/machine effectiveness
• Inconsistent work methods
• Unfavorable facility or cell layout
• Poor workplace organization and housekeeping
• Extra "busy" movements while waiting
Motion
38. • Pure waste.
• Prevent defects instead of finding and repairing defects.
• Causes of processing waste include:
• Weak process control
• Poor quality
• Unbalanced inventory level
• Deficient planned maintenance
• Inadequate education/training/work instructions
• Product design
• Customer needs not understood
Making defective products
39. • Not taking advantage of people's abilities
• Causes of people waste include:
• Old guard thinking, politics, the business
culture
• Poor hiring practices
• Low or no investment in training
• Low pay, high turnover strategy
Under-utilizing people:

62. SIX SIGMA
Statistical concept measures a
process in terms of defects (SIX
sigma) level- 3.4 defects per million
opportunities
But, it is much more!
("Delivering Tomorrow's Performance Today“)
64. VGD@IIPM
Philosophy
Reduce variation in business and
make customer-focused, data
driven decisions
Translate customer
needs into operational
measurements
65. Six Sigma
Customer first & uses facts and
data to derive better solution
Target:
•Improving customer satisfaction
•Reducing cycle time
•Reducing defects
68. Objectives of Six Sigma
Critical to quality (CTQ): attributes important to customer
Defect (D): failure to deliver a product/service as required by
customer
Process Capability (PC): process can deliver the quality
Variation (V): perception of the customer, how he/she sees
and feels about the quality of the product
Stable Operations (SO): guarantee a process consistent and
predictable with recued variation
70. 3 Sigma Vs. 6 Sigma
3 Sigma Company 6 Sigma Company
• Spends 15-25% of sales dollars on
cost of failure
• Spends 5% of sales dollars on cost of
failure
• Inspection to find defects • don’t produce defects
• Does not have a disciplined approach
to gather and analyze data
• Use Measure, Analyze, Improve,
Control (MAIC) and Measure, Analyze,

Editor's Notes
Six Sigma is a methodology that provides businesses with the tools to improve the capability of their business processes. This increase in performance and decrease in process variation leads to defect reduction and vast improvement in profits, employee morale and quality of product.
Data is key here. Six Sigma has it’s foundation in Statistics and measurements
Lean has traditionally focused on cycle time reduction, inventory reduction, reduction of floor space, by the elimination of the 7 hidden wastes.
Six Sigma has traditionally focuses on variance reduction (the elimination of “noise factors”) to improve quality.
The goal of both is to produce a financial benefit.
Define process goals in terms of key critical parameters (i.e. critical to quality or critical to production) on the basis of customer requirements or Voice Of Customer (VOC)
Measure the current process performance in context of goals
Analyze the current scenario in terms of causes of variations and defects
Improve the process by systematically reducing variation and eliminating defects
Control future performance of the process
DMAIC is a basic component of the Six Sigma methodology- a way to improve work processes by eliminating defects. The Six Sigma methodology is widely used in many top corporations in the United States and around the world. It is normally defined as a set of practices that improve efficiency and eliminate defects.
Six Sigma has been around for more than 20 years and heavily influenced by TQM (total quality management) and Zero Defect principles. In its methodology, it asserts that in order to achieve high quality manufacturing and business processes, continued efforts must be made to reduce variations.
Initial skepticism was fueled somewhat by our learning from manufacturing. However, the bigger skepticism came from our own history with performance improvement.... Flavor of the Month... Bottom up rather than top down... No commitment from the top...
Recall from Elementary Statistics the standard deviation graph
&gt;Juran said that “all quality improvement occurs on a project-by-project basis and in no other way” . This philosophy is considered an essential element in Six Sigma.
By not using “quality” or “statistics” in the name, it is perceived to be a business system that improves bottom line and only brings in technical details as needed; TQM is perceived to be a technical quality system owned by technical specialists rather than all employees.
&gt;Uses a simple but effective management structure and this in truly a strength. By contrast, TQM required a complex and rigid management structure of many levels.
Why is this so difficult for software and software services?
Remember, SS started in Motorola’s manufacturing divisions where the concept of Statistical Process Control (SPC) was already adopted. We refuse to adopt SPC for software projects because we continue to believe that it doesn’t apply. However, if we are going to continue to use the term “process” then we should also use SPC in order to measure and improve those same processes. Most IT shops haven’t a clue as to how well they are doing now.
