CustomerPerspective
Barriers to accomplish the Vision
Constraints or bottlenecks in the business processes are the barriers to higher profit and higher customer satisfaction
The effects of the constraints appear in the form of waste of materials, machines, energy, time, efforts etc.
How to improve Business performance?
Continual Improvement in business processes through:
Detection of waste Elimination of waste
Objectives of Waste Assessment?
To identify the quantum of current Waste in the entire value stream of the company
To assess the cost of Waste
To determine the reduction potential of Waste
Use the above information to Prioritize the improvement action needed to
eliminate the waste Develop Improvement Action Plan
Business Process
A Business process transforms inputs into out puts. Any transformation process or business activity either;
creates Value or
generates Waste (Muda)
Value
Waste
What is Value?
Value : A capability provided to a customer at the right time at an appropriate price, as defined in each case by the customer.
Value is created by the producer. From customer’s point of view, this is why producer exists.
What is Waste (Muda)?
Waste is defined as any human activity which absorbs resources but creates no value;
Mistakes which require rectification Production of items no one wants so that inventories pile up Processing steps which are actually not needed Movement of employees and transport of goods from one place to
another without any purpose Group of people in downstream activity waiting because an
upstream activity has not delivered in time Goods and services which does not meet the needs of customer
Types of Waste
Waste of Over production Waste of Unnecessary
Inventory Waste of Defects Waste of Unnecessary
Motions Waste of Inappropriate
Processing Waste of Waiting Waste of Transporting
Waste of Untapped Human Potential
Waste of Inappropriate Systems Waste of Energy & Water Waste of Material Service & Office Waste Waste of Customer time Waste of Defecting Customers
1. Waste of Overproduction
Produced to compensate loss in production due to absenteeism, equipment break down, higher rejection rate, inconsistency in operation
Instead of eliminating the root cause companies go for overproduction
2. Waste of Inventory
More than the required stock of finished product, work-in process and raw materials do not add any value
They add cost of operation by blocking more money, increased requirement of transportation, storage and handling
In many situations extra inventory gets scrapped due to limited shelf life or becomes obsolete due to design changes
3. Waste of Defects
Defects or rejects interrupt production and require expensive rework
Rejects have to be scrapped Defective products may
damage the tools and jigs installed on machines
4. Waste of Motion
Any motion of a persons body not directly related to adding value is non productive
Any action such as lifting or carrying a heavy object, should be avoided
5. Waste of Processing
Sometimes inadequate technology or design leads to muda in processing
Unproductive striking of the the press, de-burring of the product, machine idling cause muda
6. Waste of Waiting
Muda of waiting occurs when the hands of the operator are idle
Operator’s work is put on hold because of line imbalances, lack of parts, or machine downtime or operator monitoring the machine when machine is adding value to the job
7. Waste of Transport
Transport is an essential part of operations, but moving materials and products add no value
Any process physically distant from main line adds muda of transport
Use of conveyors, fork lifts, trucks and other transport system has to be minimized
8.Waste of Untapped Human Potential
The purpose of efficient system is “to create thinking people”
Human potential just does not need to set free. It requires clear communication as to what is needed (both from management and to management), it requires commitment and support, it requires a culture of trust and mutual respect.
Example : Not using creative brain power of employees, not listening, thinking that only managers have idea worth pursuing
9. Waste of Inappropriate system
Unnecessary record keeping, checking, reconciling is pure waste
It is not the operation that consumes time and money; it is the paperwork or systems
Remove waste before automation
10. Waste of Energy & Water
Energy here refers to sources of power: electricity, gas, oil, coal and so on
Energy & water are not only the significant sources of cost , but there is moral and social responsibility to preserve them for future generations
11. Waste of Materials
Conservation of materials is direct saving of cost.
To reduce the wastage of materials a Life Cycle Cost approach is needed.
Material conservation has to be incorporated during design, manufacturing, consumer usage and beyond consumer use in recovery and manufacturing
12. Service & Office Waste
All manufacturers are linked with service operations. Over production, for instance can relate to excess photocopying, wasted food and excess meetings. Inappropriate processing may relate to excess e-mails, copies in triplicate, many presentations
13. Waste of Customer Time
Where a customer is forced to wait in a queue or to wait for value adding services. This is primarily a scheduling issue. More of this waste occurs where a customer has to provide the same information several times
Waiting causes customer inconvenience or customer dissatisfaction
14. Waste of Defecting Customers
A waste that is causing concern to service managers and marketing professionals is the loss of existing customers
“It costs five times more to acquire a new customer as it does to retain the existing one”
Economic Value of Waste
Since every business activity absorbs resources and every resource has a cost
Every waste has a cost, and that is direct loss to the company
Crisis & Renewal(Harvard Business School Press)
David Hurst, author of the famous book Crisis & Renewal makes a strong case that firms need to “burn the forest” in parts of their organization in order to keep the whole organization from going up in smoke at later point
Creative solutions (identification & elimination of waste) to specific operations in crisis may be the best way to create “fire breaks” and eventually renew the whole forest.
Identify Waste in a phased manner
Waste of Over production Waste of Unnecessary
Inventory Waste of Defects Waste of Unnecessary
Motions Waste of Inappropriate
Processing Waste of Waiting Waste of Transporting
Waste of Untapped Human Potential
Waste of Inappropriate Systems Waste of Energy & Water Waste of Material Service & Office Waste Waste of Customer time Waste of Defecting Customers
Where the waste is generated?
Waste is generated in
the Value Stream
What is Value Stream?
Value stream is the set of all the specific actions required to bring a specific product through the three critical management tasks of any business:
Problem Solving task Information Management task Physical Transformation task
1.Problem Solving Task
Running from concept through detailed design and engineering to production launch
Design flow across the value stream
2. Information Management Task
Running from order taking through detailed scheduling to delivery
Information flow across the value stream
3. Physical Transformation Task
Proceeding from raw materials to a finished product in the hands of customer
Production flow across the value stream
Core Business Processes of Value Stream
Materials Management Pickling Cold Rolling Annealing & Temper Rolling Galvanizing Color Coating Packaging & Delivery
Value Stream Analysis Search for Waste
1. Map every step of the process “door-to-door” level 2. Identify every activity of the process at input, process and output
stages (Value added and Non-value added)3. Detect waste generated in each activity of the process (of all items) at
input, transformation, and output stages4. Quantify the effect of each non-value added activity or waste in
measurable units (per MT of output, %, etc.)
5. Classify the waste in three categories Those which create No value but are Unavoidable due to their
natural characteristics or beyond control of management Those which create no value but Currently inevitable due to
situational/ technological limitations (Type:1 Waste/Muda)
Value Stream Analysis Search for Waste
Those actions do not create any value and Can be Eliminated by improving the operating practices or processes (Type -2 Waste/Muda)
6. Evaluate the Cost of each waste (per MT of out put)
7. Assess the reduction potential of waste based on company standard/international bench marks (Consult Specialists)
9. Compile the quantity and cost of all types of wastes and their reduction potential (quantity & cost on annual basis)
10. Rank the the waste in their descending value order for prioritizing the waste elimination plan.

Classification of Waste?
Unavoidable waste: Which are not adding any value, but can not be avoided due to natural characteristics or beyond management control. Example: a definite % of Fe loss in slag, security, side trimming of HR coils etc.
Type-1 Waste: Not adding any value but are unavoidable in the current situation. These can be eliminated by making radical change, improvement in technology,innovation in system etc.
Type-2 Waste: Not adding any value and can be easily avoidable. These wastes can be eliminated by making improvements in processes and operational practices using techniques like Kaizen, Six Sigma, CRM, TPM, SCM etc.
