Coping Successfully with External Developments depends on The Organisational Characteristics External Developments Adaptability for survival Organisational Characteristics will determine success or failure TQM helps organisations to adapt continuously to these changes and sustain their performance by reshaping their strategies , improving the culture and improving systems and processes •Vision & Strategy •Structure & Functions •People & Culture •Systems & Processes Slides by : Anjan Ghosh What is Quality ? Some common parameters long life , durability • reliability • fitness for use • zero defects • performance as per specifications • customer satisfaction etc • Genichi Taguchi’s definition of Quality – a revolutionary concept of ”Loss Function” • loss to society – more the loss , less the quality The Japanese Bullet Train is considered to be an example of excellent Quality .
But according to the Taguchi Loss Function it may not be so as there are many losses to society such as farmland depletion , high cost , high energy need etc that may not justify the advantage of time saving…
Slides by : Anjan Ghosh ISO-9000 definition of quality “ degree to which a set of inherent characteristics fulfils requirements” The requirements are of customers . There are millions of customers with their individual needs and requirements . The more the requirements fulfilled the higher is the perception of quality . Is Quality absolute ? It is not absolute . It depends on each person . It depends on country , culture , time etc . What we may have called high quality 20 years back may be low quality now . So it is relative .
But there are some common factors regarding quality that are more or less constant eg . performance , durability , reliability etc ….. Slides by : Anjan Ghosh What is a Product ? Product – ( as per ISO 9000 definition ) Services (eg. Transport, hospital) Software (eg. Computer program, dictionary) Hardware (eg. , chair, spark plug) Processed material (eg. Lubricant, cement) Who is a customer ? Customer Uses the product ( consumers , end-users ) Distributes the product ( wholesellers , dealers ) Influences others about the product
Slides by : Anjan Ghosh Who are our internal customers ? The next person / dept. impacted by our product or service is our internal customer . Eg production dept. is the internal customer of stores dept. The Despatch dept. is the internal customer of production dept. Satisfying internal customers leads to satisfying external customers . Internal customer dissatisfaction means that the Products & processes are having problems and not as per specifications which may be sold to external customers leading to their dissatisfaction Slides by : Anjan Ghosh Dimensions Of Product Quality • Performance – primary operating characteristics • Features – secondary aspects of performance • Reliability – probability of successful performance • Conformance – degree to which operating characteristics meet specified standards • Durability – measure of product life • Serviceability – ease and cost of repair • Aesthetics – look , feel , smell ….. • Perceived Quality – reputation , image Slides by : Anjan Ghosh 10 Dimensions of Service Quality • Reliability – consistency of performance ( dependability ) • Responsiveness – willingness, timeliness, readiness…. Competence – skills & knowledge for performing service • Access – approachability & ease of contact • Courtesy – politeness , friendliness ….. • Communication – information , relationship management • Credibility – trustworthiness , honesty , belief ….. • Security – freedom from risk , confidentiality . • Understanding customer needs – specific requirements • Tangibles – physical evidence of service , facilities, tools ,appearence Slides by : Anjan Ghosh What is TQM ?

Slides by : Anjan Ghosh Process Control Left to itself a process will drift from its set-point due to the chance and assignable causes . If the drift is too much the process may go outside the tolerance limits or target values . So there is a need for controlling the process by means of continuous feedback and corrections – either manual or automatic . The ability of a process to stay within the tolerance limits ( and hence In control ) is called its stability The ability of a process to go near to the target value is called Its capability Slides by : Anjan Ghosh Requirements of control knowledge of what is to be done – procedures , instructions , standards • knowledge of what is being done – feedback , monitoring & measurement • means of adjusting process – correction and corrective action Slides by : Anjan Ghosh Standard Organisations International Organisation for Standardisation – ISO (Gives all standards except electronics and electricals) International Electro-technical Commission – IEC (Gives all standards relating to electricals and electronics ) American Society for Testing & Materials – ASTM Deutsches Institut fur Normung – DIN Japanese Industrial Standards – JIS

Instead of ad-hoc fire-fighting approaches , a structured methodology would have much more probability of success . Slides by : Anjan Ghosh 6 Sigma : A Methodology to reduce rejection & variation • Variation is natural and random . But when variation becomes too large and assignable causes creep in – defects occur . So defects must be reduced by eliminating the assignable causes and limiting the effects of the natural ( random ) causes . • Over the past decades quality engineers have been trying different tools and techniques to reduce variation . All these tools and techniques , fortified by more powerful ones , have been collected in a basket and given the name “ 6 Sigma “ . It was invented by Motorola in the 1980? s . • 3 Sigma process has 66807 PPM reject level in the long run ( Cpk = 1 ) 6 Sigma process has 3. 4 PPM reject level in the long run ( Cpk = 2 ) Slides by : Anjan Ghosh The Six Sigma Project Methodology – DMAIC Cycle Six Sigma Improvements are done through 5 – Stage Projects. Define Measure Analyse Improve Control- Determine what needs to improve , select parameters , set targets, set up teams , plan actions – Current state against desired state.
Gather data . – From data find root causes of the gaps by using various statistical techniques . – Select and implement best solutions by using various tools / techniques – Long-term sustainability and monitoring mechanisms. Slides by : Anjan Ghosh Poka-Yoke – Mistake Proofing Prevention is better than cure The earlier the better 85 % of failures arise due to wrong / insufficient design of product or manufacturing process . So to improve quality and prevent failures / errors it has to be taken care in design and not depend on person „s skills or judgement.
Anybody can and should practice poka yoke in the workplace. Poke yoke does not necessarily require any complicated science or engineering sometimes it just needs common sense and the appropriate poka yoke device – and the will to do zero defects . Poka yoke devices should have the following characteristics: 1) 2) 3) 4) 5) useable by all ; simple to install; does not require continuous attention from person (ideally, it should work even if the person is not aware of it); low-cost; provides instantaneous feedback, prevention, or correction. Slides by : Anjan Ghosh Examples of Poka Yoke ) A jig that prevents a part from being misoriented during assembly 2) Non-symmetrical screw hole locations that would prevent a plate from being screwed down incorrectly 3) Electrical plugs that can only be inserted into the correct outlets 4) Notches and assymetric pin configuration in computer connectors 5) A flip-type cover over a button that will prevent the button from being accidentally pressed 6) Sounds alarm and does not start car if doors are not locked properly 7) A punching tool works only when operator presses two different switches with two hands and holds them down 8) A wrapping machine won’t work if serial number is missing

Housekeeping & Workplace Organization • Housekeeping While many people may consider housekeeping an unappealing topic, we should realize that housekeeping is closely tied to many important aspects of running a world-class organisation. For example, there is a strong linkage between the level of housekeeping and the level of scrap, machine breakdowns, accidents, absenteeism, inventory and improvement suggestions. If we understand this linkage well, rather than taking a look at each issue independently, each of us should better understand what actions are required to increase improvement activities.
Housekeeping is everybody’s job. Slides by : Anjan Ghosh Housekeeping & Workplace Organization • Workplace Organization Housekeeping is tied closely to better workplace organization. The value of clean floors and machines is not simply a pleasing appearance. Clean surfaces expose problems such as oil leaks and cracks so that corrective action can be taken as early as possible. Similarly, in organizing dies or tools, it does not make much sense to nicely orient the dies or tools in the rack if the most frequently used dies are far away from the machine.
Housekeeping and workplace organization have a definite economic impact. Slides by : Anjan Ghosh 5-S & Housekeeping Some Examples of Bad Housekeeping • Materials lying on floor. • Windows & emergency exits blocked . • Unmarked shelves/ racks. • Unclean toilets. • Wrong tool in tool box. • Dangling wires. • Obsolete documents in current files. • Oil dripping from leaks. • Material without identification. • Notice board not updated. • Water stagnating in drains. • Clock slow/ fast. • Rejected material in ok area. • No marked areas for office furniture. Slides by : Anjan Ghosh Consequences of poor Housekeeping Large amount of defective products • Waste of untraceable (lost) material • Large number of m/c breakdowns • Inefficient routing of material flow • High inventory levels • Low morale & motivation • High level of absenteeism • Low number of improvement suggestions • High obsolescence • Lost time in looking for tools • Concealed problem area? s • Unaccounted work in progress and spare parts • Safety & health problems • Shabby & dirty looks • Low confidence of customers & visitors • Slides by : Anjan Ghosh THE FIVE PILLARS OF HOUSEKEEPING ( 5-S ) BUSINESS EXCELLENCE SEIRI SEITON SEISO SEIKETSU SHITSUKE
PRINCIPLES OF BETTER WORKPLACE ORGANISATION Slides by : Anjan Ghosh The 5 Pillars of Housekeeping Seiri (Structurise) – Take out unnecessary items and dispose them away. Keep only essentials. Seiton (Systematise) – Arrange necessary items in a proper order so that they can be easily located and picked up for use. Seiso (Sanitise ) – Clean the workplace thoroughly using proper tools & equipment. Seiketsu (Standardise) – Maintain a high standard of housekeeping at all times. Check & audit periodically. Shitsuke (Self-Discipline) – Train and motivate people to follow good housekeeping practices & discipline.
Slides by : Anjan Ghosh Housekeeping What can I gain from 5-S ? • • • • • • • 5-S makes one’s workplace more pleasant 5-S helps in work efficiency 5-S and safety go hand-in-hand 5-S leads to better quality & higher productivity 5-S leads to waste reduction & hence lower costs 5-S leads to lower inventories & on-time deliveries 5-S leads to lower machine downtimes Slides by : Anjan Ghosh Lean Manufacturing Lean is about doing more with less: such as less time, inventory, space, labor, and money. “Lean manufacturing”, aims at eliminating waste, simplifying procedures and speeding up production.
Also known as Toyota Production System (TPS) as its principles were first proposed and put to use in Toyota by Taiichi Ohno during the 1970? s . This system, more than any other aspect of the company, is responsible for having made Toyota the respected company it is today. Toyota has long been recognized as a leader in the automotive manufacturing and production industry. [ By eliminating waste you can do more with less: Less capital equipment Less floor space Less operator effort Less direct labor Less indirect labor Less inventory Less lead time Slides by : Anjan Ghosh
Lean identifies seven types of waste ( Muda in Japanese ) : 1. Over-Production – A product that cannot be sold or has to be dumped at a reduced price is wasteful. Also producing product before the customer needs it requires the part to be stored and ties up money in inventory. 2. Inventory – Excess Inventory ties up a great deal of cash, which is wasteful. Stockpiling inventory between processes is wasteful. 3. Transportation – Unnecessarily moving a part during the production process is wasteful. It can also cause damage to the part, which creates wasteful rework. 4.
Correction – Re-work/ repair of defects is a large source of waste. Additionally, sorting and inspecting parts is wasteful .. 5. Motion – Unnecessary or awkward operator motions put undue stress on the body and cause waste. 6. Processing – Unclear customer requirements cause the manufacturer to add unnecessary processes, which add cost to the product. 7. Waiting time– People and machines remaining idle between operations is wasteful. Slides by : Anjan Ghosh Total Productive Maintenance ( TPM ) Breakdown of machines & equipment has to be avoided as it decreases productivity , Increases cost and may affect quality .
Therefore maintenance is vital . Breakdown Maintenance (BM) means rectifying after the breakdown has happened . In order to keep machines healthy and fit for production Preventive Maintenance (PM) also known as Time Based Maintenance (TBM) has to be done as per a planned schedule . In some cases even Preventive Maintenance is not enough. We need to predict failures by measuring the parameters of the machine like vibration , temperature , corrosion etc . If the state of the health after the measurement is not found to be OK then maintenance or change of parts is done . This is called Condition Based
Maintenance ( CBM) Small everyday maintenance can be done by the operator of the machine like lubricating , cleaning , tightening , inspecting etc . The change of parts or CBM or TBM or BM can be done by specialist maintenance people. By doing proper maintenance the productivity and life of machines can be increased with Improvement in quality and decrease in cost . A lot of training and involvement of people are reqd. to ensure that proper maintenance is done . Proper records of the maintenance and history cards of the machines has to be kept . For each breakdown and failure analysis needs to be done to find the root cause of the failure .
These learnings will help in designing of better machines . This whole methodology is called as TPM because it involves many people & depts. Slides by : Anjan Ghosh Benchmarking – A Process of Improvement to Reach the Best • Comparison with past results / targets in the same function/ department. • Comparison with other functions/ depts within the organisation at same location. • Inter location (sister plants/offices) of same organisation. • Comparison with other organisations in same industry – local, global. • Comparison with other industries – local, global.
Benchmarking is not only of results but on the processes. Often benchmarking would require intensive studies and redesigning of products and processes. Benchmarking is not spying or blindly coping others . Understanding & learning reqd. In many cases there is collaboration between organisations for mutual benefit . Benchmarking is a dynamic exercise and not one-time , because by the time the Improvements are done the best being benchmarked would have improved further. Slides by : Anjan Ghosh Economics Of Quality Quality Cost Cost of control Cost of lack of control (cost of poor Quality) Prevention Cost Appraisal cost
Internal Failure Cost • Costs associated with defective products & components that fail to meet quality requirements and cause manufacturing losses. • Cost associated with designing , implementing, maintaining and improving the products, services and quality system. It includes auditing the quality system • Costs associated with measuring, evaluating or inspecting products or components to assure conformance with quality standards and performance requirements External Failure Cost •Costs generated by defective products being sent to customer s Slides by : Anjan Ghosh Economics Of Quality WHERE IS THE POINT OF OPTIMUM QUALITY COST ?

The name reflects the balance provided between short-and long-term objectives between financial and non-financial measures, between lagging and leading indicators, and between external and internal performance perspectives. Slides by : Anjan Ghosh Involvement of People The full potential of people needs to be harnessed and people motivated to contribute towards improvements in a voluntary way . The aim would be to make jobs , enjoyable and satisfying . Management needs to provide training and development and provide support for ongoing improvements both for individuals and teams .
Also give due rewards & recognition to keep motivation high . In most cases the rewards are non-monetary . Suggestion Box : Employees can give suggestions ( dropped in a box ) . Which are evaluated by a committee and if found suitable are implemented . Kaizens : Small improvements in machines , processes , materials etc by individuals or teams Teams go by different names : Quality Circles ( QC? s) – where 5-8 non-mgt employees work under guidance of a facilitator (mgt ) and take up improvement projects in their dept or area of work . QC? solve one Problem after another with same members and may be working as a team for several years Small Group Activities (SGA? s) : Work like QC? s but members can be from other depts also . After problem is solved SGA is disbanded .
