Performing a task right the first time means: | every step in the process of performing a task is successfully completed the first time around without failures or quality problems |
Three main stages in quality management and process control | (1) no quality management, (2) inspection, and (3) process control |
Myth: Quality work takes more time | Reality: Quality work requires a good and structured process, and then it takes less time |
Myth: Quality costs more money | Reality: High-quality work and a quality process cost less money because they result in less rework and fewer cycles, and they reduce the garbage plant |
Myth: It is not possible to provide a quality service or quality product in large quantities | Reality: It is possible to provide quality service and produce a quality product even in large quantities if the process is good, consistent, and reliable…and a quality process of selecting, training, and controlling the employees. |
Six Sigma (1982 Motorola) | -represents a well-thought-out packaging of quality tools and philosophies in an honest effort to provide rigor and repeatability to quality improvement efforts -cost-reduction-oriented than traditional continuous improvement.This made it popular w/ CEOs |
Organization of Six Sigma | champions, black belts, green belts, and in some situations, yellow belts |

Reasons for Six Sigma Failure | Lack of Leadership by Champions, Misunderstood Roles and Responsibilities, Lack of Appropriate Culture for Improvement, Resistance to Change, Faulty Strategies for Deployment, Lack of Data |
Statistical Thinking | All work occurs in a system of interconnected processes All process have variation (The amount of variation tends to be underestimated) Understanding variation and reducing variation are important keys to success |
Type I error | Producer's Risk |
Type II error | Consumer's Risk |
NonRandom Variation | “Special Causes” Results from some uncommon event Dispersion and mean of the process are changing Process that is not repeatable Find a bad symptom, then “ask why 5 times” to get to the underlying core problem. jhb |
Variable | a continuous measurement such as weight, height, or volume. |
Attribute | is either counted or is a yes/no decision |
Developing Process Charts | Identify critical operations in the process, Identify critical product characteristics, Determine whether the critical product characteristic is a variable or an attribute. Select the appropriate statistical process control chart, Establish the control l |
Just-In-Time | From raw material to final customer, deliver each item just as needed. Drive continuous improvement by striving for faster flow of goods, which causes problems and forces one to deal with them. |
Origin of Just-In-Time | The idea for JIT came to Toyota VP Taichi Ohno while visiting a U.S. supermarket. Shigeo Shingo made JIT possible at Toyota by dramatically lowering setup times. Shingo is known today for SMED (Single Minute Exchange of Dies). |
Just-In-Time in the USA | brought to the states by the American Production and Inventory Control Society (APICS) with their Zero Inventory Crusade and by the big three automobile manufacturers, who adopted JIT and required their suppliers to adopt it. |
Management Commitment | means that managers are educated in the nature of the system they want implemented, actively involved in bringing about the implementation, and interested and concerned about the impact the system will have on workers. |
Cards | standardized containers, or even a square painted on the floor may be used to signal to a worker that it is time for him or her to produce one container of parts |
Setup Time | the time between finishing the last part of one order and starting the first part of the next.. reduction is crucial to smooth flow of materials |
Long Setup Times | Long setup times disrupt the smooth flow of parts through a facility and cause workers at other work centers to wait for an authorization to work (the Kanban signal) |
Obsolete Measures of Performance | Equipment utilization, Worker efficiency, Individual incentives, Costing based on direct labor hours |
3 Rules of JIT | Rule I: Work only as needed in terms of time, quantity, and specifications. Rule II: Work in small, appropriate, and smart batches. Rule III: Avoid waste and activities that do not add value to the organization. |
Transfer Batch | The number of units, number of work hours, or frequency of transfer between one work station and another. |
Process (working or production) Batch | The number of units (or labor hours) that are worked on continuously at a workstation. This is the amount of work between one setup and the next |
Examples of Waste | Overproduction Waiting times Unnecessary conveyance Rejected products in processing Surplus stock |
Purpose of Phase Review | is to establish agreement that all required work for that Phase has been done properly, and that the organization supports a decision for the project to proceed to the next phase, or conversely, to terminate the project |
Why projects Fail... | *Uninvolved Users/Customers *Poorly Defined End Products *Scope and the Multiplication of Interfaces *Uncontrolled Changes *Undisciplined Management System *Inappropriate Focus on Technology *Assuming 100% Availablity of Committed Resources *Poor S |
Why forecast? | Materials Staffing Equipment Physical plant |
How long should the Forecast be? | As long as the longest lead time for the thing to be planned. For example, power companies must plan 15 years ahead to build a new plant |
Independent Demand Items | finished goods (such as automobiles) and replacement parts (such as replacement tires) need to be forecast. |
Dependent Demand Items | component parts (such as tires included as original equipment) are derived from demand for their parent items. |
Forecasting Techniques | Moving averages Weighted Moving Averages Exponential Smoothing Decomposition |
Forecast Accuracy | measures how far, on the average a forecast is removed from actual demand |
Forecast Bias | measures the tendency of the forecast to be systematically either too high or too low |
Supply Chain Defenition | consists of all stages involved, directly or indirectly, in fulfilling a customer request. The supply chain not only includes the manufacturer and suppliers, but also transporters, warehouses, retailers, and customers themselves. |
The value a Supply Chain generates: | is the difference between what the final product is worth to the customer and the effort the supply chain expends in filling the customer’s request. For most commercial supply chains, value will be strongly correlated with supply chain profitability. |
Strategic decisions made by companies include: | the location and capacities of production and warehousing facilities, products to be manufactured or stored at various locations, modes of transportation to be made available along different shipping legs, and type of information system to be utilized |
Supply Chain Planning | the supply chain’s configuration determined in the strategic phase is fixed. Companies start the planning phase with a forecast for the coming year of demand in different markets. Planning includes decisions regarding which markets will be supplied from |
How is Strategic Fit achieved? | Understanding the customer. Understanding customer needs helps the company define the desired cost and service requirements. Understanding the supply chain. There are many types of supply chains. A company must understand what the supply chain is desig |
After product becomes Commodity: | Demand has become more certain Margins are lower due to an increase in competitors and more competitive pressure Price becomes a significant factor in customer choice |
Obstacles to proper balance between responsiveness and efficiency: | Increasing variety of products Decreasing product life cycle lengths Increasingly demanding customers Fragmentation of supply chain ownership Globalization Difficulty executing new strategies |
Paradigms | the way we see the world - not in terms of our visual sense of sight, but in terms of perceiving, understanding, interpreting. - Stephen Covey -Paradigm shifts causes you to see the world differently. |
