Workforce commitment
Managers must support LEAN manufacturing by providing subordinates with the skills. tools, time, and other necessary resources to identify problems and implement solutions.
Engineering to Order (ETO) Manufacturing Strategy
Manufacturing process in which the component is designed, engineered and built to specifications only after the order has been received. Building a unique product every time cost of poor quality very high -Longest Lead Time from customer's perspective
Make to Order (MTO) Manufacturing Strategy
Manufacturing strategy that typically allows customers to purchase products that are customized to their specifications. Manufacture send product once the customer places the order No excessive inventory Appropriate for highly configured products such as computer servers, aircrafts, automobiles that are expensive to keep in inventory. - Pure Pull Strategy/ System
Non Value added process

Make to Stock (MTS) Manufacturing Strategy
-To manufacture products based on demand forecasts. -Pure Push Strategy/System -Accuracy of the forecast is critical -Used for most daily necessities such as processed foods, and textiles. Shortest Lead Time from customer's perspective -Issue: Avoid having excess inventory. Make the correct product, at the correct time, in the correct quantity.
3 main foundation aspects of Six Sigma
1- Quality is defined by the customer 2- Use of technical tools such as statistical quality controls and the 7 tools of quality 3- People involvement: all employees involved in six sigma program, all employees identify quality problems, and well defined and specific six sigma roles.
The 7 elements of LEAN manufacturing
1- Waste reduction 2- LEAN layouts 3- Inventory, set up time, and changeover time reduction 4- Small batch scheduling and uniform plant loading 5- LEAN supply chain relationships 6- Workforce empowerment 7- Continuous improvement
LEAN history
1910's Henry Fords mass production line - continuous assembly - flow systems 1940's Taichii Ohno & Shigeo Shingo create Toyota Production System (TPS)
Six Sigma
A quality management process: - Seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.
Efficient Consumer Response LEAN concept
A strategy to increase the level of service to customers through close cooperation among retailers, wholesalers, and manufacturers.
Statistical tools: control charts
Allows firm to; - Visually monitor process performance - Campare performance to desire levels/standards - Take corrective actions
Uniform Plant Loading
Also called front loading Planning up to capacity in earlier time periods to meet demand in later time periods
Six Sigma philosophy
An enterprise and supply chain wide-philosophy that emphasizes a commitment towards excellence, encompassing suppliers, employees, and customers. Identification and reduction of defects/ errors. Focuses on reducing defects and variations.
Just in Time LEAN concept
An inventory strategy to decrease waste by receiving materials only when and as needed in the production process, thereby reducing inventory costs.
Cost of good quality
Appraisal costs Prevention costs
Cost of quality
Approach that support a company's efforts to determine the level of resources necessary to prevent poor quality, and to evaluate the quality of the company's products and services.
Joseph Juran
Defined quality as "fitness for use" He developed the concept of the cost of quality. - Quality planning - Quality control - Quality improvement
Kaoru Ishikawa
Developed one of the first tools in the quality management process, the cause and effect diagram, which is also called the ------- or fish bone diagram.
LEAN elements: Waste (Muda) Reduction
Firms reduce cost and add value by eliminating waste. Waste encompasses; - wait times - inventory - material and people involvement - processing steps - variability - any other non value added activities
Statistical Tools- Pareto Analysis
For presenting data in an organized fashion, indicating process problems from most to least sever.
Cost of poor quality
Internal failure costs: product doesn't meet quality standards and is detected before delivered to customer external failure costs: product doesn't meet quality standards and is detected after delivered to customer
Keiretsu Relationships LEAN concept
Involves companies both upstream and downstream of a manufacturing process, remaining independent but working closely together for mutual benefit.
LEAN is culture
LEAN is NOT a tool box of methods, ideas, and methodologies. LEAN provides value for customers through the use of the most efficient resources possible.
LEAN manufacturing & SCHM
LEAN manufacturing is a natural fit within the discipline of supply chain management as all of the LEAN goals and objectives help to facilitate an efficient and effective supply chain.
Malcome Baldrige National Quality Award
Objectives; - Stimulate firms to improve - Recognize firms for quality achievements - Establish guidelines Categories Measured: - Leadership - Strategic planning - Customer and market focus - Information and analysis - Human resource focus Process management - Business results
Carbon neutral
Offsetting the carbon footprint of a firm's operations
LEAN philosophy
Operating philosophy of waste reduction and value enhancement and was originally created as the Toyota Production System (TPS). Focuses on eliminating wastes and improving efficiencies
The five S's
Originally Japanese words related to industrial housekeeping - Sort - Straighten - Shine - Standardize - Sustain
LEAN elements Inventory, Set up Time, and Changeover Time Reduction
Some inventory might be necessary but excess inventory is a waste Reducing inventory can free up capital and reduce holding costs Pull approach
Acceptance Sampling Risks
Supplier's risks: the buyer rejects a shipment of good quality units because the sample quality level did not meet the acceptance standard (type I error) Buyer's risk: the buyer accepts a shipment of poor quality units because the sample falsely provides a positive result against the acceptance standard (type II error)
Small batch scheduling
The ideal schedule is to produce product as quickly as possible and at the same rate as customer demand. Large batches can exasperate the bullwhip effect as production in large batches creates an uneven workload. Lean manufacturing attempts to reverse this through:
Value
The inherent worth of a product as judged by the customer, and reflected in its selling price and market demand. Anything for which the customer is willing to pay.
Manufacturing Management
The management of all the processes, which are involve din manufacturing. It includes the management of personnel, management pf raw materials, planning for production.
Quick Response LEAN concept
The rapid replenishment of customer stock by a supplier with direct access to data from the customer's point of sale.
Motorola
company that originated the concept of Six Sigma
LEAN & Six Sigma
philosophies mindsets they complement one another LEAN + Six Sigma= Faster Speed & Better Accurracy
Line flow manufacturing process
process that has standard products with a limited number of variations moving on an assembly line through stages of production. Ex. Ford
Continuous flow manufacturing process
process that is used to manufacture such items as gasoline, laundry detergent, and chemicals. Inflexible process High capital Investment
batch manufacturing process
process that manufactures a small quantity of an item in a single production run.
LEAN supply chain relationships
suppliers and customers work to remove waste, reduce cost, and improve quality and customer service. Mutual dependency and benefits occur between these partners.
Voice of the Customer (VOC)
term used in business to describe the in depth process of capturing internal and external customer's stated and unstated expectations, preferences, likes, and dislikes.
Total cost of manufacturing (TCM)
the complete cost of producing and delivering product to your customers. incorporates both fixed and variable costs. Generally expressed as a cost per unit
LEAN elements Set up Time, and Changeover Time Reduction
the time taken to prepare and format the manufacturing equipment and systems for production. The time taken to adapt and modify manufacturing equipment and systems to produce a different product or anew batch of the same product. Both considered a waste because they are non value added operations.
