- -The International Organization for Standards (ISO) was formed after World War II
-The ISO 9000—International Quality Standard (first published in 1987) is a family of various aspects of quality management and contains some of ISO's best known standards.
-The standards provide guidance and tools for companies and organizations who want to ensure that their products and services consistently meet customer's requirements, and that quality is consistently improved.
- -Six sigma approach is to identify sources of variability and then systematically reduce them. Get to the "root cause"
-The six sigma goal is to achieve a process standard deviation that is six times smaller than the range of outputs allowed by the product's design specification
-DMAIC methodology is a systematic approach to eliminating defects and keeping the process in control
- Modular or adjustable product building blocks
Predictable components/functions interactions
Standardized process/skill building blocks
Reasonable lead times, steps, work content
- -TCM generally expressed as cost per unit
-Procurement and production costs go down as volume goes up (generally-step function applies as more capital is required to produce)
-Inventory and warehousing costs go up as volume goes up
-Transportation costs go down as volume goes up, but level off at high volumes
- - sets out the requirements of a quality management system.
This standard is being replaced with ISO 9001:2015 The final updated version is expected by the end of 2015.
- Sufficiently large customer segment that values "translatable variety"
Turbulent, dynamic market
Unpredictable demand - but not entirely unpredictable!
Little impact of regulation or other constraints (designer drugs?
- Product variety: High
Valume: very low
Lead time: Very long
Do any JOB that is needed
- features economies of scale, large volumes, long production runs, low variety, and distribution channels
Note: The textbook refers to this as Make to Plan (MTP)

the measure of elapsed time between release of a work order to the shop
floor and completion of all work on the product to achieve
- Three sigma quality level
Produces defect free product 99.74 percent of the time
66,807 defects per million parts produced
Six sigma quality level
Produces defect free product 99.99966 percent of the time
3.4 defects per million parts produced
- Likelihood that the product will perform throughout its expected life
- Just-in-Time (JIT)
Materials Requirements Planning (MRP)
Design for Manufacture (DFM)
Design for Logistics (DFL)
- sets out guidance on internal and external audits of quality management systems.
for logistics concept incorporates the requirements and framework for
logistical support of the product in the early phases of product
What we are going to make
How we are going to make it
What logistics capabilities do we need
How we are going to integrate our suppliers into the process
Any subassembly manufacture by suppliers
The need for outsourcing of some parts or assemblies
- Waste Reduction
Lean Supply Chain Relationships
Inventory & Setup Time Reduction
Small Batch Scheduling
Lean, in particular Value Stream mapping, is a great tool in administrative processes
- Procurement has a key role in insuring all the components are obtained on time to make an end item
Key information requirement is the bill of materials (BOM)
Particularly for more complex manufacturing (i.e., MTO, ETO) where large numbers of components or subassemblies are used to produce a final product
-Planning sometimes spans multiple manufacturing locations
- -Design-for-assembly - focuses on minimizing the number of parts and on easing assembly processes.
-Design-for-product-serviceability - focuses on easing the disassembly and reuse of product components.
-Design-for-six-sigma - systematically evaluates the consistency with which a good or service can be produced or delivered given the capabilities of the processes used.
- focuses on how to make a quality management system more efficient and effective
- What different functions or tasks can the product perform
- -Lean is a philosophy that is focused on the customer
-Defining principle is the elimination of "waste". Waste is anything that does not add value for the customer
-Lean emphasizes the minimization of the amount of all resources (including time) used in the operation of a company
- 1.)Produce only the products that customers want
2.)Produce products only as quickly as customers want them
3.)Produce products with perfect quality
4.)Produce in the minimum possible lead times
5.)Produce products with features that customers want and no others
6.)Produce with no waste of labor, materials or equipment; designate a purpose for every movement to leave zero idle inventory.
7.)Produce with methods that reinforce the occupational development of workers
- The actual life expectancy of the product
- -They have to conform to an externally defined set of standards for quality and delivery of service
-They are usually more open to sharing supply chain information
-They welcome building relationships with their customers
-Formal processes in place for continual
- easier for procurement to initially qualify and
-Certification is done by an external register agency
-Recertified every three years
- is when base components are made, stocked to forecast, but products are not assembled until customer order is received
Manufacturing postponement practiced here
- -Constraints interact with volume and variety to create realistic manufacturing plans
-Capacity is how much can you produce in a given unit of time
-Equipment considers how flexible it is
-Is one particular piece a bottleneck?
-Setup/Changeover considers how quickly can you
change from one variety of product to another
- Procurement and production activities
Inventory and warehousing activities
- involves frequent product runs and high repetition of small lot sizes
-Processes that can rapidly switch production from one product to another while retaining efficiency are said to have economy of scope
