lean manufacturing is a methodology that focuses on manufacturing systems while simultaneously maximizing productivity
Making processes better leads to reduced
Rework
Scrap
Warranty costs
Inspection costs
everything we do that costs something without adding value to the product
waste
Value added = Maximum
Non-value added = Minimum
producing in excess of customer demand or earlier than required
overproduction
product, people, or machines pending action
delays
processing in excess of customer requirements
excessprocessing
people or product moving between processes
transportation
materials and product in excess of immediate customer requirements
inventory
people and machines movement while performing tasks
motion
repeating task due to poor quality
defects
is the continuouselimination of waste
continuous improvement
Elimination of waste
Identify waste
Search for causes
Implement continuous improvement
Check and Measure results
Japanese term or technique used in manufacturing and process management to prevent errors or defects from occurring during production or operations.
Poka-Yoke
ZDQ stands for?
ZeroDefectQuality system
No fingerpointing! Operators and Machines will sometimes make mistakes
almost any business activity can be considered a process
productionprocesses involve the flow of material, machining, assembly, and packaging
To reduce quality defects, we must
Understand the process of its relationship to other business processes
Identify the inputs and outputs of the process
Know who are the suppliers and customers of the process
a component of ZDQ which is one of the basic approaches to inspection
point of origin inspection
Point of Origin Inspection
Check optimum process conditions before processing is done and errors can be made
Instant feedback
Corrections made before defects occur
4 components of ZDQ

Poka-Yoke
a method that uses sensors or other devices to catch errors that may pass by operators or assemblers
Poka-Yoke
Poka-yoke an Point of Origin Inspection are what type of approach
Proactive approach
Poka-yoke and Informative Inspection are what type of approach
Reactive approach
this Poka-yokesystem approach shuts down the process when an error occurs
Control approach
This type of Poka-yoke system approach signals the operator to stop the process and correct the problem
warning approach
This primary method of Poka-yoke functions by detecting whether a sensing device makes contact with a part or object within the process
contact method
photoelectric switches can be used with objects that are translucent or transparent upon the need
this switch makes contact with a metal barb sensing its presence
limit switch
This primary method of Poka-yoke functions is used when a fixed number of operations are required within a process or when a product has a fixed number of parts that are attached to it
counting method
This primary method of Poka-yoke functions uses sensors to determine if amotion or a step in a process has occurred
motion-sequence method
these devices work by physically touching something
physicalcontactsensors
this switch is used to physically detect the presence or absence of an object or item-prevents missing parts
touch switch
these devices work by using energy to detect whether or not an defect has occurred
energy sensors
these sensors signal the operator that there is a problem using colors, alarms, lights to get the workers' attention
