  2. The system of quality is prevenion
  3. the performance standard is zero defects

41
A3
Tells a story on a single sheet. Based on PDCA, good for small non-complex problems
42
Overall Equipment Effectiveness (OEE)
Availability, Performance, Quality Availability is hours of operations minus planned downtime Performance is actual operating time Quality represents the percentage of good units produced
43
OEE calculation
Availability x Performance x quality A: Actual operating time / planned available time P: Actual performance time / actual operating time Q = total units - rejects / total units
44
Standard Work includes
Standard Time, inventory, and sequence
45
Takt Time
Matches production to demand Available minutes / Customer demand = X min per unit
46
Hoshin Planning
Company develops up to 4 vision statements to where the company should be in 5 years
47
8 Ps of Lean Thinking
Purpose process people pull prevention partnering planet perfection
48
Value added is defined as
the customer recognizes value it transforms the product it is done right the first time
49
andon
vsual feedback system (traffic lights)
50
A3

51
Gemba
management walkaround
52
heijunka
production scheduling purposely producesin much smaller batches by sequencing product within the same process. leads to reduced lead times
53
hoshin kanri
policy deployment: Company (strategy) middle management (tactics) operations floor (action)
54
Jidoka
autonimation
55
Kanban
kanban cards are a visual indicator the quantity needs to be replenished once the min level is reached
56
OEE
overall equipment effctiveness AxPxQ
57
Poka Yoke
Mistake proofing through prevention
58
Single Minute Exchange of Dies (SMED)
Rapid changeover that should take less than 10 minutes
59
Standard Work
interaction between man and machine in producing a part. 3 components: standard time standard inventory standard sequence
60
KPI
Key process indicator - quantifiable measurement, which is agreed to beforehand, that reflects the critical success factors of a department
61
Takt Time
purpose is to match production with customer demand.
62
theory of constraints
focuses on the weakest link. 5 steps: identify exploit subordinate elevate repeat
63
Drum-buffer-rope
to avoid long lead times and WWIP, all system processes shld be slowed down to the speed of the slowest process
64
TPM
total productive maintenance. equipment must be reliable, preventative maintenance
65
Waste (Muda)
overproduction motion waiting inventory transportation defects overprocessing skills unused ------- perfection employee demotivation
66
Spaghetti diagrams
graphic tool used to show the flow or path that people, products or paperwork take during a normal operation
67
value stream map
series of activities an org performs, such as order,d esign, produce, and deliver products and services
68
3 components of value stream
1. flow of materials from receipt of supplier to delivery of finished goods/services to customers 2. transformation of raw materials into finished goods or inputs into oututs. 3. flow of information required to support the flow of material and transformation of goods and services
69
value stream map is also known as
value chain diagram
70
Design for Six Sigma
customer driven to deliver faster, higher quality consumables
71
only about ____ of new products launched in all industries are successful
60%
72
DFSS vs Six Sigma
DFSS is more proactive than reactive, applies to new consumables, focuses on marketing, R&D, and design. Starts earlier to develop the process predicts design quality up front
73
DFSS methodology: IDOV
Identify - VOC, QFD, FEMA, Benchmarking Design - CTQ, identify functional rqmts, develop alternatives, evaluate and select Optimize - process cape info, stat tolerance, robust design, and verious SS tools Validate - test and confirm
74
two common DFSS methodologies
IDOV and DMADV
75
DMADV
Define proj goals Measure and determine customer needs and specs Analyze the process options to mee customer needs Design the process details Verfy and validate the design performance
76
DMADV design imperatives
Manufacturing maintainability environment robust usability scalability safety
77

risk
80
Design Failure modes and effects analysis (DFMEA)
