Plan Do Check Act Reminder DMAIC is the flagship
When Would it Make Sense to Use PDCA?
5
Plan Do Check Act - PLAN Plan to improve your operations first by finding out what things are going wrong Identify the problems faced Come up with ideas for solving these problems
6
Plan Do Check Act – DO Do changes designed to solve the problems on a small or experimental scale first. This minimizes disruption to routine activity while testing whether the changes will work or not.
7
Plan Do Check Act - CHECK
Check whether the small scale or experimental changes are achieving the desired result or not.
8
Plan Do Check Act - ACT Act to implement changes on a larger scale if the experiment is successful. Abandon if not.

5Cs Clear Out: Separate the essential from the non essential
Configure: A place for everything and everything in its place. Clean and Check: Manually clean to spot abnormal conditions. Conformity: Ensures that the standard is maintained and improved. Custom and Practice: Everyone follows the rules, understands the benefits and contributes to the improvement. Not to be reprinted without the expressed written permission by SSD Global, Inc.

Severity Effect Criteria: Severity of Effect Defined Ranking Hazardous: Without Warning May endanger operator. Failure mode affects safe vehicle operation and / or involves noncompliance with government regulation. Failure will occur WITHOUT warning. 10 Hazardous: With Warning May endanger operator. Failure mode affects safe vehicle operation and / or involves noncompliance with government regulation. Failure will occur WITH warning. 9 Very High Major disruption to production line. 100% of product may have to be scrapped. Vehicle / item inoperable, loss of primary function. Customer very dissatisfied. 8 High Minor disruption to production line. Product may have to be sorted and a portion (less than 100%) scrapped. Vehicle operable, but at a reduced level of performance. Customer dissatisfied. 7 Moderate Minor disruption to production line. A portion (less than 100%) may have to be scrapped (no sorting). Vehicle / item operable, but some comfort / convenience item(s) inoperable. Customers experience discomfort. 6 Low Minor disruption to production line. 100% of product may have to be reworked. Vehicle / item operable, but some comfort / convenience item(s) operable at reduced level of performance. Customer experiences some dissatisfaction. 5 Very Low Minor disruption to production line. The product may have to be sorted and a portion (less than 100%) reworked. Fit / finish / squeak / rattle item does not conform. Defect noticed by most customers. 4 Minor Minor disruption to production line. A portion (less than 100%) of the product may have to be reworked on-line but out-of-station. Fit / finish / squeak / rattle item does not conform. Defect noticed by average customers. 3 Very Minor Minor disruption to production line. A portion (less than 100%) of the product may have to be reworked on-line but in-station. Fit / finish / squeak / rattle item does not conform. Defect noticed by discriminating customers. 2 None No effect. 1 Not to be reprinted without the expressed written permission by SSD Global, Inc.

Possible Failure Rates
Occurrence Probability of Failure Possible Failure Rates Cpk Ranking Very High: ³ 1 in 2 < 0.33 10 Failure is almost inevitable 1 in 3 ³ 0.33 9 High: Generally associated with processes similar to previous 1 in 8 ³ 0.51 8 processes that have often failed 1 in 20 ³ 0.67 7 Moderate: Generally associated with processes similar to 1 in 80 ³ 0.83 6 previous processes which have 1 in 400 ³ 1.00 5 experienced occasional failures, but not in major proportions 1 in 2,000 ³ 1.17 4 Low: Isolated failures associated with similar processes 1 in 15,000 ³ 1.33 3 Very Low: Only isolated failures associated with almost identical processes 1 in 150,000 ³ 1.5 2 Remote: Failure is unlikely. No failures ever associated with almost identical processes £ 1 in 1,500,000 ³ 1.67 1 Not to be reprinted without the expressed written permission by SSD Global, Inc.
25
Detection Detection Criteria: Likelihood the existence of a defect will be detected by test content before product advances to next or subsequent process Ranking Almost Impossible No known control(s) available to detect failure mode 10 Very Remote Test content must detect 60 % of failures 9 Remote Test content must detect 65 % of failures 8 Very Low Test content must detect 70 % of failures 7 Low Test content must detect 75 % of failures 6 Moderate Test content must detect 80 % of failures 5 Moderately High Test content must detect 85 % of failures 4 High Test content must detect 90 % of failures 3 Very High Test content must detect 95 % of failures 2 Almost Certain Test content must detect 99.5 % of failures 1 Not to be reprinted without the expressed written permission by SSD Global, Inc.

Remember Only the Processes that Directly Contribute to the Improvement Are Considered Value Add

Waste/Non Value Can Mean
Something to Reduce Something Redundant Something that does not Contribute to the main process In this case it set aside and not shown on the map Doesn’t mean “waste” in the traditional sense of the word

CONTROL CHARTS (SPC Charts)
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT CONTROL CHARTS (SPC Charts) "Control Chart” is the most popular and effective statistical tool for process control. It has a center line (CL) and upper & lower control limits (UCL / LCL). UCL Quality Parameter CL LCL 1 2 3 4 5 6 7 8 9 Sample No.

There are some seven (7) common types of control chart patterns.
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT There are some seven (7) common types of control chart patterns. 1. Natural (Random) 2. Cycles 3. Trends 4.Grouping or Strays 5. Sudden shifts in the level 6. Mixtures 7. Stratification
48
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT
NATURAL (RANDOM) : In this case there will be no systematic trends or patterns. Data points scatter randomly above and below the central line.
49
CYCLES: Short trends in the data that occur in
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT CYCLES: Short trends in the data that occur in repeated patterns so that the pattern becomes predictable or systematic.
50
TRENDS: Long series of points that lack a change of direction.
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT TRENDS: Long series of points that lack a change of direction.
51
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT
GROUPING / STRAYS: Grouping occurs when the data cluster together in a non-random pattern. Strays result from a single measurement that is greatly different from the others.
52
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT
SUDDEN SHIFT IN LEVEL: A sudden shift in level is shown by a change in one direction. A number of points will appear on one side of the control chart.
53
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT
MIXTURE: Un-natural length of the lines joining the points to create a "saw tooth" effect.
54
STRATIFICATION: un-naturally small fluctuations
STATISTICAL TOOLS FOR QUALITY IMPROVEMENT STRATIFICATION: un-naturally small fluctuations and an absence of points near the control limits

Common Attribute Control Charts
c Control Chart (Counting) How many times does an event happen? u Control Chart Count by units (units can be varying sizes) np Control Chart Number of defects units per sample p Control Chart Percentage of defects per sample
59
Common Variable Charts
Looking at the Variation in a Process Two Types: Variation Between Samples X charts Within the Samples R & S charts within the samples
