5. Continuous Improvement
Establishing adequate processes for measurement, analysis and improvement within the QMS as related to correction and/or corrective action for nonconformities or preventive action for potential nonconformities of systems, processes or products

6. Measurement System
Is an essential part of continuous improvement system
If you cant measure it, you cant improve it
Measure the vital few
Scorecard, dashboard metrics
Financial measures
Performance measures
Process cycle time
Effectiveness of new product development

8. CAPA the Reactive Approach
The concept of corrective action and preventive action has been incorrectly interpreted to assume that a preventive action is required for every corrective action.
Preventive action is taken to prevent occurrence
Corrective action is taken to prevent recurrence

9. Preventive Action
Action to eliminate the cause of a potential nonconformity or other undesirable situation
There can be more than one cause for nonconformity

10. Corrective Action
Corrective Action:
Action to eliminate the cause of a detected nonconformity or other undesirable situation
There can be more than one cause for nonconformity
Corrective action is taken to prevent recurrence whereas preventive action is taken to prevent occurrence
Correction Action:
Action to eliminate a detected nonconformity
A correction can be made in conjunction with corrective action
Corrections can be, for example, rework or re-grade, fix

The 1 10- 100 Rule
18. Cause and Effect
Deeply in love I fell.. Deeply in love I was... when my eyes eyed your eyes...your eyes were the cause.
Part 1:The Effectis what we see or experience with our senses
Part 2 :The CauseThe reason why a particular element of a design or process resulted in a failure mode.

19. Symptoms and Causes
Symptoms = Effects: are the signs or results of a failure but not the root cause
Causes levels:
First level causes: the direct lead to a problem
High level causes: the highest level cause is called the root cause

20. Examples
Sep 12, 2008 Metrolinkaccident 25 fatality and 135 injuries
Symptom: Metrolink train collided head-on with Union Pacific freight at combined speed of 83 mph
First level cause: Metrolinkengineer ran through red stop light and into a path of a Union Pacific freight train because he was text messaging.
High level cause: Metrolink founders made a decision two decades ago to agree to share tracks with two giant freight lines, and refused to install an automatic breaking system

28. When to Use RCA
Problem that exceeded the established threshold
Repeated occurrence
One time occurrence that have high risk
Within your span of control

31. Root Cause Analysis Methodology
Define the problem
Analyze the problem root causes
Identify effective solutions
Implement the best solutions

33. Why Problem Definition is Important?
It focus everybody on the same problem
It establish the value of the problem
It communicate the problem impact on the organization
Problem statements it focus on facts only
Qualitative
Quantitative

34. Problem Definitions Elements
Define the process input (X) and desired output (Y) qualitatively and quantitatively
What: Primary effect (noun verb)
When: Relative time of the primary effect
Where: Relative location in system, facility, or component
Significance: Why you are working on this problem?
June 10
34
Tarek Elneil
35. Problem Definition: What
The problem would be defined according to which of its aspects has the biggest impact on the organization
Example:
Customer loss
Down time
Backlog
June 10
35
Tarek Elneil
36. Problem Definition: When
Include both chronological time and relative time
Example:
Feb 20, 2009
At 2:30 PM
First day back to work
While preparing to leave for the day
After the completion of step xx
June 10
36
Tarek Elneil
37. Problem Definition: Where
Start with the broad area description and step down in details until you have described exactly where the problem has occurred
Example :
Camarillo facility
Warehouse
Cold storage
Shelf #12

Tarek Elneil
38. Problem Significance
Actual vs. potential impact: In examining the problem significance we look at both actual and potential impact.
Example
Customer complaint of a bad kit might worth $1000, but potential losing a $50,000 contract.
June 10
38
Tarek Elneil
39. Quantifying Problem Significance
It help to answer 3 questions
Should we continue with the investigation?
How much time should we spend on the investigation?
How much of resources (people and money) should we utilize to investigate and solve the problem?

  • Example of significance statement:

40. Potential loss of $1500 worth of raw materials 41. Twice this month 42. 2 weeks delay in customer order June 10
39
Tarek Elneil
43. Whats Not Problem Definition
Who: diverts attention from the problem, and if it is important it will be discovered during the investigation. If it is necessary to mention who then mentionthe title (Analyst, Security, Manager, Technician, etc)
Why: this is what the investigation is all about
June 10
40
Tarek Elneil
44. Look for Causes in Action & Condition
Focus on causes
Ask what condition (input) had to be in place for the action to cause the effect (output)?
For each conditional cause must have an action cause
Action cause can have more than one condition
June 10
41
Tarek Elneil
45. Analysis
Action causes are momentary, they act as the catalyst for the casual relationship
Conditions causes exist over time. Condition provide the best opportunities for solutions

48. Stop
Cause and effect charts can potentially extend infinitely into the past. Use stop at the end of the cause chain if there is no value in pursuing causes further
Injury
Leaking
Valve
Fall
Wet Floor

49. Start

Tarek Elneil
50. Solution Significance
The magnitude of the problem determines the amount of effort to direct toward a solution. Weight the cost of the problem and efforts verses the cost and efforts of the solution
If the problem is very costly and the solution or the group of solutions cost less, then it is worth implementing
June 10
47
Tarek Elneil
51. Solution Selection
Establish Solution Criteria
Prevent recurrence
Comply with requirements
Be within control
Does not create other problems
Meet organizational goals and objectives
Develop solution matrix
Challenge all solution ideas in the list against criteria for viable solutions

53. The Most Effective Solutions
There is more control over conditional than actions causes
There should be far more conditions than actions in the chart, thus creating far more solution opportunities
Solutions for conditional causes are usually more reliable than solutions for action causes
Implement and control the solution(s)
