II. The RCCA Process
Step 1: Triggers for Engaging RCCAs
RCCAs can be triggered by:Customer or Vendor request
Internal Quality or Yield Issue
Defect Rate
Special Request – e.g. manufacturing,reliability engineering, supplier quality.
Page 19
Initiating the RCCA
Step 2: Initiating the RCCA Process –
1. Describe the issue at hand, work on clarity of Problem definition.
2. Systems / Environment considerations.3. What did the customer (internal or external)
perceive in terms of a quality and reliable product or service?
Page 20
Creating a Problem Statement
Problem Statement When creating a Problem Statement, you need be
specific while describing the problem.
Quantify the problem when ever possible.
Include any Gap that exist between what the Customer expected, versus what they actually received!
Page 21
Step 3: Performing RCCAs1. Description of the problem, history, and systems environment
2. Problem Statement including the gap between whatthe customer expected vs. what they actually received.
3. Discuss/brainstorm contributing causes to the areas of:People, Systems, Policy and Procedures
4. Vote on Major Limbs using “star” votes. # of votes = 5/person
5. Gain consensus by selecting one or two key limbs.
6. Peel the Onion on major cause variable(s) with the “5 Whys”

Exercise: Performing an RCCA – Case Study� Instructions: Please read the following scenario, and then use the RCCA Agenda on the previous
page to perform your RCCA. Your instructor will have you break into groups for completing this exercise.
� Cast of Characters:
Betty Joe Underwood, Interface Designer, for Soft ID, Inc.Mary Mathieson, Escalation Mgr., Computer Accelerators, Inc.John Lickstein, Software Development, Computer AcceleratorsPatrick Evangelical, Program Manager, Strong Widgets Int’l.
SCENARIO:Computer Accelerators is a world renowned developer of “Links” operating systems, a virtual thin client that is capable of running a variety of enterprise level software applications for small business applications. Strong Widgets has purchase thecomplete suite of Software from Computer Accelerators, including a special GUI provided with the Suite originally built by Soft ID, Inc. Strong Widgets experienced normal growth and sales of their photo ID Widget product for the first half of FY’04.
� However, now due to a broadened marketplace, Widgets has been taking on hundreds of more interested customers every week, and think that there total number of users hitting their web-site has exceeded 225,000.Intermittent failures in the App. occurred, which prompted Patrick Evangelical to submit an Escalation. Mary designated the escalation as yellow upon entering into Computer Accelerators tracking database.
The GUI produced by Soft ID was simulated to test reliably at 100,000 users by Computer Accelerators Operating Systems Test personnel. Recently, due to possible both the scalability issue as well as an interoperability failure inside the GUI, Computer Accelerator’s OS is now hanging for indeterminable amounts of time, causing Strong Widget’s to reboot the system for their web-site applications to become once again, and again “Available.” This has moved the Escalation from yellow to red, which necessitates an RCCA.
� Patrick, taking a full head of steam, follows up on the already escalated issue within Computer Accelerators, and contacts Mary Mathieson to perform an RCCA on this heated issue.
Question: Who do you think Mary bring to the RCCA session?Please answer this question, and then in your groups, perform an RCCA using the Facilitation Agenda.
Page 28
Exercise: Performing an RCCA
Perform an RCCA using the Facilitation Agenda:

Pareto ChartsPareto Analysis (The 80-20 effect)
Value of Pareto Analysis: When you identify the “vital few” you improve your ability
to identify the root causes to the majority of the problems.
By solving the largest problem in many cases, decreases the overall percent defective or the product or service.
Cost benefit of product can be determined with the assistance of Pareto Analysis.
Solving major problems often reduces or eliminates the minor problems (noise).

IV. Corrective Action Quality Tools
Preface: You’ve learned how to perform RCCAs and how to integrate Problem Solving Methods. “Corrective Action Quality Tools” help hone and reduce variation to your existing processes.
This section will discuss the following:1. Variation – Abnormal and Normal causes of variation2. Data Collection Do’s and Don’ts3. Variables and Attribute Control Charts4. Approaches to improving Quality Service
Page 41
Variation – Abnormal and Normal Causes
• Normal causes of variation result from the problems in the system as a whole.
• Abnormal causes of variation result from special problems within a system.
Normal cause Abnormal causecommon specialrandom non-randomsystematic localexpected irregularunidentifiable identifiable
Page 42
Sources of Variation
Sources of Variation: People lack of training, shifting priorities,
motivation, work habits
Machinery obsolete, inadequate, difficult to use
Materials contamination, faulty, expired, make-shift
Environment temperature, humidity, poor lighting, poor working conditions
Measurement inaccurate or not precise, out of calibration
Methods inappropriate, unclear methodology, inadequate documentation
Page 43
Measures of Variation Variation: Spread, dispersion or scatter around
the Central Tendency, e.g. the mean or average.
Range: Difference between the largest and smallest value.
Standard Deviation ( σ or S ): A measure of variance.

Attribute ControlsAttribute Control ChartsAttribute Control Charts consist of primarily three basic types of
charts following the binomial and poisson distributions:
np Charts - used for monitoring the # of defects per samplewhen the sample size is constant, for example, n = 50.
p Charts - can be used either with a constant sample size or variable sample (n) size. Variable control limits or average n size control limits may be imposed.
c Charts – is applicable for the number on defects per sample unit, e.g. # of defects on a car. Sample unit size is constant.
Page 52
np Chart (Attribute Data) Procedure� Steps for creating NP Chart in Excel:
1. List in horizontal rows your data and sample size as shown on previous page.
2. Next, Create average column, and Upper Control Limit column based on 95% confidence. Hint: you will need to calculate the standard deviation for NP.
3. Create fourth column with Limit included for every point
4. Use chart wizard to create your control chart.

Bonnie Small’s Rules (AT&T)
Bonnie Small's guidelines for interpreting control chart data:
• Points beyond the control limits usually indicate:- The process performance is sporadic- Measurement has changed (inspector, shift, gage, etc.)
• Runs indicate a shift or trend. Runs include:- 7 points in a row on one side of the average- 7 points in a row that are consistently increasing or decreasing
• Non-random patterns may indicate:- The plot points have been miscalculated or misplotted.- Subgroups may have data from two or more processes.
