What is CAR?
• The purpose of Causal Analysis and Resolutionis to identify causes of defects and otherproblems and take action to prevent them fromoccurring in the future. üMay also be performed on problems
unrelated to defects• Cycle time• Improvement proposals• Dynamic systems models• New business directives

CAR: Key ElementsDefect

Main Questions to Answer:• How could I have prevented this defect?• How can the process data enable me to prevent similar
defects?

Key Considerations
• CAR Quality Management Approach
ü Defect prevention is a Customer Focused pro-activeapproach
ü Find points of failure and correct or avoid them• Positive impact on what you are building or how you are
building it must be a Value Added Activity• Reliance on detecting defects after they have been
introduced is not cost effectiveü Opportunity to share lessons learned on problem areas
• Harness project experience to determine defectsimilarities – common classifications
ü CAR shifts the organizational emphasis from discovery toprevention of defects

Hybrid Implementation Approach
• Parallel continuous improvement on CARimplementation, while pursuing an overall StageRepresentation implementation strategyüEnables immediate pay off on ROIüEnsures early development of a data collection
planüPromotes awareness at an earlier level in the
overall process improvement effortsüPrevents rework in later stagesüProvides systems wide view of operational
readiness

Business Reality• New “watch words” are speed, agility, collaboration, and innovationü Lifecycle timeframesü Cross functional teamsü Rapid response
• Current business environment is characterized by rapidly changingtechnologies within an extremely competitive market
• Customers demand more functionality at a lower price and rapidimplementation of any new capability to satisfy their changing businessdemands
• Focus is on performance; however, need exists for an immediate ROIthat is demonstrable to the customer
• Difficult to establish a organization as an technology market leader andeven more difficult to maintain it as a top-performing organizationü One that performs better than its competitors from both technical
and business perspectives

The Quality Paradigm
• Current Mindset: “You get what you pay for!”• Quality Management when properly executed will help to reduce
costs. The higher the quality, the lower the operating costs.• Key component to executing a successful quality management
program is to ensure a committed, proactive approach to preventingproblems is achieved.ü Bottom line: All defects can be traced to a cause, and with
proper application of quality management principles, can beeliminated.
Deming quote: “Defects are not free. Somebodymakes them and gets paid for making them.”

When will it change?
• According to the U.S. Defense Dept. and the SoftwareEngineering Institute, there are typically 5 to 15 flaws in every1,000 lines of code
• Tracking down each bug eats up about 75 minutes, accordingto a five-year Pentagon studyü Fixing them takes two to nine hours each
• On the outside, that's 150 hours, or roughly $30,000, tocleanse every 1,000 lines

Probing Questions• What are the business goals you'd like to hit this
year?• How are you communicating business goals and
objectives throughout the company?• How are you tracking progress in meeting those
goals?• What must I do to keep a true customer focus
throughout my workday?• What must be done to harmonize all systems and
processes?• What must I do to achieve detailed thinking on a
continuous basis?• How can I create rapid solutions for prevention,
while thinking at a slower rate?• What must I do to understand the consequences
of any actions continuously throughout myworkday?

Growing the CAR MeasurementProcess
• Iterative analysis process• Focus on value-added performance metricsü Performance must be measured from the onset of any
initiativeü Should be an integral part of the company operationsü Breakeven point of quality efforts must be considered, i.e.,
cost benefit analysis at any level of implementation
** Most performance initiatives are hampered by theunavailability of objective quality data

CAR Measurement at All Levels
Projects collect defect data, as available. Establishment of metricstraceability to business drivers. Establishment of CAR principles.Establishment of data collection and analysis mechanism. Trainingconducted on defect prevention and root cause analysis
Projects collect defect data. Different projects may use differentdefinitions. Infrastructure enforced via PPQACAR filter applied to Measurement and Analysis Process Area
There are consistent definitions from one project to the next.Defect data are collected across the organization. Causal analysesare conducted in a consistent manner.
Defect causal analysis is based on the principles of statisticalprocess control.Actual measurements are compared to expected values ofmean and variance.
Continuing improvement is based on business objectives, marketdemands and cost-benefit analysis.

Barriers to CAR Implementation
• Process-based culture is immature
• Process Focus is limited; nosupporting infrastructure
• Translation of “BusinessDrivers” to measurableobjectives
