Closed-Loop
Corrective Action
Closed-Loop Corrective Action: Overview
From Lean Enterprise: A Comprehensive Overview, one-day workshop
presented on 12 February 2003
-
Central role in driving continuous improvement
-
Assure project closure
-
Standardize the change; hold the gains
-
Best practice deployment
-
We cannot overemphasize the importance of following through on every problem
and proactive improvement project.
-
Corrective action is required by ISO 9000.
-
Lack of follow-through will undermine employee confidence in the program.
-
Example: TOPS-8D gets to 2D or 3D
-
Follow-through on every project will encourage employee participation.
-
Many events can initiate a corrective action or proactive improvement.
-
Quality: scrap, rework, or field failure
-
Equipment downtime
-
National Semiconductor, Ford River Rouge: no such thing as a "minor" equipment
stoppage
-
ISO 9000 nonconformance
-
Employee-initiated hiyari (scare report). A hiyari can apply to anything
an employee or self-directed team doesn't think is right.
-
Quality
-
Safety
-
ISO 9000 (potential nonconformance)
-
Employee-initiated proactive improvement
-
Kaizen blitz
-
Any appropriate procedure may be used.
-
Plan, Do, Check, Act (PDCA)
-
Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control)
-
The modern Ford Motor Company's TOPS-8D (Team Oriented Problem Solving,
Eight Disciplines)
-
I recommend this as more versatile than Six Sigma's DMAIC. It can be applied
to almost any improvement activity.
-
TOPS-8D's containment step (3) can be omitted for proactive improvement
projects.
Team-Oriented Problem Solving, 8
Disciplines (TOPS-8D)
-
Form an appropriate cross-functional team.
-
The team should include a champion who has the resources and authority
to implement the team's solution.
-
Define the problem.
-
Contain the problem.
-
Protect the customer from the problem. This step can be omitted when 8D
is used for a proactive improvement because there is no "problem" (like
defective parts).
-
Identify the root cause.
-
Select a permanent correction.
-
Implement the corrective action and verify its effectiveness
-
Make the change permanent (standardization).
-
Also share the solution with similar operations. This is best practice
deployment.
-
Recognize the team's achievement
-
An advantage of a kaizen blitz is that it frequently provides "instant
gratification" in the form of easily-observable results.

Quality
Action Reporting (QAR) from Stochos
"The QAR incorporates all types of Quality issues
(Customer,
Vendor, In-Process, Safety, Quality Audit, etc.) into a closed-loop
system
that requires action from all appropriate personnel."
"The QAR tracks the following steps; Initiation, Notification to the
Responsible Party, Disposition of Materials, Disposition Sign-off, Root
Cause Analysis, Corrective Action Definition and Sign-off, and
Verification
of Corrective Action Effectiveness."
Specific benefits:
Issues cannot "fall between the cracks."
Information sharing between management and the shop floor
Elimination of paperwork
CATSWeb from AssurX
Corrective Action and Tracking System
- "CATSweb is a Web-based Corrective Action Tracking System
designed to solve
problems faster and maintain ISO 9000 standards."
- "Use CATSWeb for any number of applications, such as
tracking and managing
manufacturing nonconformances, customer complaints, supplier returns,
audits,
accident reports, chemical spills, health & safety issues, etc."
- "Extensible to Suppliers, Customers, and Business
Partners."
- Customizable forms
- It makes sure issues don't "fall through the cracks."
Everest from Lynksoftware.com
- "Supports quality requirements for ISO, QS, JCAHO, FDA and more"
- Includes past-due notices for required actions
TIPQA from TipTech.com
"automates a formal, closed loop
corrective action / preventative action system for resolving quality
problems encountered in the course of normal operations. CA documents
the history of corrective actions from request through follow-up and
closure including the Failure Reporting and Corrective Action System (FRACAS)."
