Managing Motor Fleet Safety Programs: Training for the Safety Director Unit 3 – The Quality Approach to Safety Programs NATMI © 2014
Unit 3 Objectives Explain why safety directors need to think about safety as part of an overall system Explain why it is important to use data to identify the root causes of problems Distinguish between common cause and special cause variation, and determine how to respond to each kind Describe how control charts can be used to analyze safety data Explain the key quality management approaches that are important to implementing changes to solve safety problems NATMI © 2014
Quality Management Approach 1. Collect data 2. Identify root causes of problems 3. Develop appropriate solutions 4. Plan and make changes NATMI © 2014
The Organization as a System of Processes Processes have their own inputs, steps, and outputs Processes can be simple or complex Processes are interrelated NATMI © 2014
Success Depends on All Components Changing any process affects outcome Optimization is achieved through cooperation not competition NATMI © 2014
Managing a System Recognize importance of interrelationships Consider process inputs and steps, not just outputs NATMI © 2014
Variation Every process has variation Reduce variation to improve efficiency To reduce variation you must understand the cause of the variation NATMI © 2014
Understanding Variation NATMI © 2014 J FM AM JJ AS O ND Incidents Per Month 30
Common Cause Variation Caused by inputs that are always present in a particular process NATMI © 2014
Special Cause Variation Caused by unusual circumstances, where the inputs are not usually part of the process NATMI © 2014
Actions to Control Variation Study the overall process OR Study only the incident and events surrounding the incident NATMI © 2014
Controlling Variation from Common Causes NATMI © 2014 J FM AM JJ AS O ND 10 5 Incidents Per Month A. Study overall process OR B. Study specific incident
Controlling Variation from Special Causes NATMI © 2014 A. Study overall process OR B. Study specific incident J FM AM JJ AS O ND Incidents Per Month 30

A Process in Statistical Control Predictable and stable Basis for prediction NATMI © 2014
Sample Control Chart NATMI © 2014 J FM AM JJ AS O ND 10 5 Upper Control Limit Lower Control Limit Average (Mean)
Purpose of Control Charts Distinguish between common and special cause variation Look at how process is performing Predict future process performance NATMI © 2014
Is This Process in Statistical Control? - 1 NATMI © 2014 J FM AM JJ AS O ND 24 6 Upper Control Limit Lower Control Limit Average (Mean)
