2. Training agenda
What is and how to describe a PROBLEM?
Premises and directions for problem solving
Problem solving techniques
Problem solving steps
Problem solving tools
Correction / Corrective action / Preventive action
3. = discrepancy observed between actual and expected result
Problem
SYMPTOM vs. PROBLEM
Symptom
= what went wrong with what
Problem description
= detailing the problem in quantifiable terms:
- What?
- Where?
- When?
- How big?
4. Premises for problem solving
Understanding the problem
Availability of technical know-how on affected
process/product
Availability of resources
5. Directions to follow
Occurrence
why did the problem occur?
Non-detection
why was the problem not detected?
6. Problem solving techniques
= proactively reduces the probability of problems
occurence
= approaches and solves problems: identification, correction
and elimination
= control and continual improvement of processes
FMEA

2. Problem description
3. Correction
4. Root cause(s) analysis
5. Establish corrective actions
6. Implement and validate corrective actions (CA)
7. Check CA efficacy and establish preventive actions (AP)

11. Correction / Corrective action / Preventive
action
correction
= action taken in order to eliminate the symptom
corrective action
= action taken in order to eliminate the root cause
preventive action
= action taken in order to avoid root cause recurrence
