CAP – Do Cycle

The Key Tool for Executing  Focused Improvement

• Check – Observe, Collect Data
• Analyze – Determine Root Cause
• Plan – Formulate Actions
• Do
  • Implement Plan
  • REVIEW – Monitor results and return to Check

Cap-Do form can be found here.

CAP-Do: The Check Phase

1. Identify the Problem
   • “A state of difficulty that needs to be resolved”
   • “A question raised for consideration or solution”
2. Understand the Ideal Situation
3. Identify the Phenomenon
   • “Whatever, in matter or spirit, is comprehended by observation”
   • “Any state or process is known through the senses rather than by intuition or reasoning”

 Phenomenon Means: 

• Observing the facts with our own
  eyes & all senses
• The facts without presumption

CAP-Do:    Check Step 1

1. Identify the Problem
   • “A state of difficulty that needs to be resolved”
   • “A question raised for consideration or solution”
2. Understand the Ideal Situation
3. Identify the Phenomenon

Check Step 1: Identify the Problem

• Collect Data
• Go to the “actual place”
  • Observe
  • Take Photographs / Videos
  • Interview
• Collect Data*
  • Assemble all available related data from Loss Tree Analysis

CAP-Do:    Check Step 2 Understand the Ideal Situation

Machine

• Equipment Sketches
• Operational principles & model

Material

• Material samples

Man & Method

• Flow charts of the process
• Forms and procedures

Check Step 3: Identify the Phenomenon

5W’s 1H* (Define the problem, show loss data)

• What, When, Where, Who, Which, and How.
• Requires information collected in CHECK Steps 1 & 2 to complete the 5W1H form and identify the “phenomenon”.
• If there is not enough data from CHECK Steps 1&2, the 5W1H must be paused to get the data.
• The cause is NOT assigned/implied in the Phenomenon statement.

What:

• What thing or product did you see the problem?

When:

• When did the problem occur?

Where:

• Where did you see the problem? (Line/Machine/Location)
• Where on the work or material did you see the problem?

Who:

• Is the problem related to skill? (Skill dependant or independent)

Which:

• Which trend (pattern) did you see the problem have?
• Is the trend random or is there a pattern?

How:

• How is the state different from a normal condition?

CAP-Do: The Analyze Phase

• Determine Root Cause
  • 5 Why (Why-Why)
  • Principle of Operation
  • SEND Analysis
• Formulate Possible Actions

CAP-Do: The Plan Phase

• Review and Prioritize Possible Actions
• Short and Long Term Actions
• Assemble Required Materials
• Write OPL’s
• Schedule Work
• Create OPLs

CAP-Do: The Do Phase

• Safety Comes First
• Implement Actions
• Review
  • Observe Results
  • Hold the Gains
• Return to Check
