PLAN THE SCHEDULE
• List all the 8 steps in the PDCA cycle.
• Indicate the expected time frame.
• Use the milestone chart.
PLAN
Dr Ibrahim Nor 5
GRASP THE CURRENT STATUS
Obtain and review data using checksheet.Study the effects of the problem from various perspectives.Present available data in graphs, and Pareto charts.PLAN
Dr Ibrahim Nor 6
SET THE TARGET
• Indicate clearly the statement of result to be achieved.
• Target must be reasonable and realistic.
• Use SMART concept.
PLAN
Dr Ibrahim Nor 7
ANALYSE THE CAUSE & DETERMINE CORRECTIVE ACTION
• Prepare cause and effect diagram.
• Prepare hypothesis and verify most probable causes.
• Determine corrective action.
PLAN
Dr Ibrahim Nor 8
IMPLEMENT CORRECTIVE ACTION
• Take immediate action by following exactly as planned.
• Collect data on results and record any deviations.
• Provide adequate training.
DO
Dr Ibrahim Nor 9
EVALUATE THE RESULT
• Check the effect of the corrective action.
• Compare results with target
• Use paired Pareto Chart.
CHECK
Dr Ibrahim Nor 10
STANDARDISE THE PROCESS
• Document as standard operating procedure (SOP).
• Set parameters to monitor and control the successful process.
• Ensure appropriate training on the new methods.

CHECKSHEET
• A Checksheet is used to gather relevant data in a simple, standardised format. The use of checksheet makes the collection of data easier and more systematic.

CAUSE AND EFFECT DIAGRAM
• The Cause and Effect diagram helps us to find out all possible causes, to sort them out, and to organise their inter-relationship. Typically, the causes are brainstormed in a free-flowing session.

PARETO DIAGRAM
• A Pareto diagram is constructed to show the relative importance of different categories in a process. The vital few is separated from the trivial many. This will ensure that focus is made on the what is important.
