[Verse 1]
Quality's not grade, let's make this clear
Quality meets requirements, grade shows features here
A Rolls-Royce is high grade, but quality's the test
Does it meet what's promised? That's the quality quest
[Chorus]
Plan and manage quality right
Prevention, Appraisal, keep costs tight
Internal, External failures too
Cost of Quality guides what we do
Plan-Do-Check-Act, continuous flow
Seven tools to help quality grow
[Verse 2]
Cost of Quality has two main parts
Conformance costs protect our hearts
Prevention stops defects before they start
Appraisal finds them, plays its part
[Chorus]
Plan and manage quality right
Prevention, Appraisal, keep costs tight
Internal, External failures too
Cost of Quality guides what we do
Plan-Do-Check-Act, continuous flow
Seven tools to help quality grow
[Verse 3]
Non-conformance costs when things go wrong
Internal failure before we ship along
External failure after delivery's song
Both cost more than prevention strong
[Bridge]
Fishbone diagrams show cause and effect
Flowcharts map process, what to expect
Check sheets collect data we need
Pareto shows eighty-twenty indeed
Histograms display the distribution
Control charts track with contribution
Scatter plots show correlation's way
Seven tools guide us every day
[Verse 4]
Upper Control Limit, Lower too
Mean line runs between the two
Rule of Seven points in row
Special cause, we need to know
[Verse 5]
Statistical sampling saves us time
Inspections catch defects in line
Audits check our process flow
Kaizen helps improvement grow
[Chorus]
Plan and manage quality right
Prevention, Appraisal, keep costs tight
Internal, External failures too
Cost of Quality guides what we do
Plan-Do-Check-Act, continuous flow
Seven tools to help quality grow
[Outro]
Definition of Done in Agile way
Quality metrics guide our day
Management plan keeps us on track
Quality forward, never back
