[Hook] Garbage in— Vision out. Turn the missing numbers Into something we can shout. [Verse] Ninety-seven percent complete, The progress bar looks clean. No one asks which seven teams Disagree on what it means. Sales uploads a monthly file, Finance sends the year. Support removes the angry words So sentiment looks clear. Victor writes "predictive growth" Across the sprint review. Aisha says, "The labels drift." Victor shrugs: "That's Data Science." [Chorus] Garbage in, vision out, Polish every open doubt. Garbage in, vision out, Give the board a line to quote. When the inputs fall apart, Put a logo on the chart. [Verse] One segment means "enterprise," Another means "has paid." A churn event is anything The previous analyst made. We train on stale November, Then forecast through July. A warning turns from amber When the threshold moves up high. The sprint board says "Model ready." The model has no name. The acceptance test reads only: "Results support the business case." [Chorus] Garbage in, vision out, Polish every open doubt. Garbage in, vision out, Give the board a line to quote. When the inputs fall apart, Put a logo on the chart. [Heavy Breakdown] Bad labels. Good branding. Red warning. Green guide. [Bridge] Aisha cuts the power down. "No claim without validation." Victor leans in: "Can we call it An optimisation instead?" [Build-up] Garbage in— The sequencer replies. Vision out— The fabrication motif climbs. [Final Chorus] Garbage in, vision out, Now the quiet error shouts. Every shortcut leaves a trace, Every guess acquires a face. If the inputs fall apart, The failure starts before the chart. [Outro] The progress bar reaches one hundred. Nothing underneath has changed.
