Classify initiatives by ROI as Stop, Continue or Invest

About this exercise

Compute ROI for each initiative as benefit divided by cost, rounded to one decimal and written like 1.4x. Then decide: Stop if ROI is below 1.0x, Continue if from 1.0x up to and including 2.0x, Invest if above 2.0x. Use the latest figures. Output a table with the header Initiative | ROI | Decision, one row each in the order listed, then the exact line: Counts: Stop N, Continue N, Invest N, with the numbers. Plain text, under 110 words.

Common mistakes when you ask AI for this

• Using the uncorrected benefit. The AI computes 1.7x for the partner portal. Try: Say: "Use the latest figures, including Finance's correction."
• Boundary mistakes. The AI marks 1.0x as Stop. Try: Say: "Continue is from 1.0x up to and including 2.0x."
• Using the old deck threshold. The AI uses 1.5x. Try: Say: "Apply only the Stop, Continue, Invest rule given."
• Wrong count line. The AI leaves it out or miscounts. Try: Say: "End with Counts: Stop N, Continue N, Invest N."
• Wrong table. The AI reorders rows. Try: Say: "Exactly this header and five rows in the listed order."
• Markdown. The AI bolds decisions. Try: Say: "Plain text."
• Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each part instead, for example: "each line under 15 words."
