  1. LINE 01

    Two reports. Two numbers. One meeting.

    Everyone is sure, and nobody can show how theirs was built.

  2. LINE 02

    The dashboard is green. The business does not feel green.

    The number looks fine. The people closest to the work do not believe it.

  3. LINE 03

    We bought the AI. We cannot show what it changed.

    The tasks got faster. Nobody can point to the outcome that moved.

  4. LINE 04

    The decision was made. Nobody can say on what.

    The approval exists. The evidence behind it does not.

  5. LINE 05

    We have the data. We do not know what it can answer.

    Years of records, and no one has asked them a question worth asking.

  6. LINE 06

    Something is off. We cannot prove it yet.

    A cost, a customer, a market. You can feel it, and you cannot show it.

  7. LINE 07

    One spreadsheet runs the company. One person understands it.

    Everyone relies on it. Nobody wants to ask what happens when that person leaves.

  8. LINE 08

    We keep paying for something nobody can explain.

    It renews every year. Nobody remembers why, and nobody wants to be the one who asks.

  9. LINE 09

    We are about to bet on a number I do not trust.

    The date is set. The number is in the deck. You have not said anything yet.
