MichaelThank you for the extra slot on today's agenda. I will get straight to the point: my estimate for the data migration was too optimistic, and I want to correct it openly today — before the numbers correct it for me.Ich komme direkt zum Punkt: Meine Schätzung war zu optimistisch, und ich möchte sie heute offen korrigieren.
MichaelThe facts first. In March I estimated six weeks for the full migration. Today we are in week five, and roughly sixty per cent of the data has been moved. Realistically, we need four more weeks — ten in total.
MichaelLet me explain where my estimate went wrong, because the reasons matter more than the number. The first reason is the quality of the legacy data. I calculated with two weeks of testing — as we would say in German — in English: I allowed for two weeks of testing. In reality, cleaning the old customer records alone has taken three.„Mit zwei Wochen rechnen" heißt auf Englisch „to allow for two weeks" – nicht „to calculate with".
MichaelThe second reason: I planned with best-case availability. Our two key developers were booked at eighty per cent on this project. In practice, support tickets pulled them down to sixty — and I should have known that from the last two projects.
MichaelThe third reason — and this one is entirely on me — I treated the vendor's figures as facts. Their brochure promised a transfer rate we have never reached, and I never tested it before I built my plan on it.Dieser Punkt geht ganz auf meine Kappe: Ich habe die Herstellerangaben ungeprüft übernommen.
MichaelSo what changes now? The new estimate is ten weeks, and it is a conservative one: it includes a buffer of one full week, and it assumes the developers at sixty per cent availability, not eighty.
MichaelFor the launch, this means a shift of three weeks — from the fourth of November to the twenty-fifth. Marketing has already been informed, and the campaign can be moved without extra cost if we confirm the new date today.Für den Launch bedeutet das eine Verschiebung um drei Wochen.
MichaelWhat am I changing so this does not happen again? Three things. Every future estimate gets a range instead of a single number. Every figure gets a tested assumption behind it. And every estimate gets a second pair of eyes before it reaches this meeting.
MichaelI would rather stand here once with an honest correction than every week with a small excuse. My recommendation: we approve the twenty-fifth today, and I report progress against the new plan every Friday. Thank you — I am happy to take questions.Lieber stehe ich einmal mit einer ehrlichen Korrektur hier als jede Woche mit einer kleinen Ausrede.

Language notes
In this episode an IT team lead corrects his too optimistic estimate before the steering group: message first, then facts, three reasons, the new conservative number and the consequences. You learn the language of professional admission — and why "I calculated with two weeks" is wrong in English (level B2).
The admission first — before the numbers force it
Michael opens with the hardest sentence: "My estimate … was too optimistic." No backstory, no softening — "I will get straight to the point". The phrase "too optimistic" is deliberate: it names the error clearly but sounds more professional than "wrong" or "a mistake". His addition "before the numbers correct it for me" shows the principle behind it: report a misestimate yourself and you control the story; wait, and the story controls you.
The rechnen-mit trap: allow for, not calculate with
German "mit zwei Wochen rechnen" tempts a word-for-word "to calculate with two weeks" — but in English "calculate" describes the arithmetic itself, not the planning. The correct verbs are "to allow for two weeks", "to plan for" or "to expect". Michael corrects himself mid-sentence and even labels the trap ("as we would say in German") — an elegant technique when a Germanism slips out in a meeting.
Reasons, new number, consequences — the credibility chain
After the admission, Michael gives three precise reasons and explicitly owns the third ("this one is entirely on me"). Only that makes the new number credible: it is "conservative", contains a named buffer and rests on corrected assumptions. The close — three process changes and a weekly report — answers the question every steering group asks: why should we trust this estimate more than the last one?

Frequently asked questions
What language level is this episode for?
Level B2 (CEFR). The monologue uses precise project English (estimate, buffer, conservative, legacy data); all eight key terms are explained bilingually.
How do I admit in English that my estimate was wrong?
In five steps: admission first ("my estimate was too optimistic"), state the facts, explain the reasons, present a conservative new number with a buffer, and say what you will change ("every estimate gets a second pair of eyes").
How do you say "mit etwas rechnen" in English?
For planning: "to allow for" or "to plan for" ("We allowed for two weeks of testing"). For expectations: "to expect". The word-for-word "to calculate with" is a typical German error.
