Or if you just want to inform management that more people won’t simply mean the work gets done much faster just give the example of “If takes 9 months for a woman to make a child, it doesn’t mean you can get 9 women and make a child in one month”
Management: “I don’t have time for theoretical discussions. Marketing says this releases in two weeks and you better get it done. Do you need more resources?”
Management: “I don’t have time for theoretical discussions. Marketing says this releases in two weeks and you better get it done. Do you need more resources?”
“It can’t be done in this time frame.”
“Should’ve come and asked the experts how long would it take before accepting marketing’s estimates”
“So either find us more time or chose what we’re going to drop for the release”
And yeah, I’ve used this. (Then again, I’m pretty senior and seen and done a lot)
