Approximately how many "man-hours" did it take to develop GTA 5?

Question

Game development

And in general, how many man-hours does it take to develop AAA projects?
p.s. just wondering!

Answer 1

1. We go to the job site, look at how long each employee works in the resume, i.e. his time that he works, his profile (UI, Artist, C ++ programmer, etc).
Let's assume that everyone has the same working day from 10 am to 5 pm, i.e. 7 hours and everyone works 5 days a week.
2. We google information on the Internet about the number of employees in the company (for example, there is such a thing on Habré) and for example there are 1000 of them. (Let's denote the number as workers).
3. We must understand that all people are engaged in one thing. For example: Sony makes cameras, TVs, and phones. That is, here we don’t know who is responsible for what and it’s impossible to calculate correctly, because there is no 100% guarantee that all employees make cameras, phones, and TVs together, so the company should only do one thing. In our case, only make games (we consider managers, marketers and other non-programmers).
4. We are looking for official information about how long the game was made, for example, it was made for a year (let's denote TimeForCreateGames).
5. Now we calculate: WorkersTime * Days * (TimeForCreateGames / 7) * Workers = 5 * 7 * (365 / 7) * 1000 = 35,000 * (365 / 7) = 1,820,000 hours. Let the error be 500.00 hours for viewing Toaster, Habr, etc and other needs. (Roughly speaking, 48 hours for one person)

PS In reality, days, hours, working days may differ, but you get the point.
PSS Comment does not provide a formula for all occasions.
UPD I forgot to subtract breaks, well, okay, let the working day be 8 hours, and I already subtracted it in the formula xD
