[text] If a software developer takes 365 days to write a piece of software how many developers will it take to write that piece of software in 1 day Assuming that the software developer takes 365 days to write a piece of software working alone we can estimate the number of developers required to complete the same software in one day. Lets assume that the developer works fulltime dedicating 8 hours per day to software development. Furthermore well consider that they spend the entire 8 hours each day actively coding without any interruptions or breaks. 365 days 8 hoursday 2920 total hours of work If we want to complete the same amount of work in 1 day we need to divide the total number of hours by the number of hours available in a single day 2920 total hours 24 hours 12167 developers Since we cannot have a fraction of a developer we can round up the number to 122 developers. Therefore it would take approximately 122 developers working together for 8 hours to complete the piece of software in one day.
