# Thread: Golden Rule No 2.5

1. ## Golden Rule No 2.5

One of my golden rules in assessing how much time it will take to do a job :~

a. Make a reasonable prediction of the time you think it will take
b. multiply that time by a factor of 2.5

c. Take another look at the job in hand & ask yourself if 2.5 will be enough (very pertinent if you are trying something new / experimental / untried / for the first time )

d. Build the result & cost into a fee proposal.

I can accept no responsibility for any inaccuracies you may experience but I find as a general rule it is far better than "a." on its own

For software development I've found a factor of 3 is about right, though it varies based on the programmer.

3. ## Re: Golden Rule No 2.5

A firm I used to work for used a factor of 3.5 as their "multiplier".

The value fluctuates between Euler number / base of natural logarithms (2.71828182846...) and Pi / π (3.14159 26535 89793)

Yeah .... course .... just as you'd expect.... I knew that

I've usually used a factor of 3 which is about right, but prefer "Leonid's" answer as it appeals to my warped geeki-ness...

7. ## Re: Golden Rule No 2.5

But can you quote pi to 15 decimal places, from memory, as Leonid can.....

In school we always used 2.58... Close enough I guess.
