The gold standard for estimating time in software is as follows: Make your best estimate. Multiply the number portion of the estimate by 3 Change the time unit upwards to the next unit. For example. I estimate 2 days 2 X 3 = 6 Days changes to weeks Realistic estimate 6 weeks. Another example. I estimate 1 month 1 X 3 = 3 Months changes to years Realistic estimate = 3 years. John W.

Then double it. Add a few hours of hair pulling and teeth grinding. Then, for every form involved, add 15 minutes if their bound, an hour if their unbound. Add 45 minutes for every Global variable that you plan on using. Once all that is done, triple your time. Look at your projected start date, and multiply the current 'time projection' by 100% + the current phase of the moon divided by the average rain fall for that month over the past ten yeats. After all that, a one more day for good luck, and you should be as close as you can get then.

How do you determine the amount of time required to build an application? I need to do it for an internal project, but I have NO idea how to estimate the time. I already know what the application needs to do and produce, but I haven't got the foggiest idea how to estimate time. I will be the only one that will be developing it, so I don't have to worry about other people, just me. Thanks for any hints, tips or ideas. -- Bryan Carbonnell - carbonnb at sympatico.ca Unfortunately common sense isn't so common! -- _______________________________________________ AccessD mailing list AccessD at databaseadvisors.com http://databaseadvisors.com/mailman/listinfo/accessd Website: http://www.databaseadvisors.com -- _______________________________________________ AccessD mailing list AccessD at databaseadvisors.com http://databaseadvisors.com/mailman/listinfo/accessd Website: http://www.databaseadvisors.com
