Marketing material: Open source cost estimators

[fkromer]

For marketing purposes it could be valuable to use cost estimators like e.g. the one from www.openhub.net (here for OpenMS) to showcase how much open source software would cost companies if they would develop them in-house :smile:

Interesting idea! This shows very directly how much companies profit from open-source. Of course these calculators are always a bit inaccurate, but it gives an idea. This would need to be done in a case-study for each company, right?

This does relate to Issue #9 in some way. When you are able to estimate the costs of a project, (based on multiple historical data) you could use the simulator to tune the OpenSelery config in this way that I will payout this amount over time.

@cornerman It's about to make SW development cost transparent to non-software people, in most cases management people. The only thing which is relevant for them is numbers. Then let's give them numbers for well known projects like e.g. pandas:

Average Salary (per year): $ 55000.00
Codebase Size: 326,328 lines
Estimated Effort: 86 person-years
Estimated Cost: $ 4,739,115 *
*Using the Basic COCOMO Model

Here's another well-known project: ROS2

Average Salary (per year): $ 55000.00
Codebase Size: 195,549 lines
Estimated Effort: 50 person-years
Estimated Cost:  $ 2,754,851 *
*Using the Basic COCOMO Model

That is also related to the issue #37. We could actually create a badge that shows the value of the project. This could also been used as a weight for funding distribution like the COCOMO or git-hours
