Hi Jan,
We actually did the math last year for ACEU 2014, I'll try to find it
for you.
But in short, take the LF number, multiply it by 1.25 and you sort of
get to the figures we were discussing back then.
This is highly subjective and not in any way an _actual_ science
(neither are the LF numbers, they're all just big guesses), but it's fun
do try out the math :)
We have around 140-150 million lines of code at the moment, which by
using our own model would take around 38k person-years to do (LF has
used some math that makes coding take even longer - by their standards,
it would take 50k person-years to write our code). We had a very
conservative cost estimation at $2B back then. By LF standards, that
figure would be $6.1B.
With regards,
Daniel.

Hi.
This report is real interesting reading, it could be real cool to do the
same math for ASF.
Is anybody interested in forming a small work team (a LABS project), and
try to do the calculation for ASF ?

NEW Report: Estimating the Total Development Costs of Collaborative Projects
<http://go.linuxfoundation.org/e/6342/ndation-collaborative-projects/2v9lw6/660023375>
The
Linux Foundation today is releasing its first-ever report that attempts to
measure the collective value of development costs in its Collaborative
Projects. The report is titled “*A $5 Billion Value: Estimating the Total
Development Cost of Linux Foundation’s Collaborative Projects
<http://go.linuxfoundation.org/e/6342/ndation-collaborative-projects/2v9lw6/660023375>.*
”
Linux Foundation Collaborative Projects are independently funded software
projects that harness the power of collaborative development to fuel
innovation across industries and ecosystems. More than 500 companies and
thousands of developers from around the world contribute to these open
source software projects that are changing the world in which we live.
*Top-level findings from the report include:*
- The total *lines of source code* present today in Linux Foundation’s
Collaborative Projects are *115,013,302*.
- The *estimated, total amount of effort* required to retrace the steps
of *collaborative development* for these projects is *41,192.25 person
years*.
- In other words, it would take *1,356 developers 30 years* to recreate
the code bases present in Linux Foundation’s current Collaborative Projects
listed above. The total economic value of this work is estimated to
be over *5
billion dollars*

We believe that when people have the tools and trust to collaborate on a
massive scale, nearly any problem can be solved. In fact, the most complex
technology challenges of our day are being solved through collaboration and
what we call Distributed Genius
<http://go.linuxfoundation.org/e/6342/-player-embedded-v-SqXUu-EsAiE/2v9lvn/660023375>.
Distributed Genius is when thousands of people from every corner of the
world bring their genius and their unique experience to bear.
