3. “The GPL effectively prevents profit-
making firms from using any of the
code since all derivative products must also be
distributed under the GPL license” (Evans, D.,
in “Government policy toward open source
software”, R.W.Hahn, editor, AEI-Brookings
JCRS)
SfsConf 2012
4. “[..] the aim of free software is not to enable a
healthy business on software but rather to
make it even impossible to make any
income on software as a commercial
produc t.” (Thomas Lutz, Microsoft
representative at Tunis WSIS, 2005)
SfsConf 2012
5. “Open-source software is deliberately
developed outside of market mechanisms... the
nonmarket coordination mechanism fails to
contribute to the creation of value in
development, as opposed to the commercial
software market. [It] does not generate profit,
income, jobs or taxes … In the end, the
developed software cannot be used to
generate profit.” (Kooths S., Lagenfurth M.
“Open Source-Software: An Economic
Assessment” University of Muenster, Muenster
Institute for Computational Economics)

6. “[Open Source] ... suppresses quality
competition between OS firms and restricts
their output much as an agreement to suppress
competition on quality would. .. We find that
the first-best solution in our model is to tax
OS firms and grant tax breaks to
[proprietar y sw] firms .” (Engelhardt,
Maurer, 2010 Goldman School of Public
Policy)

possible because passengers, unable to
breathe, would die of asphyxia.” Dr. Dionysus
Lardner (1793-1859), Professor of Natural
Philosophy and Astronomy at University
College, London.
“Heavier-than-air flying machines are
impossible.” Lord Kelvin (1824-1907), ca.
1895, British mathematician and physicist

8. Measuring value is complex. A bad way of
doing it: “...First we listed the major open
source products. Then we looked at the
commercial equivalents. Next we looked at the
average cost of both the open source products
and the commercial products, giving us a net
commercial cost. We then multiplied the net
cost of the commercial product by our open
source shipping estimates.” (Jim Johnson,
Standish group)
SfsConf 2012
9. Some groups measured the total revenues of
FLOSS firms; so Pierre Audoin Consultants
found a total market of 8B€ in 2008.
Unfortunately, HP alone made 2.5B$ in Linux-
related consulting in 2003, while IBM made
4.5B$ in OSS-related revenues in 2005 (as an
example, the OSS PBX market alone is 1.2B$
alone.)
In fact, the majority of FLOSS-related
revenues are not made by FLOSS companies at
all.
And the software market is not that easy to
define as well.
SfsConf 2012
12. This provides us with an overall IT spending estimate
for Europe: 492B€
approximately 24% is hardware

15. How much FLOSS is inside the average
codebase?
● On average, 30% of implemented
functionalities is based on reused OSS code
(Sojer M., Henkel J. “Code reuse in Open
Source Software Development”)
● Gartner reported that among the surveyed
customers, 26% of the code deployed was
Open Source
● The Koders survey in 2010 found that 44% of
all code was Open Source
SfsConf 2012
16. ● Black Duck analysis of large code projects
(avg. 700MB of code): 22% is FLOSS, up to
80% of new development is avoided through
FLOSS
● “sampling continues to find that between 30%
and 70% of code submitted is .. in the form of
OSS components and commercial libraries”
(Veracode, “State of Software Security Report
volume 3”, 2011)
● Sampling shows that FLOSS use increases
with time → average usage for last 5 years:
35%

20. “Figures suppor t the idea that FOSS
solu tions are more innovative than
proprietar y ones: indeed, in all the three
dimensions, experts’ evaluations are higher for
FOSS than for proprietary software. … FOSS
software not only show different levels of
innovativity, but, as far as, new to the world
products are concerned, they are also shaped
by different innovation processes: radical
innovation in the FOSS vs. incremental
innovation in proprietary field.” (Rossi,
Lorenzi, “Innovativeness of Free/Open Source
solutions”)
SfsConf 2012
21. "The growing rate, or the number of functions
added, was greater in the open source projects
than in the closed source projects. This
indicates that the OSS approach may be able
to provide more features over time than by
using the closed source approach. (Paulson,
Succi, Eberlein “An Empirical Study of Open
Source and Closed Source Software
Products”)
SfsConf 2012
22. "Findings indicate that community Open Source
applications show a slower growth of
maintenance effort over time.” (Capra,
Francalanci, Merlo “The Economics of

implying constant incremental effort, might be

24. Project failure data:
● Jones :“the cancellation rate for applications
in the 10,000 function point size range is
about 31%. The average cost for these
cancelled projects is about $35,000,000”
● Standish group, 2009: 24% of projects are
canceled before deployment
● Sauer & Cuthbertson, in an Oxford university
survey of 2003: 10%
● Dynamic Markets Limited: 25%+ of all
software and services projects are canceled
before completion

SfsConf 2012
26. By reducing effort, staffing and duration the
35% code reuse introduces a reduction on
these parameters of 10% → a reduction in the
failure rate of 2% → 4.9B€/year
SfsConf 2012
27. “While IBM initially contributed software that was
valued at 40M$, external contributors to the project
created software representing a value of roughly
1.7B$ over the examined period.” (Spaeth,
Stuermer, von Krogh “Enabling knowledge creation
through outsiders: towards a push model of open
innovation”)
SfsConf 2012
28. ● OSS maintenance effort is substantially lower
than the average (Capra E., Francalanci C.,
Merlo F., “The Economics of Community Open
Source Software Projects: An Empirical
Analysis of Maintenance Effort”)
● Using a model by Jones and Bonsignour,
traditional code does have a cost of 2000$ per
function point, while code shared or developed
using best practices costs 1200$ per FP
● the shared code in a reused OSS project
introduces an additional reduction in
maintenance and dev. effort of 14%

29. 14% reduction in maintenance and
development costs → 34B€/year

35. ● “The principal results from this econometric
analysis are: 1) the measured output
contribution of computerization in the short-
run are approximately equal to computer
capital costs, 2) the measured long-run
contributions of computerization are
significantly above computer capital costs (a
factor of five or more in point estimates), and
3) that the estimated contributions steadily
increase as we move from short to long
differences. (“Computing productivity: firm-level
evidence”, Erik Brynjolfsson, Lorin M. Hitt; Review of

42. ● Does the increase in efficiency reduces local
revenues for incumbents?
● For commercial products (that is, proprietary
products that embed OSS): the producer
reduces its production costs with no other
impact on the business itself, so it can either
increase its margins or pass some of the
savings to the customer.
● For internally developed products, the savings
are direct, with no other effects on the external
market
● OSS reinvestment are mainly local

spending goes outside of Europe-and reduces

● More difficult to assess – huge variability in
outcomes
● In desktops, with successful migrations, TCO
reduction ranges from 10% to 25% (typical)
up to 50% (for high-uniformity environments)
● Movement towards web-apps is changing
substantially the economics of moving from/to
a different platform, reducing the transition
cost → requires a move away from “pure
substitution” to “reengineering for the future”

48. ● Non-code contributions: value deriving from
anything that is not directly compilable
● “[non-code] outside contributions are
signicant. Open Cascade estimates that they
represent about 20 % of the value of the
software. Matra Datavision had to inject
approximately 2M€ per year to continue to
develop its tools. In 2000, the company limited
the costs to 1.2 million.” (Jullien, Clement-
Fontaine, Dalle “New Economic Models, New
Software Industry Economy”)

52. “A study carried out between January and
June 2010 shows that despite the desired
affirmative action for open source products, in
almos t half (47.5%) of the tenders
there is s till a preference for closed
source vendors or products. This
preference inevitably results in not giving
vendors of FLOSS a fair chance to win the bid.
(Mathieu Paapst, Center for Law and IT,
University of Groningen, the Netherlands)

53. ● The vendor must employ MS certified
employees.
● Asking for an operating system to be used
together with the Microsoft Campus
Agreement.
● If your bid is open source you should give extra
guarantees concerning the stability of the open
source community.
● Not allowing “zero-price” licenses.
● Demanding that offered applications must be
certified by Microsoft, are Oracle 10 compliant
and using the official Microsoft style guide as
much as possible.
