Open Source vs. Standard Software - What is the difference?
Standard Software is sold and supported commercially
However, Open Source Software can be sold and/or supported commercially, too.
Perhaps, the term Proprietary Software is more correct
Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 2009
Definitions of Open Source Software (I)
Open source is an approach to the design, development, and distribution of software, offering practical accessibility to a software's source code.

Definitions of Open Source Software (II)
Some consider Open Source as one of various possible design approaches, while others consider it a critical strategic element of their operations. [1]

What is the difference? (I)
Usually the question of Open Source vs. Standard Software is framed as Linux vs. Microsoft Innovation vs. Security etc.

What is the difference? (II)
However, this is just a simplification from a Marketing Point of view, because …

Free & Open Source Initiatives …
… have been there for ages and… have produced various licensing
schemes… are responsible for some of the
most radical ICT innovations that man kind has seen so far!

Open Source History (I)
Very similar to open standards, researchers with access to the Advanced Research Projects Agency Network (ARPANET) used a process called Request for Comments to develop telecommunication network protocols.

Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 200912
Open Source History (II)
Characterized by contemporary open source work, this 1960s' collaborative process led to the birth of the Internet in 1969. [1]
[1] http://en.wikipedia.org/wiki/Open_source
Open Source History (III)
There are earlier instances of open source and free software such as IBM's source releases of its operating systems and other programs in the 1950s, 60s, and the SHARE user group that was formed to facilitate the exchange of software. [2][3]

Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 200915
Open Source History (V)
The term Open Source gained popularity with the rise of the Internet, which provided access to diverse production models, communication paths, and, last but not least interactive communities.

Open Source History (VI)
The decision by some people in the free software movement to use the label “open source” came out of a strategy session[4]
held at Palo Alto, California, in reaction to Netscape's January 1998 announcement of a source code release for Navigator.

Open Source History (VII)
They used the opportunity before the release of Navigator's source code to free themselves of the ideological and confrontational connotations of the term free software. Netscape licensed and released its code as open source under the Netscape Public License and subsequently under the Mozilla Public License.[5]

Potential Benefits of Standard Software
Potential Benefits of deploying to standard software in an application solution: Understand and comply with the
business & technological models of commercial software engineering in a professional environment
Support of standard software / solutions, including services
Compliance with industrial standardsOpen Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 2009
21
Potential Benefits of Open Source Software (I)
Availability of source code Source code to understand and learn
from Do not have to re-invent the wheel Free as in “freedom” And sometimes:
free as in “gratis”
Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 2009
22
Potential Benefits of Open Source Software (II)
Does not depend on vendor Can choose additional support Can fix bugs and adapt to change in
requirements as well as technology
Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 2009
23
Potential Disadvantages and Riscs of Standard Software (I)
Dependent upon a single vendor What if …
… the vendor disappears from the market? … the vendor charges too much?… bug fixing and enhancements not sufficient? etc.
Monopoly?Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 2009
24
Potential Disadvantages and Riscs of Standard Software (II)
Too much Intellectual Property can be bad for innovation …
Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 2009
25
Potential Disadvantages and Riscs of Open Source SW (I)
If source code is not looked at, there is no need to have Open Source SW
There are also bad codes, unqualified persons which use it, etc.
Open Source vs. Commercial Software Impacts on Library Infrastructures – Amsterdam, 5 th of October 2009
26
Potential Disadvantages and Riscs of Open Source SW (II)
Software quality assurance process is widely not transparent
etc.

IT has become a Commodity and is therefore expected to support almost any kind of Enterprize Application like a Service-Center
Significant Cost Pressure requires new
positioning: Which are Core Competences? Which are Competences that can be supported
economically?

Make or Buy? (IV)Open Source – an Alternative for Libraries?Potential Advantages
of building on Open Source
Software is „free of cost“ Sourcecode is freely
available High Flexibility Own Requirements can be
mapped very detailled to Features
Open Standards Independency of Providers
Potential Disadvantages of building Open Source
Full Deployment Risk W.r.t. Completeness and Robustness of
Functional Features Development-Know How is bound to human
resoures
Total Cost of Ownership High Follow-up Cost for Maintenance of
Application Features and Interfaces Need for own Support Infrastructure Höhere Schulungskosten
No secured follow-up development strategy
Need for own Development Resources and Strategy
„Time to Market“ pressure

Make or Buy? (V) There is now Standard Answer ...
... but a set of questions to be systematically analysed and answered as a decision support:
Is IT application developement a Core Competence of the Library?
Does the Library win a Strategic Advantage by means of own IT Developements?
How big is the Functional Delta to features of Standard Software?
Economic Analysis? Total Cost of Ownership (TCO)?
Time to Market – How long until Production? How are the chances for follow-up funding of
necessary further Evolution of the Solution? Is there a Funding Basis/Community?
