Open Source Software: Case Studies Examining its Use - The Dravis Group (April 2003)

A Business Case Study of Open Source Software - MITRE (by Carolyn A. Kenwood, July 2001)


"In the Executive Summary, the paper explains open source, describes its significance, compares open source to traditional commercial off-the-shelf (COTS) products, presents the military business case, shows the applicability of Linux to the military business case, analyzes the use of Linux, discusses anomalies, and provides considerations for military Program Managers. The paper also provides a history of Unix and Linux, presents a business case model, and analyzes the commercial business case of Linux." More about MITRE at http://www.mitre.org/about/index.html .

Guitar maker plays a Linux tune - Infoworld (by Matt Berger, November 27, 2002)


An informal look at the migration to Linux by Ernie Ball Inc., a company of about 80 employees. After a clash with the BSA, Ernie Ball was motivated to switch. "I think that we were so driven to find a solution that the worst reality to us would have been to give up and go back to the people up in Redmond," said Sterling Ball, President and CEO of Ernie Ball. The Ernie Ball story is entertaining but also far from typical, as most migrations are done gradually.

European Union: European Commision The Interchange of Data between Administrations Open Source Migration Guidelines

Informal Open Source migration stories involving:

Migration from Windows to Linux saves thousands - IT Manager's Journal (by Ryan Benner, January 14, 2004)


"I advise all the administrators, CFOs, CEOs, and IT personnel who have not taken a look at Linux to start to look at the software as a viable solution to price-gouging of other systems. You can cut administrative costs, licensing costs, and hardware costs by half; you can increase security and up time; and you won't have to make major migrations every few years in order to maintain your support options."

Linux Going Mainstream - Linux leads open-source move into running key business processes and systems (by Larry Greenemeier, May 24, 2004)


"With the likes of UPS and Boeing getting comfortable with the operating system running critical business systems, the momentum behind Linux will continue to build. That means Linux and open source are set to increase their impact on the business world."

This article includes information from a survey, possibly this one: http://www.informationweek.com/reports/showReport.jhtml?articleID=20900120

Automaker Audi Implements Linux - Network Computing (by David Joachim, February 5, 2004)


"In fact, the (Audi) VR unit's move to Linux was driven largely by Magma GmbH, which supplies Audi with simulation software to plan the manufacturing process for new car designs before prototypes are available. Magma had never optimized its simulation tool for HP-UX or other variants of Unix, but had done so for Linux systems from Linux Networx and Siemens Fujitsu."

"For now, the lack of ISV (independent software vendor) support for most Linux variants makes it difficult for enterprises to commit to Linux for everyday applications. The next battleground for the Linux vendors may be for the hearts and minds of ISVs, as the vendors try to extend their footprints beyond single-purpose server installations."
