According to one source, activity-based costing (ABC) "is an accounting methodology that assigns costs to activities rather than products or services."
ProSci, Loveland, Colo., posted an article, Activity Based Costing (ABC): What is it and how can reengineering teams use it?, at http://www.prosci.com/abc1.htm. This page offers a basic concept of ABC, but the site gets more commercial.
A better approach to the ABCs of ABC is found with Narcyz Roztocki, Ph.D., Professor of MIS, State University of New York at New Paltz School of Business. Her PowerPoint presentation is at www.pitt.edu/~roztocki/abc/abc.htm. Start with Activity-Based Costing (ABC) and Economic Value Added Internet Web site Guide. Below that you'll find plenty of links to ABC and Economic Value Added both in English and other languages.

One project you will find at http://www.gnu.org/projects/gnue/gnue.html is GNU Enterprise, software includes the ability to work with ABC.
Hearing is believing
Whereas most Web sites rely on countless pages of eyeball-numbing text to deliver content, the tag line for PC Radio is "Sound information on the Net!" The site, at http://www.pcradio.com/otr/strategy.html, offers audio recordings of interviews. You'll need RealAudio, software to access Easy as ABC at the bottom of the business strategy and management section.
Winsite Specialty Archives offers tmact200.zip, a package that captures ABC data by running a timer for whichever project or task the user selects and then stores the information in a database. Go to http://www.winsite.com/win95/access/page5.html and look near the bottom of the page.
Free ABC magazine
