Open Data’s consulting philosophy is nicely summed up by Marvin Bower, one of McKinsey & Company’s founders. Bower led his firm using three rules: (1) put the interests of the client ahead of revenues; (2) tell the truth and don’t be afraid to challenge a client’s opinion; and (3) only agree to perform work that is necessary and something [you] can do well. You can find more information about Marvin Bower and his business philosophy in this biography.

Open Data’s outsourced services employs open source software whenever it can for two important reasons: First, some of the highest quality software is open source. Second, by using open source software for its outsourced services, Open Data provides better value for its clients. Open Data also develops open source software for data mining and analytics, which it uses for the majority of its projects. For example, a typical Open Data outsourced analytic service is built over Linux, R, Augustus, Python, MySQL, and PHP .

Open Data also develops cloud-based analytic services using Hadoop and Sector/Sphere.

In addition, Open Data incorporates open source software and methodologies developed by the National Center for Data Mining at the University of Illinois at Chicago, the Data Mining Group, and the Open Cloud Consortium for particular specialized solutions.

Open Data is located in River Forest, Illinois, which is about 10 miles west of downtown Chicago. Directions can be found here.
