Open source is a large ecosystem, with large and small systems integrators who are delivering software and services in a new way. Some agencies may have relationships with certain preferred partners, and that's terrific. Just make sure the partners have the right level of open-source experience.

Any good CIO will want to make sure the software they're using is well supported, whether it's open-source or commercial code.
