Our sources to date: organizations that have presented at Society conferences, use documented in books, dissertations, articles, in newspapers, magazine or other media; also organizations that have given permission to their work-levels-based consultants to place their logos on the consultant's web page - under clients. We hope to identify another 100 to use in preparation for the 2017 conference.
If you are a company manager who can place your company on public record, please help.
Or if you are a consultant already with permission to place your client's logo on your page or otherwise you know them to be on public record please provide us with the organization name and country of the project. Or let us know who to write to for permission.
