Professor at FGV's Brazilian School of Public and Business Administration (EBAPE), Gregory Michener, was the interviewee in the latest edition of the series OpenGov Conversations, a section on Sunlight Foundation's website, dedicated to international researchers and professionals specialized in transparent public accounting. In the interview, Gregory spoke about the preconditions for governments to achieve effective transparency. In order to make the transparency policy effective, people need to, first of all, be transparent - in the best possible way, a transparency of high quality. Transparency needs visibility (comprehensiveness, accessibility) and conclusion by inference (the ability to draw precise conclusions) to exist, he said in an interview. The Sunlight Foundation is located in Washington, in the United States, and is considered the largest and most important Non-Governmental Organization (NGO) working in transparency policies in the country. Please click here to read the article, in English.
