Unlike the Parliamentary system, the concept of 'question hour' or 'question time' doesn't really exist in the American legislature. Here's an interesting report done by the Congressional Research Service on the possibility of a question time in the US. From our point of view, the report is interesting because it reviews the existing provisions for a Parliamentary Question Time in different countries (India isn't mentioned), and considers the pros and cons of such a system. The report concludes: "Whether the question period would be successful in a system of separated powers depends in large part on the attitude of its participants and on the format the question period ultimately assumes. The question period has the potential of involving more rank-and-file Members in the policy-making process, and improving the means of communication between executive departments and the Congress. It also could harden relations between the Congress and the Executive, and might increase the level of partisan controversy in Congress." There's even an online petition among a few american bloggers to push for a question time in the US. Read about it here. In this country of course, parliamentary questions are an established feature of the work of Parliament. Parliamentary questions cover a huge range of topics and can be an mine of information and data about government policy. The Lok Sabha and Rajya Sabha sites put the complete text of all parliamentary questions (and the responses to them) online.
In the aftermath of the 2G scam, there has been a great deal of discussion on how Parliamentary Committees can be used for scrutinising the functioning of the government. Committee Reports are generally put in the public domain, but how transparent are the internal workings of the Committees themselves? As one measure of transparency, minutes of Parliamentary Committee meetings are included in Committee reports. The meetings themselves, however, are held behind closed doors. A number of other democracies allow in-person public viewing of some (if not all) Committee meetings. Several of these offer live webcasts of meetings as well. See options in Canada, New Zealand, Scotland, and the United Kingdom.
