You don’t need another committee. You need at least one person who is in a position to act to say “What can I do this week that’s useful? Okay, let’s do that *now*”. Take the ‘free our bills’ thing as an example – they have some simple and clear issues with how the process works. If I was in a position where I was familiar with the systems and had access to the data (for example, the office that runs the parliament.uk website, but there are probably other places it could be done) and had no other demands on my time, then I would expect to have a prototype solution running by the end of the week, that dealt with most of their main objections (assuming a typical support workload, that would stretch out to 2-3 weeks). One month to run it past some sample users and stakeholders, get comments, fix issues they raise. Deployment time would depend on procedures, but should be no more than two months after that. The only thing that matters here is to get somebody to sit down and do it.
