Provide a one stop shopping information portal to the public that lists data and metrics related to the Top 3 Strategic Goals for each and every DHS Component. Quarterly would be reasonable I suppose. If a component's goal was 10 annually, and 1st qrtr was 3, second qrtr was still 3, that component would not be pleased to post that performance. That's accountability. The goals should be of public interest. Sharing meaningless data for the sake of sharing seems pointless and wasteful.
The public wants to know how DHS is performing and what are the goals. For Coast Guard, how many lives were saved this year (= CG saves lives). For TSA, how many security screenings nabbed bad guys (= TSA screens bad guys). etc., ect.
Allow the public to post moderated comments related to the component performance goals. Feedback must be two-way to be useful/effective. I'm not sure the average American even knows how many components make up DHS and what they are all tasked to do. How can they even begin to think about accountability?
A single performance portal (name it something better than that) would better frame DHS for the public. No current websites or blogs represent the Department in a simplistic way. Could even have all of the seals from each component in that one website. I've never seen that.
