Congress keeps handing agencies new tools: prize competitions, "other transaction" agreements that sit outside the procurement rulebook, direct hiring. This tracks when each agency got each tool, when it first used it, and how use grew after that.
How many agencies held the power each year, and how many had used it at least once. The space between the lines is agencies sitting on a power they had never used.
Each agency's cumulative use, lined up by years since it got the power. Lines that stay low for years and then climb are powers that sat in the drawer before taking off. Pick an agency to highlight it.
Every authority in the dataset with a known grant date, the first use we could document, and the year use first reached half of its eventual peak. Click a column to sort. The family buttons above filter this table; choose All to see everything.
