I don't think this issue is specific to the IRS; it has much more to do with how the government is funded - via a series of Continuing Resolutions which make it really difficult to achieve any sort of long-term planning or projects. In the case of BSM funding, your source cites fluctuations are truly wild and were likely enacted on very short timeframes (i.e. months or weeks), which makes it incredibly difficult to hire and retain the expertise or make capital investments you need for success. The debacle around the IRS funding in the Inflation Reduction Act (the subject of the now-deleted parent comment I replied to) highlights these issues - a bunch of funding was allocated, some of it was later clawed back through a budget deal between the White House and Congressional Republicans, and a likely deal this January may continue to reallocate funding. I don't want to lay all the blame for all the IRS' ills at the feet of the state of government funding, but I certainly think it makes it really, really hard to get significant multiyear projects completed.
