I’ve faced this at multiple jobs at orgs of different size. My solution was to always have more than one thing available to work on so when one task bogs down in the mud due to organizational processes, I can go work on something else until the blocked task makes progress. If you don’t have alternative things to do while things block, you might see about getting other things to do. Or, adapt your work style to minimize the number of times you run into these obstacles. The people I see get most frustrated are those that don’t adapt to the system and get frustrated when it doesn’t work the way they want it to. Adapting may be annoying and may break some comfortable habits, but in the long run I find it to be the route of least angst.
