Tanzania is an example that comes to mind. I can't remember all the details but in these days vague impressions seem to have value. Tanzania like so many other countries developed Poverty Reduction Strategies (PRS)at the beginning of the century. This was under the initiative of debt reduction to promote poverty reduction. They first had to do Interim Poverty Reduction Strategies , because the IMF wanted to show "rapid results". These were supposed to be 'participatory'. (But in an Overseas Development Institute review with the donor support there was a brilliant quote of an attendee at a PRS conference to present the draft IPRS standing up to say "I have been participated".) The implicit idea was that if a Strategy was participatory then it was "legitimate" until the next one came along. No-one considered the political cycle and the relative legitimacy of a new government's programme and a prior determined DP supported PRS. Perhaps this was because many of the PRS countries at the time were not multi-party (bi-party) democracies, with the frequent alternation of governments that such places enjoy.
Tanzania's Government has been of the same partly for a long, long time, but still its policies change and evolve. There the medium term planning and budget processes have to take account of the National Strategy (or whatever it is called) and also the Government's programme. The idea is that the one succeeds the other and that "news" and "new policies" should be taken into account.
I remember Gord Evans and I chuckling over the irony of DPs enthusiastically promoting democracy but lamenting the inconvenience of having to adapt their processes and "assistance strategies" to inconveniently timed expressions of the will of the people.
For me it is just the nature of the will of the voters. As Aristotle (living in a different time and place, e.g., UK 2016 ) might say "all adults can vote, some adults are idiots, some idiots can vote".
