As kids, we're told only people who go to college/university for politics/economics/law are qualifiable to make/run a country. As adults, we see no nation these "qualified" adults form actually work as a nation, with all manifesto-driven governments failing. Which to me validates the ambitions of all political theorist amateurs, especially as there are higher hopes now that anything an amateur might throw at the wall can stick. Here's my favorite from a friend.
My view (sorry for the British context and no cool name for it):
Have a King as head of state mainly in a similar role to now in the UK to be someone who can fire any ministers if needed.
No political parties. Simply have the public vote for a choice of 5 candidates for each cabinet minister post on 5 year terms.
These candidates must have at least 20 years experience of the field they wish to be minister of. For example, the choices for Health Minister would be between 5 people, who all have extensive experience in the field. So would hopefully understand what can and needs to be done. Rather than our current system of having a PPE graduate who has only ever worked in politics in charge of things they do not understand.
I also feel that removing political parties from the process would reduce some of the group-think that currently happens, as the public would be voting on the best policies for health, then for education etc. I think that would be an improvement over currently only having one vote and having to choose a party that ticks some but not all of your policy preferences.
