What is the previous inspection?
Let's see, the prior inspection basically, is that check that the administration makes before any public contract is signed. It is not only to bother, huh, but to ensure that everything that was done before awarding that contract is aligned with the law, good management and internal norms that the entity on duty has. Imagine it is like when you check your exam before delivering it to the teacher: you do it so as not to put the leg.
This previous control works as a kind of anti-fraud radar and errors. If they catch something strange, they stop the process before something serious happens. It sounds super serious, and it is, because without that transparency and legality in public procurement would be a joke of bad taste.
Who takes care of this? Well, it depends: either does the entity's own internal control team itself, or the general intervention of the State, depending on the type of contract and the pasta that is at stake. These uncles have to review everything from the initial plan until they decide who gives the contract. Come on, they don't escape one.
Prior inspection is not just looking at papers without more. They check the documentation, make accounts to verify that the numbers fit, check that everything has been legally done and value whether the criteria for awarding the contract are correct. If they find something that does not fit, they can issue a repair report. That is basically a "huh, we don't continue until you fix this!" And the game is over until everything is in order.
For companies that want to catch a public contract, knowing how this roll works is vital. If they understand the process well they can avoid silly errors and have more options to take the contract. That is not a small thing, really.
And be careful, the previous inspection is not the only control. There are also controls after the contract is already being executed (concomitant control) and after everything is over (the subsequent control). Come on, that if you thought they only looked at you at the beginning, or coña.
In short, the previous inspection is key for things to be done well from the beginning in public procurement. If you are a company and you are interested in this world, you better soak up the subject so as not to stay out for a mistake. The difference between winning a contract or looking at you may be in those details.
