What is a public service management contract?
Ok, let's take a more human turn to this:
A public service management contract, to see, is basically a treatment between a public entity - a City Council, a government, whatever - and a private company. The grace is that the company is responsible for a public service, but in the name of the government. Why do this? Because, supposedly, private companies are faster, more innovative, and all that always promise (sometimes they fulfill it, sometimes or coña).
Legally, these contracts are quite controlled. There are laws that mark how the entire process should be (in Plan, the Law of Public Sector and such), so that no one passes from ready and for the competition to be real. That is, nothing to give the contract to your cousin: everyone has to have the same possibilities and the contest has to be clean ... well, in theory.
If you are a company and want to get in this roll, you have to know that it is not turkey mucus. Not only do you have to do things well and how they ask you in the contract, but you have to comply with a lot of standards: from equal employment to environmental and security issues. Come on, you can't go for free.
And be careful, these contracts are not like the typical agreements between private companies. They usually last for years and are watching you all the time. If you, prepare: sanctions, they throw you, and forget that they call you again for something public. There are no second opportunities here.
Of course, if you do well, the reward can be huge. These contracts are usually worth a good pasta and give you a stability that few things in the business world will give you. In addition, it gives good image: you can go there saying that you contribute to society and all that.
Summarizing: a public service management contract is that agreement where a company is responsible for a public service commissioned by an administration. It is a good opportunity, but also a brown if you don't know where you get. If you want to play in this field, you better be clear about the regulation and be willing to commit yourself in the long term. And, above all, not shit it.
