In order to carry out its projects, CISP makes use of human resources, selected on the basis of general criteria while keeping in mind the specific needs of each project.

In addition, CISP is able to commission service, work, and supply contracts to third parties, inviting companies to take part in tenders. These tenders are based on norms laid out in detailed notices and follow set criteria for transparency and maximum efficiency. In some cases tenders may be at a national, or even international level.
