Software-intensive information systems deployment is an activity informally carried out in most companies. However, many of the problems that show up during the operation of the software systems are due to lack of accuracy in this process. This work intends to enhance the importance of adopting formal practices of information systems deployment. To this aim, an ASAP-based methodological guideline is adapted for the deployment of any type of software system, and the gap between this proposal and the ones used before is established. The results of this benchmarking show that the deployments have been made complying with only some of the methodological guideline activities. This work has made possible to convince the organization of the need to formally adopt this methodology, and can help other people in charge of ICTs in this job.
