Some companies have decided to no longer outsource such services, managing more closely and assertively with a focus on cost reduction and delivery quality. At this point, there are many difficulties in the implementation of a structured maintenance, which results in generating effort, costs and delay in servicing internal customers. Currently, there are very few specialized courses in facility management in Brazil. The search for skills has become increasingly important taking into account increasingly competitive markets. The main objective of this article is to show the importance and the challenges of a good facility management, the impact on the Core business of the company and the risks of an implementation without well-defined processes.展开更多
