This document presents the integration of design patterns and mobile applications, in the development of software management of plates (SIGEP) that allows to support in the solutions to problematics that they appear in the process of maintaining of plates copper cathodes of a Mining Company, in our case for Quebrada Blanca S.A. (CMQB S.A.). These problematics mainly are related to the little control over the tasks carried out in the maintaining to the cathodic plates, and the lack of information that leads to this practice, originates a deficient management and it does not allow to make opportune decisions referring to these elements, and therefore it does to project and to administer the life utility of the plates of cathodes, generating lifted costs associated to this process. As the process of maintaining a cathode plates constantly changing process, with respect to maintenance strategies in the system design SIGEP recognizing the flexibility and reuse in the design of system components, this achieved through design patterns used. The SIGEP implementation of the system and the incorporation of a mobile application, meant for CMQB S.A. increase control of the tasks carried out plates cathodes, allowing the company to detailed information on the maintenance of these elements, allowing among other things, identify cathode plates which are more expensive, and therefore knowing what must be replaced.
