## 7 Conclusions and Further Work  
This article presents a novel MCC-based mobile platform to support the knowledge management process of SMEs in the Chilean construction industry. The approach applied allowed us to encapsulate the complex design decisions and trade-offs involved in the architecture of a mobile application with augmented capabilities via cloud backend services destined for improving knowledge management in SMEs construction companies. The KM platform was built with different cloud services provided by Microsoft Azure. The platform has been considered by users as a useful tool with great potential to improve the performance of the knowledge management process, as it provides systematization of a process that has not yet been formalized in Chilean SMEs. To develop the platform, different research cycles were performed divided into three distinct phases (Build-Measure and Learn) according to the lean development methodology. This research methodology allows for the development of a platform that focuses on the specific needs and requirements of SMEs in Chilean construction companies, recognizing the particularities of their work and their cultural characteristics, as they are relevant factors to take into account in order to have a successful system. In this way, this research addresses a gap as similar systems may be MCC-based, may focus on KM process, may be designed for construction companies and/or SME's, but do not simultaneously have these four qualities. According to the positive result of the evaluations, this research concludes that the proposed platform is already responding to the needs of this sector using the trending paradigm of MCC, thus helping to close the research gap identified at the beginning of this article. This was achieved by constantly testing and improving the hypothesis of the system and the research through research cycles. Regarding the implementation of this MCC-based platform, this study is able to conclude that using a cloud backend combined with mobile applications is a way of enhancing SMEs KM by providing this process with powerful data storage and data processing capabilities at an acceptable level of cost and risk. Shifting large volumes of data to the cloud provides a flexible and scalable platform for developing a variety of scientific data-processing tasks. MCC is then, a very attractive option for KM in construction SMEs from multiple perspectives. For instance, the mobility introduced by the mobile application helps with the reutilization of past experiences on-site. Moreover, it is financially attractive because these services may be hired at prices that fit the needs and size of the company. Besides this, CC capabilities supporting the backend functionality are expected to be better than an in-house solution, as they are provided by specialized vendors instead of being deployed by IT departments that, most likely, are not experts in the subject. In terms of the mobile application itself, the use of a cross-platform framework in the construction industry domain is feasible. A cross-platform framework meets the requirements of mobile applications with non-complex UIs and accelerates the development of applications targeting the most popular mobile markets. Cross-platform development also makes it possible to offer a similar user experience for most mobile users and helps to maintain the consistency of the information and business logic, as most of the code is reused on all platforms. In addition, if the framework allows the code to be deployed in native applications (as Xamarin.Forms does), performance is not hindered. These conclusions are supported by the test results of the third cycle. In terms of offline usage, systems targeting the construction sector must have an offline mode that allows access to the most recent copies of any important information available and synchronization with the centralized servers (e.g., cloud backend) once connection is restored because maintaining a stable Internet connection is almost impossible on construction sites.
