This document aims to highlight the details of the development of the project that our company (the company where I am working) will do, as well as its validations from the client, HIDRO, in order to install and adapt CRM 365 to this client. My motivation to do this projectstarted because of my job. I am working in a software consulting company from Lleida which aims to sell Microsoft Products and install them on any company. These software are mostly Enterprise Resource Planning (ERP) and Client Relationship Management (CRM). I am in the CRM department and I am member of the team who will carry on the CRM development on a specific company (named HIDRO),so I thought it would be a great idea make a final project about it. The company where we implement the software, called HIDRO, is a group of companies that operate in different phases of electricity generation. We will introduce a proposal to present the effective implementation of a modern and powerful solution, which include commercial management and marketing. Although the initial scope is limited to commercial and marketing management, our company, as a global partner of Microsoft cloud services, will support HIDRO in all areas.
