Large companies often decide to use enterprise-wide tools and technologies, with the idea that this will simplify things. For instance, there might be a support department that provides first-level support for the tools and also functions as the tool provider’s only interface. Furthermore, this department could also help establish the knowledge required to use the tool or technology by providing coaches or training courses. Another important reason is that the tools will be much cheaper if the enterprise orders hundreds of them rather than each project team ordering just a few copies. It also eliminates the burden on each project team to evaluate different kinds of tools and technologies, which could be really time-consuming.
