As for the future state planning portion of a BA, the incorporation of technology to systemize, organize, and make information accessible and available will really help with collaboration and unifying the organization. Future planning allows the opportunity to critically analyze what is already established and identify how it could be improved to further build on effectiveness and efficiency. However, there are gaps between the current and future state because of a number of reasons which usually entail the lack of resources. Furthermore, only a small component could be focused on at a time. A full fledge switch over or removal of a service will have a damaging affect on the rest of the organization.
Hence, the need to understand both current and future states begins a platform for the rest of the EA. The details creates clarity that could be readily communicated and fulfill the next steps in formulating an organization that could adopt changes fluidly. The BA altogether allows a focused area to start planning and visualizing a complete image of how the organization's mission statement will be truly defined.
