what is the purpose of system vision document
Vision document A Vision Document is a document that describes a compelling idea or values or future state for a particular organization, product or service. It defines the stakeholders view of the product/service to be developed, specified in terms of the stakeholders key needs and features. Containing an outline of the envisioned core requirements, it provides the contractual basis for the more detailed technical requirements.

Business analyst The role of a systems analyst can also be defined as a bridge between the business problems and the technology solutions. Here business problems can be anything about business systems, for example the model, process, or method. The technology solutions can be the use of technology architecture, tools, or software application. System analysts are required to analyze, transform and ultimately resolve the business problems with the help of technology.
