how the analysis can collect the information

how the analysis can collect information

 Systems analysis is the study of sets of interacting entities, including computer systems analysis. This field is closely related to requirements analysis or operations research. It is also "an explicit formal inquiry carried out to help someone (referred to as the decision maker) identify a better course of action and make a better decision than he might otherwise have made.
its is the first stage on system analyzing where the analysis will analyse the existing system and see how the work get done and how the company make use of its programs and software
