Document Summary

System: collection of related programs or applications. These programs work together in an organized way. They communicate through files, databases, and networks. Systems can also have: non-computerized components (ex. people or other types of machines, processes that are performed outside of a computer system. Systems analysis and design involves: determining the system requirements, designing the system and its components, managing its implementation, managing its deployment. Need to find most efficient way to produce a product (involved both people and machines) Systems analysis can trace its roots back at least one hundred years to the assembly line. Moved into the office environment ~1930s - used to automate office processes. Early systems analysts were often called efficiency experts - spent a lot of time measuring time to perform simple operations. Primary goal of early systems analysis: converting manual processes to computer, computerization of information based systems. Before converting a manual system to a computer based system, the existing system was analyzed.
