Through a combination of interviewing employees, circulating questionnaires, observations and existing documentation, the analyst comes to full understanding of the system as it is at the start of the project. This serves many purposes. BUSINESS SYSTEM OPTIONS After investigated the current system, the analyst need to decide an overall design of the system. To do this, analyst must use outputs of the previous stages and develops a set of business systems options. These are some different ways to produce a new system, throwing out the old system; the analyst may have brainstorming session to generate various ideas as possible. These ideas are collected to options, which are presented to the user. The options consider the following: • The degree of automation • The boundary between the system and the users • The distribution of the system, for example, is it centralized to one office or spread out across several? • Cost/benefit • Impact of the new system Where necessary, the option will be documented with a
