Problem Identification

At this stage of system analysis, the analyst defines the task memunyai system problems, perform feasibility studies, and analyzing systems needs to be developed. There are three key questions to be answered, namely:
  1. What a problem to be solved by information system?
  2. What causes the problem?
  3. Who would be the end-user system?

Problem is the system analyst who studied the problems facing users. By studying this problem, the analysts work with users to get a rough problem. The steps that must be addressed:
  1. Defining the scope and objectives.
  2. Defining the problem facing the user.
  3. Identifying the cause of the problem and the decision point.
  4. Identifying the end user.
  5. Select the priority handling of the problem.
  6. Estimating costs and benefits roughly.
  7. Make a report defining the problem.

Important Meaning of Analysis Phase

Lots of good information systems users eventually abandoned because the system did not have anal sex is a true understanding of the organization. Objectives and systems analysis is to avoid this condition, by answering the following questions:
  1. Who will use the system?
  2. The system developed will be like what?
  3. What can the system work?
  4. When the system will be used?

Analysis phase itself will be divided into several stages of analysis in more detail, namely the old system weaknesses analysis, analysis of the needs of the new system, and a feasibility study covering technical feasibility, operational, economic, legal, organizational, and schedules. In the analysis of weaknesses of the old system, the focus of analysis adalab old system will be replaced with the new system. Analyses were performed to identify the weaknesses in business processes and ensure that there is a new system can overcome these weaknesses. Having compiled a list of weaknesses, the new system needs analysis conducted. In this analysis the need for new information systems are defined and proposed. Needs of proposed and tested its feasibility with several feasibility studies such as technical feasibility, technical, operational, economic, legal, organizational and schedules. If the need for the proposed feasibility study passed the stage of design can be implemented and system specifications are defined.

Analysis is an early stage in the development of systems and is a fundamental step that will determine the quality of the information system is developed. Information system analysis is divided into three stages of analysis: weaknesses in the system is running, needs a new system and the feasibility of the system which includes engineering feasibility, legal, economic, operational, and others.
