MIS AND SYSTEM ANALYSIS
MIS AND SYSTEM ANALYSIS
System analysis plays a central role in the development of MIS. Since the MIS is a corporation of the various systems, a systematic approach in its development helps in achieving the objective of the MIS. Each system within the MIS plays a role which contributes to the accomplishment of the MIS objective.
The tools of the system analysis and the method of development enforce discipline on the designer to follow the steps strictly as stipulated. The possibility of a mistake or inadvertence is almost ruled out. The system analysis with its structural analysis and design approach ensures appropriate coverage of the subsystems. The data entities and attributes are considered completely keeping in view the needs of the systems in question and their interface with other systems.
The systems analysis begins with the output design which itself ensures that the information needs are considered and displayed in the appropriate report or screen format; the subsequent design steps are taken to fulfill these needs.
The MIS may call for open system design. In such a case while making the systems analysis and design, the aspect of the open system design is considered and necessary modification are introduced in the designed the information system.
The user’s application in the system development ensures the attention to the smaller details in the design. The users actively come out with their requirements automatically ensuring that the users are met more precisely.
The systems analysis and designs, as a tool of the MIS development, helps in streamlining the procedures of the company to the current needs of the business and information objectives. New transactio0ns, new documents, new procedures are brought in to make the system more efficient before it is designed.
The SAD exercise considers testing the feasibility of the system as an important step. This step, many times, saves the implementation of inefficient systems. Sometimes it forces the management and analysts to look into the requirement and its genuineness. The MIS development process largely relies on the systems analysis and design as a source of the scientific development of the MIS.
The development of the MIS in today advance information technology and internet, web environment is a challenge. The nature of the system analysis has undergone a change, while the core process of the analysis and development has remained the same.
The system analysis is not restricted to the data-process-output. It also covers the technologies which enable the process feasibly. The subject now covers the analysis of interfacing and supports the technologies and it’s fitting into a chosen hardware-software platforms for a core system development. The MIS largely depends on how these technologies are bladed with the main system. The system architecture of the MIS is now different due to the high tech involvement of the data capture, communication, and processing technologies. The trend is towards more swift data capture and making it available in the fastest possible time leaving its usage to the user.
The development methodology may be the predictable design of data, databases and file approach or object-oriented analysis and design approach. The MIS design is the same, the difference is in the development cycle time, quality of information efficiency of design and the case of maintenance of the system.
