MIS and System Analysis
Each system within the MIS plays a role which contributes to the accomplishment of the MIS objective. The data entities and attributes are considered completely keeping in view the needs of the system in question and their interface with other systems. The MIS may call for an open system design. In such a case while making the systems analysis and design, the aspect of open system design is In such a case while making the systems analysis and design.
The difference is in the development cycle time, quality of information, efficiency of design and the ease of maintenance of the system.
Tools and Techniques of System Analysis
A grid chart analysis is useful in eliminating unnecessary reports or unnecessary data items from reports. It can also be used for identifying responsibilities of various managers for a particular sub-system. Rather than directly describing the overall behaviour of the system, the simulation model describes the operation of the system in terms of individual events of the individual components of the system. In particular, the system is divided into elements whose behaviour can be predicted, at least in terms of probability distributions, for each of the various possible states of the system and its inputs.
After constructing the model, it is then activated in order to simulate the actual operation of the system and record its aggregate behaviour. Thus, simulation typically is nothing more or less than the technique of performing sampling experiments on the model of the system. The experiments are done on the model rather than on the real system itself only because the experiments on the real system would be too inconvenient, expensive and time consuming. A system flow chart is a diagram or pictorial representation of the logical flow of operations and information in an organisation.
It depicts the relationship between input processing and output considering the entire system. A standard set of symbols is generally used for construction of system flow charts.
