What are the six main reasons for systems requests?
The main reasons for system requests are: improved service, better performance, support for new products and services, more information, strong controls sand reduce cost..
What are the 3 types of systems?
Systems can be classified as open, closed, or isolated. Open systems allow energy and mass to pass across the system boundary. A closed system allows energy but not mass across its system boundary. An isolated system allows neither mass or energy to pass across the system boundary.
What is the importance of system analysis?
System analysis is important because it provides an avenue for solutions in the system through the various tasks involved in doing the analysis. Through these various tasks, the overall quality of a system can be easily modified or improved and occurrences of errors can ultimately be reduced.
What is the purpose of the system analysis phase?
It is a process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components. System analysis is conducted for the purpose of studying a system or its parts in order to identify its objectives.
What are the components of system design?
System design is the process of designing the elements of a system such as the architecture, modules and components, the different interfaces of those components and the data that goes through that system.
