Is life cycle Essay

The life cycle of information systems impact the organization in several ways and can be summed as follows: †¢ System investigation: The primary analysis of the system is essential for enveloping all the business data and information requirements to map all processes in the organization (Hoffer, 2002). It is done so that no data is left out and there is 100% coverage of the business requirements. The requirements of this stage demand enough expertise and skill to effectively understand and capitalize on information so that information is captured to its full swing. †¢ Systems analysis and Design: Once all the requirements are collected successfully they are analyzed to their importance and framed into defined design models such as DFD, E-R diagram and others so that their modeling is successfully transformed into a working system (Navathe, 2004). The entire design reflects the working of the organizational processes and their penetrations with external forces. The capabilities of this stage demands business modeling methods and strategies for developing a suitable data flow diagram to correctly figure out the process. †¢ Systems coding: This is the actual step where the business requirements are actually implemented and taken care to be given a representation. The impact of this stage would result in greater understanding of the business methods and good communication skills with the client. This stage creates an impact to make a difference to code the system to exact requirements mapped in the planning stages. †¢ Systems implementation: Successful implementation of the system is essential for the system to facilitate working and for the users to take full advantage of the system. The impact of this stage is quite large as improper implementation strategies may affect the working of the organization and processing capabilities. The above four stages impact the working of the organization as they are directly related to create a system to map the organizational processes. References Hoffer (2002).
