Components of an information system include software, hardware, infrastructure, and personnel 
that coordinate and control the decision-making process in an organization (Clayton). 
Information systems in business are viewed in three different dimensions; technology, 
management, and organizations. An information system is an integral part the larger 
organization. An organization is made of different levels of employees who take part in different 
organization's roles. Senior management, for instance, long-term strategic plans, middle 
management execute plans of the senior management, and operational managers monitor daily 
business activities. On the other hand, the mandate of the enterprise management is to make 
decisions, solve organization's problems, and allocate resources necessary to meet business 
goals. Finally, among the many tools management use to run the business is the information 
technology. The hardware part of the information system is the physical part while the software 
consists of instructions that control the computer hardware. 
The management invests in information systems for their ability to provide a real 
economic value of the business. Despite the huge technological investments made by businesses, 
the investment choice made determines the success of the business. A firm that makes a wise 
technological decision is able to outdo its competitors while those that make poor investment 
choices end up wasting resources. Therefore, there is a direct link between the performance of an 
organization and the information system invested in. This is because an information system will 
enable the management to efficiently execute business processes to meet business objectives and 
strategic plans. The information system acquired should have a direct impact on the business 
processes in terms of resource allocation, staff management, workflow management, and activity 
monitoring. An information system is meant to ensure efficiency while reducing operational 
costs.
