Information Systems For Business And Their Applications

In today’s world, information technology has become a fundamental requirement for the survival of most businesses. Indeed, some businesses are defined by the information systems and technology they use and some businesses would not exist if not for information technology. One such example is eBay: eBay is highly dependent on its systems and any breakdown or failure of these systems would potentially bring a halt to its operations.
There are many information systems used by businesses today; some systems serve general purposes while others may be customized to meet the specific needs of a particular business. Let us examine a few of the most frequently used information systems in organizations.
Transaction Processing Systems
These are systems that record the routine, day-to-day activities of the business. Examples of TPS include Sales Order Processing Systems and Materials Resource Planning Systems.
Systems for Business Intelligence
These include Management Information Systems (MIS), Decision Support Systems (DSS) and Executive Support Systems (ESS). These systems support the information needs regading IT project cost estimation of the middle and upper level managers of an organization.
Enterprise Systems
Types of enterprise systems include Enterprise Resource Planning Systems (ERPS), Knowledge Management Systems (KMS), Supply Chain Management Systems (SCMS) and Customer Relationship Management Systems (CRMS).
Enterprise Resource Planning Systems (ERPS) are systems that seek to link all the functions of an organization in order to allow the business processes of the organization to be fully integrated. Knowledge Management Systems (KMS) allow an organization to better capture and apply knowledge and expertise in an organization. Supply Chain Management Systems (SCMS) help an organization to manage its relationships with its suppliers while Customer Relationship Management Systems (CRMS) help an organization to manage its relationships with its customers.
There are even information systems for project management, called Project Management Systems (PMS). These systems allow the business to manage all aspects of a project, from creating the project plan, estimating resource, cost and time requirements and effective allocation of resources. Management of complex projects are nearly impossible without the use of such information systems. IT project forecasting, planning and execution in particular, would be extremely tedious and difficult without the use of such systems.
Therefore, it is clear that the impact of information systems on businesses today is enormous. It is safe to say that advances in technology will continue to be catalysts for changes in how businesses operate and how they interact with their environment. In a world where technology is advancing faster and faster all the time, businesses that wish to stay competitive need to be dynamic and be open to the influences of these advancements in technology.
