When upgrading what type of business information system you use at your company, everything has to be taken into account. As the saying goes, no stone goes unturned. If something is ignored or overlooked, it could potentially ruin the entire upgrade. No system is the same and one system won’t provide all the information for one agency.
What Are The Different Systems?
There will always be a collection of systems in place to take care of different actions. The different systems can be called either functional or constituency. Functional perspectives look at systems by the business function that they perform. Constituency perspectives look at systems through looking at the organization that they serve.
The four main information systems serving functional systems:
- Sales and Marketing – They can improve how the company monitors sales transactions, can analyze sales trends and effectiveness of marketing campaigns.
- Manufacturing and Production – It provides information about numbers of items available in inventory so that they can build more product without interruption.
- Finance and Accounting – Provides accounts receivable system to track and store customer data.
- Human Resources – Maintains data on company data supporting HR functions.
The four categories of constituency are:
- Transaction Processing Systems (TPS) – Basic systems serving at the operation level of companies. They record daily routine transactions needed to conduct business like sales receipts.
- Management Information Systems (MIS) – Support middle managers’ interests. Support through giving historical performance information to perform decision making actions at the management level. MIS and TPS data work together to build reports of basic operations.
- Decision Support Systems (DSS) – The business intelligence system. Helps managers with unique, fast changing and not easily found decisions that have to be made. For example, they might be used to help the manager to develop a bid on contracts.
- Executive Support Systems (ESS) – Used by senior managers to find answers to strategic issues and long-term trends in both the company and their environment. This type of system pools data from both internal and external sources, consolidating the data found into a form that is easy to use.
Integration and Implementation
In order for these systems to work correctly it is good to use them with others. For example, TPS is a major source of data for other systems while ESS is a recipient of data from external sources and lower systems. They all work together interdependently in some manner or another. But as it is, most businesses are starting to use new technologies that they create themselves. This better combines information from all the different systems mentioned beforehand, therefore making the said company more competitive.
