Information systems assignment evaluating the hierarchy of information systems diagram

Question

Task: Can you populate a hierarchy of information systems and describe these individual systems and their relationships to each other in your information systems assignment?

Answer

Information systems assignment on the hierarchy of Information systems
• The decision-support system is based on the top of the hierarchy
• Both the MIS and ESS in the information systems assignment, having a similar level of functionalities, are placed below the DSS
• The TPS is arranged in the information systems assignmentat the lower base of the diagram that consists of the operational management process

The hierarchy diagram of the information systems assignmentshows the DSS at the top of the hierarchy as the system helps in strategic management. The MIS and ESS systems supporting tactical management are placed side by side below the DSS. The base of the diagram in the information systems assignmentconsists of TPS that determines the operational management process.

MIS
• The inputs are external data sources such as stakeholder data, and the outputs are reports like scheduled and demand reports.
• The purpose is to provide vital information to managers to ensure management functions (Usman and Ogwueleka, 2018).
• The MIS output is used as input in DSS, and the TPS output is used as input in MIS. The inputs to the MIS are the data of customers, suppliers, and other stakeholders. The output of MIS are the reports like demand report, exception report, scheduled report, key indicator report, and drill down information systems assignment. The purpose of MIS is to support management functions such as planning, organising, controlling, and decision-making. The MIS system output is used as input in DSS, and the output of TPS is used as input in MIS.

DSS in the information systems assignment
• Inputs are information analysed, such as reports and documents related to management functions, and the outputs are decisions generated by the system.
• The purpose is to develop decisions to support the organisational management process (Phillips-Wren, Power, and Mora, 2019).
• DSS uses the output of MIS, ESS, and TPS to ensure decision-making

The DSS helps to develop outputs for strategic management. The reports generated by MIS, ESS, and TPS are used by DSS to support decisions. The purpose of DSS is to ensure effective decision-making for strategic management.

TPS
• Inputs are secured data from source documents, and outputs are reports of transactions.
• The purpose is to develop awareness about transactions to ensure operational management (Mahato and Singh, 2022).
• The outputs of TPS are used as inputs in MIS, ESS, and DSS

The TPS inputs the data from the source documents, which helps it to produce outputs such as detail reports, exception reports, and summary reports. The TPS helps produce reports to support the operational management process. The outputs of TPS are used as inputs in ESS, MIS, and DSS.

ESS
• The inputs of ESS are the external and internal information, and the outputs are reports for shooting decisions of executives.
• The purpose is to support the executive decisions related to management
• TPS outputs are used as inputs in ESS, and the outputs of ESS are used in DSS

The ESS uses external and internal information related to management as input. The ESS output helps generate reports that can help in the executive decision-making process. The ESS generates outputs for DSS and uses the outputs of TPS as input.
Summary of possible benefits concerning ERP in the information systems assignment
• The ESS, MIS, and DSS system replacement by ERP
• One centralised location of ERP to gather, store, and evaluate the information for decision-making (Syreyshchikova et al., 2020).
• ERP supports useful report making
The ERP system can replace the MIS, ESS, and DSS as it acts as a centralised location to manage data. It stores and collects data for report generation and supports decision-making processes. As per the information systems assignmentthe one-step solution may ensure benefits in functions management.
