System Boundaries

Every system consists of subsystems that have different objectives and interactions based on the given requirements. All subsystem uses the given resources to meet the given objective.

Subsystems

It refers to the connection of each system or subsystem boundaries and serves as the connection to display the output from one (1) system to the input of another system.

Subsystem Interface

Which best describes System Boundaries?

Every user of the system has a specific access on each module. For example, the person who is responsible for the inventory can only access the inventory module, while the manager has access to all the modules of the system.

This refers to the people, organizations, and other systems that give and receive data from the system.

System Environment

Transaction Procession System

"Supply chain refers to the sequence of activities. It includes marketing, manufacturing and assembly, packing and shipping, and billing and collection." What information system is being described?

Supply Chain Management System

"This system manages the relationship of the organization to its customer. Service representatives use this system to talk to their customers via phone." What information system is being described?

Customer Relationship Management System

"Most of the organizations use business intelligence systems to compete better with other organizations. This system accesses massive data, usually larger databases called data warehouses." What information system is being described?

Business Intelligence systems

"This system helps to find actions and answers most of the questions like "What if?"" What information system is being described?

Decision Support System

"This system uses artificial intelligence to be able to preserve the knowledge of an expert and to solve problems." What information system is being described?

Expert Support System

Also called waterfall development, consists of well-defined phasesthat are followed methodically. Most of the larger organizations use the SDLC process in their development to check if the requirements are followed, including its progress.

Systems Development Life Cycle (SDLC)

It is the oldest method when building information systems. It is a phased approach in creating or building a system by dividing systems development into formal stages. It is still used for large complex systems that require a formal requirements analysis, predefined specifications, and tight control in the process of creating a system.

Systems Life Cycle

This is the first stage in a system life cycle that has certain steps to come up on the data. It requires analyzing the data, identifying the problems, and determining the information requirements and objectives of the system.

Systems Analysis

• What is the business process needed to support a system? • What problems do you want to solve? What step in the Systems Analysis stage are these questions asked in creating a system?

Investigation

• Is the technology available to create the system? • Which of the available technologies should be used? What step in the Systems Analysis stage are these questions asked in creating a system?

Technical Feasibility Study

• What are the resources needed to implement the system? • Will the system’s benefits outweigh its costs? What step in the Systems Analysis stage are these questions asked in creating a system?

Economic Feasibility Study

• Will the system be used to its full capacity? • Will the system be used appropriately by its intended users? What step in the Systems Analysis stage are these questions asked in creating a system?

Operational Feasibility Study

• Does it support other systems such as web and mobile technologies? What step in the Systems Analysis stage are these questions asked in creating a system?

Requirements Definition

In this phase, this shows how the system will fulfill the objectives based on the requirements that have come up. The designer of the system will be responsible for giving the details of the system specification, which will deliver all the functions that have been identified in the system analysis phase.

System Design

Which statement is NOT TRUE about System Design Stage?

In this stage, the system specifications that were prepared during the design stage are translated into program code or software

In this stage, the system specifications that were prepared during the design stage are translated into program code or software.

Programming

This phase is the most respected in systems development.

Testing

Which statement is NOT TRUE about Testing Stage in System Life Cycle?

In this stage, the system specifications that were prepared during the design stage are translated into program code or software.

In the new IS, This is referred to as delivery.

Implementation

This takes place when an operation in an organization switches from using an existing or old system to the new system.

Conversion

In this stage, the system will be reviewed by both users and technical specialists to check if it meets the original objectives. If the system is fine and meets all the objectives, then it should be maintained.
