systems life cycle 2024 with complete solution

Systems Development Life Cycle (SDLC) - correct answer also called waterfall development Systems Development Life Cycle (SDLC) - correct answer this consists of well-defined phases that are followed methodically. Systems Development Life Cycle (SDLC) - correct answer Most of the larger organizations use this process in their development to check if the requirements are followed, including its progress. Systems Life Cycle - correct answer is the oldest method when building information systems. Systems Life Cycle - correct answer It is a phased approach in creating or building a system by dividing systems development into formal stages. Systems Life Cycle - correct answer 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 Analysis - correct answer This is the first stage in a system life cycle that has certain steps to come up on the data. Systems Analysis - correct answer It requires analyzing the data, identifying the problems, and determining the information requirements and objectives of the system. Investigation - correct answer What is the business process needed to support a system? Investigation - correct answer What problems do you want to solve? Technical Feasibility Study - correct answer Is the technology available to create the system? Technical Feasibility Study - correct answer Which of the available technologies should be used? Economic Feasibility Study - correct answer What are the resources needed to implement the system? Economic Feasibility Study - correct answer Will the system's benefits outweigh its costs? Operational Feasibility Study - correct answer Will the system be used to its full capacity? Operational Feasibility Study - correct answer Will the system be used appropriately by its intended users? Requirements Definition - correct answer Does it support other systems such as web and mobile technologies? System Design - correct answer In this phase, the system design shows how the system will fulfill the objectives based on the requirements that have come up. System Design - correct answer 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. Data Flow Diagram (DFD) - correct answer________ symbols are suitable for describing any information systems (IS) even if this is not computer-based. Data Flow Diagram (DFD) - correct answer It helps pinpoint the weaknesses in an existing system. Data Flow Diagram (DFD) - correct answer While _____are easy to learn and use, these still have limitations like any diagramming method and cannot describe a system completely. Unified Modeling Language (UML) - correct answer is a graphical standard for visualizing, specifying, and documenting software. Unified Modeling Language (UML) - correct answer This tool helps developers to communicate and logically validate desired features in the design phases of software development projects. Unified Modeling Language (UML) - correct answer It consists of diagrams that describe the use case, class, interaction, activity, and physical components. Programming - correct answer In this stage, the system specifications that were prepared during the design stage are translated into program code or software. Testing - correct answer This phase is the most respected in systems development. Testing - correct answer doing this in each module in every simulation does not mean that the functionalities are in good condition; rather, it is important to test the entire system. Testing - correct answer It should include attempts to get the system to fail and to violate processes and security controls. unit testing, systems testing, and acceptance testing - correct answer Three testing that should be performed Delivery - correct answer In the new IS, implementation is referred to as _____________. Implementation - correct answer This consists of conversion and training. Conversion - correct answer this takes place when an operation in an organization switches from using an existing or old system to the new system. Production - correct answer When the new system is installed, it is said to be in ________. Production and Maintenance - correct answer 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. Production, maintenance - correct answer When the system is in ________, the errors will be corrected, meet all the requirements, or improve processing efficiency. If there are some changes or new requirements in software or hardware, or if there is an improvement of the process, it is called _________.
