1. Acceptance testing is? A. running the system with line data by the actual user 2. Which are the tools not used for System Analysis? C. System - test data 3. In the system concepts, the term Integration D. refers to the manner in which each component functions with other components of the system 4. Problem analysis is done during C. systems analysis phase 5. System prototyping helps the designer in A. Communicating to the user, quickly, how the system, when developed, will look like and get feedback. System analysts can use many graphical tools to understand user requirements. Data flow diagrams (DFDs): DFDs are graphical representations of data flow through a system. They can be used to show the different entities that interact with the system, the data that is exchanged between them, and the processes that are performed on the data. Decision tables: Decision tables are a tabular representation of the logical decisions that a system makes. They can be used to show the different conditions that can occur, the actions that are taken based on those conditions, and the resulting outputs. Flowcharts: Flowcharts are graphical representations of the flow of control through a system. They can be used to show the different steps that are performed in a process, the decisions that are made, and the data that is used. Use cases: Use cases are a graphical representation of the interactions between a system and its users. They can be used to show the different tasks that users can perform in the system, the data that is used, and the results that are produced. Entity-relationship diagrams (ERDs): ERDs are graphical representations of the entities and relationships that exist in a system. They can be used to show the different types of data that are stored in the system, the relationships between those data types, and the constraints that apply to those relationships. The initial two steps followed by a systems analyst when he is requested to design an information system are: Feasibility analysis: This is the process of determining whether the proposed system is feasible. This includes assessing the technical, economic, and operational feasibility of the system. Systems analysis: This is the process of understanding the current system and identifying its requirements. This includes gathering information about the current system, its users, and its environment. Here are 5 effective skills of a systems analyst: Communication: Systems analysts need to be able to communicate effectively with a variety of stakeholders, including users, management, and technical staff. They need to be able to understand the needs of the users, translate those needs into technical requirements, and communicate the benefits of the system to management. [Example] A systems analyst is communicating with the users to understand their needs and requirements for the new system. The analyst is also communicating with management to keep them updated on the progress of the project and the benefits of the new system. Problem-solving: Systems analysts need to be able to identify and solve problems. They need to be able to think critically and creatively to come up with solutions that meet the needs of the users and the organization. [Example] A systems analyst is identifying and solving problems with the current system. The analyst is also identifying opportunities to improve the system and make it more efficient. Technical skills: Systems analysts need to have a strong understanding of technical concepts, such as data structures, programming languages, and software development methodologies. They need to be able to understand the technical requirements of the system and translate those requirements into technical specifications. [Example] A systems analyst is working with a team of developers to design and implement the new system. The analyst is providing technical guidance to the team and ensures that the system meets the technical requirements. Business skills: Systems analysts need to have a strong understanding of business concepts, such as organizational structure, business processes, and financial management. They need to be able to understand the business needs of the organization and to design systems that meet those needs. [Example] A systems analyst is working with a team of business analysts to understand the business needs of the organization. The analyst is also working with management to ensure that the system meets the financial and strategic goals of the organization. Project management skills: Systems analysts need to be able to manage projects effectively. They need to be able to plan, organize, and execute projects on time and within budget. They also need to be able to manage risks and resolve problems. [Example] A systems analyst is managing a project to develop a new system. The analyst is responsible for planning the project, organizing the team, and ensuring that the project is completed on time and within budget. Software versioning is the process of assigning unique version names or numbers to unique states of computer software. Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software. Here are some of the best strategies for transitioning system, based on my own experience and understanding: Planning: The first step is to plan the transition carefully. This includes identifying the goals of the transition, the timeline, and the resources that will be needed. Communication: It is important to communicate with all stakeholders throughout the transition process. This includes users, management, and technical staff. Testing: The new system should be tested thoroughly before it is rolled out to users. This will help to identify any problems and to ensure that the system is ready for use. Training: Users should be trained on the new system before it is rolled out. This will help them to use the system effectively and to avoid problems. Monitoring: The new system should be monitored after it is rolled out. This will help to identify any problems that may arise and to make necessary adjustments.
