- What are the five phases in the systems development life cycle?
Five phases are mentioned below:
- Systems or project planning phase: In this stage, we check the feasibility of the project and plan accordingly
- Requirements gathering and analysis phase: In this phase, it is required to understand business needs and processing requirements.
- Design Phase: in this stage, it is required to define the solution based on the planning phase
- Implementation phase: in this stage, it is required to construct, test and install the new proposed system.
- Maintenance or support phase: This stage is continuous. It contains updates and ensures the smooth running of the system.
- What are the five major dimensions of the feasibility study?
The five dimensions are economic, technical, operational, scheduling and legal.
- What are three examples of activities performed during the planning phase?
In the planning phase, we define the business problem and devise a project schedule of financial, area, and transportation. Another example of an activity is to confirm the feasibility of the planned project. For example, we are checking economic, organizational, technical factors and ensuring proper work schedule. Another activity is to hire and select project members for launching the project.
- What are examples of three tasks involved in the requirements-gathering and analysis phase?
Following tasks are involved in requirement-gathering and analysis phase:
- Gathering information about the problem
- Building prototype or solutions for the problem
- Generating and evaluating alternative solutions to the problem.
- What are examples of three tasks performed during the design phase?
The three tasks are discussed below:
- Designing and integrating the network
- Designing the user interface and system interface
- Designing and integrating database, prototype and system controls.
- What are examples of three tasks performed during the implementation phase?
Following tasks are performed during the implementation phase:
- Constructing software components and verification
- Testing and converting data
- Training users and installing the system.
- What are examples of three tasks performed during the maintenance phase?
Following tasks are performed during the maintenance phase:
- Maintaining system
- Enhancing and improving systems
- Providing support for users.
- List four new trends in systems analysis and design.
These are the four new trends in system analysis and design:
- Extreme Programming (XP)
- Unified Process (UP)
- Agile Modeling and
- Scrum
