Study Notes
Business Information Management - Week 10 (Lecture 1)
- Systems development, also known as the application development lifecycle, is a process used in systems engineering, information systems and software engineering. It involves planning, creating, testing, and deploying an information system.
- A software lifecycle model is a standardized format for planning, organizing, and running a new development project.
- A lifecycle model describes the activities carried out in a software engineering project and their relative order.
- Many different lifecycle models exist, some being variations of a small number of basic models.
- Software engineering projects typically have a fixed budget, and time constraints are often crucial. Other issues, like staff availability, are also project constraints.
- Project planning involves scheduling activities across time, space, and personnel to optimize factors like project risk, profit, customer satisfaction, worker satisfaction, and long-term company goals.
- A project plan necessitates a description of needed resources (people, money, and equipment), dependencies and timetables, and delivery rates. It's impossible to measure progress without a reference plan.
- Software engineering projects, unlike some other engineering fields, lack physical visibility. This necessitates using deliverables to track progress, such as design documents, prototypes, reports, project/status meetings, and client surveys.
- Systems development projects are difficult and often fail in terms of time, cost, and functionality. Failure rates have been reported in several studies.
- Common problems include poor communication, analysis or design quality, and management issues.
- Systems development phases include initiation, analysis, design, development, implementation, and maintenance. Each phase has a purpose, inputs, processes, and outputs.
- The initiation phase focuses on deciding on the system, with inputs like business rationale, and outputs like a go-no-go decision and a project plan.
- In the analysis phase, requirements are defined, using business and user requirements, leading to requirement specifications, goals, and testing plans.
- During the design phase, specifications are created by evaluating design options, and the outputs include system architecture and system design.
- Development implements the design in code and leads to the creation of the information system.
- Implementation focuses on deployment, using system components and a test plan. It includes installation, training, and data migration, ultimately leading to a live, active system.
- The maintenance phase keeps the system running, handles user input, and involves monitoring, software engineering, patches and training.
- The waterfall model is a lifecycle model that proceeds in a sequential way, moving from initiation to analysis, design, development, implementation, and maintenance in a linear format. This can be inflexible for projects with changing requirements.
- Prototyping is an approach to system development that involves building and testing small parts incrementally, adapting to feedback to improve the development process. It prioritizes user input and promotes adaptability.
