Software Development Methodologies

Software Development Methodologies
The systems development life cycle (SDLC) is the traditional approach used by organizations to plan large IT projects, such as IT infrastructure. The SDLC is a structured framework that consists of sequential processes by which information systems are developed. Whether companies use a structured method such as the traditional waterfall approach or more agile methods, all development projects start with defining the requirements and design before building the system components.

Consider the following scenario:
Your school intends to develop a student management system. The system will need to hold all details of registered students, including personal information, courses taken, and examination grades.
Submit a 3- to 4-page paper that includes the following:

A description of the core activities in the software development process
An explanation of the distinction between systems analysis and systems design and a description of the activities involved in each
An explanation of the benefits of information systems
An explanation of what the information system’s requirements are
An explanation of why the information system’s requirements are difficult to determine correctly
An explanation of why the testing stage of systems development is so important.
An explanation of the difference between the three stages of testing for an information system
A description the role of programming, conversion, production, and maintenance in systems development
An evaluation of which of the three (programming conversion, production, and maintenance) is most important to project success and why
An explanation of which of the three (conversion, production and maintenance) is most difficult to do correctly and why
An analysis of the benefits and limitations of each of the following methods of building information systems: traditional waterfall method, prototyping, and component-based development
A recommendation for which method the school should use for developing a student management system and justification of your choice
