In software development, the V-model [2] represents a development process that may be considered an extension of the waterfall model and is an example of the more general V-model. Instead of moving down linearly, the process steps are bent upwards after the coding phase, to form the typical V shape.
Visionary has the most accurate perception of the business objectives of the system and the project. Another task is to supervise and keep the development process in the right track. Ambassador user: Brings the knowledge of the user community into the project, ensures that the developers receive enough user feedback during the development process.
The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental , waterfall , or evolutionary prototyping .
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
The emphasis on iterative models is that software development is a knowledge-intensive process and that things like analysis can't really be completely understood without understanding design issues, that coding issues can affect design, that testing can yield information about how the code or even the design should be modified, etc. [2]
A simplified version of a typical iteration cycle in agile project management. The basic idea behind this method is to develop a system through repeated cycles (iterative) and in smaller portions at a time (incremental), allowing software developers to take advantage of what was learned during development of earlier parts or versions of the system.
When problem analysis is incorporated into the software development process, the software development lifecycle starts with the problem analyst, who studies the situation and: creates a context diagram; gathers a list of requirements and adds a requirements oval to the context diagram, creating a grand "all-in-one" problem diagram.
This is a list of approaches, styles, methodologies, and philosophies in software development and engineering. It also contains programming paradigms, software development methodologies, software development processes, and single practices, principles, and laws.
