What is spiral model explain with diagram?
Spiral model is one of the most important Software Development Life Cycle models, which provides support for Risk Handling. In its diagrammatic representation, it looks like a spiral with many loops. The exact number of loops of the spiral is unknown and can vary from project to project.
Where is spiral model used?
The Spiral Model is widely used in the software industry as it is in sync with the natural development process of any product, i.e. learning with maturity which involves minimum risk for the customer as well as the development firms. When there is a budget constraint and risk evaluation is important.
How do you draw a spiral model?
- Draw a set of semicircular arcs. The easiest way to create a spiral diagram is by drawing and merging semi circular arcs. Go to Auto shapes and select the Arc tool.
- Group alternative arcs and flip them vertically. The next step is to select alternative arcs and color them red using ‘Shape Outline Color’ option.
What is the spiral shape?
A spiral is a coil or curl, like the shape of a piece of hair wound around your finger, a Slinky toy, or a corkscrew. A curve forming a series of circles that become gradually larger or smaller is one kind of spiral.
What is the advantage of spiral model?
Advantages of Spiral Model: Software is produced early in the software life cycle. Risk handling is one of important advantages of the Spiral model, it is best development model to follow due to the risk analysis and risk handling at every phase. Flexibility in requirements.
What is the function of a spiral?
A spiral is a curve formed by a point revolving around a fixed axis at an ever-increasing distance. It can be defined by a mathematical function which relates the distance of a point from its origin to the angle at which it is rotated. Some common spirals include the spiral of Archimedes and the hyperbolic spiral.
