Incremental Model
Incremental build model is a method of software development where the model is designed, implemented and tested incrementally (a little more is added each time) until the product is finished. The product is announced as complete when it satisfies all of the requirements.
Various methods like this one (incremental method) are acceptable for combining linear and iterative system development methodologies, with the primary objective of each being to reduce inherent project risk by breaking a project into smaller segments and providing more ease of change during the development process:
• A series of mini-Waterfalls are performed, where all phases of the Waterfall development model are completed for a small part of the system, before proceeding to the next increment.
OR.
• Overall requirements are defined before proceeding to evolutionary, mini-Waterfall
Development of individual increments of the system:
OR
• The initial software concept, requirements analysis, and design of architecture and system core are defined using the Waterfall approach, followed by iterative Prototyping, which culminates in installation of the final prototype (i.e., working system).
This methodology include the following processes
Analysis
System analysis refines project goals into defined functions and operation of the intended application and analyse end-user information needs.
Design
This stage was describes desired features and operations in detail, including business rules, process diagrams, screen layouts, pseudo code and documentation.
Code
At this stage this is where the programmer comes in and codes the program.
Test
This part of the model the tests are done. The system analyst will have plan to test the system in the organization or company.
After this process implementation and maintenance will be done. The system will be implemented to the company and installed, this is where users will be trained and the new system will be maintained until it is on the clear for any new errors.
