THE PHASES OF THE INCREMENTAL MODEL.

-

 

  1. REQUIREMENT GATHERING AND ANALYSIS.


In this phase, the requirements of the software are gathered and analyzed by the product analysis expertise. The requirements are then divided into smaller, more manageable parts that can be developed in increments. The requirement analysis team understands the system's functional requirements. To develop software under the incremental model, this phase performs a crucial role.


  1. DESIGN AND DEVELOPMENT.


In this phase, the design of the software is created based on the requirements. The design should be modular, with each module representing a part of the software that can be developed and tested independently. The design of the system functionality and the development method is finished with success. When software develops new practicality, the incremental model uses style and development phase.


  1. TESTING.


In this phase, testing is performed on each increment to ensure that it meets the requirements and functions correctly. The testing phase checks the performance of each existing function as well as additional functionality. In the testing phase, various methods are used to test the behaviour of each task.


  1. IMPLEMENTATION.


In this phase, the software is developed incrementally, with each increment building upon the previous one. Each increment is developed and tested independently. The implementation phase enables the coding phase of the development system. It involves the final coding that is designed in the designing and development phase and tests the functionality in the testing phase. After completion of this phase, the number of the product working is enhanced and upgraded up to the final system product.


After these main phases are completed, two more phases are looked at. They are:


  • INTEGRATION.


In this phase, the increments are integrated into the final software product.


  • MAINTENANCE.


In this phase, the software is maintained and updated as needed.

  The software development life cycle (SDLC) models provide a roadmap for navigating the challenging and complex software development process. The model used significantly impacts the project's quality, schedule, budget, and capacity to satisfy the needs of the stakeholders. More than 50 recognized SDLC models are now in use. Each has advantages and downsides for a particular software development project or team, and none is perfect. This blog will discuss one of the most well-liked models in depth. Iterations make up the incremental model's development process ("Lego-style" modular software design is required!). In each cycle, new software modules are added while making little to no changes to previously installed modules. Either sequentially or concurrently, the development process is possible. While numerous iterations of sequential development might lengthen and increase the cost of the project, parallel development increases delivery speed.

STAGED DELIVERY MODEL. Construction of only one part of the project at a time.  2. PARALLEL DEVELOPMENT MODEL. Different subsystems are developed at the same time. It can decrease the calendar time needed for the development, i.e. TTM (Time to Market) if enough resources are available.  There are four approaches to implementing the incremental model. They are: Top Down. The topmost software component is implemented first in a top-down approach. Like, the user interface of any software is its most vital component and is also its most noticeable aspect. Since it mimics the finished product, the customer can see how the user interface works. The top-down method operates in a breath-first manner. Bottom-Up. The lowest level of the software is implemented first in a bottom-up approach. The element on which everything depends is the lowest one. These elements could be classes that are reused or shared to create a shared library for an application. The disadvantage of the bottom-up technique,

DISADVANTAGES OF THE INCREMENTAL MODEL.

-
  Increased complexity: The incremental model can lead to increased complexity, as each increment must be integrated into the final product. Increased costs: The incremental model can lead to increased costs, as each increment requires additional development and testing. The cost here is higher than the cost in the Waterfall model. Team and planning: A good team and proper planned execution are required in using the incremental model.
