Incremental Model:

Definition, Stages and Examples

Understanding the Incremental Model

The incremental model is a software development method that is carried out in stages. This model connects several elements of the iterative and linear sequential models, meaning that software or application development is carried out through several small, sequential stages.

Each stage produces a functional piece of software, but testing is necessary before use. This model always focuses on developing the software’s core features first, then gradually developing other features.

Understanding Incremental Model Types

There are several types of incremental models, and the following are the most frequently used types for software development.

Staged Delivery

This type of model always carries out complete software development in stages. Each stage produces functional components that are immediately usable by users. In this development process, developers typically create the login feature first, followed by other features.

Parallel Development

This development model involves working on several increments simultaneously, carried out by multiple teams to accelerate the development process. Once completed, the resulting increments are immediately combined to form a larger system.

Functional Increment

If anyone asks what an incremental model is, the answer is that it’s a software development model with various types, one of which is the functional increment. This type of development model is one in which each increment adds specific functionality to the system.

This model focuses on creating the parts of the software most needed by users first. For example, in developing store software, the features created first are ordering and payment.

Progressive Development

This type of development is one in which each stage enhances or even refines existing features. The main focus in this stage is to correct deficiencies in previous increments, resulting in a much better iteration of the system.

Understanding the Stages of the Incremental Model

There are four stages of the incremental model that must be completed to create quality software. Here are some examples:

Requirements Analysis

What is the incremental model? It’s an application development model, one of which is requirements analysis. This stage is crucial in the application or software development process.

The team conducting this stage gathers requirements, identifies requirements, and identifies objectives and challenges. In addition, the team will also identify the resources needed to complete the project.

Design and Development

In this phase, the team will develop a system design for the project, based on the previous SRS. After completing the design, the team will save the document as a Design Document Specification (DDS) and then submit it to stakeholders.

Coding

This phase begins after the submitted DDS has been approved. The development team will immediately create efficient coding to ensure smooth interaction between existing modules. During this phase, the team also creates a physical design.

Testing and Implementation

After coding, the development team immediately conducts testing to verify the effectiveness of the code. This testing includes application integration and environment testing.

The purpose of testing is to prevent errors during subsequent phases. After testing is complete, the implementation phase begins, integrating all existing modules so that the resulting product can be used.

Real-Life Examples of Incremental Models

There are many examples of incremental models, one example being the development of e-commerce applications. The increments used to develop the application are quite varied. During the initial development phase, the main feature, namely the product search feature, is created.

After that, subsequent increments are made, adding other features as needed by users, for example, adding a shopping cart, integrating with online payment methods, and adding tracking features. Once all of these are added, the application is tested and launched.

Advantages and Disadvantages of the Incremental Model

Developers who wish to use this development model must first understand the advantages and disadvantages of the incremental model. This model has many advantages, one of which is that requirements and needs are easily adjusted because application development is carried out in stages.

This development model also has disadvantages, namely, it requires very thorough planning to avoid problems during the application development phase. Furthermore, this development model also requires excellent team coordination to avoid miscommunication.
