Feature-driven development is an iterative software development technique that prioritizes application features based on a company’s needs. It is based on short development cycles and templates, similar to Extreme Programming. The process includes four main areas: domain model, feature list, prioritization, and building and deploying features based on priority. This agile process delivers priority features to customers faster and allows for testing before the application is fully completed.
All software development requires project management and system development lifecycle management (SDLC). These are the techniques and processes used to effectively manage the development process of a software application. Feature-driven development is a technique based on rapid development cycles. It provides the enterprise with faster capabilities than typical off-the-shelf SLDC techniques.
In today’s competitive marketplace, it is important for organizations to react quickly to evolving market trends and climate. Information technology has attempted to evolve software development into a more agile process that can anticipate an organization’s competitive needs. Feature-driven development is a software development technique that attempts to implement application features iteratively based on a company’s priorities.
Feature-driven development is considered an iterative development process. This is because the code is developed and deployed in iterations of features rather than as a complete application. It was created by Jeff De Luca in 1997 as a fast technique for distributing software applications. This agile process attempts to deliver priority features to a customer faster.
The feature-based development process is based on templates and short development cycles. This is similar to the development techniques used in Extreme Programming (XP). Each project is broken down into small features that can be coded, tested and implemented in less than two weeks. This two-week cycle gives the business a feature-rich system that’s faster because it’s constantly evolving.
There are four main areas of feature-driven development. These are the domain model, the feature list, the plan by feature, and finally build and deploy by feature. These four areas have specific requirements and techniques that make them successful.
The domain model is a high-level overview and design of the entire application. It is the skeleton design of what will be built during the iteration process. This is the first step in the feature-driven process and is intended to provide the development team with a road map of the entire application.
Once the domain model is complete, you need to create a feature list. The feature list will include all required features of the application. Each feature must be designed in specific detail to make it work. An example of a feature for a banking application would be “calculate total available bank balance”.
Prioritization is the next step in feature-driven development. After the entire feature list is built, business users should prioritize it. This priority should be based on the importance of the feature to your organization.
The final phase of feature-based development is based on building and deploying features based on the priority feature list. Each feature will be coded, tested, and rolled out in two-week increments. This rapid iterative approach gives the business the opportunity to use the application before it is fully completed.
