For each feature team, developers are chosen on an ad hoc basis to best serve different feature development requirements. Feature teams are responsible for developing and implementing features assigned to them and complete their part of module or component, contributing to the project development at large. Domain object modeling, developing by feature, individual accountability, feature teams, inspections, definition of feature-driven development configuration management, regular build schedule, and progress reports. After a successful design inspection for each activity to produce a feature is planned, the class owners develop code for their classes. After unit testing and successful code inspection, the completed feature is promoted to the main build. After the feature list had been completed, the next step was to produce the development plan.
An Architect is the one who designs the system, and the chief architect handles a team of Architects. As a result, they both came up with a method which was called Feature Driven Development. They took help from 50 other programmers and delivered 2000 functioning features in 15 months. Jeff de Luca may not believe in collective class or code ownership, but he’s far outnumbered by agile proponents who do. When these are done, all models are reviewed to come up with the initial model for the next steps. This can be one of the models or one that is a composite of one or more of the individual team’s models.
It’s hard for one developer or very few people to take on the various roles without help. Feature Driven Development has less written documentation, which can lead to confusion. Also, it is highly dependent on lead developers or programmers. Moreover, FDD is an excellent solution for big and complex projects, especially in critical situations.

In the first stage, the development team cooperates and builds an object model of the domain problem. The primary goal is to propose a model for the area domain. Once the team proposes their model, the chief architect selects one of these models or a merge of models, and it becomes the model created for that domain area. As a result, the team gets a clear image of the entire project.
If your business produces and sells physical products, then you need to make sure that they are produced to a high standard. If your products don’t meet industry quality standards, you could get… Chief Programmer plays many roles like coordinator, lead designer, and mentor. Playing multiple roles in a large size project is an issue as it increases the chances of human mistakes.
Managers steer a project using frequent, appropriate, and accurate progress reporting from all levels inside and outside the project based on completed work. Vipin Jain is the Co-Founder and CEO at Konstant Infosolutions and is in charge of marketing, project management, administration and R&D at the company. Here is everything you need to know about feature driven development..
It is needed to be up-to-date so that the client knows the latest, accurate, and frequent progress throughout the project. In addition to the above, it ensures that the developing team always has a demonstrable system ready. Identifying the domain object model, or the scope of the problem that needs to be solved, to help with the framework for feature development. Feature driven development is an iterative agile software development model. More specifically, FDD organizes workflow based on which features need to be developed next. The feature driven development put the features in place of requirements.
Moreover, the Class owner does the Design and then design the inspection of each class. In addition to the above, this will be a small problem to solve as compared to the last subset. The object model with all attributes and new and updated classes is ready.
- With FDD, teams rely on the internal documentation which is exchanged as part of the project strategy.
- Feature Driven Development has less written documentation, which can lead to confusion.
- FDD additionally takes a shorter sprint length than in Scrum.
- After its success, it was used on a second, 18-month long, 250-person product.
- Because every class of the function belongs to a specific developer, there is always someone responsible for all classes.
- Identifying the domain object model, or the scope of the problem that needs to be solved, to help with the framework for feature development.
During Feature Driven Development, some pre-work takes place before the development begins. The team and the developers have to agree on the general technical approach, discuss the technology, terminology, testing necessary action and create a live environment. Feature Driven Development doesn’t work efficiently for smaller projects. It also doesn’t work for projects where there is only one developer.

According to Jeff De Luca — FDD’s founding father — the overall model acts as a draft, capturing the vision of the product but not a lot else. Domain experts – the experts of the feature’s domain like user or client. The developers follow the guidelines and work to deliver the features. Based on the above step, create a list of the required features that are user-centric. Work Management Automate your process, organize the team, and gain complete control over deadlines.
It maintains a history of a Class as they undergo development. As a result, they help in identifying the latest version of source code files. As a result, a feature team remains small because the feature size is small.
History of feature driven development (FDD)
The concepts involved in these activities are explained in Table 3. Now, the reason it is called Feature Driven Development is because the project is divided into features or simplified and assorted pieces of client-valued functions. These functions follow a typical coding pattern which goes as . This could be applied in expressions like “Calculate the total sale”, “Authenticate user password”, and “Authorize the sale transaction”. One of the most striking features of FDD is class ownership.
In addition to the above, this feature team owns all the functionalities required in this feature. Therefore, it reduces the dependency on any other team, and every feature team wholly owns its feature. Feature-driven development is an iterative and incremental software development process. It is one of a number of Agile methods for developing software and forms part of the Agile Alliance. FDD blends a number of industry-recognized best practices into a cohesive whole. These practices are all driven from a client-valued functionality perspective.
Feature-Driven Development
One or more of the proposed models are selected to become the model for each domain area. Domain area models are progressively merged into an overall model. Quite contrasting to its simplistic appearance, Feature Driven Development methodology is comprehensive in its scope and range of offerings. Which makes it a lot relevant and companionable for different project needs as it is easy to adopt and refer to. The best part is, the comprehensive reporting mechanism FDD allows you to put up with, keeps everyone in the loop. With these the whole scheme of feature-augmented approach that FDD aims to offer, today renders into a refined process of development which is dubbed as FDD project lifecycle.
The second process incorporates Coad’s ideas of using a feature list to manage functional requirements and development tasks. The other processes are a result of Jeff De Luca’s experience. There have been several implementations of FDD since its successful use on the Singapore project. Chief programmer is an experienced developer who assists teams with analysis and design during the design and build steps.
Class ownership has been done by ordering and assigning features as classes to chief programmers. FDD is a model-driven short-iteration process that consists of five basic activities. For accurate state reporting and keeping track of the software development project, milestones that mark the progress made on each feature are defined.
What is Feature Driven Development (FDD)?
During the FDD proces, a function should be delivered every two to ten days. The FDD approach also places more value on documentation for internal use than other methods such as Extreme Programming and Scrum. This makes it easier to deliver the right https://globalcloudteam.com/ functionalities and to adjust the system. Individual ownership means that different pieces of work, or a piece of code, are assigned to an owner. He or she is responsible for the execution, and needs to guarantee the quality and the performances.
What Are the Stages of Feature Driven Development?
In addition, there is a focus on providing the customer with updates and interim results at any time. He was trying to provide a software development solution to a bank. It emphasizes features that are useful to software owners.
In other words, that project splits into multiple features; each feature is divided further until it is as small as it can be worked out. Additionally, this is done to ensure that its delivery can happen in 2-10 days. Digité provides Artificial Intelligence-driven project/ work management solutions. We empower your teams to do their best work with our innovative products.
It’s like starting a Scrum project with a fully filled product backlog. Development time estimates — you don’t want to leave the biggest features for last. Plan out each feature- Features are organized by how long they take to create and how important they are to the client. Go into too much feature-heavy detail at an early phase, and you may miss other opportunities that arise.
After the feature list is completed, the next step is to produce the development plan and assign ownership of features as classes to programmers. FDD promotes the method of development that focuses on developing features one-by-one in an incremental pattern. This allows developers to ascertain and achieve tangible results in short span of time, which in this case is ideally a two-week time.
When embraced successfully, FDD can speed up development time and make space for continuous improvement to software releases, by leading teams through five key stages of development. The teams had to release a brand new site and code within 28 days. The site mouse breaker allows users to play any flash games.
This is an important responsibility for the project manager. It is important that during this inspection defects are identified, which otherwise would have surfaced much later. After the team has started to work, the domain expert focuses on the analysing and development of the solutions for every function.
