Use the information assembled in the first step to create a list of the required features. Remember, a feature is a client-valued output. Enter: Tasks. Analyze the complexity of each feature and plan tasks that are related for team members to accomplish. During the planning stage, all members of the team should take part in the evaluation of features with the perspective of each development stage in mind. Then, use the assessment of complexity to determine the order in which each feature will implemented, as well as the team members that will be assigned to each feature set.
This stage should also identify class owners, individual developers who are assigned to classes. Because every class of the developing feature belongs to a specific developer, someone is responsible for the conceptual principles of that class, and should changes be required to multiple classes, then collaboration is necessary between the owners of each to implement them. And while class owners are important to FDD, so are feature teams. In feature teams, specific roles are defined, and a variety of viewpoints are encouraged.
This ensures that design decisions consider multiple thoughts and perspectives. A chief programmer will determine the feature that will be designed and build.
He or she will also determine the class owners and feature teams involved, while defining the feature priorities. Part of the group might be working on technical design, while others work on framework. By the end of the design stage, a design review is completed by the whole team before moving forward. This step implements all the necessary items that will support the design. FDD provides greater accuracy in cost estimation of the project due to feature segmentation.
Disadvantages of FDD This agile practice is not good for smaller projects. There is high dependency on lead programmers, designers and mentors. There is lack of documentation which can create an issue afterwards. Previous complx.

In addition to the above, this method finds a solution to significant and challenging problems. It's a framework which. The Values of a framework are the values that make that framework different from others.
There are a few values that are important and affect all the aspects. There is a story behind the development of FDD. In , Jeff De Luca was the project manager for a Bank in Singapore for a considerably large scale and very critical project.
While working on that project, Jeff stuck on exceptionally complex problems. Despite using all the techniques available, the question remained as is. Finally, Jeff hired Coad, who was a developer. 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 functioning features in 15 months. Any project can use this method. 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 days. The people related to the project are the most crucial part of the system. Project Manager is responsible for sharing progress reports with the client and ensuring that the project is progressing as required. In addition to this, one project manager can manage more than one project. Project Manager's responsibilities include:. An Architect is the one who designs the system, and the chief architect handles a team of Architects.
In a small scale project, it can be one person as well. Development Manager is the one who handles the team of developers and ensures that they finish their job on time.
They may handle more than one project or team at a time. The chief programmer is one of the most experienced Programmers. The chief programmer handles one particular project at a time. Class is the smallest set of feature development which develops in a maximum of two weeks. The Class Owners are the developers who create features.
In addition to this, they take guidance from the Chief programmer and send progress reports to the Development Manager. The domain expert can be anyone who has the best knowledge of that particular domain and can help Teams to gain an understanding of it.
For example, in school, we have different teachers for different subjects, and not one teacher can teach all the subjects. In that case, every subject is a domain, and the subject teacher is a domain expert. The designing of FDD happened when the rest of the frameworks were not working for Jeff. This framework is a combination of best practices from other software development frameworks. We need to understand a few terms like what is a feature and how do we develop by feature before understanding the practices followed in FDD.
To understand the feature , we first need to understand the function. The client wants the development team to develop software. Clients would wish to have certain features in the software, and those features will have respective functionalities.
These functionalities are known as Functions. In Feature Driven Development FDD , a feature can be developed and delivered to the customer within one or two weeks, depending on the team size and feature complexity. Now in MS office, the client would wish to have:. These are different features of the software. One of the features MS word will have is various functionalities like insert, changing layout, changing view.
These functionalities further divide as:. Any function that is difficult to develop and not deliverable in this short span 2 weeks further divides into smaller functions.
This process goes on until the function is not small enough to be delivered in a maximum of 2 weeks. To sum up, since we know what the functions and features are, let's talk about the Practices FDD follows.
