2. I don’t care about how you deal
with it, I just need the features
work fine.
-- Almost Clients --

3. (do) Action
(to get) Result
(of) Object

Feature
So, what is the feature ?

4. - Calculate the total of cart.
- Display the sliders of promotion.
- Get logged in Dashboard.
- Compare 2 products in wishlist.
- Detect fraud-transactions of users.
So, what is the feature ?

7. What is Feature-Driven Development ?
❏ Invented by Jeff De Luca in 1997
❏ An (lightweight || Agile) methods
❏ An (iterative && incremental)
software development process
❏ All driven from a client-valued
functionality perspective

8. OMG ! Features are everywhere !
How to deal with them ?

9. ----- It takes about 5 steps -----
How to deal with the whole features ?

10. Already aware scope, context and
requirements of system :
▪ Domain discovery
▪ Modeling work
▪ Modeling review
▪ Document study
Note : more Shape than Content

11. Domain > Subject Areas > Business
Activities > Categorized Feature List > Feature :
▪ (do) Action (to get) Result (of) Object
▪ if (feature->estimated_time > 2 * WEEK) {
feature->break_down_to_small_pieces();
}
Step 2 - Build feature list

12. Produce the development plan
▪ if (feature->estimated_time > 2 * WEEK) {
feature->break_down_to_small_pieces();
} else {
foreach (class in feature->classes) {
class->assign_for(programmer);
}
}
Step 3 - Plan by feature

13. Produce a design package for each
feature
1. Select small group of features
2. Make detailed sequence diagrams
3. Refine overall model
4. Write class & method prologues
5. Hold design inspection

14. Produce real-feature
if (feature->inspect_design() == SUCCESS) {
foreach (class in feature->classes) {
class->owner->develop_code().then(function() {
if (class->unit_test()&& class->inspec_code())
continue;
});
}
feature->promote_to_main_build();
}

15. FDD Project Lifecycle

16. To keep tracking and report
accurately state, FDD defines
6 milestones

17. Roles and Responsibility
Key Roles:
1. Project
Manager
2. Chief
Architect
3. Development
Manager
4. Chief
Programmer
5. Class Owner
6. Domain Expert
Supporting Roles:
1. Release
Manager
2. Language Guru
3. Build Engineer
4. Toolsmith
5. System
Administrator
Additional Roles:
1. Tester
2. Deployer
3. Technical
Writer
One team member can play many roles
and one role can be shared to many members.

18. Best Practices
Mechanism of FDD is almost likely
mechanism of GIT branch. So FDD is
the best way to combine with
decentralized version control like
GIT.

19. Git Feature Branches
Workflow

20. Pros :
★ Good to large projects
★ Progress
tracking/reporting
★ Frequent tangible
results
★ Flexible, strong with
GIT
★ Class, feature ownership
★ Concise processes
★ Emphasizes quality
★ Just enough design
initially
Pros & Cons of FDD
Cons :
➢ Not suitable with small
projects
➢ High reliance to chief
programmers
➢ Less written
documentations
