1. User Driven Development Improve your development process focusing on the user David González @dggonzalez david@novoda.com
2. Design Prototyping Scribbles Reviews Retrospectives User testing Beta releases Development Stakeholders
4. Designers are also nice people “ - Sebastiano Poggi Android Developer at Novoda
5. Paper prototyping is to find as much issues as possible before starting to develop
6. Paper allows you to do and redo without fear of losing development time The Sun Mobile News - Aug 2014
7. Scribbles are the minimum representation of an element
8. public class FeedItemView extends AspectRatioView { private TextView createdText; private TextView categoryText; public FeedItemView(Context ctx, AttributeSet attrs) { super(context, attrs); } @Override protected void onFinishInflate() { super.onFinishInflate(); inflate(getContext(), R.layout.feed_item, this); createdText = findById(this, R.id.feed_text_created); categoryText =findById(this, R.id.feed_text_category); } } Create a custom view
9. <ScrollView xmlns:android=“…” android:layout_width="match_parent" android:layout_height="match_parent" android:paddingTop="?android:attr/actionBarSize"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <com.newsuk.thesun.view.AspectRatioView android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/bg_article_top" /> <com.newsuk.thesun.view.AspectRatioView android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/bg_article_content" /> </LinearLayout> </ScrollView>
11. Iterate How do we do it from here?
12. Split the user journey in as few steps as possible
13. Guesstimate
15. Acceptance criteria
17. 5 points Scribble implementation with local data Given I am a logged in user And I have previously saved an article When I navigate to My Articles Then I should see a list of articles
18. 3 points Loading screen Given I have internet connection When I navigate to My articles Then the date should be fetched from the API And I should see a loading screen
19. 3 points Empty screen Given I have no saved articles When I navigate to My Articles Then I should see an empty screen
20. 8 points Scribble implementation fetching data from API Given I have internet connection When I navigate to My articles Then the date should be fetched from the API And I should see a list of saved articles
21. 5 points Visual design items Given I see a list of articles When I navigate to My articles Then the list items designs should match specifications
22. 5 points Interaction with articles Given I have a list of saved articles When I tap on the article header image Then I should see a selected item
23. 8 points Response from API Given I have a list of saved articles When I swipe away one of the elements Then the remote item should be deleted And I should be notified of the deletion
24. Design reviews It’s up to the design team to accept a visual design story
28. Code quality
33. Use Pull Request Builder and Thresholds in Jenkins to prevent Technical Debt
39. Sprint reviews, retrospectives and demos
42. Show what you achieved
43. Be transparent about what’s missing
44. Excite them about what’s coming
45. Usability testing
46. Acceptance criteria Define goals, what do you want to achieve?
47. Pilot tests highlight problems early and save your user’s time
48. Acceptance criteria Define action points, refine and test again
49. Nightly releases
