Software Engineering in the
Continuous Age

3. Delivering Software Products

4. 4
The Waterfall process maps to the way enterprises were organized:
• Requirements: Marketing and Product Managers
• Design: Architects and Designers
• Implementation: Software Engineers
• Verification: QA
• Maintenance: Operations

5. Waterfall -> Agile -> Continuous Delivery
5
Agile was born out of the need to shorten the feedback
loop. In most enterprises Agile is just fast Waterfall.
Agile transformed into Continuous Delivery as enterprises
changed. The roles are merging as the feedback cycle
becomes instantaneous.

6. 6
The perfect word to describe the age we’re in

7. Death of the Release Date set
Software Enterprises free!

8. 8
So we have arrived? Only incremental improvements from now on?

9. Not so fast…

10. 10
Continuous Delivery starts with a code change. What about the other stages
of Software Engineering: Requirements, Design, and Coding?

11. Requirements, Design, Coding:
Integral phases of Software
Engineering
11

12. 12
Engineering is about application, about designing, building, and
maintaining. It goes all the way from an idea, a thought, to working product.

13. Craftsmanship is the skill with which this is done –
the “how”.

15. We ask Software Engineers to be
experts and keep track of many
dimensions…

16. A Plethora of Languages, Platforms, and Frameworks…

Hadoop

17. … and many signals and tasks

tooling to make Software
Engineering easier and better.

20. Let’s use computing power and
tooling to make Software
Engineering easier and better.
Optimize for the software engineer, not the computer.

21. 1. Continuous Task Execution
21

22. Discrete -> Continuous
22
Input Action Output
Software automation tasks, a.k.a. “builds”, all follow the same basic pattern

23. gradle --continuous check rebel
play run
ember serve

Tooling is starting to support this:
https://docs.gradle.org/current/userguide/continuous_build.html

24. 2. Infinite Scalability
24

25. Infinite == AWS Scale
25
If you need more computing power than AWS can provide,
you’re doing something wrong!

26. AWS Price List: It’s Really Cheap!

27. The Need for Speed
Feedback in Human Time
27
The value of the feedback decreases the longer it
takes to get it to the developer.
1 week: no value
1 hour: small value
1 minute: large value
1 second: Borat value (for make glory!)

28. 28
And software development happens everywhere: at the desk, at home,
at the coffee shop, on the beach
And on all kinds of devices: desktops, laptops, tablets, phones
Tooling must work across all dimensions: the “cloud” to the rescue. Offload
the expensive tasks to remote clusters of powerful computers.

29. 3. Intelligent Developer Platform

30. Introducing AIDE: [A]n [I]DE that [D]oes [E]verything
Building this product is what we’ll be doing the next 1-2 years
30

31. Remember all the things we ask
Software Developers to keep track of?
A plethora of languages, platforms, frameworks, and tasks
31

32. The Product Vision:
Provide software developers automatic and
timely metrics, data, and information about
all of the things they care about.
32

33. 33
Some examples: automatic API doc lookup
(IntelliJ Idea)

34. 34
Some examples: UI hot-reload across device sizes
(Android Studio)

35. 35
Some examples: JVM console
(Eclipse)

36. 36
Some examples: Code Review Status and Feed
(Review Board)

37. 37
Some examples: Continuous Delivery Pipeline
(LinkedIn)

38. The Long-Term Target Audience:
Amateur software developers
38

39. 39
Hopscotch (https://www.gethopscotch.com) -- Software development for kids
Simple, intuitive, automatic, and continuous feedback
Make a change and see what changed, repeat.

40. That’s the goal: a complete software
development platform so simple my
kids can use it.
