Continuous DeliveryGetting value to the business.
Fast.Often.
Continuous Delivery: everyone wants it
5
But Continuous Delivery is impossible without Continuous Quality
Quality must be built in to the process
So how do you deliver?
Examples
Stories
Features
Capabilities
Goals
Acceptance Criteria
“We are going to build an online classifieds website”
Successful projects start with a shared vision
You define goals to achieve your vision
“Let’s increase advertising revenue by letting sellers post their classified ads
“Let’s get more sales for our advertisers by making the ads easier to find online.”
Goals that will deliver business value
Features help deliver these goals
“Let’s get more sales for our advertisers by making the ads easier to find online.”
Notify potential buyers about new itemsIn order to increase sales of advertised articlesAs a sellerI want previous buyers to know about new items that they might be interested in buying
Search for online adsIn order to increase sales of advertised articlesAs a sellerI want buyers to be able to easily find ads for articles they want to buy
We use examples and stories to explore the features
“Searching by category”
Search for online ads
“Searching by keyword and category”
“Searching by keyword and location”
“Filter ads by price”
We use examples and stories to explore the features
Searching by keyword and location
Search for online ads
Given Sally wants to buy a puppy for her son
When she looks for ads in the ‘Pets and Animals’ category containing
the word ‘puppy’ in New South Wales
Then she should obtain a list of ads for puppies in New South Wales.
Acceptance Criteria illustrate and validate the stories
We automate the acceptance criteria
Scenario: Searching by keyword and location
Given Sally wants to buy a puppy for her son When she looks for ads in the ‘Pets and Animals’ category containing the word ‘puppy’ in New South WalesThen she should obtain a list of ads for puppies in New South Wales.
search_by_keyword_and_location.story
And we implement the acceptance criteria
search_by_keyword_and_location.story
Scenario: Searching by keyword and location
Given Sally wants to buy a puppy for her son When she looks for ads in the ‘Pets and Animals’ category containing the word ‘puppy’ in New South WalesThen she should obtain a list of ads for puppies in New South Wales.
We can now execute our automated acceptance tests
“Searching by keyword and location” is now a pending test
...and implement the application code for that feature
When it is implemented, it will be displayed as a passing test
...and implement the application code for that feature
And the corresponding feature is now partially completed
What’s so important about automating the Acceptance Criteria?
So why automate your acceptance criteria?
They define your goals
They keep you on track
So why automate your acceptance criteria?
They provide better visibility
So why automate your acceptance criteria?
They allow faster release cycles
So why automate your acceptance criteria?
Reduce Risk
So why automate your acceptance criteria?
Reduce Costs
So why automate your acceptance criteria?
Jenkins - it’s how we automate stuff, boss.

So how do you deliver?
Rigorous testing and reporting gives us confidence in our product...
So how do you deliver?
And a Jenkins build pipeline makes automated delivery possible.
