• Javascript and SQL were the main tech issues
• Some significant number of bugs related with
meeting expectations with business

• Start teaching Javascript and Advanced SQL in
Ramp up and it will solve all our
problems...right?

#1 Using User Stories instead of features
Context is
everything, create a user
story.
• Improves communication
• Helps to learn the stakeholders “language”
• Capture the reason why we’re delivering something.

By understanding the
users, developers will
start thinking
differently

#2 Defining what’s Ready and what’s Done
• Is the definition of READY met for 70% of the user
stories of next sprint?
– should follow the INVEST principles
– Acceptance criteria has been agreed with the customer
– You have representative sample data
• Have you met the definition of DONE for all user
stories delivered in the Sprint?
– Test each user story against the acceptance criteria
– and other tests defined in the test plan
– may also include conducting automated or manual code reviews over a part of
the code.

#3 Doing Usability Testing
Why is so important developers participation in the
demos?
Usability tests start during the first Demo
• 1st reactions are the most genuine
• Usually there’s Feedback...tons of it
• You don’t need extra budget to this
Disclaimer: this doesn’t substitute user experience tests during the project, it’s another
activity to reach the goal of great apps.

stories

stories
• Setup an environment with realistic sample data

really need you to deliver
Stakeholders must test it!
