Brewing The agile way
A story about beer development and tasting
A story about product development and testing
Brewing a prototype
You might not need to have a big infrastructure to test the business value of your idea
#2
Prototype #2 and evolution
Feedback Improvement
Lacking “nose” Reducing boiling time of hops
Strange sweetness Use different dry hops
To little carbonation Increasing bottle sugar
Lighter taste color than expected Increase the Rye content
• Science behind the recipe• Calculated Bitterness
• Calculated Color
• Calculated Alcohol percentage
• Science behind the brewing• Mashing steps
• Evaporation+purching
• Science behind the water!
Putting the craft in to craftsmanship
What can testers learn from brewing beer?Features ≠ User Experience
The user’s experience will lead to success or failure
You might not need to have a big infrastructure to test the business value of your idea
Find out if you need to integrate with a big infrastructure from the beginning
New product? Test business assumptions over functional quality
Determine what makes the project a success and test for this first
Beer brewing/Testing is empirical and a craftsmanship that NOT just everybody can do
From repetition and experimentation one gains mastery
Context can change quality expectations
Not all quality attriubutes are equally important in a certain point of time
