QA? Not the way! You can't test quality into a product

Published on

It is a common belief that increasing the amount of testing, hiring more testers or increasing the skill/experience of the existing testers will improve the quality of the software being produced. Testing professionals are held accountable as gate keepers of quality, often given the title “Quality Assurance”, which can imply that others are not responsible for quality. This term also gets used for testing activity rather than the testers themselves. “Have we done QA on that?”.
But the truth is, quality is not really about testing per se, or at least it is not determined by it. The whole testing paradigm is different in Agile because it removes the emphasis from checking and inspecting quality to designing and building in quality, including building the right thing for the customer in the first place, and this is something everyone needs to be involved in, not just testers. In an Agile ecosystem, quality is affected both positively and negatively by many factors in sales and marketing through to product and portfolio management, what the customer actually wants/needs, the mindset of the stakeholders involved, and beyond.
This talk will call out these factors, and explain how rejecting the “QA” concept and taking a fresh outlook on what “Agile testing” actually is can help improve the quality of what is being built. I hope this will enable testers and other folks in development teams to look upstream – and those outside the team to look downstream – at collaborative ways to increase the chances of building high quality software for our customers.

  1. 1. QA? Not the way!
 
 You can’t test quality into a product @neil_killick
  2. 2. What is Quality Assurance (QA)? “…the maintenance of a desired level of quality in a service or product, especially by means of attention to every stage of the process of delivery or production.” ~ Google “…a way of preventing mistakes or defects in manufactured products and avoiding problems when delivering solutions or services to customers… This defect prevention in quality assurance differs subtly from defect detection and rejection in quality control, and has been referred to as a shift left as it focuses on quality earlier in the process.” ~ Wikipedia @neil_killick

  7. 7. Product Development Build the right thing, build the thing right? Yeah right! Projects/PMO “You must get these features/projects done on time! Including all the new stuff!” Revenue and KPI’s “You must deliver $25 million in revenue this year!” Marketing “You must get these features in by May 10th - we promised the market!” Recruitment • “I’m a gun, ninja for hire coder - I don’t need to test my code, that’s what testers are for!” • Hire quickly, hire for skills and experience, meet head count Technical environment/competency • “We don’t have the time/$$ to invest in CD tools - just speed up!” • “We can’t afford that technology!” • “We don’t have budget for training (and it takes you away from your work!)” Mindset • Tolerance for defects • Hand-off mentality (“it’s someone else’s problem!”) @neil_killick
  8. 8. The Manifesto for Shitty Software Development We are uncovering shittier ways of developing software by doing feature death marches and helping others do it. Through this work we have come to value: Getting shit out the door over doing a good job Quantity of features over quality of product Being on schedule over building the right thing Being busy over having time to build quality in That is, while there is value in the items on the right, we value the items on the left more. @neil_killick

  15. 15. Receive and understand requirement Acceptance test - Write failing feature test Code test - Write failing unit test Write code Refactor MY code Integrate my code Refactor THE code supporting the feature Agree all product tests to support feature Ensure all tests pass Agility - Ensure THE code is easy to change, delete and extend Does MY code do what I expect it to do? Does THE code do what the USER expects it to do? @neil_killick
