  13. 13. We can go live with this bug if you want to, or we could delay and investigate it further I mean, they wouldn’t be ASKING if it wasn’t ok… We can go live with this bug if you want to, or we could delay and investigate it further We can go live with this bug if you want to, or we could delay and investigate it further Yes - I really want that!
  14. 14. Things we believe as Testers This feature is going to be a success, that’s why I chose it! I’m attached to this feature because I chose it, I may not see its flaws This version is much better Is v48 REALLY good enough or is just better than v47? I’ve tested this many times before and its never broken - this is low risk The risk is only managed if your regression testing is effective
  15. 15. Things others believe on our behalf We are experts in our field, lets stick with what we know We’re so confident in our product, we’re not going to diversify I know you’ve been testing, but I’m going to need a test plan I want to see something that is familiar to me
  16. 16. Be careful what you wish for…
  17. 17. Effects of Passive Involvement What happens if you have increased involvement with a chance interaction?
  18. 18. How about now? How do you rate your chances of winning? And how about now?

  22. 22. mistake https://what-buddha-said.net/gallery/index.php/Dhamma-illustrations/cone_of_uncertainty
  23. 23. Real Life Applications… Cone of uncertainty – on long slow burning projects or features we grow in confidence as we progress along a curve…so we may not listen to a fresh set of eyes that sees something new
  24. 24. Effects of Response Familiarity What happens if you practice, or have experience with a scenario, regardless of whether the outcome is influenced by the interaction?
  25. 25. High Involvement – I’ll show you how to do it Low Involvement – here’s some instructions High Familiarity – have a quick go whilst the machine is turned off Low Familiarity – let’s get started
  26. 26. What Have we Learned? If I FEEL like I’m affecting the outcome, I will be confident in my ability to get it right
  27. 27. Things we believe as Testers If I feel like I understand the feature and I’m seeing the results I expect, I will feel confident in it Are my tests ACTUALLY making any difference? This has all gone so well – our customers are going to love this… I am implying a correlation between the development process and the success of the product Our focus group wasn’t all that positive, but we’ve done this type of feature before – they’ll love it once it goes live I am ignoring evidence contrary to what I want to believe
  28. 28. What CAN I Control?

  31. 31. How to spot a peach tree Don’t be fooled by being given a choice – be careful what you wish for… Challenge your own thinking – think about WHY you are choosing something Listen to new voices - it’s never too late to be wrong Active Involvement – make sure you’re actually adding value
