Two weeks before I broke my spectacle that was bought just six months back. Now needless to say, I have to buy a new spectacle. So I went into a spectacle store. On entering the store I saw four to five sales executives with a warm smile (Yeah! Two of them were good looking girls ;)) .I was totally confused whom should I approach first. You have to believe me that I did not go to the cute looking girls, instead decided to Go to Gemba as one among them was wearing spectacle. I thought he (yea, unfortunately it is he😦 ) would be the correct person to help me out in selecting the better spectacle.
I approached him, and asked for nice frames that would be within my budget and yea,good looking too. He helped me with many of the frames displayed. He suggested with few frames that would make me to look even smarter😉. I tried out quite a little and focused on the mirror to know if I am looking smarter. I shortlisted three frames but still not able to decide on which one to select. With the confusion I went and took a seat, to get my eye power tested.
I had my previously tested power details noted, so I gave him the card that has my eye power details. The salesperson asked for my older spectacle as well to cross verify the power in it. So I handed over both the card and broken spectacle, after measuring the power, I found there was a 5 degree difference between the power details in the card and the spectacle. I remember the last spectacle was ordered with the power prescribed in that card. So I asked the salesperson why there is a difference, he said that could be a manufacturing defect, a manual or machine fault. Then I asked is the 5 degree difference a major concern, though I did not find any issues with that lens. He said it is not a major issue and up to 10 degree will not have any visual difference.
I just wondered what if people go with this mindset and then design, develop, test, maintain and use a machine that is to be used to destroy cancer cells or a MRI Scan machine, where precision is very important. So it is
Good to bring prior knowledge and experience, but not the mind-set across different projects.
Needless to say this time I checked the power again in the new spectacle at the time of delivery, I am a tester and I test every thing.
Back to the story, I was still wearing one of the new frames I shortlisted, at the time of the discussion about power difference, I realized that the frame is not so comfortable .I felt some irritation near my ears and nose. That’s when I realized my focus on how it looks to me, made me to ignore many other important factors. When I defocused from one factor, I was able to feel\realize many other missed factors. And I didn’t even focus on comfort, just defocusing from one factor automatically helped to realize other factors. Now I focused on the comfort factor and ended in selecting a frame better frame. So before starting of testing list down the factors prioritized like Functionality, Usability, Testability, Maintainability, Reliability, Compatibility, Scalability etc., then start focusing on them one by one based on priority.
Defocusing is as important as focusing.
But was this the better frame and will it be free from problems? I don’t know because
Problems unfold over time in ways that are often not predictable.
Here is one great example I read recently how any system cannot be defined with a boundary and how problem unfold that are often not predictable. When Denver airport was built, it was claimed that the airport would never close, even for a snowstorm. The advanced technology would permit flights to take off n land even in adverse weather. When the first big snowstorm hit, every flight got cancelled. Why? Pilots lived in mountains nearby and they could not get to airport in storm.
Happy Focusing and Defocusing!
