In the world of web design there are many web designers who, once they design something, have it set in stone. They don’t like it when it changes or deviates from the original design that they worked on. This is understandable when designers have poured a lot of effort/time to get a mixture of creativity, UX - UI patterns and branding on the design. The same with developers. They spend a long time making the solution and suddenly changes need to be made to the page They've been through the designs with the designer - so why is it changing?
So when someone says I want to test that verses this idea, they feel like it’s putting down their design skills and knowledge. This isn’t the case. This is normally another person seeing something from a different angle.
Learn / Update Your Skills
Testing also is something a designer/developer should embrace as it’s an avenue for them to prove their understandings and reshape what they know with facts and figures. A designer/developer with the open minded approach of 'test it - because right or wrong, I’ll learn' is more valuable to a company than one who says 'I’m the expert and only my view matters'.
At Kraken, We are fortunate to work with a very open minded and talented designer (Hannah) and developer (Sam). Hannah works with Sam on ideas and concepts to help improve people’s site goals. This could be working on getting more sign ups or getting more people to the checkout. What we want is constant understanding of what it is we do, and to further that knowledge that makes us masters in our areas of expertise.
Testing a site and using the data from those tests will improve not only the website but also improve the designers and developers ideas of what works where. Adding lots of small ideas to improve the library of knowledge you bring to the table for each and every customer.
What To Take Away - TLDR
So from this read take away the ability to be flexible in thinking about solutions. What worked on one site may not work on another due to other factors - and embrace that sharpening of your tools and knowledge through testing.
