Just like customers/consumers form perceptions about the company by looking at its office or retail outlet, in the online world, a great looking website/portal/application is the first experience that your customers have with your brand. How they perceive you is likely to be influenced quite significantly by the quality of your UI and the overall experience of your online property.
Users don’t care about what’s lies underneath, but what they actually do and what they see, feel and experience. In other words, it is the quality of the design that affects the business results.
A good design and interface not only the impacts consumers, but can also influence the decision of potential investors.
From a non-designers perspective: a good, well thought-out and executed design is subliminal, yet very powerful. Product User Interface (UI) and User Experience (UX) – regardless of web, mobile, or software – and it’s ease of use is one of the critical factors with respect to its popularity.
