Some products are easy to understand. But they are still difficult to use. This is where usability becomes important.
Understanding Is Not the Same as Usability
As explored in issue #08, understandability is about whether customers know what to do. Usability is a different question: can they do it easily?
A customer may understand the product completely and still find it frustrating to operate.
Common Usability Issues That Don't Show Up in Specs

Many usability issues are subtle and rarely appear on specification sheets. But they appear immediately during real use:
- Buttons may require too much force
- Parts may be difficult to assemble
- Adjustments may feel awkward
- Connections may take multiple attempts
- Functions may be technically available but difficult to access
How Customers Describe Usability Friction
Customers often describe these experiences with simple language:
- “It was annoying.”
- “It took too long.”
- “It wasn’t convenient.”
- “It wasn’t worth the effort.”
These reactions can influence overall satisfaction even when the product functions correctly.
What We Observe in Usability Testing
At CommBriX, usability testing looks at the real interaction between product and user. We observe:
- How easily tasks can be completed
- Where users hesitate
- Where users repeat actions
- Where frustration appears
- Which steps feel smooth
- Which steps feel difficult
The Goal: Identify Friction Before Customers Do
The goal is not perfection. The goal is to identify friction before customers do.
Because every unnecessary obstacle creates risk. And every smoother interaction creates confidence.
A product should not only work. It should work comfortably.
Know your product before you source it.
