How to take better design decisions?
“Just like computers, human brains have a limited amount of processing power. When the amount of information coming in exceeds our ability to handle it, our performance suffers.”
When a design requires user to spend more time on thinking for just a simple text entry, user will often make mistake costing an organization time & money. If you make people think you make them unhappy, User want to know what they should do immediately, more you make a user to think, the more likely they are going to get the job done elsewhere.
Availability of Information
Designer should always base their decision on user need, it’s advised to work closely with the user, critical design decisions shouldn’t be based only on availability heuristic, it depends on number of factors which includes presenting essential information when it’s required by user in a simpler & informed way.
You can’t prevent all the small problems at times, rather a designer goal should be focus on fixing hidden problems which later mushrooms into large problems, problems are not enemy but hidden problems are, down the road when designing it’s important to be active problem seeker, best way to find hidden problem is to focus on usage analysis of an application, how user process and operate a system can reveal many hidden problems.
As a human being we are inherently biased, recognizing bias in design is necessity to ensure it doesn’t negatively impact our product designers can use pre-mortem technique to find threats not previously considered, focusing on single point of problem limits our ability to plan and design for future.
User research & Case studies
Identify potential design challenges, and seek case studies of what works well for customers in the market, being over confident about a decision isn’t going to help you take a better decision.
