Why is it important for the layout of an interface to be consistent?

Consistent user interfaces facilitate communication. Use visual consistency to prioritize content, make it navigable, or highlight important bits of it. By using consistency to create a logical structure and to clearly define where users can find what, you'll spare yourself confused and frustrated users.

Why consistency in design is important?

Design consistency improves usability and learnability, especially when similar elements look and function similarly. When consistency is an integral part of your design, people can grasp new contexts quickly without pain or confusion since they know what to expect next with your design.

Why is it important to maintain the consistency of software system interface?

Consistency limits the number of ways actions and operations are represented, ensuring that users do not have to learn new representations for each task. Further, establishing design norms like following platform conventions allow users to complete new tasks without having to learn a whole new toolset.

How does consistency affect GUI?

Increased usability. Because users don't have to learn new ropes to go about, consistency makes it easier for them to navigate and use applications. They know what to expect because they've learnt it somewhere else will find it easier to explore and use the app if the UI designs are consistent.
