Doherty Threshold is a UX principle stating that systems responding in under 400 milliseconds can improve user productivity and satisfaction by maintaining a smooth, uninterrupted workflow.
History of the Doherty Threshold
The Doherty Threshold is a concept from the field of Human-Computer Interaction (HCI). It was introduced by two researchers, Walter J. Doherty and Ahrvind J. Thadani, in the early 1980s, specifically in their article published in the IBM Systems Journal in 1982.
Advantages of the Doherty Threshold
1. Increases Productivity
Users can work faster because they are not interrupted by system delays.
2. Improves User Satisfaction
Fast responses make the experience feel more responsive and enjoyable.
3. Maintains Focus and Flow
Response times under 400 ms help users stay focused without losing attention.
4. Improves Retention
Fast applications or websites are more likely to be preferred and reused by users.
Disadvantages of the Doherty Threshold
1. Not Always Realistic
In complex systems (such as data-heavy applications), it can be difficult to maintain response times below 400 ms.
2. Ignores Visual or Emotional Aspects
Focusing solely on speed may sacrifice aesthetic elements or the emotional user experience.
3. Does Not Consider Feedback Quality
Sometimes a slight delay with visual feedback is better than an instant response without confirmation.
4. Too Technical for All Interaction Types
Not all interactions require ultra-fast responses for example, in learning or exploratory processes.
Example of Doherty Threshold in User Experience (UX)
Mobile Applications: Fast Transitions
In e-commerce apps like Tokopedia or Shopee, when a user taps on a product, the product detail page appears in under 400 milliseconds.

Conclusion
The Doherty Threshold emphasizes that systems responding in under 400 milliseconds can enhance user focus, satisfaction, and efficiency. This makes it highly relevant for modern interactive applications, as UX is not only about visual design but also about speed and responsiveness.
