In crafting exceptional user experiences, understanding what prompts users to take action is as crucial as understanding their motivations and abilities. The Fogg Behaviour Model emphasises the importance of triggers in initiating desired behaviours. This article looks into the role of triggers in UX design, exploring their types and offering guidelines on creating effective prompts that drive user behaviour. This is the 4th article in the Fogg’s behaviour series. If you would like to view previous articles click here.
The Role of Triggers in the Fogg Behaviour Model
In the Fogg Behaviour Model (FBM), a behaviour occurs when Motivation, Ability, and Trigger converge simultaneously. While motivation and ability determine a user’s likeliness to act, triggers are the prompts that catalyse this action. Without an appropriate trigger, even highly motivated users with the ability to complete a task may fail to take the desired action.
Types of Triggers
Triggers can be broadly categorised into two types: external and internal.
External Triggers
Explicit Triggers: These are direct prompts like notifications, alerts, or pop-ups that urge users to take immediate action. For example, a push notification from a fitness app reminding users to log their workout.
**Embedded Triggers: **These are prompts integrated into the user experience, such as call-to-action buttons or in-app messages. For instance, a "Buy Now" button on an e-commerce site.
Implicit Triggers: These are subtle cues embedded in the environment or design, like visual cues or changes in interface that indicate an action is needed. An example would be a blinking cursor in a search bar.
Internal Triggers
Emotional Triggers: These are internal states or emotions that prompt action, such as boredom leading a user to open a social media app or anxiety prompting the use of a meditation app.
Routine Triggers: These are habitual cues that are part of the user's routine, like checking email first thing in the morning.
Crafting Effective Triggers
Creating effective triggers requires a balance of timing, relevance, and clarity. Here are some guidelines for designing triggers that effectively prompt user behaviour:
Timeliness
Ensure that triggers occur at moments when users are likely to act. For instance, sending a reminder to complete a task at a time when users typically engage with the app. Utilise user behaviour data to personalise trigger timing, such as sending notifications based on user activity patterns. ** Relevance**
Triggers should be contextually relevant to the user’s current state or activity. Avoid generic prompts and tailor messages to individual user needs. For example, a weather app can send an umbrella reminder on a rainy day, making the prompt relevant to the user’s immediate environment.
Clarity
Ensure that triggers are clear and concise, leaving no ambiguity about the desired action. Use straightforward language and avoid jargon. A clear call-to-action, such as “Complete Your Profile” or “Checkout Now,” helps users understand exactly what is expected of them.
Value Proposition
Highlight the benefit of taking the action prompted by the trigger. Users are more likely to respond to prompts that offer clear value or reward. For example, a prompt that says “Earn 50 points by completing this survey” communicates a tangible benefit to the user.
Effective triggers are essential for driving user behaviour and ensuring that desired actions are taken. By understanding the types of triggers and applying principles of timeliness, relevance, clarity, and value, UX designers can craft prompts that seamlessly guide users through their interactions. In our next article, we will analyse common UX design patterns through the lens of the Fogg Behaviour Model, showcasing how motivation, ability, and triggers align to create compelling user experiences.
