Crafting a User-Centric Experience: Task-Based UI vs CRUD
Written on
Chapter 1 Understanding UI Approaches
When you have an API capable of executing numerous functions simultaneously, enhancing it to meet demanding customer needs can be challenging. One effective strategy is to implement a Task-based UI. This design method prioritizes user tasks over the raw data they interact with, aligning seamlessly with the Command Query Responsibility Segregation (CQRS) model. In this framework, commands that modify state are distinctly separated from queries that retrieve state.
Section 1.1 CRUD UI Explained
In a conventional CRUD (Create, Read, Update, Delete) interface, users engage directly with data. For instance, if someone wishes to update their mailing address, they would typically go to a "User Details" page, locate the "Address" section, make the necessary changes, and click "Save." This process triggers an UpdateUser command sent to the backend.
Section 1.2 Transitioning to Task-Based UI
In contrast, a Task-based UI allows users to execute tasks that mirror their intentions. For example, to update their mailing address, a user might select a "Change Mailing Address" button. This action opens a form prompting them for the new address. Upon submission, the application sends a ChangeMailingAddress command to the backend.

This video delves into breaking down CRUD processes to adopt a task-based approach, emphasizing how this shift can enhance user experience.
Subsection 1.2.1 Code Simplification
To illustrate, consider pseudocode: in a CRUD UI, the updateUser function must determine the specific changes made. Conversely, in a Task-based UI, the changeMailingAddress function is clear about the user’s intent. This clarity simplifies code, making it more manageable and less error-prone.
For instance, if you wish to send a confirmation email after a user updates their address, you can incorporate this directly into the changeMailingAddress function. In a CRUD UI, this logic would complicate the updateUser function, leading to increased maintenance challenges.
Chapter 2 Evaluating Task-Based UI
While a task-based UI offers many advantages, it's not a one-size-fits-all solution. Its effectiveness depends on the context. For applications needing to support diverse operations within a flexible data model, a traditional CRUD API might be more suitable.
On the other hand, if your API is designed primarily for a specific set of tasks, a task-based UI can significantly improve usability and maintainability by enforcing a clear separation of concerns.
