# App Design Fundamentals

Design is the foundation of every successful application.\
Before building applications on ONEWEB, it is important to understand the **fundamental principles of app design** that guide decisions throughout the application lifecycle.

This section introduces the core design fundamentals that help ensure your application is **focused, usable, and scalable**.

***

#### Define the Purpose of Your App

Every application should start with a **clear purpose**.

Defining the purpose helps you:

* Understand what problem the application is solving
* Keep design decisions aligned with business goals
* Avoid unnecessary features that add complexity

A well‑defined purpose serves as a reference point throughout the design and development process.

***

#### Plan the Application Scope

Once the purpose is clear, the next step is to **plan the scope of the application**.

Effective planning includes:

* Identifying core features and capabilities
* Defining what is included in the first version of the app
* Understanding who the target users are and how they will use the application

A clear plan helps control scope, reduce rework, and support incremental growth of the application.

***

#### Understand Users and Context

Good application design is driven by **user needs and context**.

Before designing screens and flows, consider:

* Who will use the application
* What tasks users need to complete
* In which environment the application will be used (desktop, mobile, internal, external)

Understanding users helps ensure that the application is intuitive and relevant.

***

#### Design the Application Structure

Before focusing on visuals, design the **structure and flow** of the application.

This includes:

* Defining main modules and navigation
* Identifying key screens and interactions
* Mapping how users move through the application

This structural design forms the backbone of the application and ensures a logical and consistent user experience.

***

#### Create Wireframes

Wireframes represent the **visual and interaction blueprint** of the application.

Wireframes help you:

* Visualize page layouts and screen hierarchy
* Define how information and actions are presented
* Validate application flow before implementation

By using wireframes early, you can refine the design efficiently before moving into detailed configuration and development.

***

#### Why App Design Fundamentals Matter

Applying these design fundamentals helps you:

* Build applications that are easier to use and maintain
* Reduce redesign and rework later in the lifecycle
* Create a strong foundation for implementation on ONEWEB

With these fundamentals in place, you are ready to move from design concepts to building your first application.
