Absolutely! Having a mobile-friendly website is more important than ever! We put forth a lot of effort to ensure that your website looks good on all online devices.
We follow an Agile Development Process (Backlog - Bootstrap - Wave 0 - Wave N) focused on continuously delivering useful software in increments. It follows a cooperative approach where the team regularly iterates to improve efficiency and ensure the alignment of business goals. The goals and requirements are reviewed by the end of each sprint to deliver the most value in the next stage.

This is a scrum-based methodology (Plan > Execute > Test > Review). It allows us to deliver new features in shorter time frames responding quickly to change, accelerating your product's development process.

To deliver a world-class digital product, we recommended following the Product Design Process:

1. Conduct user research - Being the UX designer's responsibility, the main goal of the user research step is to gather evidence that will support the decisions taken henceforth, ensuring that no decision is made based on vague assumptions. In this step, we identify the main aspects of the business model and user needs.

2. Create user personas - Part of the ideation step, creating the user person is the core of the creative process and it is where the concept of the product is formulated based on the user's needs and the business model (both identified in the Research phase). Here, the UX designer, the product designer, and the product owner should work closely together. Then, the ideal user experience is mapped by describing each user's action. In this step, various user scenarios are written and validated. Overall, it provides a global user experience vision, ensuring its consistency and fluidity. Moreover, the user journey also serves as a base to establish the product requirements.

3. Plan the information architecture, design flows, and wireframes - In this step, the product designer focuses on creating a physical representation of the concept that has been defined up to this point. They will create a Style Guide (colour palette, fonts, image style, input fields, buttons, and so on). Then they proceed to the Graphic User Interface (GUI) Design, which executes the end-looking screens by applying the Style Guide to the Wireframes. This step provides stakeholders with the final aspect of the product's screens in order to obtain approval before moving to the implementation.

4. Create the prototype - Here, a click-through Prototype is developed to be accessible online and shareable with other devices and users through a link and password. The Prototype step allows the navigation from screen-to-screen, facilitating the feedback intake either from stakeholders or potential users and investors.

5. Finalize with usability tests.
