The Challenge

Create an ecommerce website that effectively communicates the environmental, economic, and comfort benefits of using Firefly. The site needed to address both potential buyers and existing owners, including product instructions and documentation. The interface had to be simple and user-friendly, reflecting the product's philosophy of ease of use, while also delivering a new logo and visual demonstration of how the product works.

The Solution

A modern, responsive, and minimalist UI design that focused on clarity and intuitive navigation. The design process used Hick's Law to refine navigation and reduce decision time, along with clear, visually distinct calls-to-action. We delivered a new logo design following a flat, 2D monochrome direction, and created an animated infographic to visually demonstrate the product's functionality.

Design Principles

The design process focused on creating a user-friendly interface that reflected the product's philosophy of simplicity and ease of use. We implemented several key design principles to achieve this goal:

Modern UI

Modern, responsive, minimalist UI for broad device access and clarity, ensuring all users can easily navigate the site regardless of their device.

Intuitive Navigation

Navigation refined using Hick's Law—reducing choices to minimize decision time and avoid paralysis, making the user journey smooth and straightforward.

Clear CTAs

Visually distinct calls-to-action using imperative wording ("Buy", "More info") to guide users toward key actions and conversions.

Branding

Logo design followed a flat, 2D monochrome direction based on competitive scan of similar products and Danish design principles.

Usability Testing & Improvements

Testing Method

We conducted think-aloud usability tests with potential users to identify issues and areas for improvement in the early design. This revealed two key issues that needed addressing:

Aesthetic Clarity

Early build felt inconsistent and not aligned with the product; users wanted more visuals.

Problem
Solution: Added more placeholder images + an animated infographic

Manual Findability

Manual was hard to discover (nested under sorting).

Problem
Solution: Moved manual to the "About" section for visibility

Estimation & Planning

To ensure accurate project scoping and planning, we implemented the Delphi method with three experts who independently estimated time and costs for:

Design Branding, product research, web design
Development WordPress implementation, integrations
Content Logo, infographics, bilingual manuals
Testing Usability and functional testing
Approach Averaged estimates to reduce bias, added 15% contingency, documented in Excel

Outcomes

Clearer Value Communication

Site structure and CTA placement tie benefits directly to key paths

Improved Content Discoverability

Manual relocation and richer visuals including animated infographic

Brand Foundations

New logo and visual demonstration establishing consistent identity
