Merck Animal Health wanted to redesign their internal revenue calculator used by veterinary clinics. The goal: help clinic staff easily estimate the potential revenue boost from switching to Bravecto, a long-lasting flea and tick treatment.

Challenges
Tablet Usability: The original tool was hard to use on iPads — small text, cluttered layout, poor touch targets.
Confusing Inputs: Users didn’t know what to enter or why.
Unclear Output: Revenue projections weren’t visual or actionable.
Drop-offs: Users often abandoned the tool halfway through.
My Approach
Discovery Phase
Client Brief Review: Understood Merck’s business goal — help reps and clinics clearly see the value of Bravecto.
Stakeholder Interviews: Collaborated with reps and marketing teams to define success.
User Interviews: Talked to 5 vet techs and 3 clinic managers using iPads daily. Key feedback: “It’s too time-consuming,” “I want to show results quickly,” “Make it easy to share.”
Design and Development
Tablet-First Design: Every layout, button, and interaction was built specifically for iPads — large touch areas, readable text, and a clear tap flow.
Guided Flow: Broke the tool into bite-sized steps to reduce overwhelm and mimic a real conversation.
Visual Feedback: Added charts and bar visuals to show revenue impact instantly.
Smart Defaults: Used average values to help users get started faster.
CTA: Ended with clear next steps — downloadable results and a button to contact a Merck rep.
Testing and Iteration
Usability Testing: Tested on tablets with internal users and reps. Tweaked inputs and spacing based on real-time feedback.
Quick Iterations: Improved label clarity, removed friction points, and adjusted layout for better thumb reach and scroll behavior.
Style Guide: Created a clean, tablet-optimized UI system with a focus on touch accessibility and fast reading in clinic environments.

Conclusion
Redesigning the Bravecto calculator with tablet use in mind made it faster, easier, and way more effective. By simplifying inputs, adding visual impact, and optimizing the experience for iPads, we helped reps better engage clinics — and made the business case for Bravecto crystal clear.
