Printed Guides → Offline Mobile Platform for 20,000 Employees
Transforming 72 printed operational guides into an offline-first mobile experience used daily across a global organization, sole designer, end-to-end ownership, delivered in 8 months.
Transforming printed operational guides into a mobile experience
A large global organization relied on 72 printed operational guides containing technical procedures used daily by employees and supervisors in demanding environments, guides that were difficult to navigate, expensive to maintain, and impractical to carry and use on-site.
The objective was to transform this documentation into a mobile application. Analyzing the 72 guides revealed a consistent 14-section structure across all operational areas, which became the foundation of the app's information architecture, and a deliberate choice to preserve familiarity and minimize the learning curve for users with limited digital experience.
Sole Product Designer responsible for the end-to-end product design. I collaborated with the Product Owner, Project Manager, engineering team, system architect, and operational stakeholders, aligning these groups around an MVP scope that was technically feasible while still meeting user needs, which required negotiating trade-offs and defining what would ship in the first release versus later iterations.
My responsibilities included:
- Defining the product experience strategy and MVP scope in collaboration with the PO and PM
- Designing the information architecture and navigation system based on the existing guide structure
- Running usability testing with real employees using low-fidelity wireframes to validate assumptions
- Designing the final interface and accessibility approach for challenging conditions
- Working closely with the system architect to ensure reliable offline performance
With limited time for primary research, discovery was structured around a close analysis of the 72 operational guides and stakeholder input from the PM and operational team. Usability testing on interactive prototypes with real employees then validated those assumptions, and surfaced the need for more explicit language labeling across sections, which shaped the final content structure.
Mapping the 72 operational guides revealed a consistent 14-section structure, which became the IA backbone
Biweekly sessions with the PM, engineers, and operational leads shaped MVP priorities and technical constraints
Low-fidelity prototypes tested with real employees surfaced key friction points and validated the navigation model
Offline-first usage in environments with limited connectivity
Challenging physical conditions affecting device interaction
Limited familiarity with mobile interfaces among users
Large volumes of structured technical documentation
Navigation mirroring the structure of the original printed guides, with a component system designed for dense technical documentation.
Choices that shaped the product
Advanced search was not feasible in the first release due to system limitations, a constraint I identified early and brought to the PO to align expectations. Rather than treating this as a blocker, I designed a navigation structure based on the existing 14-section guide architecture, allowing users to locate procedures intuitively without relying on search. This also reduced friction for users with limited digital familiarity.
The original procedural content was dense and difficult to read on mobile devices. I reorganized the documentation using hierarchical structures and modular components to improve readability and enable quick scanning during task execution.
Images and file sizes were carefully managed to ensure reliable offline performance, while still supporting comprehension when visual references were necessary.
Many devices were configured in English by default. To prevent friction, language selection was placed prominently so users could quickly access content in their preferred language.
Delivered on time. Used every day.
The application was delivered in eight months by a single designer and deployed to approximately 20,000 employees, becoming the standard operational reference tool across the organization.
Usability testing with real employees on an interactive prototype showed a 15% reduction in time to locate procedures compared to the printed guides, a meaningful gain in environments where speed and accuracy directly affect operational safety. Replacing the printed manuals also eliminated a significant ongoing cost for the organization.
