The Opportunity

When expertise walks out the door

Preserving knowledge for the future

Maverick Partners were brought in to help a global packaging manufacturer solve a growing operational problem.

Critical engineering knowledge existed across manuals, service reports but, most importantly, in the experience of long-serving engineers.

As those engineers retired, decades of practical knowledge risked disappearing with them.

The Opportunity

Discovery

Identifying The Challenge

A short discovery phase quickly revealed that the challenge wasn't simply documenting information.

Engineers already had access to manuals and technical documentation, they just couldn't retrieve the right knowledge quickly enough when production lines were under pressure.

They needed help from someone with the right knowledge

Every Organisation Has That 'Special' Team Member

• The engineer who's been there for decades.

• The one everyone asks when a machine fails.

• The one who knows the fixes that never made it into the manual.

• When they retire... that knowledge retires with him.

For this organisation that team member was Dave

Harnessing the power of 'Dave'

Our Approach

We would attempt this by developing an . The product would transform fragmented documentationinto a giving engineers instant access to trusted answers drawn entirely from their own expertise and documentation.

What began as an internal solution to preserve knowledge soon revealed a much bigger opportunity.

Our team hypothesised that by harnessing what made Dave such a valued team member, we would be able to help bridge the gap between years of expert knowledge and the next generation of engineers.

The Opportunity

My Contribution

I joined the project during the proof of concept phase, where I was responsible for designing the early UX and user interface.

Working closely with a developer, we transformed an emerging concept into a functional prototype, creating a product that could be tested in real manufacturing environments rather than simply presented as an idea.

The proof of concept wasn't designed to validate user flows—it was built to answer a much bigger question: could this approach genuinely change the way engineers worked? The success of that prototype established the foundations for what would later evolve into Expert Advisor.

The Opportunity

Why should an engineer trust AI?

Building The Platform Was Only Part Of The Challenge.

For engineers to rely on Expert Advisor during critical moments, the experience needed to feel trustworthy from the very first interaction.

Trusted Knowledge

Every response was generated from company documentation not the open internet.

Knowledge That Grows

Knowledge captured through notes, photos, voice recordings and videos, allowing the platform to improve over time.

Every design decision focused on reducing uncertainty, reinforcing confidence and fitting naturally into existing ways of working.

V.1

Building The MVP

The proof of concept focused on answering a single question:

Could this approach genuinely improve the way engineers accessed knowledge under pressure?

Instead of building a feature-rich platform, we focused on delivering a complete product centred on the core user journey. This would allow us to validate the concept in real manufacturing environments before expanding the platform into a broader commercial offering.

Dashboard

Engineers could immediately see recent activity, documentation and key actions from any device.

Built for the Factory Floor

Responsive layouts were designed around the environments engineers actually worked in.

Tablet and mobile breakpoints were prioritised, allowing Expert Advisor to be used directly on the factory floor without sacrificing clarity or speed.

Step 1 explains locking the pneumatic supply valve with a padlock to prevent unauthorized activation, accompanied by images of a locked valve switch, a machine AR mockup, and a schematic diagram. Step 2 advises cutting off product loading to avoid contamination during spills. There are options to edit, view related training titles, access a full list, and give feedback with thumbs up or down. A chat box and navigation controls are also visible.

Validating The Idea

The proof of concept was tested in live manufacturing environments, where engineers relied on it during real maintenance and troubleshooting tasks.

Early results demonstrated that the approach wasn't just technically viable, it delivered measurable improvements to the way teams worked.

Beyond the numbers, the project revealed something equally important. Knowledge that had previously existed only in the experience of senior engineers was beginning to be captured, shared and reused across the wider organisation.

The proof of concept had validated the idea, opening the door for the concept to evolve.

The Opportunity

The proof of concept validated more than the technology, it validated the opportunity.

The success of the proof of concept revealed an opportunity far beyond a single organisation. To bring Expert Advisor to a wider market, Pelletech was established as a new venture dedicated to transforming the concept into a commercial platform for manufacturers.

This marked a significant shift in the project's priorities.

The product needed to grow beyond its original scope, supporting broader workflows while presenting a more confident, market-ready experience. What had proven itself as a practical engineering tool now needed to communicate innovation, reliability and trust before customers had even used it.

Brand development

A New Focus

As the product entered this new phase, my focus shifted towards defining a stronger visual language for the platform.

Working alongside a UX designer who expanded the underlying journeys, I concentrated on refining the interface, growing the component library into a scalable design system and ensuring the product felt both dependable for engineers and compelling to prospective customers.

UI Exploration

Defining The Visual Language

The first release was designed to prove the idea. The next needed to sell it.

Early feedback showed the interface felt functional, but visually conservative, lacking the distinction needed to stand out in demonstrations.

The challenge became evolving the visual language without compromising the clarity and usability that had made the proof of concept successful.

Through a series of visual explorations, colour, typography, depth and interface styling were refined into a more confident identity that felt commercially credible while remaining practical for engineers.

System Insights

Scaling beyond Chat

As the platform matured, visibility became just as important as retrieval.

Dashboard views gave administrators insight into adoption, content quality and query trends, helping organisations understand how knowledge was being used across their sites.

Natural Language Search

Finding Answers Faster

Every interaction was shaped around the reality of the factory floor

Responses were intentionally concise, surfacing the most relevant information first while providing clear references that engineers could quickly verify before taking action.

Rather than adding complexity, the interface stayed focused on helping people solve problems with confidence and get back to work.

Designing For Context

Built for Engineers On The Move

Designing for manufacturing meant designing for context, not just screens.

Rather than treating responsive layouts as a technical requirement, tablet and mobile became the primary experience, ensuring engineers could access trusted information naturally while working on the factory floor.

Brand development

Supporting The Launch

Introducing Expert Advisor To The World

As Expert Advisor moved towards commercial launch, the challenge extended beyond the application itself.

Prospective customers needed to understand the product before they ever used it.

Alongside the product UI, I designed and produced a launch film, a supporting marketing website and printed collateral for trade shows, ensuring every touchpoint reflected the same visual language and communicated the product's value with clarity and confidence.

The Opportunity

Reflection

What interested me most about this project was that it wasn't really about the technology, It was about making expertise accessible. We were never trying to replace experienced engineers, we were trying to ensure their knowledge could continue to help others.

The project reinforced something I value in my work, technology is at its best when it fades into the background, allowing people to focus on what they're actually trying to achieve.
