From Prototype to Production. Scaling a Kitting Trolley for Lean Success

Customer Challenge

A long‑standing client approached us with a prototype kitting trolley they had developed in‑house. The concept was solid and functional, but it wasn’t ready for production. They needed multiple units built to a consistent specification, with improved durability, repeatability, and ergonomic performance.

Their goal was clear: replicate the design while enhancing build quality, ensuring the trolley could withstand daily use in a high‑volume, Lean manufacturing environment where reliability, flow, and standardisation are essential.

This challenge is common in modern Lean manufacturing settings. Teams often create one‑off prototypes that work well for testing, but scaling them into robust, repeatable, production‑ready equipment requires deeper engineering, stronger materials, and a modular approach that supports continuous improvement.

Our Approach

We began by reverse‑engineering the prototype, analysing every dimension, load requirement, and functional detail. Understanding the operator workflow was key — how the trolley moved, how components were accessed, and how the design supported (or hindered) material flow.

Using our modular tube‑and‑joint system, we rebuilt the trolley with precision. This approach allowed us to maintain the original intent while introducing subtle but meaningful improvements in:

• Ergonomics — optimised handle height, smoother movement, safer access
• Material handling efficiency — better tote positioning, improved stability
• Lean workflow integration — clearer visual organisation, reduced motion waste
• Durability — stronger joints, reinforced frames, long‑life components

The modular nature of the system also ensured future adaptability — a key advantage for any continuous improvement environment.

The Result

We delivered a batch of high‑quality kitting trolleys that not only matched the original design intent but significantly improved finish, functionality, and long‑term durability.

The new trolleys integrate seamlessly into the client’s Lean workflow, supporting:

• Faster replenishment cycles
• Safer, more ergonomic handling
• Consistent performance across all units
• Reduced variation and improved standardisation

The client now has a scalable, repeatable solution that aligns with their Lean manufacturing principles, enhances workplace efficiency, and supports ongoing process optimisation.

Why It Worked

This project succeeded because it combined Lean thinking with modular engineering:

• A clear prototype to build from
• Collaborative refinement of design
• Modular construction for repeatability and adaptability
• Deep understanding of Lean principles, ergonomics, and workplace demands

By transforming a functional prototype into a production‑ready, scalable solution, we helped the client strengthen their material‑handling process, reduce waste, and support long‑term operational excellence.
