Case Study: T-H Marine Supplies achieves $3.8M in increased production capacity with 15Five

How a Boat Part Manufacturer Turned Employee Feedback into $3.8M in Increased Production Capacity

T-H Marine Supplies, a boat parts manufacturer, was struggling with culture issues, siloed departments, and low employee trust, but had no reliable way to measure engagement or pinpoint the root causes. Before working with 15Five, leaders relied on informal feedback and paper surveys that lacked confidentiality and actionable data.

With 15Five, T-H Marine Supplies launched confidential employee engagement surveys that delivered an 87% response rate and clear insights into trust, shared values, and resource gaps. Acting on the feedback, the company improved team communication and invested in hydraulic lift carts, boosting station capacity by 67% and speeding tasks by 30%; overall, this helped save about $20,000 in labor costs and add $3.8 million in production capacity.
