Our name

The Royal Navy use the OPDEF (operational defect) signal as a powerful tool: it flags a critical defect that directly impacts a unit’s ability to operate. It’s precise, standardised, and instantly understood — everyone involved knows how to interpret it and act fast.

One sharp, clear line summarises the impact, cutting through the noise to drive swift, decisive action. This isn’t just about defects; it’s about understanding and addressing real operational impact. At Line 5, we bring this same military-grade discipline to help organisations with physical assets focus on value-driven activities and get results.
