What happened
The Boeing 777 was the first airliner designed entirely digitally. Airlines joined the design teams early in the programme.
The aircraft entered service in 1995 with ETOPS approval from day one.
What was found
Accounts of the programme connect two choices: involving the people who would operate the aircraft early, and working from a shared digital model of the design.
Together these reduced late surprises. Questions that might otherwise have surfaced during integration or entry into service were raised while the design could still change cheaply.
Engineering lesson
Late surprises are usually requirements that were never captured or interfaces that were never shared. Bringing operators in early widens the set of requirements that are known before design hardens.
A single shared model gives every team the same version of the truth, so disagreements show up as visible conflicts rather than as parts that do not fit.
The practice this points to
Involve the stakeholders who will operate and maintain the system while requirements are still being formed.
Work from a shared, authoritative model of requirements and design, so every team sees the same current state.
Where Kelvora fits
Kelvora is a requirements and assurance platform that gives engineering teams and stakeholders one shared, current view of requirements and their links to design and evidence. It is intended to surface conflicts and gaps early, while engineers decide how to resolve them.
