Engineering terms, explained plainly

Plain definitions of engineering ownership, software rescue and legacy modernisation, with practical examples and links to further reading.

What is engineering ownership?

Engineering ownership is an agreement about who is responsible for the behaviour and care of a software system. It should make decisions and operating duties clear while keeping the company in control.

What is legacy modernisation?

Legacy modernisation changes an existing system so the business can keep using it with less risk or friction. The useful starting point is a constraint to remove, rather than the age of the technology.

What is a software rescue engagement?

A software rescue engagement is a bounded investigation and recovery effort for a system or project that is no longer making useful progress. It starts with evidence about the failure, not a predetermined rewrite.
