Forward Deployed Engineering
A delivery discipline for going from an operating problem to a deployed system and measurable outcome.
Proximity is the method
Forward deployed engineering means working where the problem lives. The engineer stays close enough to the operation to observe the constraint directly and shorten the loop between observation and change.
Proximity is not a preference about working style. It is the instrument, because the information the work depends on does not exist anywhere else. Asked to describe their process, people give the version they would give a new starter: the intended path, cleaned of the detours that have become automatic. The detours are the load-bearing part, and they are only recoverable by being present while the work happens and noticing the thing nobody narrated because it did not occur to them that it counted.
Distance also changes what you are told. The first week produces the official account. Later, once it is clear that nobody is being scored, you start hearing which approver is slow, which report nobody reads, and which field everyone fills with a placeholder. None of that is available to a visitor, and all of it is the actual system.
The unit of delivery is an outcome
A deployed feature is not the result. The result is a measurable change in how the operation performs: shorter turnaround, fewer escalations, higher completion, less manual reconciliation, or another operational measure.
Artifacts became the currency because they are countable. A platform, a report, a migration completed on schedule can each be verified by someone who was not present, at a fixed moment, without judgment. Outcomes have none of those properties, which is why delivery structures drift toward the artifact even when everyone in the room wants the outcome.
An outcome that holds needs three constraints. It has to be a change in the operation rather than in the tooling. It has to be named before the work starts rather than selected afterwards from whatever happened to move. And it has to survive the withdrawal of attention, because a number that improves while a project team is in the building and reverts within a quarter measured the project rather than the system.
Build, deploy, stay
Deployment changes the problem. Real use surfaces conditions that no requirements document predicted. The engineer stays through that contact and adapts until the system is owned and operable by the organization.
Some requirements do not exist before deployment, which is a stronger claim than saying they are hard to gather. Volume changes behavior, exceptions arrive at rates nobody predicts, habit outruns policy, and incentives assert themselves in ways no demonstration reproduces. A constraint that only appears in the relationship between a review step's throughput and the rate of incoming demand is not a property of either one, and no amount of pre-deployment analysis surfaces it.
Staying is therefore not diligence. It is when the useful information arrives, and a delivery model that ends at launch has structured itself to leave immediately before the point of the exercise.
Leaving well
The exit condition is ownership, not launch. The work is finished when the organization no longer needs the person who built the system in order to operate, understand, or change it.
That has a testable form. Someone inside the organization can explain why the system works the way it does, not merely how to use it. Someone has changed it without the original builder present, and the change held. When it broke, the organization diagnosed the break itself. Until those have happened, the handover is a document rather than a transfer, and a system only its author can maintain is a liability with a good interface.

If this describes an operation you are responsible for, the diagnostic is where that conversation starts.
