No company needs full-time specialists in every discipline. When workload rises or an expertise you do not hold is required, we act as an extension of your team for as long as you need it.
The scope is agreed in writing at the outset: which deliverable, by which date, in which format. The work follows your documentation standard and revision practice — we do not impose ours on you. There is one technical counterpart throughout the project, so communication does not scatter.
Most often in three situations: when a deadline approaches and the team is short, when an expertise you do not hold is needed (CAN communication architecture or harness design, for instance), or when an existing design needs an independent review. In all three the goal is the same — getting it right without slowing the work down.
