Ford en Fiat gebruiken vaak de term GPDS, die staat voor:
GPDS:
Global Product Development System - The process tasks and deliverables necessary to develop and launch a vehicle. Team events and milestones are defined to communicate progress at various points throughout the process.

deliverable (Webster's): Something that can be provided as the product of development;
maar volgens mij hier niet bedoeld in enge zin (producten), maar in ruime zin: te leveren prestaties (IATE) (producten, diensten, projectvereisten), te verwachten resultaten,

What Does Deliverables Mean?
A project management term for the quantifiable goods or services that will be provided upon the completion of a project. Deliverables can be tangible or intangible parts of the development process, and are often specified functions or characteristics of the project.
Investopedia explains Deliverables
Deliverables serves as a general term that encompasses the requirements of a project. A deliverable may be an object, used in the greater scheme of the project. For example, in a project meant to upgrade a firm's technology, a deliverable may be a dozen new computers.

Alternatively, a deliverable may be a function or aspect of the overall project. For example, a software project may have a deliverable specifying that the computer program must be able to compute a company's accounts receivable.

Misschien is ipv "essentiële te leveren prestaties" "te leveren sleutelprestaties" ook een optie

The key deliverables are the results that need to be delivered fit-for-purpose as identified in the project charter.
Example project deliverables:
•Project Charter
•The web application
•System Design
•Building blueprint

'Deliverables' zijn normaliter op te leveren (eind)producten of (eind)resultaten. In combinatie met 'key' zou ik dit formuleren als '(de) belangrijkste op te leveren (eind)producten/(eind)resultaten'.
