One short email when something new ships. Nothing else. Every download above stays free and ungated.
The outside reading that's actually worth your time.
A short, opinionated shelf of the canonical references, each with who it's for and why we point you to it. We'd rather recommend six things well than list sixty.
INCOSE Systems Engineering Handbook
The profession's consensus reference for SE terminology, processes, and lifecycle activities.
Start here for shared vocabulary. When a lead says "do it by the book," this is the book.
NASA Systems Engineering Handbook (SP-2016-6105 Rev 2)
A free, thorough, example-rich walk through the full systems engineering engine.
The clearest public articulation of the SE lifecycle, and it's downloadable today, at no cost.
DoD Systems Engineering Guidebook
How systems engineering is expected to run inside the defense acquisition lifecycle.
Bridges textbook SE and the way programs are actually managed and reviewed.
SysML Distilled
Lenny Delligatti's concise field guide to SysML: the modeling language behind the diagrams, distilled to what you actually use.
The friendliest on-ramp to SysML that still works as a desk reference. Read it alongside the Cameo guides.
Adaptive Acquisition Framework (AAF) Pathways
The six pathways the DoD uses to field capability, from urgent needs to major programs and software-centric efforts.
The map of how your program is structured and funded, and the context every artifact you write ultimately serves.
OMG SysML Specification
