3in3.dev is where I build and share systems like the Human Cooperation System (HCS) and the 3-in-3 SDLC Framework (3SF) – so teams can see and fix the real dynamics behind client–vendor projects.
The main lenses behind everything at 3in3.dev.
A way to look at teams as human cooperation systems – not just roles, tickets, and ceremonies. HCS helps you notice conditions like trust, safety, clarity, and alignment, and translate them into concrete actions.
A software delivery framework for client–vendor work where products, teams, and contracts must align. 3SF connects engagement, delivery, and value so you can see where projects really drift.
CLRF, DPPL, Question Space Builder, and other tools I’m building to think through work, relationships, and product decisions. Some are live, others are in the lab.
Most software projects don’t fail because people lack frameworks or tools. They fail when cooperation breaks before code is written: discovery and delivery drift apart, vendors and clients optimize for different realities, and nobody has a shared view of what’s really happening.
HCS and 3SF grew out of years inside client–vendor projects, trying to make those invisible dynamics visible and actionable.
3in3.dev is the place where I publish these systems, test them in real work, and keep them evolving.
