Product work as a connected execution system.
ProjectBook models product development as a traceable chain of artifacts - from user insight to validated outcomes. Every decision has lineage. Every outcome has origin.
Fragmented tools break thinking.
Modern product teams scatter their work across disconnected systems. Each tool captures a slice of reality, but none of them speak to each other. Context collapses. Decisions lose their origin.
Not task management. Execution continuity.
ProjectBook enforces a structured lifecycle where every artifact is a link in a connected chain. Context, reasoning, and lineage are preserved at every step.
Story
User ResearchResearch becomes structured understanding. User stories capture real-world insight before any solution is considered.
Problem
Problem DefinitionStories surface structured pain points. Each problem is traceable to its originating insight — reasoning is never lost.
Idea
IdeationProblems generate solution explorations. Ideas are scoped, linked, and evaluated within the context of the problems they address.
Task
ExecutionIdeas become executable artifacts. Tasks inherit context from the idea they implement — execution is always purposeful.
Feedback
ValidationOutcomes feed back into the system. Feedback validates or invalidates the hypotheses that started the chain.
Artifacts are connected, not isolated.
Each artifact type represents a specific stage in product execution. They exist in relationship to each other — forming a traceable web of decisions and outcomes.
Captures user understanding — research, context, and the raw insight driving product decisions.
Structures and frames pain points derived from stories. Scoped, categorised, linked to root insight.
Represents solution explorations scoped to specific problems. Never floats in isolation.
Manages execution with full lineage to the idea and problem it implements. Context always present.
Validates outcomes against original intent. Closes the loop back to the story that started it.
Rich documentation artifact. Supports context without becoming part of the chain itself.
External references and links anchored to specific artifacts. Context without clutter.
Artifacts without meaningful linkage become visible as disconnected workflow states. The system surfaces orphaned artifacts — tasks without ideas, ideas without problems — communicating execution integrity issues before they become systemic failures.
Deliberate by design.
ProjectBook values deliberate execution over uncontrolled editing. The system enforces discipline — not as a constraint, but as a guarantee of coherence.
Explicit Saves
No autosave. Every commit to the system is an intentional act. Deliberate changes, deliberate context.
Intentional Progression
Workflow stages are enforced. Artifacts can't skip stages or exist without structural intent.
Validation Before Mutation
Data integrity is enforced at the boundary. Invalid state cannot persist. The system refuses chaos.
Permission-Aware Execution
Every action is permission-checked. The UI never shows what the backend wouldn't allow.
Remote Boundaries
Frontend and backend communicate across strict remote function boundaries — no leaking data contracts.
Deterministic State
Mutations are predictable. Side effects are explicit. Surprises are failures, not features.
"ProjectBook does not optimize for speed of editing.
It optimizes for integrity of thinking."
