Engineering principles
The technical principles that make Gymful systems dependable and adaptable.
1. Solve the system constraint
Understand the user, business, data, and operational problem before selecting a technical intervention.
2. Choose the simplest durable architecture
Avoid both fragile shortcuts and speculative infrastructure. Optimise for the known requirements, credible next changes, and the team that must operate the result.
3. Content and configuration are data
Editors should not modify large UI components for routine content changes. Use structured content, tokens, and clear configuration boundaries.
4. Progressive enhancement by default
Core content and actions should work without nonessential client JavaScript. Add interactivity where it materially improves the experience.
5. Accessibility and performance are functional requirements
Set budgets, test representative devices and input methods, and treat regressions as defects.
6. Make failure explicit
Design validation, empty states, retries, logging, and recovery. Silent failure is operational debt.
7. Secure the boundary
Validate input, minimise privileges, keep secrets server-side, update dependencies, and document external data flows.
8. Prefer reversible change
Use small releases, versioned migrations, backups, feature controls where justified, and clear rollback paths.
9. Observe what matters
Instrumentation should connect technical health and user behaviour to the intended business outcome.
10. Leave the system clearer
Update documentation, remove dead paths, name trade-offs, and capture lessons that should change the next implementation.
