Framework

Most systems start with parts and hope consistency follows. Sprawl usually follows instead. SOLAR ties every decision to outcomes and keeps the surface area lean.

The S.O.L.A.R. Model

Set Impact Goals

Start with outcomes, not components.

Define 3–5 goals with clear metrics: satisfaction (CSAT/NPS), task success, accessibility scores, performance budgets, and maintainability. Tie every system decision back to these goals.

Impact brief Success metrics KPI dashboard Baseline audits

Optimize and Lean

Ruthlessly reduce complexity.

Component rationalization, token hygiene, naming standards, and design-dev build budgets. Remove duplicates, merge variants, shrink props and options, cut asset weight.

Lean library plan Token map Variant matrix Performance guardrails

Lifecycle and Modularity

Design for change. Version intentionally.

Clear versioning, deprecation windows, upgrade paths, dependency mapping, and atomic composition. Small parts, well-named, with contracts you can trust.

Versioning policy Deprecation schedule Migration guides Module patterns

Agile Governance

Lightweight rules that speed you up.

PR/design reviews with checklists, RFCs for new patterns, scorecards, change logs, and "fast lane" approvals for low-risk updates.

Governance playbook Review checklists RFC templates Change log setup

Responsible User Influence

Patterns that guide, not manipulate.

Accessibility by default, inclusive content, ethical nudges, and research-backed decisions. No dark patterns.

Hi! I'm Ravi Palwe Product Designer. I've spent more than 20 years crafting large-scale, accessible, high-performing interfaces. SOLAR is how I respond to digital bloat: planet-first system you can use design tokens, energy-aware components, a media diet, and performance/carbon budgets baked into the process.
