This document discusses how to benchmark the maturity of a SaaS solution. It describes the main approaches to building a SaaS product as either single-tenant or multi-tenant. It also outlines the key areas - architecture, security, operations, and configuration - that constitute a complete SaaS solution and should be benchmarked. A tool called SMART is introduced that helps companies assess the maturity of their existing or planned SaaS product across these areas through a standardized reporting process.
