Software architecture evaluation methods such as ATAM have proven effective but most evaluation methods require external facilitation, extensive preparation or follow-ups or are difficult to integrate into fast-paced industrial development efforts. This session presents LASR, the Lightweight Approach for Software Reviews that enables development teams to conduct systematic, quality-focused architecture evaluations within a single half-day session

LASR is self-contained and team-driven, allowing 2-4 developers to perform the review without separate evaluation support. The method selects and characterizes key quality goals, before conducting a structured risk-based analysis and focused deep-dives in a few focus areas. The method is supported by an empirically grounded catalogue of standard risks derived from 100+ prior reviews, and delivers a concise “LASR result diagram” for management-compatible communication.

As there are many real-word applications of the method, we can report on its industrial application across different domains such as automotive, finance, energy, logistics, and embedded systems. Based on data from 75 independently conducted reviews, including deep-dive interviews with 18 reviewers, we discuss the method’s effectiveness, typical usage patterns, and practical limitations. The results indicate that LASR delivers actionable insights with modest effort. It offers a pragmatic addition to the current spectrum of architecture evaluation methods.
