Selected:LASR (Lightweight Approach for Software Reviews)User Interviews Failure Mode and Effects Analysis

Criterion	Architecture LASR (Lightweight Approach for Software Reviews)	UX Research User Interviews	Operations Failure Mode and Effects Analysis
Purposedifferent	LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail.	When teams derive needs only from assumptions and real motives are missing, user interviews give direct access to behavior and meaning. Conversations from the target group's everyday life make patterns, tensions, and open questions solidly visible.	For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability.
