Criterion
Four paper stations connect system purpose, quality goals, risk cards and focused investigation with a target and gap profile.

LASR (Lightweight Approach for Software Reviews)
Paper illustration for DMAIC.
Operations
DMAIC
Paper illustration: scenarios and architectural decisions are connected to identified risks.

ATAM (Architecture Tradeoff Analysis Method)
Paper illustration for Failure Mode and Effects Analysis
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.For a process problem with fluctuating performance, the method brings analysis and improvement into a disciplined sequence. It creates a framework in which numbers, causes, and control come together.ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation.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.
