Affinity Estimation
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)

Architecture
Architecture Decision Record
Purposedifferent
When many tasks need to be classified quickly, it sorts them by perceived effort and similarity. It reduces the effort of fine-grained estimation for large volumes.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.An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable.
