|---|---|---|---|---|
Purposedifferent | When work needs to move between different states or columns, it makes that movement and its handoffs legible. It sorts work by value, risk, and delivery ability. The result is captured as a ROAM Board and an Owner List. | For a tightly scoped process segment with noticeable waste, the method bundles shared energy for change. It suits situations that call for fast learning loops and visible adjustments. | 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. | 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. |
