|---|---|---|---|---|
Purposedifferent | For a critical top event with several possible triggers, the method logically models failure paths. It makes visible which combinations of conditions can lead to damage. | The Strategy Execution Loop helps avoid treating strategy as a one-off document. It makes visible how strategic decisions are turned into objectives, initiatives, operational work, measurement, and learning. | 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, 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. |
Complexitydifferent | High | High | Medium | High |
Timedifferent | 2-6 h | Initial 3-6 h, then monthly or quarterly reviews | 3–4 h for initial assessment; preparation and deeper analysis additional | 2-6 h |
Participantsdifferent | 3-8 | 5-12 | 1 or a small team; particularly suitable for 3–4 people | 3-10 |
