| Cultural continuity | Practice needs carriers and memory, while preserved artifacts can outlive actual use and recognition. |
| Reproduction and variation | A recipient needs the reasons and constraints that make a way useful, while copying every historical step can prevent adaptation and unrestricted improvisation can lose those constraints. |
| Deliberate intervention | A team can change identified cards, descriptions, rules, Systems, Work occurrences, or direct relations within authorization, while it rarely controls the whole population or field. |
| Relation specificity | Generation, transmission, recognition, selection, retention, memory, and loss interact, while each needs different participants and evidence. |
| Local Work | Individual choices and enactments are observable, while they do not automatically aggregate into a cultural relation. |
| Time | Transmission can be observed quickly, while retention and loss require later intervals. |
| Consequences | Cultural change should matter to practitioners or constructed Methods, while consequence and causal relation remain separate. |
| Case variety | Institutional, organizational, and project cases illuminate different relations, while joining their histories invents a population. |
