| Closure and correction | A recipient needs a timely return, while new evidence or a material concern can invalidate part of it. |
| Analytical focus and participation | Detailed modelling needs concentrated effort; meaningful challenge needs attention when the interpretation is being formed. |
| Joint work and differentiated contributions | Working together can reveal important connections, while facilitation, technical judgement and choice have different conditions. |
| Local gain and transferred burden | Separation or parallelism can improve one contribution while adding delay, support effort or exclusion elsewhere. |
| Adaptation and continuity | The arrangement can change within an adequate Method’s allowed variation; a change to its action or joins can instead require Method reselection. |
| Remit and consequence | A facilitator may change discussion conditions without having authority to change participation rights, protection, budgets or the eventual decision. |
