B.5.PI:3 - Forces
| Need | Difficulty |
|---|
| Begin before a problem is recognized | A worker absorbed in producing a result has no independent reason to search for another method. |
| Learn from successful work | An adaptation can reveal a dependency worth changing, or be the best available way to do the job. |
| Preserve an emerging concern | Familiar terminology and a listener’s expertise can replace what has not yet been expressed. |
| Obtain a meaningful comparison | A rare value can be valid; a routine outcome can fail its intended use. |
| Keep the whole work going | Attention, advice and investigation consume resources and can disrupt the action they support. |
| Share the work of inquiry | A participant can supply a cue without knowing its cause; another contribution must make interpretation or action possible. |
