DOCA.4:4.3 - Construct materially different directions
Vary the change that could make the contribution possible. Useful contrasts include developing a capability, making an existing capability usable through access or support, obtaining a qualified external contribution, changing the work or interface, or changing the proposed contribution itself. They are prompts, not mandatory candidate families.
Distinguish two questions:
- Different contribution premises: directions address different worthwhile problems, results, uses, or acceptance expectations. Preserve those differences for the receiving comparison.
- Different ways of obtaining one contribution: candidates hold the result premise stable but vary the supporting arrangement. For organization-change decisions, use OCE.8 when that whole same-result question is current.
Use PSD.8 when the receiving work is a bounded decision-support alternative set. PSD.8 can retain alternatives for different live formulations; same-result parity is not its universal entry condition.
Retain the actual baseline, a smaller repair, a staged direction, or no new development when each genuinely answers the inquiry. No change still carries continuing Work, resource use, and exposure. A missing alternative is an honest return; do not invent a weak candidate to make a preferred one win.
