| Scope control | Task-level work is enough, and your team can own architecture, priorities, and acceptance criteria internally. | You need one accountable owner to define boundaries, sequence tradeoffs, and protect sprint outcomes. |
| Coordination overhead | Stakeholder coordination is lightweight, and handoffs can be managed without dedicated delivery leadership. | Cross-functional alignment is complex enough that unmanaged handoffs increase delay and rework risk. |
| Risk ownership | Your team can absorb execution ambiguity and resolve technical or product conflicts quickly. | You need explicit risk management, decision checkpoints, and delivery guardrails inside the engagement model. |
| Outcome accountability | You mainly need execution capacity and can evaluate success by completed tasks. | You need accountability to business outcomes, not just task throughput. |
| Time-to-value certainty | Timeline is flexible and can tolerate iterative drift while direction stabilizes. | Timeline certainty matters, and bounded sequencing is required to ship a defined result quickly. |
