ECO.6:4.3 - Choose the smallest sufficient arrangement
Compare like intended service and disturbance conditions, including investment exposure, operating performance, delay, enforcement and exit. Use conditional comparisons when a future disturbance cannot be assigned a defensible probability.
Choose or retain an arrangement whose participants can actually supply its contributions. Explain what it protects, which adaptation remains possible and when the choice must be reopened. A relevant unresolved legal or technical condition can limit the conclusion; investigating every conceivable future dispute is unnecessary.
