ECO.2:12 - Relations

ECO.1 restores a disputed calculation basis. ECO.3 explores a new exchange when existing offers no longer serve the plan. OPS.14 supplies a bounded operating comparison, MA.1 a resource-use account and FIN.6 an investment comparison. SYSE.9 obtains and applies a specialist engineering result when functional suitability remains unresolved. ECO.10 is needed when lower unit cost may change the total volume of activity.
