• Identify a separate contract/likely separate contract (one contract) for an externalised activity (or activities) that generates an external exchange/likely exchange and assess qualitatively (using words) the nature/likely nature of this external exchange relationship and the level of the transaction cost economics variables.
• Critically comment, by reference to theory and practice, on how much this nature of the exchange decision/likely decision appears to be efficient, including explaining the way in which this decision/likely decision contributes to or undermines project outcomes.
