What is the primary consideration when assessing whether a manufacturing contract is enforceable regarding changes made to machinery?

The enforceability of a manufacturing contract, particularly with respect to changes made to machinery, primarily revolves around the nature of the goods being produced and how those changes impact the contract's terms. In this case, the correct answer highlights that the fundamental concern is not just about the total price of the contract, but rather how changes to machinery can affect the goods being produced and the obligations of the parties involved.

When assessing this enforceability, courts typically look at several factors, such as whether the specifications have changed, how those alterations affect production timelines, and the quality of the output. It is critical to understand the context in which the changes to machinery occur, as modifications might make it impossible to deliver goods that conform to contract specifications, thus impacting enforceability.

Therefore, the primary focus is on how changes to the machinery affect the manufacturing process and whether the goods meet contractual criteria, rather than merely looking at the total contract price irrespective of the completion status. This approach ensures that the mutual obligations of the manufacturing agreement are adequately considered, leading to a better assessment of enforceability.
