NOUN + 次第 (だ/で) as “depends on NOUN”
The noun 次第 (しだい), which can translate to “dependent upon,” can be used with a NOUN to express that something is dependent upon said NOUN. This something can simply be another entity (in which case だ or です is used to close the statement), as well as an action, in which case the particle で follows after 次第 to connect to the verb phrase.
