English to Italian Tech/Engineering Engineering (general) Operations

vi metto un bel po' di contesto, per capire di che si tratta:

"The engineers in the various disciplines, for instance, created and widely distributed a set of checklists and memo templates to be used as guides for making requests and promises. The checklists specified a half-dozen or so aspects of any request or promise that must be explicit to both parties. These included names, dates, underlying rationales for requests, the skills necessary to fulfill promises, and so on. The engineers also established periodic **design freezes**, during which design coordinators, referring to their checklists, would ensure that customers and providers maintain identical understandings of their requests, promises, and counteroffers."

credo di aver più o meno intuito che cosa significa... ma non riesco a trovare un'espressione adeguata per tradurlo. any ideas?

grazie mille!!
