Two engineers are in open conflict: one insists the release must ship on Friday, the other insists it must be delayed. Each has restated their position several times. What is the most useful first move for whoever is helping them resolve it?
Explication
'Ship Friday' and 'delay' are stated positions; the underlying needs — for example an external commitment on one side and an unmitigated risk on the other — are usually different things, and options may exist that satisfy both, such as shipping on time behind a feature flag. Splitting the difference (option 1) is a compromise chosen before anyone knows what has to be protected, so it may satisfy neither need. Deciding by seniority (option 2) settles the argument without using the information either engineer holds. Waiting (option 4) postpones a decision that has a date attached to it.
