Deadlock is a situation in which two or more parties are unable to reach an agreement, resulting in a standstill. This can occur when each party has something they want that only another party can provide, and vice versa. The lack of communication or cooperation between the parties leads to a stalemate where no progress can be made. Deadlocks can happen in various settings such as business negotiations, political decision-making processes, or even personal relationships. To break a deadlock, the involved parties must find common ground and work towards a mutually beneficial solution.
