What was the core algorithmic focus of early ACD systems regarding destination selection?

Answer

Sequential searches or time-based measurements

The algorithms governing the initial Automatic Call Distributor (ACD) systems were intentionally straightforward because the primary goal was managing volume and ensuring no call went unanswered if an agent was available. The decision-making process relied on simple methods like sequential searches, where the system checked Agent A, then Agent B, and so on, until an idle party was found. Alternatively, some systems used time-based measurements to gauge availability. This established a rigid logic where all calls and agents were treated identically unless explicitly programmed otherwise, focusing purely on finding the *next available* recipient rather than the *best* one.
