Big Bucket Schedule
A retention schedule that groups many record series into a few broad categories ("buckets") sharing one retention period and disposition, instead of scheduling each series individually.
Big Bucket Schedule (sometimes called flexible or large-aggregation scheduling) is an approach to records scheduling that collapses many narrowly defined record series into a small number of broad groupings, each governed by a single retention period and disposition action. Rather than maintaining hundreds of line items keyed to specific forms or processes, an agency assigns records to a handful of buckets — often aligned to business functions or to a common retention length.
This matters because traditional item-by-item schedules are costly to build, hard to apply consistently, and quickly outdated as systems change. Big buckets reduce that burden, simplify training, and make automated application in electronic systems far more feasible. The trade-off is precision: bucketing typically defaults a group to the longest retention any member requires, so some records are kept longer than strictly necessary.
For example, instead of separate series for travel vouchers, purchase requests, and expense reports, an agency might place all routine financial records into one bucket retained the same number of years, then disposed of together. This functional aggregation reflects modern guidance favoring simplified, flexible scheduling over granular itemization.
