A colleague count describes adoption; a cumulative search count describes use over an unstated interval; a daily email count describes processing volume. None supplies minutes saved per successful case.","For a defensible comparison, collect eligible tasks, completed tasks, correction time and failure rate over the same period. Then calculate net time per completed task. Treat a developer adoption target as a future checkpoint, separate from measured output. The ledger below gives each number a job and makes the missing evidence explicit."],"headers":["Reported measure","Unit / time basis","Missing input","Valid use"],"rows":[["More than 16,000 colleagues","People who adopted the assistant; cumulative","Eligible population, current active users","Adoption scale only"],["Over one million searches","Search events since launch; interval unspecified","Observation dates, successful answers, repeat users","Use volume only"],["Approximately 120,000 emails daily","Processed messages per day","Rework, exceptions, manual time, completion quality","Throughput only"],["50% developer adoption by end of 2026","Planned share of developer population","Observed adoption at that date","Future comparison checkpoint"]],"limits":"Interested-party announcement, not an independently measured bank outcome.
