Abstract:	In the National Office of a big-four accounting firm, Ernst & Young's Quantitative Economics and Statistics Group (QUEST) conducts more than 150 samples annually to estimate values in regulatory, audit, and litigation settings. There is constant pressure in private industry to deliver complex analyses with short notice---within a week or even a day. Often, after the sample is drawn and the study in progress, newly discovered information will alter the sampling frame, requiring design adaptations and more detailed computations later. When audit and survey results are returned for estimation months later, staff who performed the original work may be juggling multiple projects and will work late to accommodate the deadline. Some may even be unavailable due to turnover or their current assignments. In this setting, there are many factors that can lead to errors, inefficiencies, and difficulties reproducing our work. Yet trust in our quality is critical to our business, efficiency is essential for profitability, and a clear audit trail is mandatory.
