Data Management

Many DOD systems undergo operational testing, which is a field test involving realistic combat conditions. Data, analysis, and reporting are the fundamental outcomes of operational test, which support leadership decisions. The importance of data standardization and interoperability is widely recognized by leadership in DoD, however, there are no generally recognized standards for the management and handling of data (format, pedigree, architecture, transferability, etc.) in the DOD. In this presentation, I will review a set of data principles that we believe DOD should adopt to improve how it manages test data....

Version control software manages, archives, and (optionally) distributes different versions of files. The most popular program for version control is Git, which serves as the backbone of websites such as Github, Bitbucket, and others. In this mini- tutorial, we will introduce basics of version control in general, and Git in particular. We explain what role Git plays in a reproducible research context. The goal of the course is to get participants started using Git....

IDA analysts strive to communicate clearly and effectively. Good data visualizations can enhance reports by making the conclusions easier to understand and more memorable. The goal of this seminar is to help you avoid settling for factory defaults and instead present your conclusions through visually appealing and understandable charts. Topics covered include choosing the right level of detail, guidelines for different types of graphical elements (titles, legends, annotations, etc.), selecting the right variable encodings (color, plot symbol, etc....

Reusing Test and Evaluation (T&E) datasets multiple times at different points throughout a program’s lifecycle is one way to realize their full value. Data management plays an important role in enabling - and even encouraging – this practice. Although Department-level policy on data management is supportive of reuse and consistent with best practices from industry and academia, the documents that shape the day-to-day activities of T&E practitioners are much less so....

Analyses are reproducible if the same methods applied to the same data produce identical results when run again by another researcher (or you in the future). Reproducible analyses are transparent and easy for reviewers to verify, as results and figures can be traced directly to the data and methods that produced them. There are also direct benefits to the researcher. Real-world analysis workflows inevitably require changes to incorporate new or additional data, or to address feedback from collaborators, reviewers, or sponsors....

In operational testing, survey administration is typically a manual, paper-driven process. We developed a web-based tool called Survey Testing Automation Tool (STAT), which integrates and automates survey construction, administration, and analysis procedures. STAT introduces a standardized approach to the construction of surveys and includes capabilities for survey management, survey planning, and form generation. Suggested Citation Finnegan, Gary M, Kelly Tran, Tara A McGovern, and William R Whitledge. Survey Testing Automation Tool (STAT)....

The fundamental purpose of test and evaluation (T&E) in the Department of Defense (DOD) is to provide knowledge to answer critical questions that help decision makers manage the risk involved in developing, producing, operating, and sustaining systems and capabilities. At its core, T&E takes data and translates it into information for decision makers. Subject matter expertise of the platform and operational mission have always been critical components of developing defensible test and evaluation strategies....
