The U.S. military try and review Command (ATEC) is chargeable for the operational checking out and review of military structures in improvement. ATEC

requested that the nationwide examine Council shape the Panel on Operational try layout and overview of the meantime Armored car (Stryker). The cost to this panel was once to discover 3 concerns about the IOT plans for the Stryker/SBCT. First, the panel used to be requested to envision the measures chosen to evaluate the functionality and effectiveness of the Stryker/SBCT compared either to specifications and to the baseline procedure. moment, the panel was once requested to study the try out layout for the Stryker/SBCT preliminary operational attempt to work out if it is in step with top practices. 3rd, the panel was once requested to spot the benefits and drawbacks of innovations for combining operational try out info with facts from different assets and kinds of use. In a prior file (appended to the present record) the panel provided findings, conclusions, and suggestions concerning the 1st concerns: measures of functionality and effectiveness, and try out layout. within the present file, the panel discusses innovations for combining information.

In particular, the residuals are useful to examine to assess conformity with assumptions of linearity, homogeneous variances, and existence of outliers. Such a model would be determined by a small number of parameters, which can be estimated using all sample values simultaneously (by the method of least squares, for example). , used jointly, in estimating these few parameters. The accuracy of such estimates of the conditional means provided by the fitted values from the regression model is much greater than that afforded by just using the mean EXAMPLES OF COMBINING INFORMATION 25 of all sample values for data collected at the covariates of interest, if they were even available.

Test Planning Operational testing and evaluation of military systems involve substantial resources and time, and the decisions to be made have important consequences for national security. Given the high stakes, it is critical that operational testing be planned and executed carefully and systematically and that as much relevant prior information as possible be taken into account in designing efficient test plans. It is difficult, and in some cases impossible, to generate useful information from a poorly designed test plan.

20 IMPROVED OPERATIONAL TESTING AND EVALUATION Many industrial organizations have recently instituted systematic processes for planning and executing large-scale experiments based on quality management principles such as six sigma. A key component of this process is the use of templates for systematic elicitation and incorporation of prior information. , functions that specify the relationship between signals and responses); and documenting subject-matter knowledge and relevant background from past studies.
