For combat vehicles such as the Stryker, the standard practice is to create combat situations similar to those in which the test vehicle would be expected to perform. The system is then inserted into the combat situations with trained operators and with an opposition force (OPFOR)

Factors that must be considered in the evaluation of the test data are: . Modeling and simulation using the results of the live test, accounting for the uncertainty due to small sample size in the live tests.

When ATEC is assigned the responsibility for performing test and evaluation for a given system, several documents are developed: · the test and evaluation master plan, · the test design plan, · the detailed test plan, · the system evaluation plan, and · the failure definition and scoring criteria. Testers perform a developmental test on the early production items in order to verify that the specifications have been met or exceeded (e.g., a confirmation, by noncontractor personnel, of the product verification test results on delivered systems)

The IOT consists of two sets of operational trials, currently planned to be separated by approximately three weeks: one using the IBCT/ Stryker, the other the baseline LIB. Each trial is scheduled to have a nineday duration, incorporating three types of mission events (raid, perimeter defense, and security operations in a stability environment)

Constraints on Test and Evaluation The test ancl evaluation design ancl execution are greatly influenced by constraints on time, money, availability of trained participants, ancl availability of test vehicles, as well as by demands by the contractor, the project manager, the director of operational test ancl evaluation, ancl Congress. In the IBCT/Stryker JOT, the time constraint is especially critical.

In fact, it will be feasible to do only a few of the possible treatment combinations needed to consider the quality of the intelligence, the countermeasures against it, the quality of transmission, and how much information should be given to whom. CURRENT STATISTICAL DESIGN The IBCT/Stryker IOT will be conducted using two live companies operating simultaneously with a simulated company.

The variable "time of day," which refers to whether the mission is mainly carried out during daylight or nighttime, is not explicitly mentioned in the design matrix. Although we assume that efforts will be made in real time, opportunistically, to begin missions so that a roughly constant percentage of test events by mission type, terrain, and intensity, and for both the IBCT/ Stryker and the baseline companies, are carried out during daylight and nighttime, time of day should be formalized as a test factor.
