Oimcwdf-Rom Design-for-Efficiency Some systems and products require focused consideration on efficient utilization of resources. In these cases a Design-for-Efficiency objective must be established. Design-for-Effectiveness One of the key contributors to User satisfaction is a system product or service s degree of effectiveness. Did the missile hit and destroy the target Does the flight simulator improve pilot effectiveness Establish Design-for-Effectiveness objectives where the effectiveness is the key determinate for mission success. Design-for-Reconfigurability Some systems and products are designed to accommodate a variety of missions as well as a quick turnaround between missions. Therefore some may have to be reconfigurable within a specified time frame. Design-for-Integration Test and Evaluation Objective Modular system and products that undergo multiple levels of integration and test require a Design-for-Integration Test and Evaluation objective. Ideally you would isolate each configuration item CI and test it with actual simulated stimulated or emulated interfaces. If the system or product is to be integrated at various facilities special interface considerations should be given to physical constraints and equipment and the tools available should be investigated. Finally EQUIPMENT-based systems and products must be designed to facilitate multi-level system verification and validation. This requires the incorporation of temporary or permanent test points and access ports for calibration and alignments among other things. Design-for-Verification Objective Once the system or product is integrated tested and ready to be verified designers must consider HOW the item will be verified. Some requirements can be physically verified other requirements may not. Establish a Design-for-Verification objective to ensure all data required for verification are accessible and can be easily measured. .
