Which design feature is NOT likely to improve supportability?

• A. Use of modular components to ease replacement
• B. Standardized interfaces for quick maintenance
• C. Diagnostic tools integrated into equipment
• D. Requirement for highly trained individuals to perform routine maintenance

Answer: (D)

Design for maintainability and supportability aims to reduce downtime and make repairs and upkeep as quick and easy as possible. Modular components enable fast replacement of faulty parts without disassembling the whole system, which speeds repairs and lowers complexity. Standardized interfaces mean technicians can use common tools and procedures across devices, reducing training time and avoiding custom work for each unit. Integrated diagnostic tools let the system identify faults and guide maintenance, speeding troubleshooting and often enabling remote monitoring or on-site fixes with minimal skill requirements. Requiring highly trained individuals for routine maintenance, however, creates bottlenecks, increases cost, and slows down upkeep, which does not improve supportability.
