Ensuring the precision of hardware is an essential element of a properly functioning system, as mentioned in the sections on System Verification, Testing, and Maintenance.
Although these sections divide hardware, software, and communications into distinct topics, their functionality is frequently interconnected. Therefore, the subsequent validation, testing, and maintenance processes may require simultaneous attention to all three components.
Qualification tests also referred to as hardware verification tests may encompass:
- Hardware testing conducted to replicate real-life scenarios, encompassing storage, transportation, operation, and maintenance conditions.
- Verification of hardware compliance with local environmental standards, covering shelter, space, furnishings, electrical power, and varying temperature, humidity, and pollution levels.
- Thorough review of documentation to ensure completeness and adequacy.
- Validation of hardware performance under both normal and abnormal conditions.
- Implementation of security measures in accordance with relevant standards and quality assurance protocols.
Evaluation of hardware performance
Thoroughly implementing a well-organized testing program guarantees the examination of every component within a system. This becomes particularly crucial when dealing with critical systems like electronic voting systems. Various testing approaches can be adopted to ensure the accuracy and reliability of these systems:
- Developing a set of evaluation standards
- Implementing non-operational assessments to validate equipment durability during physical handling, like transit drop trials
- Reviewing any embedded code in hardware (also known as firmware) to confirm logical accuracy and adherence to standards
- Executing functional assessments to confirm compliance with evaluation standards
- Utilizing qualitative evaluations to verify adherence to evaluation standards
- Performing evaluations in controlled laboratory settings and various real-world scenarios
- Carrying out assessments over an extended duration to ensure consistent system performance
- Conducting load tests to replicate real-world conditions and surpass expected data amounts
- Validating input-output consistency by inputting known data and comparing the output with the input.
Maintenance of hardware components is essential for ensuring the smooth functioning and longevity of computer systems:
- After the verification, testing, and implementation of hardware, it is essential to continue with regular maintenance to ensure optimal performance.
- The maintenance procedures will differ based on the type and complexity of the technology being used.
- Manufacturers or suppliers often provide maintenance schedules or programs for hardware items.
- Maintenance services may also be included in the purchase agreement with the manufacturer or supplier.
- Ongoing monitoring and testing plans should be established to identify and address maintenance needs promptly, especially for systems in long-term use.
