What type of project control tool measures attributes of system elements?

The correct choice is the technical performance measure, which is a project control tool specifically designed to assess and quantify the attributes of system elements. Technical performance measures (TPMs) provide a structured approach to evaluate whether the system's performance attributes—such as size, weight, power consumption, reliability, or any other critical characteristics—meet predefined goals or requirements throughout the project's lifecycle.

By establishing performance thresholds or objectives, TPMs allow systems engineers and project managers to monitor progress, identify potential issues early, and make informed decisions to guide the project towards successful completion. This makes TPMs particularly valuable in ensuring that the systems' design and implementation stay aligned with the intended performance specifications.

The other options have different focuses or applications that do not directly measure system attributes in the same way. Risk assessment tools evaluate potential risks that could impact project success, satisfaction surveys gauge user or stakeholder satisfaction, and quality assurance checklists are used to ensure that standards and practices are followed during development. While each of these tools plays a critical role in project management and systems engineering, they do not serve the specific function of measuring system attributes like the technical performance measure does.
