Measures of project success are best expressed in concrete terms known as metrics because metrics provide a clear, quantifiable way to assess the performance and outcomes of a project. Metrics allow for objective evaluation of whether project goals were achieved, using specific data points that can be measured and analyzed. This clarity is vital for stakeholders to understand project performance and for making informed decisions about future projects or adjustments needed during the project's lifecycle.

Concrete metrics can include measures like time, cost, quality, and scope, which can be tracked and equated to predefined success criteria. Using metrics not only fosters accountability but also enables benchmarking against industry standards or past projects, facilitating cooler comparisons and process improvements.

In contrast, expressing project success in abstract terms can lead to misunderstandings or misinterpretation of what constitutes success. Stakeholder satisfaction is important, but it can be subjective and varies from person to person, making it less reliable as a standalone measure. Additionally, relying on subjective evaluations can introduce biases and make it difficult to convey a unified and factual understanding of project performance. Metrics, however, provide the objective data necessary for comprehensive evaluation and reporting.
