Measuring quality
«When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.»
— Lord Kelvin (1824 – 1907)
Performance measurements
• Statistical models.
• Lab setup.
• Load generation tools and data.
• Measurement tools and reporting.
• Diagnostics to identify bottlenecks.
• System skills.
