Study design plans which configurations to measure, how measurements are allocated, and how long an experiment runs. It isolates a system change’s business impact while limiting time, performance, and implementation risk. section 1.2.1
A practical design makes the experiment answerable and efficient:
- Replicate individual measurements to improve reliability, randomize assignments to remove confounder bias, and prescribe the minimum sample size. section 2.4
- For adaptive optimization, define an initial parameter, measure its metric, fit a response surface, select the next parameter, and repeat. section 6.1.4
- Stop adaptive measurement when the response surface model and therefore the experiment design stop changing. section 6.1.4
A first configuration measurement
An optimization run begins at parameter value 0, measures CPU time, and records 1.2025010344211848. That observation becomes the basis for a response surface model and the design of the next experiment. section 6.1.4
