{"Image DocumentName": "General Guidelines 5. Perform a screening experiment", "Image ImageDescription": "A screening experiment is useful to reduce the number of process variables to a manageable number and thereby reduce the number of experimental runs and costs associated with the entire experimentation process. For example, one may be able to study seven factors using just eight experimental trials. It is advisable not to invest more than 25% of the experimental budget in the first phase of any experimentation such as screening. Having identified the key factors, the interactions among them can be studied using full or fractional factorial experiments (Box et al., 1978). Lotfi K. Gaafar \u00a9 2003 QA Publishing, LLC.
