ABSTRACT
In developing a formulation, product or process, pharmaceutical or otherwise, the answer is rarely known right from the start. Our own past experience, scientific theory, and the contents of the scientific and technical literature may all be of help, but we will still need to do experiments, whether to answer our questions or to confirm what we already believe to be the case. And before starting the experimentation, we will need to decide what the experiment is actually going to be. We require an experimental strategy.
