This essay provides an informal review of the modern systems-centric biological methodology for the practical researcher. The systems approach is defined, and a generic recipe for employing it in biomedical research is offered. General caveats are discussed that pertain to biological complexity, to explanation in molecular terms, and to bottom-up investigation. An outlook on the development of systems biology is also given.
