In this review we focus on the role of jets and outflows in the star formation process. Are jets/outflows merely an epiphenomenon associated with star formation or do they play an important role in mediating the physics of assembling stars both individually and in a global sense? To address our questions we focus on the current state of observations and on the important points of contact between these observations and theory. We review the Jet/Outflow phenomena by organizing our questions into 3 length-scale domains: Source and Disk Scales (1-10^2 AU) where the connection with protostellar and disk evolution theories is paramount; Envelope Scales (10^2-10^5 AU) where the chemistry and propagation shed further light on the jet launch process, its variability and impact on the infalling envelope. Parent Cloud Scales (10^5-10^6 AU) where issues of large scale feedback on the global star formation process become important. In addition to describing results from established platforms like the HST (multi-epoch imaging and spectroscopy) we also review new results from facilities that are currently coming on-line (ALMA, the Jansky Array (EVLA), e-MERLIN. In describing these observations we look to the future and consider the questions that these new facilities can address. We also review results on jet dynamics from emerging field of High Energy Density Laboratory Astrophysics (HEDLA) that provide direct insights into the 3-D dynamics of fully magnetized, hypersonic, radioactive outflows.
