  We provide a brief review of how phase-space techniques are explored within
strong-field and attosecond science. This includes a broad overview of the
existing landscape, with focus on strong-field ionisation and rescattering,
high-order harmonic generation, stabilization and free-electron lasers.
Furthermore, using our work on on the subject, which deals with ionisation
dynamics in atoms and diatomic molecules as well as high-order harmonic
generation in inhomogeneous fields, we exemplify how such tools can be used.
One may for instance determine qualitatively different phase-space dynamics,
explore how bifurcations influence ionisation and high-harmonic generation,
establish for which regimes classical and quantum correspondence works or
fails, and what role different time scales play. Finally, we conclude the
review highlighting the importance of the tools available in quantum optics and
quantum information to strong-field laser-matter interaction.
