The report won't necessarily include concrete steps to follow. They might be contained in another document altogether. The word 'actionable', like so many others, is often being used nowadays out of the original context that in case of 'actionable' was legal: actionable: "subject to or affording ground for an action suit at law". Your context might be legal, but it's not clear from the text you provided. If it is, you can make the "patřičné kroky" more specific. Otherwise, "patřičné kroky" should be enough to express the general meaning of "actionable" as "providing grounds for action". That might mean grounds for action in the sense of the timing being right or other conditions being satisfied to proceed with whatever action, i.e. starting a process that is not necessarily legal, but operational, e.g. starting a project.
