Process is a certain sequence of actions aimed to achieve certain business goal. As such this schema has no immediate value. Value appears when a process runs within an intended business environment.
Process cannot operate in vacuum. To start and achieve its goals process requires a set of initial conditions, prerequisites and actors, which further interact in various ways to produce certain results of the process. These can be commonly referenced as business objects and tenants of the process.
In a wide sense, most business objects can be considered as a sort of content. Even in case when an object is not purely IT based but has specific physical representation, such as a building, vehicle or equipment, it still has a mirror projection in an IT system to denote it as a process content.
In this sense, practical execution of the process always involves relevant content management. Vice versa, any manipulation of content always goes on a certain process, either implied or explicitly enforced and supervised.
