Process management is the ensemble of activities of planning and monitoring the performance of a process, especially in the sense of business process, often confused with reengineering. Jörg Becker, Martin Kugeler, Michael Rosemann (eds.).Process Management. ISBN 3-540434-99-2
Process Management is the application of knowledge, skills, tools, techniques and systems to define, visualize, measure, control, report and improve processes with the goal to meet customer requirements profitably. It is different from program management in that program management is concerned with managing a group of inter-dependent projects.
ISO 9001 promotes the process approach to managing an organization.
...promotes the adoption of a process approach when developing, implementing and improving the effectiveness of a quality management system, to enhance customer satisfaction by meeting customer requirements. Source: clause 0.2 of ISO 9001:2000

In computer science, a process is an application in execution. When a process is using the CPU, it is actually running and doing some work. However, it will not always stay in that state. If a process does I/O and the device is not ready or just slow, the process will become blocked and be unable to do any more work until the I/O is complete.
In a multitasking environment, a process is not allowed to use the CPU all the time. At intervals (maybe signalled by a timer interrupt) it will be stopped by the O/S so that another process can run. In this state it is not running, but is runnable. Unix implementation includes process scheduling, interrupt handling, signaling and process priorization among others features.
