Abstract
Within the systems movement, there are multiple paths to develop systems methodologies and systems thinking. One way is to review various management technologies (e.g., Operational Research (OR), Information Systems Design, Accounting and Logistics Management) from a systems perspective. Multiperspective, Systems-based (MPSB) Research is a research programme, based on Critical Systems Thinking, that works along this path. A brief review of OR and Business Processing Re-engineering (BPR) is provided to facilitate an introduction to the MPSB research. This paper also defines the MPSB research and the terms used in it.
