System Performance Analysis And Process Improvement: A Perspective On Healthcare
2014
Several management approaches focus on processes and system
performance analysis in order to achieve ‘continuous’ (or more accurately
continual) improvement in organisations. The main focus of the present
research has been on applying Business Process Management (BPM),
Theory of Constraints (TOC) and Discrete-Event Simulation (DES) to
healthcare processes. BPM is a discipline dealing with the management of
business processes; on the other hand, TOC promotes improvement by
focusing on the system constraint(s), which limits the system performance..
DES helps to visualise process behaviour, measure process operational
performance and also evaluate different scenarios for improvement.
In particular, this research employs the Business Process Model and
Notation (BPMN) modelling standard as a process/conceptual mapping tool
and as a gateway to TOC and DES modelling in an effort to overcome
barriers to stakeholder engagement.
The main contributions of the work in this thesis are demonstration of the
effectiveness of BPMN in these roles (in particular to achieve fully-facilitated
DES in healthcare and, where this remains not practicable, to describe the
further barriers), the potential value of extending the BPMN 2.0 toolset, and
demonstration of the adaptation of TOC’s Drum-Buffer-Rope (DBR) tool to
healthcare.
