Why is Quality Improvement so Challenging? A Viable Systems Model Perspective to Understand the Frustrations of...

The challenges facing Quality Improvement Managers (QIMs) are often understood and addressed in isolation from wider healthcare organisation within which quality improvement initiatives are embedded. We draw on Stafford Beer's Viable System Model (VSM) to shed light on how the viability of quality improvement depends on the effective functioning of five critical quality improvement systems and the extent to which these systems are integrated within the healthcare organisation. These systems are System 1 (Operations), System 2 (Coordination), System 3 (Operational Control), System 4 (Development) and System 5 (Policy). Our analysis draws on interviews with 56 QIMs working in 15 of New Zealand's 20 District Health Boards. We use VSM to identify the sources of problems in QI implementation. These include changes in direction for QI initiatives; myopic behaviour resulting from fragmented systems of care; difficulties in managing and monitoring QI activities given variable staff engagement and inadequate resourcing; pressure for quick results rather developing QI capabilities; and a lack of strategic embeddedness. A viable QI system requires QI approaches that are (1) implemented at an organisation-wide level; (2) well-resourced and carefully monitored; (3) underpinned by a long-term vision; and (4) supported by QIMs with the necessary power and influence to integrate QI subsystem within the wider healthcare organisation.
