Item The application of complexity theory to contracting out public health interventions : a thesis presented in fulfilment of the requirements for the degree of Master of Philosophy, School of Health at Massey University, Wellington, New Zealand(Massey University, 2019) Oakden, Judith PenelopeThe New Zealand government has used a policy approach called New Public Management since the 1980s to contract out public health services. Under this approach contracting out works well for public health services that are predictable, stable and controllable. However, the approach does not always work so well for hard to specify, complex to deliver services, where it is challenging to measure whether the right people benefit. Complexity theorists suggest that public services are complex adaptive systems and therefore do not respond in linear, predictable ways. Complexity theorists also suggest New Public Management framing of contracting out is too simplistic and overlooks the needs of some important population groups, in its quest for efficiency. The overall objective of the research was to explore contracting out of public health services using a general complexity framing to see what insights it might add. The research considered: which ideas from within complexity theory might provide a possible frame to examine contracting out practices; how complexity theory might inform contracting out practice for public health services; and how public sector managers might understand the processes and dynamics of contracting out if informed by complexity theory. A review of complexity and public management literature identified four complexity concepts used to frame interview questions and analyse results for this research: path dependence, emergence, self-organisation and feedback. A small-scale qualitative study used a theory-based approach to test the complexity concepts with public sector managers experienced in contracting out for public health and social services. This research argues that a framing informed by complexity theory resonated with public sector managers in understanding and working in the messy ‘realities’ of contracting out. This research observes that contracting out is often not tidy, linear and controllable as suggested by New Public Management practices. Public sector managers seeking to try new contracting out approaches, can find the underlying New Public Management ethos found in many administrative arms of government hampers them. This research provides insights about why change is hard to achieve, as well as offering public sector managers some alternative ways to think about how they contract out public health services.Item Tackling complexity using interlinked thinking : well-being as a case study : a dissertation presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Ecological Economics at Massey University, Palmerston North, New Zealand(Massey University, 2016) Forgie, Vicky ElizabethThe world today is made up of a series of highly interconnected complex systems characterised by uncertainty. Human minds struggle with complexity, and the tools available to help us are limited. This often leads to reductionism, focusing on the parts rather than the whole. Working with individual parts ignores the dynamics that result from interdependencies between components. It is these interactions that determine the behaviour we experience in real world situations. This dissertation presents ‘interlinked thinking’ as a communication and analytical approach to help people work with, rather than ignore, complexity. It aims to build understanding of feedbacks loops and systems in a way that does not require expert modelling skills. It is a participatory process that allows people not familiar with systems thinking to have a structured dialogue on how components interrelate, and share their mental models. Links between components are debated and decided on in a workshop session. The resultant causal loop diagrams are transcribed to a matrix and an algorithm run to analyse the links in the system. The interlinked thinking method was tested using three case studies to answer the principal research question: Does understanding the relationships between indicators add value and progress sustainable well-being? Well-being is multi-dimensional, and the complex behaviour of the well-being system does not come from individual indicators but from the interrelationships between indicators and resultant feedback loops. Participants who applied interlinked thinking confirmed value was gained from: (1) increased understanding of the indicators in the system; (2) more visible relationships; (3) expanding the toolkit to work with complexity; (4) an increased ability to bring important issues to the attention of decision-makers; (5) consideration of intervention impacts; and (6) encouraging integrated thinking. Interlinked thinking can be replicated and used in any situation where having a better understanding of interconnectedness is important but time, resources, and modelling skills are limited.
