Purpose This paper has two parts, namely, Part 1 and Part 2. The purpose of this paper (Part 1) is to explain an adaptive relational paradigm that can efficaciously respond to the complex issues in wicked problems. A relational paradigm can work across the disciplines and fields that characterise wicked problems. It is also methodologically plural - that is it uses various inquiry instruments together. It becomes a hybrid approach when involving narratives and structured processes enabling the adopted instruments to converge to a coherent (living) story. The purpose of Part 2 will be to provide a theoretical framework that with illustration responds to Part 1. Design/methodology/approach Wicked problems and their issues do not respect academic disciplines, and as they are multidisciplinary, they require a cross-disciplinary approach when seeking resolution. Autonomous agency theory is adopted capable of structuring cross-disciplinary inquiry processes and formulating a hybrid inquiry paradigm. The paper sets up a narrative agency approachable of delivering a structure that results in a general theory of hybrid inquiry. Findings The paradigm, which traditionally defines a field of study conceptualises and regulates approaches that enable inquiry into behavioural systems. Mono-disciplinary, they are not suitable for the resolution of issues that arise from cross-disciplinary wicked problems. To resolve this, a relational paradigm has been defined within which sits a cross-disciplinary hybrid inquiry system. A general theory of hybrid inquiry has been offered. It is shown that agency theory can successfully embrace a relational paradigm. Originality/value This paper makes an original contribution by formulating a structured approach on the creation of a relational paradigm capable of supporting hybrid inquiry. It also adopts cross-disciplinary theory to make its case for a relational paradigm, recognising that wicked problems are cross-disciplinary. As part of the regulatory process, it connects Rittel's IBIS schema intended to resolve wicked problems issues and the Johari Window and explains how they would relate. A means is suggested for determining the degree of undecidability of wicked problems issues, and hence, that of the models that inquiry produces. This uses formative characteristics that define a modelling space. The paper also adopts Husserl's concept or lifeworld, which acts as a channel for complex narrative theory through which regulative processes are enabled.
