The proposed solutions for sustainable development generally require new links and the involvement of multiple sectors. As a consequence, organizations can rely less on closed and rational analysis-based forms of strategizing; they increasingly see the need for joint strategy processes. However, a joint strategy process challenges the boundaries of the organizations involved, which creates tensions. This paper takes stock of conflicts and uncertainties that organizations which become involved in joint strategizing encounter. Our focal point is the sustainable development of infrastructure. We focus on an explorative single case study on the coordination of heat infrastructure development in the Regional Energy Strategy Rotterdam-The Hague (RES R-TH). The primary data were collected via three sources of information: observations from roundtable meetings, interviews with representatives of the organizations involved in the RES-TH and reflections from participants of these actors in research-led ateliers. We illuminate a wide range of tensions between organizations and identify three categories of dilemmas: input, throughput and outcome. By explicating dilemmas and identifying categories, we discard the idea that a universal solution exists for organizations engaging in joint strategizing. Instead, we provide evidence of different types of decision-making challenges, which emerges from a more granular analysis of the open strategizing process.@en

Brede aandacht voor duurzaamheid stelt nieuwe eisen aan infrastructuren in Nederland. De opgaven gaan over de grenzen van verschillende sectoren, denk alleen al aan mobiliteit en woningbouw enerzijds en energie anderzijds. Dit vraagt om nieuwe strategische overleg- en besluitvormingsstructuren. Infrastructuurplanning krijgt daarmee ook een ander, opener karakter. In de kern van dit vraagstuk opereren de infrastructuurbeheerders, die een nieuwe verbindende positie krijgen. In dit artikel worden drie verschillende nieuwe strategieprocessen gepresenteerd en geanalyseerd. De precieze vorm en focus van de nieuwe overleg- en besluitvormingsstructuren zullen zich in de komende jaren ontwikkelen. Inzicht in deze strategieprocessen en in het bijzonder de rol van infrastructuurbeheerders vergroot kennis hoe en in welke mate openheid ruimte kan bieden aan meer integrale afwegingen en synergie. @en
