This paper presents the results from a Delphi study in which the researchers modified the design to enhance rigour. The study indicates that research design may influence the results of Delphi studies. Furthermore, the study suggests that there may be limitations to conventional designs, and possibilities with modified designs.

ABSTRACT
Layered resilience has received increased attention in recent years. This paper addresses an important subset of layered resilience, which is resilience in defence supply chains. The paper reports on findings from two studies, conducted in the Swedish defence sector. The purpose of the two studies is to identify feasible solutions for how the Swedish defence sector can redesign its supply network to meet the new challenges of a re-established Swedish Total Defence. The first study used a modified Delphi technique and concluded that two Delphi panels constitute a useful modification to the Delphi technique. Two panels increase the validity of the results and can potentially lead to interesting outcomes that a traditional design is less likely to produce, particularly if combined with presenting the panels with statements from different perspectives and using workshops to discuss the findings. The second study used a survey to investigate which tactics for resilience in defence supply chains defence authorities and defence industry prefer in peace, crises, and war. Though inconclusive, the findings indicate that authorities and companies agree that multiple sourcing and pre-storage of supplies are important tactics to achieve resilience in defence supply chains. This is in line with previous research in commercial supply chains, which identifies increased safety stock and multi-sourcing as two of the most commonly used tactics to address disruptions.
