Even though its adoption is moving from the early stage to mainstream, many organisations are still afraid that their resilience might deteriorate because of the additional levels of abstraction that CC introduces. This additional complexity makes the assessment of ICT operational resilience more difficult and no consensus exists of such analysis. Following a multi-method approach, this research proposal first extends prior research in the field, looking at new possible categories of resilience-oriented requirements when working in CC environments. Based on the results, this research will propose a conceptual model that helps organisations to maintain and improve Organisational Resilience (OR) when working in CC environments, from the ICT operational perspective. Particularly, as a lack of coordination has been identified as one of the main problems when facing disruptive incidents, using coordination theory, this research will identify the fundamental coordination processes involved in the proposed model. The results of this research should be of interest to academic researchers and practitioners.

This model introduces several advantages compared with traditional environments along with typical outsourcing benefits reshaping the ICT services supply chain by creating a more dynamic ICT environment plus a broader variety of service offerings. This leads to higher risk of disruption and brings additional challenges for organisational resilience, defined herein as the ability of organisations to survive and also to thrive when exposed to disruptive incidents. This paper draws on supply chain theory and supply chain resilience concepts in order to identify a set of coordination mechanisms that positively impact ICT operational resilience processes within cloud supply chains and packages them into a conceptual model.

This sourcing model is reshaping the ICT services supply chain by creating a more dynamic environment with various levels of service needed and a broader range of providers offering alternative value propositions making it larger and more complex. This leads to a higher risk of disruption and brings additional organisational resilience challenges. Organisational resilience defined herein as the ability of organisations to survive and also thrive when exposed to disruptive incidents. This thesis adopts a qualitative research design to investigate how ICT resilience activities can best be coordinated across a cloud supply chain. Based on existing supply chain resilience theories and considering specific characteristics of cloud supply chains, it proposes and empirically validates a conceptual model as a tool for guiding efforts to maintain and improve resilience in cloud supply chains. The model is based on existing supply chain management and supply chain resilience theories and identifies a set of coordination mechanism that positively impact ICT resilience processes within this chain. The empirical findings suggest the value of the model in terms of structuring the organisational resilience conversation across cloud supply chains.

Even though its current adoption is moving away from the early stage to the mainstream, many organisations are still concern about the additional levels of abstraction that cloud environments introduce. Particularly, this additional complexity represents a hurdle in the assessment of ICT readiness for organisational resilience, and no consensus exists yet for its analysis. Based on a literature review of cloud computing reference architectures, and organisational resilience and business continuity frameworks, this paper suggests a framework to guide research into this field from an operational perspective.
