- This study explains the constructs of a purchasing portfolio model (PPM) that defence authorities can use in practice in defence procurement and designs a segmentation model. We identify open PPM design and application questions in the literature and conduct a Delphi study with twenty experts from Swedish defence authorities to design a segmentation model that is fit-for-purpose. The paper addresses the open design and application questions discussed in the literature and satisfies the operational requirements of the Swedish Armed Forces (SwAF). The proposed segmentation model builds on three dimensions: the operational requirements of the SwAF, the market's ability to deliver supplies on time, and limitations in the SwAF operational capability if the market does not deliver supplies on time. To reduce complexity, we propose a two-stage model in which we use one dimension as a precursor to a two-dimensional model. In the latter, we merge sixteen elements into one square along with three other segments which users should treat differently. The paper contributes to extant academic knowledge on PPMs by eliciting practitioners' views on open design and application questions. We develop the proposed segmentation model in cooperation with practitioners and believe that it will be of value in defence procurement practice.

Operations planning revisited : theoretical and practical implications of methodology
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Parts of NATO’s contemporary planning framework called the comprehensive operations planning directive (COPD), and parts of the operation-level planning process should be revised since they suffer from methodological inconsistency. This claim is defended by discussing contradicting methodological properties and heuristics applied when framing and managing a military problem in accordance with the COPD. The methodological inconsistency within the COPD; in other words, simultaneously applying contradictory methodological properties, implies one theoretical and three practical implications. The theoretical implication is summarised in a meta-theoretical framework and explained by discussing five methodological properties: non-linearity, emergence, independently changeable generalisations, invariance and boundaries. The three practical implications of methodology imply that methodology is guiding: the problem-frame, conceptual development and action. To improve military planners’ understanding and management of these four identified implications, NATO is recommended to develop a “handbook of methodology.” The purpose of such a handbook should be to emphasise the utility of methodology when planning military operations.

Facebook and Twitter in Crisis Communication : A Comparative Study of Crisis Communication Professionals and Citizens
- 2016
-

Tidskriftsartikel (refereegranskat)abstract
- This mixed-methods study presents a comparative analysis of the use and perceived usefulness of Facebook and Twitter, among Swedish citizens and crisis communication professionals, as crisis communication tools and information sources. The use and per-ceived usefulness of Facebook and Twitter are not congruent and consistent betweenthe two different groups, according to the overall study. Communication professionals, for example, report higher levels of perceived usefulness regarding Facebook’s potential as a crisis communication tool than do the citizens. Taken together, the results show that researchers (within social media and crisis communication) and crisis managers both need to deal with the fact that social media is not a homogenous phenome non with a single coherent role in crisis management and communication research and practice.

Segmentation and differentiation in defence supply chain design : A dynamic purchasing portfolio model for defence procurement
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- An important priority in the current Swedish Defence Bill is to increase the operational warfighting capability of the Swedish Armed Forces, which has implications for the defence supply chain. A recent study suggested that the Swedish Armed Forces should use segmentation of supplies and differentiation of supply chains to enable an affordable supply chain design (SCD). This raises questions regarding which segmentation model and which supply chain strategies (SCSs) the Swedish Armed Forces should use.The purpose of this research is to design and develop a purchasing portfolio model (PPM) for defence procurement, which will be of practical use for defence authorities. The author defines a PPM as consisting of a segmentation model, tactical levers, differentiation strategies and guidance for management decisions. The research builds on a Delphi study with twenty experts from Swedish defence authorities. It addresses the operational requirements on readiness and sustainability that must be satisfied, as well as research gaps and open issues in the literature regarding PPM design and application.The findings include several novelties. The author proposes a dynamic PPM, including an innovative two-stage segmentation model, with a precursor and a two-dimensional model. The latter merges sixteen elements into one square and three other segments. Another originality is that the PPM is both prescriptive and serves as a catalyst for in-depth discussions. The author also develops guidance for management decisions, including twelve tactical levers, and eight SCSs to differentiate treatment of the supply segments.The research contributes to theory by combining constructs from the purchasing and supply management (PSM) literature and supply chain management (SCM) literature, and applying them in the context of military logistics, including defence procurement. It contributes to practice by developing a PPM that is relevant to practitioners in defence procurement and satisfies the operational requirements of the Swedish Armed Forces. It also contributes to methodology by investigating how researchers can use two panels in Delphi studies to enhance research validity.

- PurposeDefence supply chains (SCs) aim at operational outcomes, and armed forces depend on them to provide availability and preparedness in peace and sustainability in war. Previous research has focussed on strategies for SCs aiming at financial outcomes. This raises the question of how suitable commercial supply chain strategies (SCSs) are for supply chain design (SCD) in defence. The purpose of this paper is to explain the constructs of SCSs that satisfy military operational requirements and to propose SCSs that are appropriate in defence.Design/methodology/approachThis paper reports on a Delphi study with 20 experts from Swedish defence authorities. Through three Delphi rounds, two workshops and a validation round, these experts contributed to the reported findings.FindingsThe findings demonstrate that commercial SC constructs are acceptable and applicable in defence but not sufficient. An additional strategy is required to satisfy requirements on availability, preparedness and sustainability. The paper shows that different requirements in peace and war make it challenging to design suitable defence SCs and proposes eight SCSs that satisfy these requirements.Research limitations/implicationsThe results emanate from the Swedish defence context and further research is required for generalisation.Originality/valueThis paper extends theory by investigating SCs aiming at operational outcomes. For managers in companies and defence authorities, it explicates how the unique issues in defence must influence SCD to satisfy operational requirements.

Bokkapitel (refereegranskat)abstract
- Purpose The chapter proposes a model for evaluating environmental information based on informativity as a measurement of whether corporate environmental disclosures provide readers with information relevant for making reasonable assessments of companies’ environmental work. Methodology/approach On a general level, informativity denotes a set of universal principles for information qualities. In order to make informed assessments, information ought to provide readers with information on specific projects, outcome, and long-term impact. The model proposed herein allows researchers and practitioners to quantify corporate environmental information based on a set of key textual variables. By allowing for the quantification of qualitative information, the model allows for comparative studies of CSR communication across, for example, companies, sectors, and nations. Research implications The model is applicable for corporations with an interest to evaluate their performance by applying standardized and set principles. Practical implications The model can be used as a tool for consumers and investors alike in making better and more informed assessments about a corporation’s environmental initiatives and performances. This application is particularly relevant for stakeholders with an interest in developing statistical data for assessing and benchmarking environmental communication. Originality The chapter proposes a model for evaluating environmental information as a measurement of whether corporate environmental disclosures provide readers with information relevant for making reasonable assessments of companies’ environmental work.
