Guidance for the application of a dynamic purchasing portfolio model for defence procurement – A Swedish perspective

Abstract

Purpose: The purpose of this paper is to develop guidance, including tactical levers, for the application of a dynamic purchasing portfolio model (PPM) for defence procurement.

Design/methodology/approach: The study uses a workshop and a literature review to identify suitable tactical levers for the application of a dynamic PPM for defence procurement. Based on application rules proposed in previous research (Ekström et al., 2021), the study then formulates guidance for application and validates the methodology in two desktop exercises.

Findings: The study identifies tactical levers and proposes guidance for the application of a dynamic PPM for defence procurement.

Research limitations/implications: The proposed guidance includes tactical levers, which will enable defence authorities to dynamically reposition in the segmentation model proposed by Ekström et al. (2021) and find an enhanced position to optimise. The presented results build on a study in the Swedish defence context. To determine generalisability, additional studies are required.

Originality/value: The paper develops guidance, including tactical levers, for the application of a dynamic PPM for defence procurement, which is original in several aspects. The guidance addresses public procurement, which is a novelty. In contrast to most extant PPMs, the model is dynamic, which enables practitioners to reposition in the model.

Keywords: Purchasing portfolio model, tactical levers, guidance for application, defence procurement, military logistics.

Paper type: Research paper.
