A methodology for project portfolio selection under criteria prioritisation, uncertainty and projects interdependency – combination of fuzzy QFD and DEA

© 2018 Elsevier Ltd Resources of an organisation (people, time, money, equipment, etc) are never endless. As such, a constant and continuous challenge for decision makers is to decide which projects should be given priority in terms of receiving critical resources in a way that the organisation's productivity and profitability is best guaranteed. Previous literature has already developed a plenitude of project portfolio selection methodologies ranging from simple scoring to complex mathematical models. However, most of them too often fail to propose one integrated and seamless method that can simultaneously take into account three important elements: (1) prioritisation of selection criteria over each other, (2) uncertainty in decision-making, and (3) projects interdependencies. This paper aims to fill this gap by proposing an integrated method that can simultaneously address all these three aspects. The proposed method combines Quality Function Development (QFD), fuzzy logic, and Data Envelopment Analysis (DEA) to accounts for prioritisation, uncertainty and interdependency. We then apply this method in a numerical example from a real world case to illustrate the applicability and efficacy of the proposed methodology

Continuous business case usage in the context of a strategic IT enabled investment at Rabobank

It has been argued that optimal value creation from IT enabled investments requires a business case that is used throughout the entire investment lifecycle, as opposed to an approach that terminates when the investment is formally approved. This approach requires a rational transformation in the perspective on business cases in which they need to become a living document that is frequently updated and matures along the investment. This study presents the business case process for a strategic IT enabled investment at Rabobank. The case site was specifically selected for being a high-performer in the area of continuous business case usage. This case study shows how a high-performer operating in an IT intensive industry makes use of a continuous business case approach during a strategic IT enabled investment and the benefits they perceive from it.</jats:p
