Item Open Access How to outsource agile projects effectively(Taylor and Francis, 2022-01-06) Aoufi, Abdelkader; Schoeman, Magnus; Turner, NeilOverview: Faced with a rapidly changing business environment, organizations are increasingly turning to Agile project management to deliver innovation programs. Deployment of Agile poses specific challenges, often because the required skills, measures, and management behaviors differ greatly than those of traditional project management. When faced with a need to outsource Agile project delivery to a third party, organizations often apply contractual approaches developed for traditional “waterfall” projects, which prove unsuitable. This study investigated the perspective of client-side advisors in Agile projects when delivery is outsourced to a third party. Client-side sourcing advisors are an important component of the Agile delivery ecosystem because clients often rely on advisors’ experience when scoping out and procuring digital transformation projects.Item Open Access Performance evaluation of single and cross-dimensional feature detection and description(Institution of Engineering and Technology (IET), 2019-10-18) Kechagias-Stamatis, Odysseas; Aoufi, Abdelkader; Richardson, Mark A.Three-dimensional local feature detection and description techniques are widely used for object registration and recognition applications. Although several evaluations of 3D local feature detection and description methods have already been published, these are constrained in a single dimensional scheme, i.e. either 3D or 2D methods that are applied onto multiple projections of the 3D data. However, cross-dimensional (mixed 2D and 3D) feature detection and description has yet to be investigated. Here, we evaluated the performance of both single and cross-dimensional feature detection and description methods on several 3D datasets and demonstrated the superiority of cross-dimensional over single-dimensional schemes.
