Three project management approaches—traditional, agile, and hybrid—were considered in this study. Results from an international study, including 477 cross-industry projects, indicated that 52% of ...projects could be categorized as hybrid approaches. A regression analysis using multiple outcome measures indicated substantial explanatory power (0.21 < R
2 <0.41). Analysis suggested that hybrid and agile approaches significantly increase stakeholder success over traditional approaches while achieving the same budget, time, scope, and quality outcomes. Hybrid approaches were found to be similar in effectiveness to fully agile approaches. Results validate decisions by practitioners to combine agile and traditional practices and suggest that hybrid is a leading project management approach.
In recent years, many researchers have been conducted on batteries' health monitoring and prognostics, mainly focusing on the batteries' state of charge (SOC). Accurately estimating the state of ...health (SOH) and predicting the remaining useful life (RUL) of battery components are very important for the prognosis and health management of the overall battery system. However, due to the non-linear dynamics caused by the electrochemical characteristics in batteries, the accurate estimations of SOC, SOH and RUL prediction are still challenging and many technologies have been developed to solve this challenge. This paper reviews and discusses state of the art in SOC and SOH and RUL estimation techniques for all battery types. A novel framework is developed and presented to compare all battery techniques based on three dimensions: battery performance (Z dimension), approaches (X dimension), and criteria (Y dimension) to fulfil. All studies are reviewed and discussed based on the dimensions and the criteria defined in the framework. Based on this investigation, this study summarizes at the end the key outcomes and suggests future research challenges.

The importance of IT projects and their impact on critical business processes has increased in recent years. A successful project is therefore an important goal in the client-consultant relationship. ...Current research shows that the fitness of a project management approach determines the overall success of a project, which makes the evaluation in the beginning of a project even more crucial. Consultancies and companies alike face the challenge of finding the right project management approach to guide IT transformation projects at an early stage. This research aims to bring transparency to the decision-making process of evaluating a project management approach based on an explorative study. Experienced experts from the consulting side were interviewed to facilitate an understanding of which factors are the most important to consider in this process. Our findings suggest that the decisive factors are client characteristics in terms of Agility Expertise, Flexibility or Security Need, Openness to Change and Governance Structure, in combination with project settings, like the rigidity of scope, budgeting model or project lifecycle status.
