The method uses the reflective items as a criterion measure to establish the validity of the formative(More)

It is this simultaneity that we refer to as IT adoption ambidexterity, and recognize as an area in need of research. Based on prior research on organizational ambidexterity, this(More)
As the complexity of outsourcing projects increase so do the risks of failure. Firms strive to control those risks with more structured development methods, which impose an overhead on the project and reduce flexibility. There is evidence that agile methodologies are able to deliver better results in the current dynamic environment. While such methodologies(More)
