Modern modeling methods are developed in various ways, some following method engineering approaches and principles, others in more ad-hoc ways based on experience, observation, or by exploration of innovative ideas. In all cases, the assessment of the method quality and fitness to the different situations in which it has to serve is a challenge that the method engineers have to face. In this paper, we aim to share knowledge concerning the process of development of modeling methods with an emphasis on systematic approach to verification, validation, and evaluation (VVE). The goal of the paper is to: (1) clarify the differences and key activities and practices of method VVE, (2) to analyze how these have been applied to several modeling methods, and (3) to capture and share key best practices in this process.

While digital leadership is central to digital transformation, its role in information technology operating model (ITOM) renewal has remained unexplained. This paper contributes to the information systems literature by opening the digital leadership black box and disentangling it into the nuances of savvy (SADL) as opposed to sluggish digital leadership (SLDL). It presents an exploratory longitudinal case study of two large companies from two different industries which reveals that SADL drives much more successful ITOM renewal by employing a SIT approach – Speed, Involvement of employees and Timing. The findings demonstrate that having a clear strategy to gain speed, continuous employee involvement and timely seizing of opportunities make a significant difference in ITOM renewal.
