New-generation managers are increasingly populating organizations' management. They consist of digital natives who grew up with Information Systems (IS) and digital immigrants who learned to engage with IS as adults. Today, such managers have to make faster decisions than in the past and find themselves more and more in mobile IS use situations. These requirements combined with managers' ability to use IS themselves result in the need for self-service Management Support Systems (MSS). This article develops a more business-driven design for such MSS. In doing so, we propose both a rigorous set of requirements and initial design guidelines to start further discussion. The utility of these guidelines is demonstrated with a "mobile-first" prototype on a modern business intelligence platform: the Corporate Navigator app.
