Using a business model perspective, we identify four continuums relevant for industrial firms making solution business model innovations: customer embeddedness, offering integratedness, operational adaptiveness, and organizational networkedness. Using these continuums, we explore the opportunities and challenges related to solution business models in two different business logics of particular importance in an industrial context: installed-base (IB) and input-to-process (I2P). The paper draws on eight independent research projects, spanning an eleven-year period, involving a total of 52 multinational enterprises. The findings show that the nature and importance of the continuums differ between the I2P and IB business logics. IB firms can almost naturally transition towards solutions, usually through increasing customer embeddedness and offering integratedness, and then by addressing issues around the other continuums. For I2P firms, the changes needed are less transitional. Rather they have to completely change their mental models and address the development needs on all continuums simultaneously.
