Many  companies  are  struggling  to  navigate  in  the  rapidly  changing  environment  and uncertain time of the digital era. Previous research has been exploring the ongoing trend of digital transformation, as well as digital business strategies, but still there is little guidance for  practitioners  in  terms  of  concrete  frameworks  and  concepts  for  digital  business strategizing.  This  thesis  investigates  critical  factors  of  digital  business  strategizing  and contributes  by  developing  a  maturity  model  for  digital  business  strategizing.  The contribution  of  this  study  is  two  folded,  on  the  one  hand  it  provides  practitioners  a conceptual  artefact  in  order  to  analyze  their  challenges  in  the  new  landscape  of  digital transformation and on the other it gives valuable insights for researchers on the new rising phenomena of digital business strategies.
