Two week sprints is not water-scrum-fall. Water-scum-fall is when you do your waterfall SDLC in sprints. So your BA team does 4 analysis sprints then hands over to the architecture team who do 4 architecture sprints. then they hand over to the UI design team to do 3 UI design sprints Then you tender for a development partner in 4 procurement sprints. Then the development partner joins you and does 10 development sprints before they hand over to the UAT team who do 8 UAT sprints while the Dev team does 8 fix sprints. Then the project team hands over to Ops who do 2 deployment sprints. And then after its deployed Ops does 8 test/fix sprints to fix the hundreds of defects you knowingly deployed to production with. That's water-scrum-fall and it is the most common way to develop software today in big corporates working with big professional services firms. This is what you typically see when big corps claim to be doing agile. this or SAFe.
