If you are exploring Kannan vs scrum, you’ve already failed before you even started. First, what you are trying to do? Is it a big ambitious multi year project or even mid size which has a lot of modules? Then first you need to assemble a core team - PM, PO, Architect, Sr Engineer - and get the core components built to some extent or laid out clearly, before trying to find a suitable development strategy. In scrum, you should be ‘only’ integrating components and not developing, just like the assembly line.
