Know the details, use small teams and break large landscapes into small contracts. Don’t be chased away by fears of complexity of management.
In order to apply appropriate methods then you need to think small. You can’t treat the entire system as one thing but you need to break it into components. I will often extend this to using small contracts localized around specific components. Knowing the details helps you manage a landscape. But you can take this further and even use small teams such as cell based structures. Probably the best known approaches to using small teams are Amazon’s Two Pizza model and Haier’s Cell based structure. page
