$$ Discuss the key challenges that an enterprise faces during transformation such as growth, value, and focus and how these challenges shape the systems engineering process. Examine how transformation frameworks in systems engineering manage change by addressing both external pressures such as market shifts and internal dynamics, such as business processes and value streams. Critically examine case studies such as Amazon and Wal$-$Mart, which utilized transformation to redefine their industries, and consider how other enterprises can utilize these lessons to their own transformation efforts.
