Once upon a time in the sprawling kingdom of , a master architect named Ali Bahrami noticed a crisis. The kingdom’s builders were exhausted; every time they wanted to build a new castle, they started from scratch, carving every single stone by hand.
Bahrami begins his analysis by critiquing conventional functional decomposition. In traditional structured methods (e.g., Waterfall, SA/SD), the focus is on processes or functions that transform data. Data and actions are treated as separate entities. This separation leads to several problems: data specifications are often global and vulnerable to unintended side effects; changes in data structures ripple through multiple functions; and the system's structure mirrors the flow of control rather than the real-world entities. Bahrami notes that this approach becomes brittle as system size increases, leading to the "software crisis" of high costs, missed deadlines, and low maintainability. object-oriented systems development ali bahrami ppt
