  Conventional Software Management Conventional software management often refers to older, more rigid methodologies, typically characterized by sequential, document-driven processes like the Waterfall model. Key characteristics include: Emphasis on planning: Extensive upfront planning and documentation. Sequential phases: Progress flows linearly through distinct phases (requirements, design, implementation, testing, deployment). Big bang integration: Components are integrated at later stages, leading to higher risk. Late discovery of issues: Problems often found late in the lifecycle, making them costly to fix. Evolution of Software Economics Historically, software development was largely a cost center with unpredictable outcomes. Early days: High hardware costs, low software costs. Focus on optimizing code for limited resources. Shift: As hardware costs dropped, software complexity grew, making software development the dominant cost. Crisis: The "software crisis" high...
