Software Execution Models

There is no "One True Way" to build software. The model you choose determines the problems you will face.

The Models

• Waterfall: The default for physical engineering, often misused for software.
• Agile: The dominant religion, often reduced to "micro-management with standups".
• Hybrid: The reality for 90% of enterprises.
• V-Model: Essential for safety-critical systems (Auto, MedTech).

How to Choose

Do not choose based on what is trendy. Choose based on your Cost of Failure.
