Question
What is Input /Process/Output (IPO) approach in S/W Design.
Answer
The IPO approach strictly models every software subsystem as a black box receiving inputs, mathematically processing them, and generating outputs.
The Input-Process-Output (IPO) approach is a fundamental, rigorous structural modeling paradigm. It demands that the engineer mathematically break down the software into distinct, isolated modules. For every single module, the engineer must explicitly define the exact raw data entering it (Input), the specific algorithmic transformation applied (Process), and the precise resulting data (Output).
