This study aims to compare the predictive capability of two popular software reliability growth models (SRGM), say exponential growth and inflection S-shaped growth models. We first review the exponentiated Weibull (EW) testing-effort functions and discuss exponential type and inflection S-shaped type SRGM with EW testing-effort. We then analyzed the actual data applications and compare the predictive capability of these two SRGM graphically. The findings reveal that inflection Sshaped type SRGM has better prediction capability as compare to exponential type SRGM.
