“…With this development of NHPP as the base, several methodologies have been coming into existence which includes Gompetz [5], S-shaped Distribution [6], [7] and Inversed S-Shaped distribution [8]. Particular models like Jelinski and Moranda model [9], Littlewood & Verrall model [10], Goel -Okumoto model [11], Musa -Okumoto model [12], Kuo, Huang, & Lyu [13], Brown DB [14], Kapur PK [15], Khan, Ahmad and Rafi [16], Ohishi, Okamura and Dohi [17], Satya Prasad, Naga Raju and Kantam [18], Zou and Davis [19], Kiyoshi, Henrik and Poul [20] etc., are also highlighted in the literature with the aim, optimizing the errors in the developed software's. However, these, models are effectual when the errors are estimated most apparently and have a complete overview of discriminating between failure and non-failure.…”
