  In the present paper, we discuss the role of gravitational decoupling to
isotropize the anisotropic solution of Einstein's field equations in the
context of the complete geometric deformation (CGD) approach and its influence
on the complexity factor introduced by L. Herrera (Phys. Rev. D 97, 044010
(2018)) in the static self-gravitating system. Moreover, we also proposed a
simple and effective technique to generate new solutions for self-gravitating
objects via CGD approach by using two systems with the same complexity factor
and vanishing complexity factor proposed by Casadio et al. Eur. Phys. J. C 79,
826 (2019). The effect of decoupling constant and the compactness on the
complexity factor have been also analyzed for the obtained solutions.
