  We have explored some phenomenological issues during calculations of
transport coefficients for hadronic matter, produced in the experiments of
heavy ion collisions. Here, we have used an ideal hadron resonance gas model to
demonstrate the issues. On the basis of dissipation mechanism, the hadronic zoo
is classified into resonance and non-resonance members, who participate in
dissipation via strong decay and scattering channels respectively. Imposing our
phenomenological restriction, we are able to provide a rough upper and lower
bound estimations of transport coefficients. Interestingly, we find that our
proposed lower limit estimation for shear viscosity to entropy density ratio is
little larger than its quantum lower bound. By taking a simple example, we have
demonstrated how our proposed restriction help to tune any estimation of
transport coefficients within its numerical band, proposed by us.
