Implementing Gibbs (1988) reflective cycle into UX design [on hold]

I would like to raise a discussion here, if you think it is a good idea to implement Gibbs (1988) reflective cycle into you UX design as part of common practice within the company.

Personally I believe that GRC is a great tool for UX design testing.

What are the reasons not to use Gibbs reflective cycle in UX design based on academic literature or companies' practices?
