Let the system be defined as a set of N number of elements, E.
So,
E={e_1,e_2,…,e_n} … (i)

Let a newly discovered issue, to resolve which it requires to change ith element which is tightly coupled only with jth element.
and,
coupling(e_i,e_j,∆_i )∷work(∆_1 e_1,∆_2 e_2,…,e_i,…,∆_i e_j,…,∆_n e_n) … (ii)
To reduce technical debt and side effects, l new elements are introduced through Dependency Injection and other technology that makes the already existing ith and newly introduced l number of elements independent.
So,
cohesion(E,∆)∷E{e_1,e_2,…,e_n,e_(n+1),…,e_(n+l)} … (iii)

N.B. New technology with higher efficiency reduces human effort.
