What does deficiency state means?

Answer 1

Sounds a bit redundant, but:

definition of deficiency:

1. [n] the state of needing something that is absent or unavailable; "there is a serious lack of insight into the problem"; "water is the critical deficiency in desert regions"; "for want of a nail the shoe was lost".

2. [n] lack of an adequate quantity or number; "the inadequacy of unemployment benefits".

Without context, it is difficult to answer more exactly. Sorry!
