'not enough' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'implement a change of title' is the wordplay.
'implement' becomes 'tool' (tool is a kind of implement).
'a change of' is an anagram indicator.
'title' anagrammed gives 'ittle'.
'tool'+'ittle'='TOO LITTLE'

'to' is the link.

Can you help me to learn more?

(Another definition for too little that I've seen is " insufficient".)
