What to Look for in a Contact Center Sentiment Analysis Solution?

1. Would the solution be attuned to sentiments shown inside the contact centers?

Almost all the calls that come into a contact center happen because customers have issues that need to be solved. But it does not mean that ALL the interactions would be negative.

Several contact center sentiment analysis solutions which are operating in the market today are not able to tell the sentiment difference between phrases like - “That was a bad response” and something like “I did not like that response.” The optimal solution would undertake a holistic approach that does not base the sentiment analysis across a single phrase or word and thus would be able to accurately detect negative sentiments of seemingly similar statements.

3. Will there be any manual efforts required?

You will more likely be able to take advantage of the contact center’s sentiment analysis if it is automated. You should look for a completely automated solution that delivers sentiment scores straight to the report or dashboard without calling for a definite manual inspection and documentation.

The right solution will get you the names of the teams, top-performing agents, and groups in the context of sentiments. This, in turn, will help you enable the sharing of best practices and would serve as the indicator of agents or teams who need quality evaluations.

5. Would the system allow a correlation of sentiment score with the other contact center KPIs?

It would also let you integrate the sentiment info with the agent and customer effort score.
