The third edition of the Next Gen ATP Finals featured the following innovations:

-    Wearable Technology In-Competition

• For the first time on the ATP Tour, players were permitted to use wearable technology in competition during the Next Gen ATP Finals. The data collected allowed players and coaches to quantify the demands of the competition, better understand athlete loading and make key performance decisions that are supported with objective data.

-    Shorter Format: First to Four games sets (Tie-Break at 3-All), Best-of-Five sets, with No-Ad scoring

• Shorter set format designed to increase number of pivotal moments in a match, while the best-of-five set format does not alter the number of games required to win a match (12) from the traditional scoring format, and No-Ad scoring.

-    Shorter Warm-Up

• Matches begin precisely four minutes from the second player walk-on.

-    Shot Clock

• A shot clock was used in between points to ensure strict regulation of the 25-second rule, as well as during set breaks, Medical Time-Outs, and the four-minute countdown from the player walk-on to the first point of the match.

-    Medical Time-Outs

• A limit of one medical time out per player per match.

-    Player Coaching

• Players and coaches communicated at certain points in the match, providing additional content and entertainment value for broadcast. Coaches will not be allowed on-court.

-   Towel Rack

• Players were instructed to use a towel rack at the back of the court to remove the onus on ball kids to handle towels.

-   'Free Movement' Policy

• A ‘free movement’ policy was applied to the crowd (except behind the baselines) throughout the tournament. The policy enabled fans to move freely in and out of the stadium during matches, providing a relaxed fan-friendly atmosphere and ensuring fans were not restricted entry into the stadium at any time.

-   Video Review

• Video review was available – and utilised – to further analyse judgement calls from the chair umpire, including the following incidents: double bounces; foul shots, such as a double hit or a carry; touches – when the ball might skim a racquet or clothing; and invasion – when the player, or anything he's wearing or carrying, makes contact with the opponent's side of the court while the ball is in play. Players were able to challenge any such calls.
