The 31-year-old was handed the leadership reins again, taking over from Shan Masood, and will skipper the team later this month with a two-Test series against West Indies in the Caribbean.
Pakistan finished bottom of the WTC table in the previous cycle and lost away to Bangladesh and have not won an away Test series since July 2023.
Babar previously led Pakistan in 20 Test matches with a record on 10 wins and four being drawn while suffering six defeats.
Speaking in an in-house PCB interview, Babar said: "It is an honour for me to be leading Pakistan again. I have learned from my past experience of leading the side and playing as a player.
"I am very confident this time and I feel I have improved and matured. So, I will be leading this team with better planning and a positive mindset this time around.
"There were negatives and positives in my last tenure, which I analysed and it provided me clarity.
"My main focus is on discipline, fitness, and performance and there would be no compromise on them. They are of utmost importance for me to build this team.
"I have always backed the players whenever I have led the team, but that can only be done when there is a positive response from the players."
The Pakistan squad have been in a month-long summer camp at the National Cricket Academy in Lahore to prepare the side for the upcoming tour, with a particular focus on raising fitness levels.
"What I have realised over the years is that we have been lacking a bit in fitness in Test cricket because of which we did not have impactful performances with the bat or ball," Babar said.
"Through one-on-one discussions with the coaches and the management, the players were made aware about why they were not able to perform in critical situations and that exercise helped us zero in on fitness.
"We have also worked on our fielding during the camp and learned how to survive adverse conditions, as this camp was conducted in scorching heat."
Pakistan batter Babar Azam has been chosen to replace Shan Masood as Test captain with the Pakistan Cricket Board hoping a change in leadership will help them get to the next level.
Pakistan head coach Mike Hesson says he wants to develop multiple leaders in the national team so that the actual captain will have support when in the field.
Australia Women star Ellyse Perry wrote another chapter in her storied career by almost single-handedly guiding her side to an 113-run win over Pakistan at the ICC Women's T20 World Cup.
The Proteas Women revived their ICC T20 World Cup campaign with a two-wicket victory over Pakistan in their Group A encounter at Edgbaston on Wednesday.
