World of sports
IN ENGLISH, THE BUSINESS WORLD DRAWS SIGNIFICANT INSPIRATION FROM THE WORLD OF SPORTS, WHICH IS REFLECTED IN MANY COMMONLY USED EXPRESSIONS. WE HAVE COMPILED A LIST OF OVER 130 SUCH EXPRESSIONS, COMPLETE WITH EXPLANATIONS AND EXAMPLES.
GET INTO THE FULL SWING OF THINGS.

This expression is used when describing a person, team, initiative, or process that has finished its ramp-up period and is now running smoothly at the expected pace.
It comes from the world of sports, especially those that involve a swinging motion to hit a ball - such as golf, baseball, or tennis. Originally, it referred to the moment when a player, after a more erratic period, begins to hit the ball consistently and with precision. That is when we say they have "gotten into the full swing of things."
Examples of usage in a professional context:
After the holidays, it took a few days to get back into the full swing of things.
Usually, it takes a new employee a few weeks to get into the full swing of things.
The ad campaign started slowly, but after a few changes, we are getting into the full swing of things.
