Professional Services Automation (PSA) is like a big toy box for companies that provide services. It helps them keep track of all the different toys (or tasks) they need to do and how long they're taking to do them. It's also like a big map that helps them find the toys they need to work on next.
Let's say your mommy does makeup for people's faces. She has lots of toys to keep track of, like the different people she needs to see, the makeup she needs to bring, and how long it will take her to do their makeup. PSA helps her keep all of this organized, so she knows which toy to take out of the toy box first.
PSA also helps mommy make sure that she is making money from doing these makeup jobs. It helps her keep track of how much time it takes to do each makeup job and how much money she is earning from each job. This way, mommy can make sure she is making enough money to buy more toys for you and your siblings.
Overall, PSA helps companies that provide services be more organized, efficient and profitable. It's like a big toy box that helps them keep track of all the toys they need to play with to make money.
