Paramount Inc. has come up with a new product development project for which

the project manager forms a team. The team includes Asher, Marcus, Tina, and

Alexis from accounting, marketing, manufacturing, and sales divisions

respectively. On completion of the project, the team disperses and the four return

to their original departments. However, each week, the four meet after work on

Thursdays to have dinner at the local diner. The type of team formed by the

project manager for the product development project is an example of $a(n)$ :

task force

informal group

community of practice

self$-$directed team
