Is team work productive
No its not
Of course. Things get done quicker and with higher quality if you work as a team.
More times than not.
From the perspective of someone who constructs hiking trails in the wilderness, I can say that team work is extremely productive. Experience tells me that 4 chainsaw operators is vastly more productive than one chainsaw operator.
yes it is when im in a group im the leader and i WiN
Even Messi and Cristiano Ronaldo needs his own team.
Honestly, it just depends on what you're doing. To be blunt: Teams are around to do what you cannot do alone. In areas such as my math class, I have few peers. This is a fact. Therefore, it is not beneficial to me to work in a team, and more often than not I don't. When I do things with Boy Scouts, we work in small teams to train younger scouts, build lashing structures, etc. When playing baseball, we use a larger team, so we can win. So really it all depends on the circumstances and objectives.
