I'm part of a high performing team, and for the last few years we have been delivering high quality output while hardly increasing our team size.
We have a sister team that is, to put it politely, not as high performing. They have been struggling to deliver even though the have almost twice as many engineers.
Last year we got some headcount to grow our team, but leadership decided to shift it to our sister team, since they had problems reaching their goals (you know, the squeaky wheel gets the grease). This was fine with us since we weren't in a particular hurry, and we would pick up the headcount later.
Fast forward and we have a hiring freeze, meaning that our sister team was able to grow headcount, while we can't grow ours.
The double whammy? since we don't have as many people as we expected, we couldn't pick up projects that were in our roadmap. Guess who got those projects instead? our sister team.
Morale of the story? do a shit job and you will be rewarded with bigger teams and more scope, which in turn will translate into promotions and bonuses.
