Financial impact of employee tenure
The correlations of manager tenure (+0.44) and crew tenure (+0.26) with profits show that there is a clear positive financial effect of increasing tenure. Though both factors have a quite strong correlation with profits, the manager tenure seems to be a much stronger driver.
However, considering the learning curve of the employees it seems reasonable to assume that the impact of tenure depends also on the tenure itself. In other words, employees would be increasing their contribution much more at the beginning of their careers than once that they acquired all the core skills needed. One way to contemplate this effect into the analysis is replacing the tenure by its corresponding square root. The comparison of the linear and the non-linear models shows that the non-linear model fits better.
