This kind very common, new boss come in gonna bring in his own team and people.
Then next as part of the onboarding process, a consultancy firm will be onboarded to streamline and trim the processes from within. Set some KPI then work it out from there.
But all said, these folks probably have no experience in the business and neither do they care about the company structure. They'll just achieve the KPI stated at all any cost without thinking about the long run of the company.
End up, only the CON-sultancy firm will conclude the exercise, then say cannot achieve cause you all didn't follow what we have proposed.
Guess will take another 5 years to clean up the mess.
