How many times have you seen the new manager come into their role and systematically deconstruct and change everything that was built before them?
Sometimes this is required. But not always.
I cannot remember where I first learned it, but there is a saying in brand management that “a new friend can be a brands worst enemy“. In brand management constant reinvention destroys value – as consistency with a brand over time is how it establishes its meaning.
As a new manager, you need to try to find an unbiased way of identifying what is good and working vs. what is clearly not and needs to be improved. Build on the first, and fix or eliminate the latter.
Use caution in your approach. Just because you did not develop it, doesn’t mean its wrong. Just because it’s not ‘perfect’, doesn’t mean it should be changed.
