Bad Data Kills Great Finance Professionals
Your adrenaline is pumping and you’re up next to present your numbers to the senior management team. You’ve been working so hard to get to this point and you know there are no two chances with these senior executives. This is it.

Having good data and solid calculations are the backbone of every good finance professional. With each mistake you make you lose credibility and will need to make up for it and that typically takes a lot longer than it would’ve taken to prevent the mistake from happening in the first place. Your manager or your team might be able to overlook simple mistakes from time to time but you can be certain that senior management will not. No matter how great of a finance professional you are if you can’t get the basics of good data right your bad data will kill you.
