Forecasting excuses


Recently, I was chatting with a fellow CFO about the things required to build financial projections for a company.

This person shared a belief that's highly common among finance folks:

To do any kind of financial forecasting, you first need to build a solid financial operations foundation.

The thinking goes...

If you don't have excellent data on what's historically happened within the company,

  • Then how could you EVER hope to possible predict what will happy in the future?
  • What could you possibly base predictions based on?
  • How could you ever feel confidence in your forecasts?

But here's the thing:

I don't 100% agree with this way of thinking.

Why?

Because it IS important...

...But it can also be an excuse.

"How could I ever predict what will happen in my startup if I don't have any data?"

Excuse.

"I couldn't possibly provide any reports to the CEO until the accounting team closes the monthly books!"

Excuse.

"It's impossible to track my project profitability because I don't have good data on time spent per project!"

EXCUSE!

Here's the truth:

When it comes to financial data, you will nearly always deal with some degree of imperfection, unknowns, and mess.

If you're waiting for perfect financial records to make business decisions based on data,

You're never going to actually get around to doing it.

If you need to drive decisions based on imperfect or incomplete data, the answer is simple:

Use reasonable assumptions & estimates, label carefully, and update regularly.

That's how you use the data you have to get to the place you need,

Rather than wish for the data you don't have,

And get no where in the dark.

Often, when I'm called in to help a new client, they aren't 100% sure what's broken. Sure, they may have theories, But often, the only thing they know for sure are the symptoms of a problem. The problem itself is still a little unclear. "We don't have enough revenue to hit our next milestone with investors." Isn't specific enough to be actionable; Are you not charging enough per seat? Are you not discoverable in the market? Are you targeting the wrong customers? Are you losing customers after...

As a startup leader, it can be incredibly challenging to balance time spent being strategic vs. executing. In particular, when you’re entering a new market or pivoting or evolving your product. Spend too much time on execution, and you’ll get no where fast. Spend too much time on strategy, and you’ll get no where slowly. How do you know you’ve reached the perfect balance? Be strategic for long enough to know which questions you should be asking your market. Then execute until you’ve answered...

As anyone with bad knees will tell you (🙋🏻♀️), Downhill is not always easier. The same applies to resumes. When hiring, we often look for impressive titles, big brands, and upward career progressions. We associate these with competence and with success. But here's the thing: That's not what those titles signify. Those titles only tell us what other folks have thought about a candidate in the past. Those titles show the opportunities this candidate has been given by others. Those titles tell...
