As the VP of HR at Microsoft, I saw a lot of people make mistakes. From simple math on their expense accounts to serious errors in judgment that required the local police to resolve. Also, much of what I learned about handling mistakes at work came from an enormous mistake I made years ago.

Everyone makes mistakes, but at work, it seems like they hit harder.

On the job, consequences often warrant more than simply, "Oops, my bad." Mistakes at work often cost a lot of money and might put jobs at risk — even your own. Here are the three steps you should take to help save your job or even career when you make an error at work: own it, fix it, and prevent it.

Own it

The first step to resolving an error at work is to take responsibility for the mistake. If you made the error, don't deflect, don't blame the computer, don't pretend it didn't happen. Own it.

Tell your boss as soon as possible before things spiral out of control.

For example, many years ago, I wrote the copy protection code for Foxpro, the database software that was eventually sold to Microsoft. I tested it on dozens of machines in every case I could find.

The very day we released a beta version, it froze the receptionist's computer — not just crashed it, but locked it up so the machine couldn't even boot. I quickly discovered it was my code that had caused it, and we had just sent that code to thousands of testers.

My code could've locked up dozens or hundreds of customer computers.

I realized my error wasn't that complex, so I immediately enlisted the help of all of my peers to discover the extent of the problem and potential fixes. My friend in shipping stopped the copies that had not been sent, and my colleague sent a message to every beta tester not to install the software. For some users, it was too late, so I quickly developed a tool to recover the frozen machines.

By the end of the day, I had a fix for the receptionist's machine that we could apply worldwide. We posted those steps as quickly as we could.

I survived the error with the help of my friends.

On the other hand, in very rare cases, the mistake is very serious, even potentially illegal. If you think what you've done exposes you or the company to legal liability, get some protection. It might be a good idea to consult a personal attorney right away.

Fix it

Often the best thing to do when you've made a mistake is to repair the damage. Correct the report and let everyone know it's been fixed. Clean up the mess on the shop floor. Make an adjustment entry to the inventory.

As a manager later in my career, I very much appreciated people who could say, "Hey, I broke this thing, but don't worry, I've already fixed it.

Whatever the mistake, a key part of owning the problem is fixing it. If the damage is out of your hands or beyond your abilities, at least understand and explain it as best you can. You are uniquely positioned to know how it got broken, that knowledge can go a long way to fixing the problem. So tell that part of the story too.

Also, it's never a good idea to fix things and hide them, pretending they didn't happen. Not only is that not true, but it has many negative effects. If your mistake is later discovered, the trust relationship you have with your boss is gone — maybe irreparably. Mistakes can be forgiven, but untrustworthiness is harder to repair.

There may have even been side consequences to your mistake that you didn't see, which could ripple far and wide. That glitch in the inventory could result in distrust of the inventory system overall and lead to far broader issues.

Prevent It

That leads us to the next step: stopping it from happening again.

As the person who made the error, you have a unique view of how similar mistakes can happen. You can provide insight into ways to prevent them.

In my case, I worked to ensure we had a broader selection of test machines and developed a new set of test cases for all our security code. I was probably the only one who understood the impact of my mistake and was the best one to implement changes.

Work with your manager to identify ways to prevent the error. Maybe it's as simple as a checklist. Perhaps more than one person needs to review it. Maybe there needs to be software or physical locks to prevent the possibility of the mistake again.

The one thing we all learn early on is to learn from our mistakes.

A mistake at work doesn't have to end your career

In my case, the error that I owned and fixed certainly didn't slow my career. Not long after, I was promoted to development manager for the company. I'm sure my transparency and ownership were part of the reasons I was trusted for that role.

When you make a mistake, the best way for the entire company to learn from it is for you to own the mistake, fix it, and work to prevent it from ever happening again.
