Improving your 401(k) plan and other seemingly minor aspects of your business is important if you’re determined to build an exceptional company, instead of one that’s merely average.

“An exceptional company is one that gets all the little details right,” Virgin founder Richard Branson said in an interview with Inc. That requires listening to your employees and acting on their feedback. “The people out on the frontlines know when things are not going right. If you listen to them, you can soon improve all those negative things.”

At the same time, it’s easy to have a mediocre 401(k) plan. Set up a plan, hold an annual trustee meeting and call it a day. In a mediocre plan, there’s no attention to detail: no ongoing monitoring or resolving the many issues that arise during the year, and no ongoing education for the plan’s participants to make sure they’re getting the most value from their retirement benefits.
