How do I know if my data is “good enough”?

The Short Answer

Your data is good enough when it reliably answers the few questions you actually need to make decisions. You are not aiming for perfect or complete; you are aiming for accurate enough to trust and relevant enough to act on. If your numbers consistently point you toward better choices, they are doing their job.

Perfect Data Is a Myth

No business has flawless data, and chasing it is a way to avoid making decisions. The real question is not "is this perfect?" but "is this good enough to act on with confidence?" A few reliable numbers that you actually use beat an elaborate system you never look at. Aim for useful, not pristine.

Start From the Decision, Not the Data

Good-enough is defined by the question you are trying to answer. If you want to know which channel to invest in, you need reasonably accurate source data on your customers, not a complete picture of everything. Work backward from the decision: what is the smallest set of trustworthy numbers that would let you choose well? That is your bar.

Check for Trust and Consistency

Data is good enough when it is captured the same way each time, free of obvious errors, and consistent enough that the trend is real rather than noise. You do not need precision to three decimals. You need to trust the direction the numbers point and the relative size of the differences they show.

Improve It Where It Matters

When a number you rely on feels shaky, tighten how you capture that one thing rather than overhauling everything. Targeted improvement keeps your data honest where decisions actually depend on it, without drowning you in administration.
