+  The more differences there are between your environments, the more likely there will be issues or bugs.
+---
+
+The [harder it is to update an environment][0], the less often it will be done and the more out of sync your environments will become.
+
+The more out of sync your environments are, the higher the chance there will be bugs or issues when changes are moved between environments.
+
+I've had situations where the code I wrote worked for my local database but didn't when moved to staging or production.
+
+I worked at one company where my development database was refreshed nightly, so my site was at most one day out of sync with production.
+
+I knew my code would work with the latest production data and not only the data from days, weeks or months before.
+
+It also meant that I needed to write my changes in an automated and repeatable way so they would be executed on the refreshed database and re-added instead of having to do it manually.
+
+How in sync are your environments and how similar to production is the environment you're testing against?
