Power BI for SMEs: what it is and when it makes sense

What Power BI is, in one sentence

Power BI is Microsoft's tool for connecting data from several sources (ERP, Excel, databases) and turning it into a dashboard that refreshes itself, instead of being rebuilt by hand every time. Nothing more exotic than that. It isn't artificial intelligence, it doesn't replace anyone, it's a connector and a calculation engine with a visual layer on top.

The confusion usually comes from how it's sold, as if it solved the underlying problem on its own, when really it only automates the part of building the report. If the underlying problem isn't solved (messy data, nobody agreeing on which source is the right one), Power BI just builds a nice-looking dashboard on top of a problem that's still there.

Who it genuinely makes sense for

It makes sense when there's already a specific report someone rebuilds by hand every month or every week, using data that comes from systems that already exist. The more manual that process is today (copying and pasting between spreadsheets, exporting from an ERP, cross-checking by hand against another sheet), the faster the difference shows.

It also makes sense when several people need to see the same number and today each of them has their own version, because each one starts from a different copy of the same file.

Who it doesn't make sense for, yet

If nobody in your company regularly builds any report (there's no recurring dashboard, no figure several people need to see the same way), Power BI doesn't solve anything, because there's nothing to automate yet. The manual process it would replace needs to exist first.

It also doesn't make sense if the source data is so messy that nobody trusts it. Connecting an unreliable source to a dashboard doesn't make it more reliable, it just gets the wrong number there faster, with better design.

What needs to exist before you start

Three things, in this order:

A specific report with a name. Not "improve data visibility" in general, but Monday's sales report, the monthly close, open-order tracking.

Sources identified and accessible. Knowing where each figure comes from today, even if it's a spreadsheet one person maintains. If nobody can say for certain which is the correct source, that's the first problem to solve, before touching Power BI at all.

Someone to maintain it afterward. A dashboard nobody checks when something stops adding up is worse than the old spreadsheet, because it looks automatic and no longer is.

What Power BI doesn't do on its own

It doesn't clean messy data. It doesn't decide which metric matters. It doesn't replace the conversation of defining, once, what each figure means for everyone in the company. All of that is upfront work, and it's what actually determines whether the project succeeds or turns into a nice dashboard nobody looks at three months later.

What to do with this

If you have a specific report that's already done by hand and the sources exist, even if they're messy, Power BI can make sense, but the tool is the easy part. What determines whether it works is everything before it, that is, which report, with what data, maintained by whom.

I automate exactly this kind of project, with whatever tool you already have (Power BI or anything else). The first meeting is one hour, free of charge. It's there to see whether it makes sense in your case before you commit to anything.
