How Does a Power BI Project for SMEs Actually Work?

In the previous article we talked about the 5 indicators every SME should have on its dashboard. The question that follows is almost always the same: "ok, but how does this actually work in my company?"

There's no mystery and no magic. A Power BI project for SMEs follows a predictable path, with clear stages and short timelines. The goal is simple: move from scattered data to a dashboard that helps you decide better.

1. Data source diagnosis

Before designing any dashboard, you need to understand where the data lives and what state it's in. In a typical SME, that usually means spreadsheets scattered across several departments, an ERP or invoicing system, maybe a CRM, and some manual records.

Nothing gets built at this stage. The focus is on identifying what exists, what's reliable, and what needs reorganizing before it can feed the dashboard.

What the company needs to prepare: access to the main sources, such as the ERP, invoicing system, and control spreadsheets. No advance cleanup is needed.

2. Choosing the right indicators

With the sources mapped, the next step defines what the dashboard will show. Not all 5 indicators from the previous article make sense for every company, and there's often one additional, sector-specific indicator worth tracking.

The criterion is always the same: the metric has to change a decision. If a number doesn't change what someone does on Monday morning, it doesn't belong on the dashboard.

The output of this stage should be a short list of indicators, with each formula written down to avoid ambiguity later on.

3. Connecting and cleaning the data

This is where the technical work begins: connecting the sources to Power BI, handling inconsistencies, and building the data model behind the dashboard. This is the stage where you find, for example, customer names spelled differently, categories that need standardizing, and dates in different formats.

How long this stage takes varies a lot with the quality of the sources. A well-structured ERP saves days compared to a set of spreadsheets maintained by different people over the years.

4. Building the dashboard

With the data cleaned and connected, the visual build itself is fast. The goal is a dashboard any manager can read in 30 seconds, with no technical training.

That means large numbers, colors that highlight what's out of the ordinary, and no decorative charts that don't answer real questions. There are usually one or two iterations with the people who'll use the dashboard day to day, to adjust what makes the most sense to see first.

5. Validation and delivery

Before the dashboard goes live, the numbers are checked against the values the company already uses as a reference, such as the month's total revenue. Only once everything matches is the dashboard ready for use.

Delivery also includes a short session to show how to navigate the dashboard and use the filters. You don't need to know Power BI to use it day to day.

How long it takes

For a dashboard with the 5 fundamental indicators, the actual work usually runs 2 to 4 days. The factor that most affects the timeline isn't the number of indicators: it's the quality and dispersion of the data sources.

Once built, the dashboard updates automatically and is accessible on any device, without depending on exporting and cleaning Excel files every week.
