Part one
Why a good report is not the same as good reporting
Power BI Desktop is where most organisations start. Someone connects to
a data source, cleans the data, builds a model, drags a few visuals onto
a page, and produces something genuinely useful. That first report often
works very well.
The problems begin later, and they are rarely about the visuals. The
report lives on one person's laptop. Refreshing it depends on that
person. Three colleagues ask for the same view with a slightly different
filter, so three copies appear. Finance quotes a margin figure that
differs from the one in operations, because the two reports were built
from different extracts with different assumptions. Then the analyst
changes role, and the file no longer has an owner.
For organisations in the Netherlands and across Europe, this becomes
visible as reporting requirements grow. Finance, operations, sales,
supply chain and management teams all depend on consistent information,
and increasingly they also need to explain where that information came
from. A report that works beautifully on one person's computer can
become a maintenance burden the moment several teams depend on it.
This is where the relationship between Power BI Desktop and Power BI
Service matters. They are not competing products or interchangeable
options. They are two halves of one reporting process, and most of the
pain organisations experience comes from treating only the first half as
a project.
The pattern we see most often
A single analyst builds genuinely strong reports in Power BI
Desktop. Adoption spreads. Within a year there are dozens of files,
several overlapping datasets, no clear ownership, and a recurring
internal debate about which number is correct. Nothing is broken
technically. The reporting environment simply grew without any of
the decisions that make growth manageable.
The fix is almost never a different tool. It is a different
sequence: agree what the measures mean, build the model once, design
for the decisions the reports support, then publish with access,
refresh and ownership planned from the start.
Who this guide is for
This is written for business leaders, operations managers, finance and
reporting owners, and IT decision makers who already have some Power BI
in place or are about to invest in it. It is deliberately light on
syntax and heavy on the decisions that determine whether reporting
becomes an asset or an overhead. Where a technical choice matters, we
explain why it matters rather than how to click through it.
If your organisation is based in the Netherlands and reports across
multiple entities, currencies or business units, the governance and
refresh sections will matter more than the modelling sections. If you
are at the start of the journey, read them all in order.
