Why Solution Hygiene Saves Time and Money

In Dataverse projects, and in IT projects in general, cleaning up has a problem: there is no direct customer for it. A new field has a sponsor, a cleaned-up naming convention does not. That is why it usually only happens once the pain is big enough.

That is understandable, but an expensive approach. Not because untidy solutions run worse technically, but because every future change takes longer, and that speed is the crux of the matter.

Where the time is actually lost

The biggest item is searching. Whoever changes a field first has to find out where it is used: in which forms, views, scripts, flows and reports. With documented components and consistent naming, that takes minutes. Without both, it becomes half an hour, and uncertainty remains at the end.

The second item is caution. If nobody knows what a field is for, it does not get deleted. So it stays. And because it stays, it has to be taken into account during the next redesign. That way the scope keeps growing without anyone ever having made a decision.

The third item occurs only once, but hard: the handover to new people. A team that inherits an undocumented solution needs weeks for what would take days with documentation.

What can be measured

More than you would think is already in the export. The documentation level, for example: if fifteen out of a hundred custom fields have a description, the knowledge about the other eighty-five lives in people's heads. Or the prefixes: if your own components are spread across three naming prefixes with similar shares, three teams have been building side by side here; more on that in choosing publisher and prefix. Add to that the web resources that nothing points to anymore, see finding dead components, and the stock of classic workflows or old JavaScript.

None of these numbers is a verdict. But together they are a reliable indicator of how expensive the next change will be.

Where cleaning up is not worth it

Not every legacy item has to go. A solution that will be replaced in 18 months does not need to be fully documented. A field that has been working untouched for 5 years is not a risk.

Priority goes to whatever can cause damage while it is left lying around: delete privileges that are too broad, cascading delete rules in places where nobody expects them, outbound connections without encryption. The most common of these patterns are described in security issues in Dynamics 365 solutions. Next comes whatever stands in the way of a concrete plan: before a migration, there is simply no way around the superseded technologies.

Everything else I would attach to existing work. The table is being rebuilt anyway? Then describe the fields in the same go. That costs only minutes. A cleanup campaign of its own costs a budget that, in my experience, nobody approves.

The practical starting point

The first step is not cleaning up but measuring. As long as nobody knows the state of a solution, every discussion about it is a matter of opinion. With numbers you can at least lay out honestly what comes first.
