The three sizes
What is the impact, and what will it take to build?
Every initiative gets sized on those two things before anything else is discussed. We use the same three words on every engagement, so a conversation about scope never turns into a conversation about vocabulary.
Sand, pebbles and rocks. It is our own shorthand, and it holds up because it sorts work by what actually decides the cost of owning it: how much has to be built, and what kind of person has to be around afterwards. Everything we do falls into one of the three, and most departments end up with a mix.
Sand
Small initiatives the team builds for itself
Contained improvements built by the people who actually do the work, with an expert beside them for guidance and nothing required from your technology team. They live inside the tools the team already has, so there is nothing new to host, licence or support, and nothing to keep alive once the session ends.
The impact of any single piece is modest. The point is that there are many of them, they compound across a department, and once the team has watched a few get built they start making their own.

Pebbles
Light systems that live somewhere and need light upkeep
Something that runs on its own, which means it has to live somewhere: a flow in your Microsoft tools, a small app on your intranet, a shared workspace, a scheduled task that keeps a dashboard current. It does need maintaining, but not by a specialist. A capable person on the business team can restart it, adjust a threshold or edit a rules table, and your technology team is involved lightly or not at all.
Built in weeks rather than months. The impact is usually a whole step of a process rather than a single task.

Rocks
New systems that need technical specialists for as long as they run
A genuinely new system: an application, a build against another system's developer tools, a digital team member owning a role across several systems and writing into them under governed rules, or a data platform with history and anonymization. Built over a few months, typically two to four, then monitored, patched and evolved for the life of the thing by people who do that professionally.
The impact is the largest of the three, and so is the commitment. That is exactly why the second question has to be answered before a rock is started rather than after. Some rocks are run once, under supervision, to clear a problem that then no longer exists.
