Is that to improve the situation for SMEs in particular? This is probably outside my very narrow areas of expertise. What I would think would be the easiest priority but probably harder to discover in practice is looking at the kinds of obstacles to the health of SMEs that have other problems with them.
If there is—and it's an if—overregulation of certain elements of the housing market, if approvals are too difficult for small contractors to make inroads, those are the kinds of things that probably make sense in their own right but will also promote the health of SMEs.
Discovering those sorts of things would be the ideal, but that's easy to say and it's probably harder to cover things that don't serve a useful purpose and are easily changed.
