The shift from locally operated software to subscription models is usually described from the user organisation's point of view. For the consulting side it is at least as far-reaching.
For decades two pillars carried the business: long-running rollout projects with a high share of custom programming, and running the systems in the partner's own data centre. Both lose substance once operation and updates sit with the vendor and the standard deliberately leaves little room. Instead of project volume, what now counts is advisory quality, process knowledge and the ability to keep extensions cleanly outside the core.
For companies in the middle of a selection process this is a useful test. Asking a prospective partner how much revenue comes from customisation, and where extensions are technically placed, reveals more about the coming years than any reference list.
