The company builds its product on a different technical architecture from the incumbents it competes with (how data, compute, tenancy or components are arranged), and that arrangement delivers a benefit customers can see: speed, scale, cost, fewer upgrades, sharing or collaboration. An incumbent can match the benefit only by rebuilding its product, not by adding a feature.
How Novel Architecture works
Incumbents' products, organizations and customer installs are built around the old arrangement, so matching the benefit means a rebuild that strands their existing base (Henderson & Clark's architectural innovation). The lead lasts as long as that rebuild takes.

Innovation: the warehouse rebuilt for the cloud, storage separated from compute
What it did
Two Oracle database architects wrote a SQL warehouse from scratch to run only as a service: many compute clusters over one shared copy of data, no tuning, vacuuming or statistics (2012; paper 2016)

What architectural choice differs from the incumbents', what customer benefit does it deliver, and what would an incumbent have to rebuild to match it?

Architectural innovation
Note. The benefit must be one customers experience and the incumbent must be shown lacking it; a new tech stack with no customer-visible difference does not count. When both the company and its rival adopted a new architecture against older incumbents, the tag does not separate them (Tableau vs Qlik). Business-model differences the incumbent will not copy are Counter-positioning; tag both when both apply. Owning more layers of the stack is Vertical Integration Strategy. A newly available platform the company rides (the iPad, the browser, the cloud) is Enabling technology shift in the Arena; tag this only for what the company built on it that rivals did not.
