If you sort legal offices into three general categories, they shake out like this: In-house corporate counsel, large corporate law firms, and small/medium sized private practices. In many peoples' minds, the most likely LPO early adopters would be the in-house corporate counsels, because the culture of big business has already embraced outsourcing an array of other back office functions. That is, for corporations there is less of a mental shift required to see the value in LPO. Additionally, corporate attorneys already outsource significant amounts of work to outside counsel. Again, no change in worldview required.
Many industry watchers then site the small and midsize firms as the next enthusiastic users of LPO, thanks to the ability of an LPO to provide flexibility, e.g. overnight turnaround, ultra affordable pricing, and scalability to support peek demands on a smaller firm.
The sector that many thought would be the slowest to embrace LPO was the well established, conservative larger firms. The conventional wisdom was that these firms, with their seasonal hiring patterns, established hierarchies, and entrenched billable hours model would be the slowest to evolve based simply on inertia.
So much for conventional wisdom.
The trend that we're seeing take root is that of large firms actively aligning with an LPO to then present their services to corporate counsel in a convergence that benefits each party. The large firm gains an advantage over their competitors with the significant savings the LPO provides; the LPO benefits by the association with well established domestic firms; and the in-house counsel enjoys the dual benefit of cost savings managed by a firm with whom they already have a business relationship.
And it doesn't seem unreasonable to conclude that the driving force behind the trend is the recent financial crunch, which has forced corporate counsel to demand changes from the firms they traditionally hire.
