Key Takeaways
  • Agility is not about being small — it is about being appropriately sized for core demand while having rapid access to additional capacity
  • The core-flex model is emerging as the dominant structure for mid-to-large in-house legal teams
  • Technology is the enabler of agility: without the right systems, flexible models create administrative overhead that offsets the benefits
  • Agile teams consistently outperform traditional structured teams on both cost and satisfaction metrics

In today's fast-paced business environment, legal teams must be more agile than ever. The ability to quickly adapt to changing priorities, scale resources up or down, and access specialised expertise on demand has shifted from a competitive advantage to a baseline requirement for in-house teams that want to remain relevant and well-funded.

The Core-Flex Model Explained

The most effective modern legal teams are adopting a "core-flex" structure: a permanent core team sized for baseline workload, supplemented by flexible resources that scale with demand. This is fundamentally different from the traditional model where headcount tracks peak demand and creates structural over-capacity during troughs.

  • Core team: Senior leadership (GC/CLO), practice leads, and key operational roles. Sized for 70–75% of average workload.
  • Flex layer: Experienced independent contractors and secondees, engaged for specific periods or projects. Covers peak demand and specialist needs.
  • Extended network: Specialist external counsel for genuinely complex or jurisdiction-specific matters.

Organisational Design Principles

Right-size the permanent core

The most common mistake is making the permanent core too large. This drives costs up during low-demand periods and creates the illusion of capacity that actually discourages efficient use of external resources. A lean, high-quality core is consistently more effective than a larger, mixed-quality team.

Invest in onboarding infrastructure

The operational success of a core-flex model depends entirely on how quickly and effectively flexible resources can be integrated. Invest in standardised onboarding documentation, matter templates, and access protocols so that a new contractor can be productive within their first day.

Teams that invest in onboarding documentation and systems report flexible contractors reaching full productivity within 2 days on average, compared to 3–4 weeks for those with ad hoc processes.

Technology as the Enabler

Agile legal teams cannot function effectively without the right technology infrastructure. Matter management systems, document repositories, communication tools and timesheet platforms must all be accessible to flexible team members with appropriate permissions and security controls.
