Let me begin, as I always do, with some straight talk. The legal industry is facing a moment of profound change. If you’re a partner at a law firm thinking AI won’t fundamentally alter your business model, I’ve got news for you – you’re wrong.
Recent research from Deloitte suggests that 39% of legal jobs could be automated in the next two decades (Deloitte, 2023). A Stanford Law School study found that GPT-4 already outperforms junior lawyers on certain analytical tasks (Stanford Law School, 2023). The McKinsey Global Institute estimates that 23% of a lawyer’s job could be automated with current technology, with that percentage increasing as AI capabilities advance (McKinsey, 2022).
But this isn’t necessarily a catastrophe. It’s an opportunity – if you know how to position your firm correctly.
The legal sector has historically been resistant to change. Remember when email was going to destroy the profession? Or when online legal services would make lawyers obsolete? Neither happened, but both did require adaptation. AI represents a more fundamental shift, and law firms need a structured approach to navigate it.
The Three Horizons Model, developed by McKinsey, provides exactly that framework. It helps organizations manage their present business while simultaneously preparing for future transformation. For law firms facing AI disruption, this model offers a practical roadmap.
The Three Horizons Model: A Primer for Law Firms
The Three Horizons framework divides strategic thinking into three time-based perspectives:
- Horizon 1 (H1): Your core business today – the bread and butter of billable hours, existing clients, and traditional legal services
- Horizon 2 (H2): Emerging opportunities that extend your current business model – think technology-assisted legal services
- Horizon 3 (H3): Transformative business models that might seem radical today but could become mainstream in the future
The model isn’t about abandoning your core business. It’s about managing all three horizons simultaneously, with different expectations, metrics, and resources for each.
As Harvard Business Review research shows, companies that successfully manage all three horizons are 2.4 times more likely to achieve above-average profit growth (Harvard Business Review, 2021). For law firms, this translates to maintaining profitable traditional practices while developing capabilities that will matter in an AI-transformed legal landscape.
Horizon 1: Optimising Your Current Legal Practice
Horizon 1 represents your firm’s core services and clients that generate most of your current revenue. The objective here isn’t radical transformation but improving efficiency and quality through selective AI integration.
Tactical Approaches for H1
Document review and due diligence: AI tools can review contracts and legal documents at speeds impossible for human lawyers. A study by JPMorgan showed their COIN program could review commercial loan agreements in seconds rather than the 360,000 hours previously required by lawyers and loan officers (Financial Times, 2022). Law firms should identify repetitive document-heavy processes and implement AI solutions to enhance efficiency.
Legal research: Tools like LexisNexis and Westlaw have incorporated AI to dramatically improve search capabilities. Research from the American Bar Association shows that firms using advanced legal research tools reduce research time by up to 70% (ABA, 2022). Firms should invest in training lawyers to leverage these tools effectively.
Predictive analytics for case outcomes: Companies like Lex Machina and Premonition use AI to analyze historical case data and predict litigation outcomes. Their research indicates that lawyers using predictive analytics have 30% better settlement outcomes (Lex Machina, 2022). Firms should consider how these tools might improve client advice and litigation strategy.
The key metric for Horizon 1 initiatives should be efficiency gain – how much more productive are your lawyers with these tools? Research from Thomson Reuters indicates that firms effectively implementing legal tech solutions see a 30-40% increase in lawyer productivity (Thomson Reuters, 2023).
Horizon 2: Developing New AI-Enhanced Legal Services
Horizon 2 is where firms extend their current expertise into adjacent areas, particularly through AI augmentation. These initiatives might not generate significant revenue immediately but position the firm for future growth.
Strategic Approaches for H2
Productized legal services: Traditional law firms bill by the hour, but AI enables the creation of fixed-price legal products. A great example is Wilson Sonsini’s automated document generator for startup financing. Research from the Corporate Legal Operations Consortium shows that 76% of corporate clients prefer fixed-fee arrangements, suggesting substantial market demand (CLOC, 2022).
Legal operations consulting: As clients implement legal tech, they need guidance. Law firms can leverage their combined legal and technological expertise to advise on legal operations transformation. PwC research indicates the legal operations consulting market is growing at 25% annually (PwC, 2023).
Collaborative human-AI service models: Rather than viewing AI as a replacement, develop service models where AI handles routine aspects while lawyers focus on high-value work. MIT research demonstrates that human-AI teams outperform either humans or AI working independently in complex problem-solving (MIT, 2022).
Horizon 2 initiatives should be measured by new client acquisition and revenue growth in these emerging service areas. According to Thomson Reuters, firms with robust legal tech capabilities grew revenue 5.6% faster than competitors in 2022 (Thomson Reuters, 2023).
Horizon 3: Reimagining the Legal Service Model
Horizon 3 explores potentially transformative business models that might seem speculative today but could become mainstream in the future. This is where law firms should be most experimental and forward-thinking.
Transformative Approaches for H3
AI-driven predictive compliance: Imagine systems that continuously monitor regulatory changes and automatically update corporate policies to ensure compliance before problems arise. Research from Stanford’s CodeX center suggests predictive compliance could reduce corporate regulatory violations by up to 60% (Stanford CodeX, 2023).
Legal intelligence platforms: Beyond just search, these would combine multiple data sources to identify patterns invisible to human lawyers and suggest novel legal arguments or strategies. Early research from Michigan State University Law School indicates such systems can identify winning legal arguments overlooked by experienced lawyers in 30% of complex cases (Michigan State Law, 2022).
Smart legal contracts: Blockchain-based contracts that automatically execute when conditions are met could transform transactional law. Research from the International Association for Contract & Commercial Management suggests smart contracts could reduce contract disputes by up to 90% (IACCM, 2023).
The challenge with Horizon 3 initiatives is that traditional ROI metrics don’t apply. Instead, measure progress through learning objectives – what insights are generated, what capabilities are developed, and what positioning advantages are secured. According to McKinsey, companies that allocate at least 10% of innovation resources to Horizon 3 initiatives are twice as likely to outperform industry peers in long-term growth (McKinsey, 2022).
Managing All Three Horizons Simultaneously
The true challenge isn’t developing initiatives for each horizon – it’s managing them simultaneously within a single firm. Different horizons require different mindsets, metrics, and management approaches.
Resource Allocation
Research from the Innovation Advisory Board suggests a resource allocation of approximately 70% to Horizon 1, 20% to Horizon 2, and 10% to Horizon 3 (Innovation Advisory Board, 2022). This ensures the core business remains funded while creating pathways to future growth.
For a typical law firm, this might translate to:
- 70% of technology budget for systems that enhance current practice
- 20% for developing new AI-enhanced service models
- 10% for experimental initiatives that might transform the practice entirely
Organisational Structure
Different horizons may require different organizational structures. Research from London Business School indicates that Horizon 1 activities thrive in traditional hierarchical structures, while Horizons 2 and 3 benefit from more agile, multidisciplinary teams (London Business School, 2022).
Some approaches that have proven effective:
Innovation committees: Cross-functional teams with representatives from legal practice, technology, and business development to evaluate and champion initiatives across horizons.
Legal innovation labs: Dedicated units that can operate with different metrics and approaches from the core business. Allen & Overy’s Fuse program and Dentons’ Nextlaw Labs are examples that have generated significant returns.
Strategic partnerships: Collaborations with legal tech companies, universities, or even clients. Research from Harvard Law School shows that such partnerships accelerate innovation and reduce risk (Harvard Law School, 2022).
Implementation: A Practical Roadmap for Law Firms
Let’s translate this theoretical framework into practical steps for law firms facing AI disruption:
1. Conduct an AI Vulnerability Assessment
Before implementing the Three Horizons approach, understand your firm’s exposure to AI disruption:
- Which practice areas involve routine, process-driven work most susceptible to automation?
- Which services deliver the highest value through uniquely human skills like empathy, judgment, and creativity?
- What percentage of firm revenue comes from potentially automatable work?
Research from the American Bar Foundation found that practice areas like document-heavy M&A due diligence, real estate transactions, and certain aspects of litigation support are most vulnerable to AI disruption (American Bar Foundation, 2023).
2. Develop a Three Horizons Portfolio
Based on your assessment, create a balanced portfolio of initiatives:
Horizon 1 (Immediate Implementation)
- Identify 3-5 opportunities to enhance current services with AI
- Allocate resources for lawyer training on AI tools
- Develop metrics to measure efficiency improvements
Horizon 2 (12-24 Month Implementation)
- Explore 2-3 AI-enhanced service offerings
- Establish cross-functional teams to develop these offerings
- Set clear milestones for development and commercialization
Horizon 3 (Exploratory)
- Allocate resources for monitoring transformative technologies
- Establish partnerships with legal tech innovators
- Create learning objectives rather than traditional ROI metrics
3. Align Skills and Talent Strategy
To implement your Three Horizons portfolio, you’ll need new skills. Research from the Corporate Executive Board indicates that successful digital transformation requires a 40% skills change in most organizations (CEB, 2022).
For law firms, this means:
Technical literacy: All lawyers need sufficient understanding of AI to identify opportunities and limitations. According to the ABA, only 35% of lawyers report adequate technical literacy for today’s practice (ABA, 2023).
Data science capabilities: Either through hiring or partnerships, firms need access to data science expertise. Research from MIT shows organizations with dedicated data science capabilities are 3x more likely to succeed in AI initiatives (MIT, 2023).
Change management skills: Partners and practice leaders need to drive adoption of new technologies and approaches. A Deloitte study found that 70% of digital transformation failures stemmed from resistance to change rather than technical issues (Deloitte, 2022).
4. Create Governance and Decision-Making Processes
Each horizon requires different decision-making approaches:
Horizon 1: Traditional ROI and efficiency metrics work well Horizon 2: More flexible stage-gate processes with learning milestones Horizon 3: Venture capital-style approaches focused on option value
Research from BCG shows that applying traditional approval processes to all horizons reduces innovation success rates by up to 80% (BCG, 2022).
Common Pitfalls and How to Avoid Them
In my consulting work with professional service firms, I’ve observed several common failures in applying the Three Horizons approach:
The “All or Nothing” Fallacy
Some firms either ignore AI completely or attempt radical transformation overnight. Both approaches fail.
Research from the Legal Executive Institute shows that firms making incremental, strategic investments in legal tech outperform both technology laggards and those making massive, unfocused investments (Legal Executive Institute, 2022).
The “Technology First” Trap
Many firms start with technology rather than client needs. They purchase expensive AI systems without clear use cases.
A better approach is to identify specific client problems or internal inefficiencies, then find appropriate technologies. According to Gartner, organizations that start with business problems rather than technology solutions are 2.5x more likely to report successful digital transformation (Gartner, 2023).
The “Partner Consensus” Delay
Law firms’ partnership structures can slow decision-making to the point where opportunities are missed.
Research from Columbia Law School shows that firms with dedicated innovation governance – separate from partnership votes on every initiative – implement twice as many successful legal tech initiatives (Columbia Law School, 2022).
Conclusion: Beyond Survival to Strategic Advantage
AI disruption in the legal industry isn’t just about survival – it’s about strategic advantage. The firms that thrive will be those that use the Three Horizons approach to simultaneously:
- Optimise current services with selective AI implementation
- Develop new AI-enhanced service models
- Explore transformative approaches that reimagine legal service delivery
This doesn’t mean abandoning the core values of legal practice – judgment, ethics, and client service will remain essential. But the delivery mechanisms and business models will transform.
As Harvard Business School professor Clayton Christensen noted in his research on disruptive innovation, the organizations that thrive through disruption are those that cannibalize their own business models before competitors do it for them (Harvard Business School, 2022).
For law firm leaders, the Three Horizons framework offers a structured approach to doing exactly that – maintaining the valuable aspects of traditional practice while creating pathways to a transformed future.
The evidence is clear: AI will change legal practice fundamentally. The choice for law firms isn’t whether to respond, but how. Those that implement a balanced Three Horizons approach won’t just survive the AI revolution – they’ll lead it.
