Comparing CLOC’s Core 12 and ACC’s Legal Operations Maturity Model: A Practical Assessment
• 08 Aug 25
“The CLOC and ACC legal operations models sound great in theory-but how many legal teams actually have the resources to implement them? Something more useful is needed for the predominant legal department out there - small, overworked and under resourced. So, we built out our Model and it has proved effective and empowering every legal team - regardless of size and resources.”
Introduction
In the evolving landscape of legal operations, frameworks like the Corporate Legal Operations Consortium's (CLOC) Core 12 and the Association of Corporate Counsel's (ACC) Legal Operations Maturity Model 2.0 have emerged as pivotal guides.
These models aim to enhance the efficiency and effectiveness of legal departments, offering a structured approach to legal operations. Indeed, if you search Google - seem to be the only model out there - but how relevant are they to your average legal team that is short on resources in the face of growing workflows?
However, while they serve as useful organizational frameworks, they are often unrealistic for the majority of legal teams, particularly those operating with limited resources. The reality is that most in-house legal teams do not have the luxury of a dedicated legal operations function, and expecting these teams to fully implement either model is wishful thinking at best.
This article compares the two models, highlighting their strengths and weaknesses, particularly in the context of real-world constraints faced by legal departments with limited resources. It goes on to introduce the GLS Legal Ops model - a model built to reflect the nuanced realities of the legal department and which any legal team no matter its size or restore status can utilise to drive safe, effective and measurable change .
Note though - this blog is not meant to be critical of the intention behind the ACC and CLOC models - their initiatives, for their qualified audiences, are helpful. However, in our view, the applicability of these models to most in-house legal teams is where they fall seriously short.
Who Are CLOC and ACC?
CLOC (Corporate Legal Operations Consortium)
◼️CLOC is a global community of legal operations professionals, focused on defining and advancing legal operations as a discipline. It brings together corporate legal professionals, legal tech providers, and industry experts to improve efficiency, business integration, and innovation in legal departments.
ACC (Association of Corporate Counsel)
◼️ACC is a leading global association for in-house counsel, offering resources, benchmarking tools, and best practices for corporate legal departments. It focuses on helping legal teams optimize their operational maturity and align legal strategy with business objectives.
Overview of CLOC’s Core 12 and ACC’s Legal Operations Maturity Model
CLOC presents these as essential building blocks for a modern, efficient legal department. The model focuses on legal operations as a distinct function that integrates business principles into legal service delivery.
CLOC’s Core 12 defines twelve key competencies essential for an optimized legal operations function. These focus on building a structured, business-driven legal team:
1. Business Intelligence - Using data and analytics to drive legal decision-making.
2. Financial Management - Managing legal budgets, cost control, and resource allocation.
3. Firm & Vendor Management - Developing efficient relationships with outside counsel and legal vendors.
4. Information Governance - Handling data management, security, and compliance with regulatory requirements.
5. Knowledge Management - Organizing legal knowledge and internal expertise for efficiency.
6. Organization Optimization & Health - Structuring legal teams for maximum efficiency and effectiveness.
7. Practice Operations - Managing workflows, legal service delivery models, and process improvements.
8. Project/Program Management - Applying project management principles to legal matters.
9. Service Delivery Models - Evaluating alternative legal service providers and technology solutions.
10. Strategic Planning - Aligning legal strategy with corporate objectives.
11. Technology - Leveraging legal tech to improve processes, automation, and collaboration.
12. Training & Development - Upskilling legal teams and ensuring ongoing professional development.
ACC’s Legal Operations Maturity Model 2.0
ACC’s maturity model provides a structured way for legal teams to benchmark their progress in different operational areas.
Unlike CLOC’s competency-based approach, ACC’s model uses progressive stages (Early, Intermediate, Advanced) to measure legal operations maturity.
1. Change Management and Communications - Improving stakeholder engagement and legal change management.
2. Contract Management - Optimizing contract lifecycle processes and automation.
3. eDiscovery - Managing litigation readiness and data retrieval processes.
4. External Resources Management - Enhancing relationships with outside counsel and vendors.
5. Financial Management - Controlling legal spend and demonstrating value.
6. Information Governance - Establishing policies for document management, security, and compliance.
7. Innovation Management - Implementing new technologies and process improvements.
8. Intellectual Property Management - Streamlining IP tracking and rights protection.
9. Internal Resources Management - Structuring legal team talent, succession planning, and workload distribution.
10. Knowledge Management - Capturing legal knowledge for operational efficiency.
11. Metrics & Analytics - Using KPIs and benchmarking for legal performance.
12. Project & Process Management - Applying operational best practices to legal matters.
13. Strategic Planning & Legal Operations Leadership - Developing long-term legal strategy.
14. Technology Management - Assessing and integrating legal tech solutions.
Key Differences Between the Models
While both models aim to enhance legal operations, they differ in several key ways:
1. Conceptual Approach
◼️CLOC’s Core 12 is competency-based, offering a broad overview of the essential functions of legal operations without defining how these should develop over time.
◼️ACC’s model is a staged maturity framework, helping teams assess their current level and map out specific steps for improvement.
2. Scope of Coverage
◼️CLOC’s model focuses heavily on legal service delivery, financial management, and operational efficiencies, making it well-suited for teams looking to optimize specific functions.
◼️ACC’s model includes additional competencies such as Innovation Management, Change Management, and Intellectual Property Management, reflecting a broader view of legal operations beyond efficiency.
3. Practical Usability
◼️CLOC’s model is a strong starting point for teams new to legal operations, as it outlines the fundamental components needed for a successful function.
◼️ACC’s model is more useful for established legal ops teams, as it provides a structured progression roadmap that assumes a certain level of maturity.
A specific focus on criticism of the CLOC Model:
◼️Excludes eDiscovery - Lacks a key competency despite its growing importance in legal operations.
◼️Assumes Unlimited Resources - Unrealistic for most legal teams that lack dedicated legal ops professionals.
◼️Overemphasis on Data - Prioritizes business intelligence and analytics, which may be impractical for smaller teams.
◼️Competency Overlap - Areas like Knowledge Management and Information Governance create redundancy.
◼️No Prioritization Guidance - Offers no roadmap on which competencies to focus on first.
◼️Ignores Change Management - Fails to address cultural and behavioral barriers to legal ops adoption.
◼️One-Size-Fits-All - Designed for large-scale legal teams, making it difficult for smaller teams to implement
A specific focus on criticisms of the ACC model:
The Association of Corporate Counsel's (ACC) Legal Operations Maturity Model serves as a framework for legal departments to assess and enhance their operational efficiency. However, several criticisms have been identified:
◼️Resource-Intensive Implementation: Achieving higher maturity levels often requires significant investments in technology, personnel, and process improvements, which may not be feasible for smaller legal departments.
◼️Leadership Skepticism: Some organizational leaders may question the value added by legal operations initiatives, leading to resistance in adopting the model's recommendations.
◼️Resistance to Change: Implementing the model necessitates changes in established workflows and practices, which can encounter resistance from staff accustomed to traditional methods.
◼️Lack of Qualitative Metrics: The model has been critiqued for focusing more on tactical aspects rather than strategic outcomes, resulting in insufficient actionable intelligence for executives. Today's General Counsel
◼️Variable Maturity Across Functions: Legal departments often exhibit uneven maturity levels across different operational areas, making it challenging to apply a uniform model effectively. wolterskluwer.com
◼️Overemphasis on Compliance and Financial Management: The model tends to focus heavily on compliance and financial management, potentially overlooking other critical areas like innovation and technology adoption. wolterskluwer.com
These criticisms suggest that while the ACC's model provides a structured approach to legal operations, its applicability may vary depending on a department's size, resources, and specific needs.
CLOC/ACC Shortcoming
Just as watching an episode of the lifestyles of the rich and famous - doesn’t really offer us many insights on how we can better use our own limited resources - it just makes us feel envious.
So too with the CLOC and ACC models - they have very limited Day 1 application for most legal teams as a blue print or call to action standing up a legal operations capability.
Firstly and to be clear - the competencies described in each model are all legitimate and desirable. However, they are models of the “rich and famous” legal teams with substantial resources.
If you are in any doubt - take a look at CLOC’s founders and its membership- and consider their access to resources to that of your own legal team.
But the competencies these models describe - who wouldn’t want them. But for the rest of us - small legal teams - here are the shortcomings of these model as it would apply to us:
Utopian State: Describes a Utopian state of a legal operation function but ignores the fact most legal teams will not be able to afford it and if they could - have any chance of implementing it.
Contextual Premise: These models posit an external set of competencies can rescue lawyers from themselves. External forces have mostly proved ineffectual in shaping legal dept. decision making - or within professional service generally.
Us/Them Defect: for most legal teams there will never be a “Day 1” us and them - it will always just be the attorneys. Neither model reflects this reality nor the actual power dynamics within a legal team.
No Starting Point: neither model offers an effective starting point that any team no matter what size can embrace. It just tells you all the things that you don’t have. What do you do on Day 1? How do these models help you?
Design Flaw: whist the competencies highlighted are all correct/desirable - neither model is structured around the reality of a legal team - lawyers, work type, culture, resources, etc. THE core enablers of the model needs to be calibrated to the realities of every legal department and not linked to competencies that done exist or which cannot be afforded.
Organic Evolution: an effective model focuses on improvements to the work the lawyers are doing “today”, that they can contribute to, and that can be validated through data.
Believer Required: no model has much chance of success without a head of legal that is a “believer” in the need for change and the ability to change. Straight away - the attitudes of great swathes of both in-house and private practice leadership many that most organisations are not ready to embrace legal ops.
Small Change Model: all of the above means that the most reliable and realistic model for legal ops can only every be a “small change with proven benefit” model. This excludes setting up new departments, new hires and large IT projects from Day 1.
Educative Cornerstone: neither model places anywhere near enough emphasis of the persistent need for educative progress- the lawyers and the biz all need to be convinced of the benefits. Legal ops is a constant educative exercise as to “how it will benefit us”.
A More Realistic Approach: The GLS Model
GLS believe that the true nature of the operating context of most legal teams means that change must come from within the team - it must be organic.
Any model that relies on external pressure (departmental, decision making, etc) is unlikely to succeed - and our experience shows this to consistently be the case.
Instead of trying to impose external structures, GLS’s model ensures that operational improvements are embedded within the legal team’s existing decision-making structure.
GLS proposes a more practical approach based on slow organically driven change implementing safely, consistently and verifiably over time and calibrated to the unique context (resources, behavioural, cultural, etc) of the legal team.
Our Model is based around four core premises:
1. A model based on what the legal team does: 15 Core Primary Legal Dept. Functions
◼️An effective legal operations model must reflect the world of lawyers rather than trying to introduce entirely new operational structures.
◼️While lawyers will understand the competencies that CLOC and ACC talk about - they are not terms they would use to describe their legal dept. domain.
◼️Accordingly, such models are instantly seen as “external” and “non-core” to the practice of law.
◼️Our Model for legal operations is built around the 15 core workflow and processes that powers the performance of every in-house legal team.
◼️The familiarity of the model to the legal team is a major factor in disarming the attorney natural propensity to reject anything that is new.
◼️Lawyers will recognise and can relate to our model for change as it is built around and designed to impact what they do in a way they recognise.
◼️Making your legal ops model recognisable to he legal team is key - if it has legal team recognition/leadership - it is less likely to be considered administrative initiative - which always has less impact.
2. Mandatory Lawyer Participation
◼️Traditional legal ops models assume the a separately staffed operations function that (e.g. By non attorney staff) - that most teams don’t have budget for this.
◼️GLS’s approach is build a legal ops competency with the attorney as being the Day 1 hire - the lawyers being already paid for assets posing no budgetary implications.
◼️Our model is built with the direct participation of the attorney in mind - indeed 15% of the working week of every attorney should be spent on legal ops.
◼️Now this is only possible if you frame the legal ops contribution so that it is closely aligned to what the lawyers have in their inbox so there is no productivity dilution.
◼️Legal ops improvements should focus on what the lawyers actually do - which makes the initiative relevant, their contribution proximate and the benefits evident.
◼️This is a critical feature of our legal ops model - Change management is - is complex - so the solution must be simple.
◼️Change management hurdles can be largely overcome simply by the choice of initiative you focus on - choose things that your lawyers want to see fixed!
◼️Even better - that the lawyers themselves can play a helpful role in fixing.
3. Zero Cost Basis For Action (RPLV-Based Approach)
◼️The lack of resources is a huge issue that cannot be ignored by any model purporting to be effective at driving legal operations.
◼️Lets just assume that you will not get a greenlight for additional budget, hires, etc. SO what do you do then - does it mean your legal ops agenda is stymied?
◼️You read the CLOC and ACC models and you see a whole lot of items that you do not have and which you cannot afford.
◼️Our Model of RPLV costs nothing to implement and can be implemented in seconds. When it becomes
◼️RPLV is based around …. [ ].
4. Efficient & Safe Action
◼️Neither CLOC nor ACC model support an efficient and effective approach as to “how to get your legal ops” function going.
◼️The GLS model makes it very simple for make a plan for upgrading any aspect of the legal teams performance right through to a whole of function transformation.
◼️Our model represents a picture of what an optimally performing legal department process looks like across 15 vital legal dept. processes.
◼️By breaking down the core “enablers” of an optimally performing legal department process, you can very quickly benchmark how your team is performing.
◼️Whether it be for an entire process, or any part of it, our model allows you to quickly assess how you stack up.
1. Planning becomes - by reference to our Transformation Model - (i) do we have it. Y/N?
2. If yes - how do we stack up (Benchmarking)
3. Identify “wish list improvement” - let a picture of what you could be emerge
4. Prioritise wish list per RPLV principles - superimpose the reality of circumstances into your plan so as to ensure success outcomes.
◼️So, our model allows you to deploy legal ops led improvements on any part of the function - allowing you to engage safe and incremental legal ops implementation.
Note too - our model taps into the inherent desire of most lawyers to be the best/have the best - to overcome a natural proclivity towards not liking change.
Observations and Tips
- Both Frameworks Aim to Structure Legal Operations Improvement: The CLOC Core 12 and ACC Legal Operations Maturity Model are widely used frameworks designed to help legal departments assess and improve operational efficiency through structured competencies and maturity stages.
- CLOC Core 12 Focuses on Core Competency Areas: CLOC defines twelve functional pillars such as financial management, vendor management, technology, knowledge management, and strategic planning to represent essential legal operations capabilities.
- ACC Model Emphasises Maturity Progression: The ACC framework evaluates legal operations across functional areas using staged maturity levels—typically early, intermediate, and advanced—allowing teams to benchmark progress over time.
- CLOC Is More “Functional Architecture” Oriented: It focuses on what functions a legal ops team should have, making it a competency checklist-style model for building structure within legal departments.
- ACC Is More “Development Roadmap” Oriented: It focuses on how mature each function is, helping teams understand current capability levels and what improvements are needed to advance.
- Both Models Assume an Established Legal Operations Function: A key limitation highlighted in practical assessments is that both frameworks are often designed for organisations that already have dedicated legal operations resources.
- Resource Intensity Is a Common Practical Challenge: Full implementation of either model can require significant investment in technology, staffing, and process redesign, which may not be realistic for smaller legal teams.
- Limited Direct Applicability for Lean Legal Teams: In practice, many in-house legal departments find that neither model maps perfectly onto their day-to-day operational structure, especially where legal ops is not a standalone function.
- Best Use Case Is Diagnostic and Benchmarking: Rather than strict implementation, these models are most useful for identifying gaps, prioritising improvements, and creating structured internal discussions around legal operations maturity.
- Overall Insight: CLOC provides the “what” (functional building blocks), while ACC provides the “how far” (maturity progression). Together, they are complementary but require adaptation to fit real-world legal team constraints and resource limitations.
