I help organisations transform differently by putting people at the centre of change and connecting ambition to action. With experience at Accenture, Deloitte, and my own practice, I cut through noise to focus on the drivers of lasting transformation. Known for rapid results in 90–180 days, I simplify complexity, align leadership, and put people at the centre so change sticks.  

As a transformation and change expert, I’ve led complex transformations, integrations, and turnarounds, often stepping in as interim Transformation Director, Change Director, Strategy Director, Programme Director, COO, or CEO. I have worked across various industries, including financial services, fintech, insurance, investment management, legal, utilities, retail, media, and PE-backed businesses. My expertise spans business agility, technology simplification, and customer proposition redesign, creating sustainable impact and leaving organisations stronger than I found them.

I’ve delivered programmes exceeding £100 million, led teams of more than 400 people, and created measurable results, including 30 percent cost reductions, a £265 million uplift in enterprise value, successful regulatory recoveries, and scalable digital platforms.

Alongside my transformation work, I coach leaders and teams to build clarity, accountability, adaptability, resilience, and confidence through change. I help organisations strengthen their leadership capabilities, align teams around a shared purpose, and develop the cultural and behavioural foundations that make transformation sustainable.

How I can help your organisation:
-	Strategy development and programme delivery 
-	Digital, AI, and data-enabled change
-	Enterprise transformation and operating model design
-	Post-acquisition integration
-	Embedding agile and new ways of working at scale
-	Regulatory remediation and governance improvement
-	Culture, leadership, and team performance alignment
-	Executive coaching and leadership team development

Every sector has its quirks, but transformation fundamentals remain the same: clear vision, practical execution, and genuine partnership between leadership and teams.

Four and One Consulting

Four and One Consulting helps business leaders ensure that their people are capacitated to execute against business strategy in an increasingly complex and competitive working landscape.  

Your people are often your highest fixed operational expense - and their productivity levels can make or break your business. Leveraging benchmark research and analytics, together with a unique blend of business management and behavioural psychology principles, Four and One Consulting partners organisations to grow their people by identifying and addressing performance barriers, whilst simultaneously increasing businesses output. 

What we do:

We help organisations get the best out of their people and get the best out of their technologies.

Four and One Consulting specialises in driving business growth in two distinct areas; 

(i)	Driving personal growth and performance

We do this by enabling your people to take greater ownership of their work and by helping them identify a greater sense of ‘self’ within what they do and why they do it. All the while increasing their individual job role output. Through our research we have found that a person can significantly improve their job performance by increasing their level of job related psychological ownership. 

(ii)	Driving digital adoption

We take a bespoke behavioural view in ensuring that people possess the skills and capabilities to effectively engage digital systems. This, together with an enabling environment, we believe, is of utmost importance when we consider that less than 30%1 of professionals admit they are unable to effectively use their digital systems.    

If your business is ready to grow its people whilst increasing the businesses output in an ever changing and competitive world, Four and One Consulting is ready to assist.

Craig McKenzie Personal Bio

If you consider that people and technology are the two most common denominators in almost every business, imagine what would happen you were able to increase their performance output, even nominally. The sum of these nominal increases could have a profound impact on your business. 

I fundamentally believe that through deliberate and concerted effort, we all possess the ability to improve our performance output in our chosen fields. I’m a management consultant with 14 years of industry experience guiding mid-market businesses to source, procure and implement SaaS technologies. 

Having worked within the management consulting, HR, digital, EdTech, behavioural, and people performance landscape for more than a decade, I founded Four and One Consulting with the vision and aim of guiding businesses to source, procure and implement SaaS technologies. As such, we take a client-centered approach to understanding and addressing your technology needs. 

We work on behalf of our clients, NOT the vendor. 

I have a passion for people performance, enabling technology and behavioural psychology, and I am motivated by combining these passions in deriving ways for people and businesses to understand more about themselves in order to perform and grow.
