Operational Due Diligence
& Integration
We assess whether a business can sustain its performance under new ownership. Then we help make sure it does. We work with private equity firms, family offices, M&A advisors, and search fund operators.

Engagements
Three Lenses. Only One Looks Under the Bonnet.
What does the business earn?
Validates historical earnings, normalises financials, and assesses the quality of reported revenue and profit. Answers what the business is worth today.
What are the contractual risks?
Reviews contracts, litigation exposure, regulatory compliance, and intellectual property. Protects the price you pay and informs the purchase agreement.
Can this business actually deliver on the investment thesis once it changes hands?
ODD goes to the engine of the business. It tests whether the operation is genuinely robust or held together by the knowledge, relationships, and workarounds of a few key people. It examines the systems, governance, processes, and dependencies that determine whether a company can function, scale, and transition under new ownership.
People
Where is knowledge concentrated? What happens when key individuals leave?
Systems
Are operations documented and supported by real infrastructure, or patched together?
Governance
Can the business withstand scrutiny from regulators, auditors, and investors?
"Operational due diligence shifts the lens from due diligence to lose, to due diligence to win."
What We Assess
Five operational dimensions that determine whether a business can sustain its performance through a transaction and beyond.
Our methodology is detailed on our Services page
One Firm. Two Phases. Complete Continuity.
From pre-deal assessment to post-deal execution, the same senior team carries the work through. No handover. No lost context.
Operational Due Diligence
A structured, hypothesis-driven assessment of the operational realities beneath the financial performance. Designed to give investors clarity, confidence, and a basis for negotiation.
- ·Deal thesis alignment and scoping
- ·On-site operational deep-dive
- ·Risk, dependency, and key-person mapping
- ·Commercial and strategic analysis
- ·Prioritised findings and action roadmap
Integration and Professionalisation
Hands-on execution of the value creation plan. We implement the governance, systems, and operational improvements identified during assessment.
- ·Governance frameworks and board structures
- ·Systems implementation and process design
- ·Leadership alignment and capability building
- ·Performance management and accountability
- ·Value creation tracking and reporting
The team that identifies the risks is best placed to resolve them. This continuity is what separates assessment from impact.
The ODD Scope Checklist
10 operational questions every investor should answer before closing. A practical framework for scoping what matters.
We'll occasionally share relevant case studies. No spam. No newsletters.
Why Diadem
Three things that define how we work and why clients choose us.
Bespoke to the Deal Thesis
Every assessment is designed around the specific transaction, the specific buyer, and the specific value creation plan. We do not apply a generic checklist. The scope, depth, and focus of our work is shaped by what the investor needs to know.
Continuity from Assessment to Execution
We assess operational risks before the deal closes, then implement the integration roadmap after. The same senior team carries the engagement through. No handover gap. No lost momentum.
Forward-Looking, Not Just Risk-Focused
We identify the operational changes that will accelerate value creation under new ownership. Our findings inform a practical action plan. The question is not just what could go wrong, but what needs to happen next.
Universal Methodology. Sector-Informed Judgement.
Financial Services
Retirement funds, asset management, insurance, and fintech. Governance-intensive environments where regulatory compliance, fiduciary duty, and systems integrity directly determine deal viability.
Food and Agribusiness
Agriprocessing, agricultural inputs, and agtech. Operationally complex sectors with seasonal dynamics, commodity exposure, supply chain fragility, and regulatory requirements that demand practical assessment.
Manufacturing and Distribution
Consumer products, FMCG, and supply chain operations. Capital-intensive businesses where margin sustainability, systems maturity, and operational scalability are central to the investment thesis.
Our assessment methodology also supports transactions in professional services, technology, healthcare, and other sectors where operational complexity is a factor.
