A Greenfield Start-Up Has No Safety Net - Is Your Operation Ready?
When it comes to Operational Readiness (OR), one of the most common misconceptions is that every start-up requires the same level of preparation.
While the principles of Operational Readiness remain consistent – ensuring the organisation has capable people, capable systems and processes, and capable equipment before first production – the execution can look very different depending on whether you’re developing a greenfield facility or expanding an existing brownfield operation.
EnterpriseIS has supported Operational Readiness programmes across mining, manufacturing and utilities projects throughout Australia and internationally. One lesson stands out consistently:
Understanding the differences early helps project teams develop realistic Operational Readiness plans, sufficient budgets, allocate resources effectively and reduce start-up risk.
1. Existing Systems and Processes vs Building Everything from Scratch
The biggest difference between greenfield and brownfield Operational Readiness is the starting point.
In a brownfield project, the organisation already has established business processes, management systems, governance structures, reporting frameworks, maintenance systems and operational procedures. For many of the business functions these can be adopted or modified to suit the new asset.
By contrast, a greenfield project often requires the selection of systems, development of operating philosophies, business processes, maintenance strategies, reporting systems, organisational governance, procedures, work instructions, training materials, technical systems and data structures from the ground up.
The practical result is that greenfield projects typically require a broader and more intensive Operational Readiness effort across all readiness elements. Brownfield projects can often focus resources on the areas that are genuinely new or changed.
There can also be a blended greenfield/brownfield Operational Readiness which applies when a project involves both the creation of new assets, systems, facilities or processes, while also integrating with, modifying, expanding, or operating alongside an existing operation. This will be the subject of an additional blog.
2. Existing Capability and Organisational Knowledge
One of the greatest advantages brownfield projects have is the depth of organisational knowledge that already exists within the business.
A brownfield operation typically has experienced leaders, operators, maintainers, planners, reliability engineers and technical specialists who have successfully operated similar assets, managed production challenges and resolved equipment issues before. These individuals already understand the company’s standards, systems, culture and performance expectations.
When a new asset or expansion is introduced, these subject matter experts can actively participate in:
- Design reviews
- Vendor selection and factory acceptance testing
- Procedure development
- Maintenance strategy reviews
- Commissioning planning
- Training development and delivery
- Start-up and ramp-up support
They also bring something even more valuable: lessons learned.
The organisation already understands what has worked well in the past, where previous start-ups have struggled, and how to avoid repeating mistakes. This institutional knowledge significantly reduces risk during commissioning and the early months of operation.
Greenfield projects face a very different challenge.
There is often no existing operational team to draw upon. The business must recruit key leaders, establish organisational structures, hire operators and maintainers, develop competencies and build a culture, all whilst preparing for first production. Many of these employees may have never worked together before and are learning a new facility, new processes and new organisational expectations simultaneously.
The result is that much more effort is required across Organisational Readiness, Human Resources, Training and Change Management activities simply to create the capability needed to operate safely and effectively.
3. Operating Model Certainty vs Operating Model Discovery
A brownfield expansion often starts with a significant advantage that is frequently overlooked: the organisation already knows how it wants to operate.
The parent operation typically has established:
- Business processes
- Management systems
- Reporting frameworks
- Governance structures
- Maintenance strategies for similar equipment
- Operational philosophies
- Performance metrics
- Continuous improvement processes
These systems have already been tested in a live operating environment. While modifications may be required to accommodate the new asset, the foundations already exist.
As a result, Operational Readiness activities often focus on reviewing, adapting and integrating existing processes rather than developing entirely new ones.
Greenfield projects rarely have this luxury.
Before the operation can safely produce its first tonne, litre or megawatt, the organisation must determine how it intends to operate. Decisions need to be made about:
- Organisational readiness
- Business systems and processes
- Human resources
- HSEC management
- Metrics and reporting
- Procurement, inventory and contracts
- Mining and processing operations
- Asset management etc.
Many organisations underestimate the effort required to establish these systems and often defer decisions until late in the project lifecycle. Unfortunately, this can create confusion during commissioning and ramp-up, as employees are still trying to determine how the business should function while simultaneously attempting to achieve production targets.
In our experience, some of the most successful greenfield start-ups are those that invest early in defining their operating philosophy, management operating system and business processes well before first production. When people understand how the operation is intended to function, they can focus their efforts on achieving a safe and stable ramp-up rather than developing systems on the run.
4. Financial Resilience Is Often Very Different
This is a key difference that can significantly influence project outcomes.
Many brownfield projects are backed by established large operating businesses with significant cashflow. If ramp-up takes longer than expected, the parent organisation usually has the financial capacity to continue supporting operations whilst performance issues are resolved.
Greenfield projects are often more exposed. Many rely on project funding assumptions that require production targets to be achieved within specific timeframes. Delays caused by any equipment reliability or processing issues place significant pressure on cashflow.
In extreme situations, a project that experiences a prolonged or unsuccessful ramp-up may struggle to secure additional funding. Once this occurs, even technically recoverable operational issues can become critical business risks.
This reality reinforces why Operational Readiness should be viewed as an investment rather than a discretionary project cost. EnterpriseIS recommends a structured readiness approach to identify and plan for ramp-up risks because the cost of inadequate preparation can be far greater than the cost of the readiness programme itself.
5. Greenfield Projects Require More OR Deliverables and Budget
The final difference is often the most visible. A greenfield facility is establishing an organisation from scratch, so the volume of readiness deliverables is greater, requiring more funding.
One such example is where a greenfield operation has to develop all of their internal business processes and build these into their newly selected EAP system. A brownfield project is likely to utilise the existing EAP (SAP, Pronto etc.), existing business processes, add the new master data and buy some more licences.
Brownfield projects frequently inherit a significant proportion of these deliverables from existing operations, allowing effort to be concentrated on gap analysis, modification and integration. This often results in lower readiness effort, lower cost and faster implementation.
Quick Comparison
| Readiness area | Greenfield start-up | Brownfield expansion |
| Starting point | Capability is built from the ground up. | Existing systems and processes can often be adopted or modified. |
| People | Roles, workforce plans and capability need to be established. | Existing operational knowledge can support readiness and ramp-up. |
| Systems | Business, technical and maintenance systems often need full configuration. | Established systems may reduce the number of new deliverables. |
| Processes | Processes must match Core business, operating and maintenance processes usually need to be created, defined, documented, approved, embedded into systems and trained before first production. | Existing processes can often be reused or updated, but need gap assessment, impact review, update, communication and integration where the new asset changes how work is planned, executed or controlled. |
| Risk profile | Higher exposure if equipment, systems or funding assumptions are not aligned. | Parent company support can provide funding and support during ramp-up. |
| OR focus | Full OR programme across people, processes, systems, governance, asset data, spares, procedures, training, commissioning support and handover, because most capability must be created before start-up. | Risk-based OR focused on gap analysis, process change impacts, integration with existing operations, workforce transition, system updates, commissioning interfaces and controlled handover. |
The Real Lesson: Tailor Operational Readiness to the Risk
One of the mistakes we occasionally see is applying the same Operational Readiness methodology to every project regardless of context.
The EnterpriseIS Operational Readiness Framework contains 18 integrated elements covering people, processes, systems, governance, infrastructure and assets. However, not every project requires the same depth of effort across every element. The framework is designed to be tailored to the specific operational, commercial and organisational risks of each project.
A brownfield expansion may leverage existing systems, people and expertise, requiring focused effort only where change occurs.
A greenfield development often requires the establishment of nearly every capability required to operate safely, efficiently and sustainably.
Final Thoughts
Whether you’re developing a new mine, expanding a processing facility, building a manufacturing plant or commissioning utility infrastructure, successful start-ups don’t happen by accident.
They are the result of structured planning, disciplined execution and a deliberate focus on developing capable people, capable systems and processes, and capable equipment before first production.
At EnterpriseIS, we’ve helped organisations navigate both greenfield and brownfield start-ups by tailoring Operational Readiness plans to the specific risks, complexity and maturity of each project.
