Why Capital Investment System (CIS) Exists

Most organisations involved in capital projects have highly experienced engineers, geologists and project professionals.

More often, the issue lies in how projects are developed and governed. It comes down to how decisions are made, how risk is understood, and how readiness is assessed before capital is committed.

The Real Risk Lies in Early Decisions

The most critical decisions in a project are not made during execution. They are made during the study phases.

By the time a project is approved, the key assumptions, risks and constraints are already embedded in the concept.

If these are not properly tested and understood, strong execution cannot recover the outcome.

Projects do not typically fail because they are poorly executed.

They fail because they are approved with unresolved uncertainty.

The Challenge of False Confidence

As projects progress through study phases, more detail is added.

However, more detail does not necessarily reduce uncertainty.

In many cases, a preferred option continues to be refined without sufficient challenge to the underlying assumptions or adequate evaluation of alternatives.

This can create a level of confidence that is not supported by the true level of risk.

This is where many investment decisions quietly go wrong.

Where the CIS Came From

The principles behind the Capital Investment System (CIS) have been established over decades.

Many of the foundational practices were developed in the oil and gas sector and adopted by large EPCM organisations such as Bechtel and Fluor.

Mining companies later adapted these approaches as projects increased in scale and complexity.

Historically, much of this knowledge was not formally documented. It was transferred through experience rather than structured systems.

The Origin of the Enthalpy CIS

In the early 1990s, Enthalpy began capturing these principles into a structured framework.

What began as an internal approach has since evolved into Enthalpy’s Capital Investment System.

Over time, it has been applied, refined and improved through real project work across major owners and projects in the resources and infrastructure sectors globally.

Today, it reflects decades of practical experience in:

• project studies
• capital investment decision making
• project governance
• execution planning

What the CIS Actually Is

The CIS is a structured approach to developing, evaluating and executing capital investments.

It brings consistency to how projects are assessed, not just how they are delivered.

At a high level, it includes:

• structured study phases (Scoping → Prefeasibility → Feasibility)
• clearly defined minimum standards
• stage-gate investment decisions
• independent peer reviews before capital commitment
• governance frameworks for project delivery

What differentiates the CIS is not the existence of these elements, but the discipline in how they are consistently applied across projects and decision gates.

Together, they provide a clear and consistent framework for assessing project maturity and readiness.

Why This Matters for Project Owners

Capital projects involve significant investment and long term commitments.

Boards, investors and lenders need confidence that:

• risks are understood
• options have been properly evaluated
• projects are ready before funds are committed

Well-developed projects typically demonstrate:

• comparison of multiple development options
• clear levels of study maturity
• transparent articulation of risk and uncertainty
• realistic cost and schedule ranges
• independent challenge before key decisions

These are the characteristics that lead to better outcomes.

The Cost of Getting It Wrong

Once a project moves into execution, the ability to influence outcomes reduces rapidly.

Changes become more expensive. Risks become harder to manage. Options become limited.

In many cases, projects do not fail during execution. They fail because they were approved before they were ready.

Why the CIS Still Matters Today

Projects are becoming larger, more complex and subject to greater scrutiny.

In this environment, structured governance and disciplined project development are essential.

The Capital Investment System provides a practical framework, built on decades of experience, to improve the quality of investment decisions.

At its core, it helps answer a simple but critical question:

Is this project truly ready for the next investment decision?
