Board & C-Suite Advisory | Investment Decision Framework
The HAAS Investment Decision Framework
An independent owner-side framework for major infrastructure renewal and Net Zero investment decisions.
Technical planners answer how a solution can be designed and built. System vendors explain which products can be deployed. Project managers control schedule, cost and delivery.
HAAS answers the question that matters to ownership: is this the right investment decision, is it robust under uncertainty, does its logic survive delivery, and does it deliver the expected results in real operation — across all four decision stages of a major capital investment.
Our Approach
Four decision stages. One continuous line of accountability.
We use the term Decision Stage rather than “phase”. A phase describes a period of time. A Decision Stage answers a defined owner question, produces a clear decision basis, ends in a documented owner decision, and releases the next stage — the same discipline used by boards, investment committees and stage-gate governance.
Each stage is delivered through the same independent ownership perspective and Decision Intelligence methodology, from the first pathway screening to long-term performance validation.

Decision Stage 1
Investment Pathway Assessment
Which investment pathways deserve further investigation?
Before capital is committed, HAAS provides an independent, owner-side assessment of the investment pathways available to address a major infrastructure renewal or Net Zero objective.
Rather than validating a preferred technical solution, this stage tests the credible range of pathways against long-term owner value, cost, technical performance and Net Zero ambition.
The outcome is a shortlist of investment pathways worth carrying into detailed evaluation — with a clear, board-ready rationale for what has been excluded and why.
Typical Focus Areas
— Problem framing and investment triggers
— Market and technology scanning
— High-level cost and performance screening
— Net Zero alignment check
— Risk and feasibility screening
— Pathway shortlisting
Executive Deliverables
— Investment Pathway Screening Report
— Shortlist Rationale
— Stage Gate 1 Decision Brief
Stage Gate 1
The owner decides which pathways proceed to detailed evaluation, which are set aside, and whether Decision Stage 2 is released.
Decision Stage 2
Investment Pathway Evaluation
Which investment pathway offers the greatest long-term owner benefit?
Stage 2 subjects the shortlisted pathways to detailed, independent evaluation. Technical, financial and Net Zero performance are tested against the owner’s actual objectives — not vendor assumptions.
HAAS compares pathways on CAPEX, OPEX, total cost of ownership, technical performance, emissions trajectory and risk, and stress-tests the business case behind the preferred option.
The result is the evidence base the Board needs to commit capital with confidence — and the baseline that Stage 3 will subsequently protect.
Typical Focus Areas
— Comparative pathway evaluation
— Business case stress-testing
— CAPEX, OPEX, NPV and TCO analysis
— Net Zero trajectory assessment
— Risk-adjusted comparison
— Board investment case preparation
Executive Deliverables
— Investment Pathway Evaluation Report
— Business Case Validation
— Board Investment Recommendation
— Stage Gate 2 Decision Brief
Stage Gate 2
The owner approves the preferred investment pathway and business case, and decides whether Decision Stage 3 is released.
Decision Stage 3
Investment Delivery Assurance
Protecting the approved investment decision through delivery.
Board approval is only the beginning. Stage 3 safeguards the approved investment pathway through planning, procurement, contract award, implementation and commissioning.
The focus is not day-to-day project control, but protecting the approved investment logic, technical and economic targets, performance requirements, Net Zero goals, accepted risks and the owner’s long-term interests — while design, procurement documentation, construction supervision, formal contract administration and project management remain with the parties the owner has appointed.
HAAS reviews procurement and bid documents, assesses the technical and economic impact of contract terms and change requests, and participates in commissioning of the systems that matter most to performance.
Typical Focus Areas
— Investment decision baseline
— Procurement alignment review
— Technical and commercial bid evaluation
— Contract performance alignment
— Change and value-engineering impact review
— Commissioning and handover validation
Executive Deliverables
— Approved Investment Decision Baseline
— Procurement and Bid Evaluation Reviews
— Contract Performance Advisory Notes
— Change Impact Assessments
— Commissioning and Handover Validation
— Stage Gate 3 Acceptance Brief
Stage Gate 3
The owner decides whether the delivered investment pathway meets approved requirements, which deviations are accepted, and whether Decision Stage 4 is released.
Decision Stage 4
Investment Performance Validation
Does the investment deliver the expected results — and keep delivering them?
Once assets are in operation, Stage 4 independently validates whether the investment pathway is achieving — and sustaining — the technical, economic and emissions outcomes it was approved to deliver.
HAAS reviews operating data supplied by the owner’s monitoring, building management, energy management and MRV systems, reconciles actual conditions against original assumptions, and distinguishes genuine performance shortfalls from changed operating conditions.
Where results fall short, HAAS identifies root causes and recommends corrective or optimisation measures, translating findings into board- and investment-committee-ready reporting.
Typical Focus Areas
— Performance data review
— Baseline and assumption reconciliation
— Target achievement validation
— Variance and root cause analysis
— Operational optimisation support
— Executive performance reporting
Executive Deliverables
— Investment Performance Review
— Baseline and Assumption Reconciliation
— Target Achievement Assessment
— Variance and Root Cause Analysis
— Executive Performance Dashboard
— Stage Gate 4 Performance Brief
Stage Gate 4
The owner decides whether the investment is achieving expected results, which corrective actions to pursue, and at what interval performance will be re-validated.
Executive Capability
Every Decision Stage Includes Executive Investment Translation
Independent evaluation creates insight. Executive Investment Translation turns that insight into confident executive decision-making.
Whatever the stage, every engagement combines three core capabilities.
Independent Evaluation
Technical reality, business case assumptions and alternative investment pathways are independently evaluated from the perspective of long-term ownership.
Executive Investment Translation
Complex technical, commercial, financial and sustainability findings are translated into clear executive investment insights that support confident capital allocation decisions.
Board Decision Support
Boards and investment committees receive clear, independent decision intelligence that strengthens governance, reduces uncertainty and helps protect long-term asset value.
Find Your Stage
Which decision stage matches your situation?
Engagements can start at any decision stage — most owners engage HAAS for a single stage first, then extend as the investment progresses.
Your Situation
Recommended Stage

Why HAAS
Independent by design.
Ownership Perspective
Every recommendation is guided exclusively by the long-term interests of the owner.
No technology sales – No commissions – No vendor influence
Clearly Scoped
HAAS evaluates, challenges and integrates the work of the owner’s appointed specialists. Detailed design, formal construction supervision and technical acceptance, certification, legal and tax advice, formal project management and execution of works remain with those specialists — HAAS does not replace them.
Decision Intelligence
Technical reality, business case assumptions and alternative investment pathways are independently evaluated at every decision stage, from first screening to long-term performance validation.
