Episode 46: Discovery Phase: Business Case and ROI Analysis
The discovery phase is the critical starting point of any project because it determines whether the effort should move forward at all. This stage involves gathering early information, consulting stakeholders, and evaluating whether the potential benefits justify the required investment. Strong discovery work helps reduce future rework, prevents misaligned initiatives, and ensures that proposed projects are in line with strategic goals. Key deliverables from this phase often include the business case, return on investment (ROI) projections, and a high-level feasibility assessment.
A business case is the central document in the discovery phase. It explains why the project is needed, what benefits it will deliver, and how it addresses a specific problem or opportunity. It presents the proposed solution, details alternatives considered, and outlines the expected results. A well-prepared business case serves as the formal justification for funding and resource allocation, often reviewed by sponsors or decision-makers before the project is formally approved.
The components of a strong business case include background information that explains the context, the objectives the project will achieve, and how the effort aligns with organizational strategy. It must also provide cost estimates, projected benefits, and a discussion of risks that might affect outcomes. Timelines, resource needs, and defined success criteria may also be included. The document should be concise and tailored to its audience—executives want clarity, not excessive technical detail.
A clear problem statement within the business case defines the gap or opportunity driving the initiative. This statement must be specific and unambiguous so that stakeholders have a shared understanding of the challenge. Business objectives should describe, in measurable terms, what the project aims to achieve. Objectives linked directly to strategic organizational goals strengthen the justification for moving forward and later serve as benchmarks for performance tracking.
Calculating ROI is a central part of the discovery phase. ROI compares the net benefits of a project to its total costs, expressed as a percentage. The formula is straightforward: ROI = (Net Benefit ÷ Total Cost) × 100%. A positive ROI indicates that the expected gains outweigh the investment. These benefits can include revenue growth, efficiency improvements, or cost savings, and should be quantified whenever possible. In some cases, ROI can also reflect non-financial benefits such as improved customer satisfaction or reduced risk exposure.
Estimating ROI, however, comes with challenges. Intangible benefits like improved employee morale or brand reputation are difficult to assign a numeric value to. Early cost projections may lack detail because requirements are not fully defined. There is also a risk of presenting overly optimistic figures to gain approval, which can damage credibility later. Using conservative, well-supported estimates increases stakeholder confidence and reduces the likelihood of overpromising.
Considering alternative solutions is a vital part of the business case. This comparison process evaluates multiple approaches to solving the identified problem, weighing each against cost, feasibility, and alignment with strategic goals. Documenting the alternatives considered—along with the rationale for selecting the preferred option—demonstrates transparency and helps build trust among decision-makers.
Stakeholder identification is another essential discovery activity. Engaging the right stakeholders early ensures that the project accounts for all perspectives, requirements, and constraints. Stakeholders may be internal teams, external vendors, customers, or regulatory bodies. Their feedback can help refine assumptions, identify priorities, and improve feasibility assessments. Documenting stakeholder involvement strengthens the credibility of the business case.
Assumptions and constraints should be clearly stated so expectations are realistic. Assumptions are conditions believed to be true for planning purposes, while constraints are limits such as budget ceilings, fixed deadlines, or compliance requirements. Capturing these early ensures they are considered during scope, schedule, and risk planning in later phases.

A feasibility assessment is often the final checkpoint in the discovery phase before a project moves forward. This evaluation determines whether the proposed solution is practical and achievable given the organization’s current capabilities, resources, and constraints. It examines technical requirements, financial viability, and operational readiness, sometimes assigning a feasibility score to help prioritize projects. A positive feasibility outcome gives decision-makers confidence to proceed, while a negative or low score may lead to modification or rejection of the proposal.
Strategic alignment is one of the strongest factors influencing approval in the discovery phase. Projects that directly support organizational objectives are far more likely to receive funding and executive sponsorship. Referencing strategic plans, KPIs, or mission statements in the business case reinforces how the proposed project delivers measurable value. When stakeholders see a clear connection between the project’s objectives and the organization’s priorities, commitment to its success increases.
Another discovery deliverable is the preliminary scope outline. This is not a detailed scope statement but rather a high-level boundary of what the project will and will not address. It frames the estimated size, complexity, and capabilities needed for execution. Early clarity in scope helps prevent misalignment later in planning and sets more realistic expectations for budget, schedule, and resource needs.
High-level cost and benefit estimates also emerge during discovery. These early estimates often draw from historical project data, expert judgment, or parametric models. Because details are limited, cost ranges are acceptable at this stage, but they must be transparent about their level of uncertainty. Benefits should be quantified wherever possible to strengthen the ROI calculation, and the total cost of ownership (TCO) may be included to account for ongoing maintenance and support costs after implementation.
Risk identification during discovery is a sign of thorough preparation. At this stage, risks are usually flagged at a category level rather than fully analyzed. Examples might include technical feasibility challenges, potential stakeholder resistance, or market volatility. By identifying these early, the project team can carry them forward into the risk management plan for deeper analysis during planning.
Justifying the recommended solution is the culmination of the business case. The preferred option should be defended with a balanced argument that includes ROI data, strategic alignment, and an understanding of associated risks. Referencing lessons learned from similar past projects can strengthen the case. Recommendations should be realistic, evidence-based, and supported by key stakeholders to improve the likelihood of approval.
When presenting the business case to decision-makers, an executive summary is essential. This concise section highlights the problem, the proposed solution, and the expected return. Decision-makers often rely on this summary for their first impression, so it must be clear and persuasive. Presenters should be ready to answer questions about scope, cost, benefits, and risks. Visual aids—such as charts, timelines, and ROI comparisons—can make the proposal more engaging and easier to understand.
Documenting outputs from the discovery phase ensures that all supporting evidence and decisions are preserved. Core deliverables include the business case, ROI analysis, stakeholder summary, and any feasibility findings. Supporting materials such as meeting notes, estimates, and stakeholder feedback should be version-controlled and stored in a central repository for easy reference. These documents become the foundation for the initiation and planning phases, guiding more detailed project work.
In summary, the discovery phase defines the “why” behind a project. It uses business cases, ROI calculations, and feasibility assessments to determine whether an idea should move forward. When done thoroughly, discovery work aligns the project with organizational value, strategy, and stakeholder priorities. It sets the tone for all that follows, reducing risk, increasing stakeholder confidence, and improving the odds of delivering a successful outcome.
