In PRINCE2 7, the Business Case is the driving force behind a project, serving as the primary documented justification for the investment. It answers the fundamental question, "Why are we doing this?" by validating that the project is—and remains—desirable (the balance of costs/benefits), viable (the solution can be delivered), and achievable (the benefits can be realized).

Practitioners must treat the Business Case not as a static bureaucratic hurdle, but as a dynamic management tool. It is developed incrementally: starting as a rough mandate, evolving into an Outline Business Case during the 'Starting Up a Project' process, and becoming a detailed Business Case in the 'Initiating a Project' process. Crucially, it must be updated at every Management Stage Boundary to reflect actual progress, current risks, and revised forecasts. It serves as the primary basis for the Project Board's 'Go/No-Go' decisions throughout the lifecycle.

The document structure typically analyzes business options (specifically 'do nothing', 'do the minimum', and 'do something') and details the reasons for the project, estimated costs, timescales, and major risks. A critical component is the Investment Appraisal, which compares the total costs against the expected benefits (measurable improvements) and dis-benefits (perceived negative outcomes). PRINCE2 7 specifically enhances this practice by requiring alignment with organizational sustainability goals and ESG (Environmental, Social, and Governance) targets.

While the Project Manager handles the drafting and updating, the Executive is ultimately accountable for the Business Case, ensuring it aligns with corporate strategy and secures necessary funding. By the 'Closing a Project' process, the Business Case is used to assess the project's final success against the original justification, before transitioning ownership to corporate management for post-project benefits realization.

In the context of PRINCE2 7 Practitioner and the Business Case practice, the Benefits Management Approach is a specialized management product that describes how, when, and by whom the project's benefits will be measured and realized. While the Business Case provides the justification for the project by comparing costs against expected value, the Benefits Management Approach acts as the practical execution plan to ensure that this value is actually achieved.

Its primary objective is to move beyond simple estimation to concrete realization. It defines the specific management actions required to ensure that the project's outputs lead to the desired outcomes and subsequent benefits. The document details the 'scope' of the benefits, the 'baseline' measurements (current performance levels), and the specific 'metrics' used to quantify improvement. Crucially, it establishes the timeline for benefit reviews, which often extends beyond the project's closure into the operational phase.

Regarding roles, the Senior User is ultimately accountable for specifying the benefits and ensuring they are realized, while the Project Manager is responsible for ensuring the approach is created and maintained. The document is first created during the 'Initiating a Project' process. It is then reviewed and updated at every stage boundary to reflect any changes in the Business Case. Finally, during the 'Closing a Project' process, it is updated to schedule post-project benefit reviews, ensuring that the organization tracks long-term value even after the project team has disbanded.

In PRINCE2 7, the Sustainability Management Approach is a pivotal management product designed to define the actions, reviews, and controls required to ensure that a project's outputs and outcomes align with the organization's sustainability goals. It represents a significant evolution in the methodology, placing sustainability—encompassing environmental, social, and economic factors—alongside traditional performance targets like time, cost, and quality.

Within the context of the Business Case practice, this approach provides the necessary framework to validate that the project is not only financially viable but also sustainable. It influences the Business Case by mandating that sustainability requirements be treated as project tolerances and constraints. For a Practitioner, this means that when analyzing business options, the costs associated with sustainable practices (e.g., ethical sourcing, carbon offsetting) and the non-financial benefits (e.g., regulatory compliance, brand reputation) must be explicitly quantified and documented.

The document outlines the specific standards to be applied, how sustainability performance will be measured (KPIs), and how it will be reported to stakeholders. It ensures that the project's justification remains valid throughout the lifecycle by preventing the delivery of products that might generate negative externalities, which would ultimately undermine the corporate strategy. Consequently, the Sustainability Management Approach acts as a governance mechanism, ensuring that the 'desirability, viability, and achievability' of the Business Case are assessed through an ESG (Environmental, Social, and Governance) lens, preventing the authorization of projects that offer short-term gain at the expense of long-term sustainability.

In the context of PRINCE2 7, the Project Brief is a vital management product developed during the 'Starting Up a Project' process. Its primary purpose is to provide a firm foundation for the initiation of the project, ensuring that the Project Board has sufficient information to authorize the 'Initiating a Project' stage. It effectively acts as the trigger for the project's detailed planning phase.

Regarding the Business Case practice, the Project Brief is significant because it contains the **Outline Business Case**. At this early stage, detailed costs, risks, and benefits are often not fully known. Therefore, the Outline Business Case provides a high-level justification, focusing on the business reasoning and options sufficient to justify the investment of time and resources required for the initiation stage itself, rather than the entire project lifecycle.

The Project Brief typically includes:
1. **Project Definition:** Explains what the project needs to achieve (background, objectives, scope, and tolerances).
2. **Outline Business Case:** The initial justification for the project.
3. **Project Product Description:** Defines the quality expectations and acceptance criteria for the final output.
4. **Project Approach:** Describes how the work will be approached (e.g., in-house vs. outsourced, sustainable methods, Agile vs. Linear).
5. **Project Management Team Structure:** Identifies who will manage the project.

Once the Project Board approves the Project Brief, its contents are refined and expanded during the 'Initiating a Project' process to create the Project Initiation Documentation (PID), where the Outline Business Case evolves into the detailed Business Case.

In the context of the PRINCE2 7 Business Case practice, understanding the distinction and relationship between Outputs, Outcomes, and Benefits is critical for justifying a project. These three elements form a chain of value creation that validates the return on investment.

Outputs are the tangible or intangible specialist products delivered by the project. They are simply what the project produces. For example, if a company undertakes a project to implement a new customer relationship management (CRM) system, the Output is the installed software itself. However, possessing the software does not inherently create value.

Outcomes are the results of the change derived from using the project's outputs in business-as-usual operations. Outcomes describe a new state, capability, or behavioral change. Using the CRM example, the Outcome is that the sales team can now access customer data in real-time and automate follow-up emails. The project delivers the Output, but the business achieves the Outcome through transition and adoption.

Benefits are the measurable improvements resulting from an outcome that are perceived as an advantage by one or more stakeholders. They answer the question, 'So what?' regarding the outcome. Continuing the example, the Benefits might be a '15% increase in sales revenue' or '10% reduction in administrative costs.' Benefits must be quantifiable to assess whether the project is desirable, viable, and achievable.

The Business Case documents this logic path: the project builds Outputs, which enable Outcomes, which lead to realized Benefits. PRINCE2 emphasizes that while the Project Manager is responsible for delivering Outputs, the Senior User is responsible for specifying the Benefits and ensuring they are realized.

In the context of PRINCE2 7 and the Business Case practice, Business Objectives and Dis-benefits represent the strategic drivers and the accepted negative consequences of a project, respectively.

**Business Objectives** are the strategic goals of the organization. They are the specific targets—such as increasing market share, achieving net-zero emissions, or complying with new regulations—that corporate management aims to reach. The project is the vehicle used to deliver outputs and outcomes that help realize these objectives. In the Business Case, the project must demonstrate a clear 'Golden Thread' connecting the project's outputs to the realization of benefits that directly support these Business Objectives. If a project does not align with these high-level goals, it lacks strategic justification.

**Dis-benefits**, by contrast, are the measurable declines in the value of one or more objectives that are perceived as negative by stakeholders. PRINCE2 explicitly distinguishes dis-benefits from risks. While a risk is an uncertain event that *might* occur, a dis-benefit is an expected, actual consequence of the project. For instance, a project to automate a factory (Objective: Efficiency) might result in the necessary redundancy of staff (Dis-benefit).

When calculating the desirability of a project within the Business Case, Dis-benefits must be quantified and subtracted from the gross benefits. Ignoring them results in an inflated view of the project's value. PRINCE2 7 highlights that dis-benefits are often the price paid to achieve the Business Objectives; the role of the Business Case is to prove that the positive value of the Objectives outweighs the Costs, Risks, and Dis-benefits combined.

In PRINCE2 7, the Business Case is the driving force behind a project, representing the justification for the investment. It is not a static document but a dynamic instrument that evolves through a specific lifecycle to ensure the project remains desirable, viable, and achievable.

1. **Develop (Starting Up):** The lifecycle begins in the 'Starting Up a Project' process. Here, an **Outline Business Case** is created based on the project mandate. Its purpose is to provide just enough information for the Project Board to decide if the project is worth initiating, acting as a gate to prevent poor ideas from proceeding.

2. **Verify and Baseline (Initiating):** During the 'Initiating a Project' process, the outline is refined into the **Detailed Business Case**. This serves as the performance baseline, detailing costs, risks, and expected benefits. Concurrently, the Benefits Management Approach is developed to define how and when benefits will be measured.

3. **Maintain and Confirm (During the Project):** throughout the lifecycle, specifically at each **Stage Boundary**, the Business Case is updated with actual data (costs incurred) and revised forecasts. The Project Board reviews this to ensure the project still offers value for money before authorizing the next stage. If the justification disappears, the project should be stopped.

4. **Assess (Closing):** Finally, in 'Closing a Project', the Business Case is reviewed to compare the final project outcomes against the original baseline. While the project ends, the Business Case lifecycle extends into the post-project period where the **Benefits Management Approach** tracks the realization of long-term benefits.

In PRINCE2 7, establishing business justification is a foundational principle and practice that ensures a project remains desirable, viable, and achievable throughout its lifecycle. It acts as the primary driver for decision-making, preventing projects from continuing when they no longer provide value. This practice is not merely a box-ticking exercise at the start; it is a continuous requirement. If the justification ceases to exist at any point, the project should be stopped to prevent wasted resources.

The central management product for this practice is the Business Case. In the Practitioner context, managing the Business Case involves four specific activities: developing, verifying, maintaining, and confirming. Initially, an Outline Business Case is created during the 'Starting a Project' process to justify the initiation stage. This is expanded into a detailed Business Case during 'Initiating a Project' to provide a baseline for the project.

Crucially, the Business Case must be verified at every Stage Boundary by the Project Board, led by the Executive who holds ultimate accountability. They assess whether the project is still worth the investment based on updated costs, risks, and timescales. The document is also maintained throughout the project; as stages complete, estimates are replaced with actual data, and forecasts are revised. Finally, the practice involves confirming benefits via the Benefits Management Approach, which tracks the realization of value often extending beyond the project's closure. PRINCE2 7 further emphasizes aligning this justification with organizational sustainability goals and strategy, ensuring that the project delivers holistic value rather than just immediate outputs.

In the context of PRINCE2 7, aligning products to business objectives is fundamental to the 'Business Case' practice and the principle of 'Continued Business Justification.' This alignment is achieved by establishing a clear logic trail, often referred to as the 'Chain of Causality' or the benefits dependency network.

The process begins with the project **Output** (the specialist product or deliverable). However, a product alone does not represent value; it is merely an enabler. The alignment process requires mapping how the product will be utilized by the business to create a change, resulting in an **Outcome**. An outcome is the result of the change derived from using the project's outputs (e.g., 'Staff can process orders 50% faster').

These outcomes must then translate into **Benefits**, which are the measurable improvements perceived as positive by stakeholders (e.g., 'Reduced operational costs by $100k'). Crucially, these benefits must map directly to the organization’s **Corporate or Programme Objectives**. If a project delivers a product that yields benefits irrelevant to the organization's strategic goals, the project lacks alignment and validity.

In PRINCE2 7, the Business Case must explicitly demonstrate this linkage. If the chain breaks—where a product does not lead to a desired outcome, or an outcome does not yield a strategic benefit—the project is not viable. Therefore, aligning products to objectives involves rigorous analysis to ensure that every feature of the specialist product contributes to a chain of events that ultimately advances the organization's strategic strategy.
