## Purpose of the Business Case Theme
The Business Case Theme in PRINCE2 establishes mechanisms to judge whether the project is (and remains) desirable, viable, and achievable. Its primary goal is to support decision-making for the project's continued investment. This theme directly underpins the PRINCE2 principle of Continued Business Justification, ensuring that the project always has a valid reason to proceed and that its benefits outweigh its costs and risks.
## The Business Case Document
The Business Case is the key management product for this theme. It provides the justification for the project and is owned by the Executive. It evolves throughout the project lifecycle:
Key components of the Business Case include:
## Benefits Management Approach (BMA)
The Benefits Management Approach is a plan that defines how and when the project’s benefits will be identified, measured, monitored, and reviewed. It also assigns responsibilities for benefit realization. This approach is created in the Initiating a Project process and refined as needed.
## Roles and Responsibilities
## Integration with Processes
## Organization Theme: Defining Roles and Responsibilities
The Organization theme establishes and defines the project's structure of accountability and responsibilities. It ensures that the project management team has a clear and effective structure, with defined roles and responsibilities, enabling effective decision-making and communication. This theme addresses the PRINCE2 principle of "Defined roles and responsibilities," ensuring everyone knows their role and what is expected of them.
## Project Management Team Structure
PRINCE2 defines a scalable project management team with four levels of management:
## Key Roles and Responsibilities
Beyond the core Project Board and Project Manager, other crucial roles support the project:
## Tailoring the Organization Theme
PRINCE2 roles are descriptions of responsibilities, not job titles. They can be combined or split depending on the project's size, complexity, and context. For instance, in a small project, the Project Manager might also perform Project Support duties, or a single person might cover both Senior User and Senior Supplier roles if appropriate skills exist and no conflict of interest arises. The key is to ensure all responsibilities are clearly allocated and understood. The Communication Management Strategy is a key management product that defines how and when communication will occur between these roles and external stakeholders.
## Quality Theme in PRINCE2
The Quality theme addresses how the project will ensure that its products are fit for purpose. It focuses on defining and implementing the means by which the project will create products that meet the agreed requirements. The aim is to deliver products that meet both the customer's expectations and the specified quality criteria.
## Key Concepts
## Responsibilities
By effectively applying the Quality theme, PRINCE2 ensures that the project delivers products that are fit for purpose, meeting both the customer's expectations and the specified quality criteria throughout the project lifecycle.
## The Plans Theme in PRINCE2
The Plans theme in PRINCE2 provides a framework for designing, developing, and maintaining plans. Its primary purpose is to facilitate communication and control by defining *how*, *when*, and *by whom* specific products are to be created. Plans are central to how the Project Board and Project Manager exercise control and measure progress, providing a baseline for monitoring.
PRINCE2 mandates a minimum of two levels of plans and introduces an optional third:
PRINCE2 emphasizes product-based planning, a technique that focuses on identifying and defining the products required *before* considering the activities needed to create them. The steps are:
1. Design the Plan: Define the planning approach.
2. Define and Analyze Products: This key step involves creating a Product Breakdown Structure (PBS), writing Product Descriptions (PDs) for each major product, and developing a Product Flow Diagram (PFD) to show dependencies.
3. Identify Activities and Dependencies: Determine the tasks required to produce each product and their sequence.
4. Prepare Estimates: Estimate effort, duration, and cost for activities.
5. Prepare the Schedule: Allocate resources and define timescales.
6. Analyze Risks: Identify and assess risks related to the plan.
7. Document the Plan: Compile the plan into a formal document.
The Plans theme is closely associated with several key management products:
Plans provide the baseline against which progress is monitored and controlled, ensuring the project remains viable and aligned with objectives.
## The Risk Theme: Managing Uncertainty
The Risk Theme in PRINCE2 provides a structured approach to identifying, assessing, and controlling uncertainty throughout the project lifecycle. Its purpose is to ensure that the project team and stakeholders understand the project's risks, and that appropriate actions are taken to manage them, thereby improving the chances of project success.
A risk is an uncertain event or set of events that, should it occur, will have an effect on the achievement of objectives. Risks can be categorized as threats (negative impacts) or opportunities (positive impacts). Risk appetite defines the amount of risk an organization or project is willing to take, typically expressed as tolerance levels.
PRINCE2 outlines a five-step procedure for managing risks:
Responses are tailored based on whether the risk is a threat or an opportunity:
Effective risk management ensures that project decisions are made with a clear understanding of potential future events.
## The Purpose of the Change Theme
The Change theme in PRINCE2 provides a framework for identifying, assessing, and controlling any potential changes to the project's baselines (products, plans, and requirements). Its primary purpose is to ensure that only worthwhile changes are approved and implemented, preventing uncontrolled scope creep and maintaining the project's viability. It ensures that all project products are correctly identified, managed, and protected throughout their lifecycle.
## Key Concepts and Definitions
## Managing Issues and Changes
The approach to managing issues and changes is defined in the Configuration Management Strategy. This strategy outlines how the project's products will be controlled, including planning, identification, control, status accounting, and verification. It also details the Change Control Approach, which describes the procedure for managing issues.
When an issue arises, it is captured in the Issue Register and detailed in an Issue Report. The Project Manager will analyze the issue, assess its impact on objectives, and recommend actions. For significant issues, particularly Requests for Change and Off-Specifications, they are referred to the Change Authority for a decision. The Change Authority will decide whether to approve, reject, defer, or seek more information. Approved changes are then implemented and tracked.
## Management Products and Responsibilities
Key management products for the Change theme include:
Responsibilities: The Project Board appoints the Change Authority and approves the Configuration Management Strategy. The Project Manager prepares the strategy, manages the Issue Register, and prepares Issue Reports. The Change Authority makes decisions on significant changes.
## Progress Theme Overview
The Progress Theme in PRINCE2 establishes mechanisms to monitor and compare actual achievements against planned objectives, forecast future performance, and control deviations. Its primary purpose is to ensure the project remains viable against its Business Case and to provide transparency to stakeholders regarding performance.
## Management by Exception and Tolerances
A core principle of PRINCE2, Management by Exception, is fundamental to progress control. This involves setting specific tolerances for each management level (project, stage, work package) across six performance targets: time, cost, quality, scope, benefits, and risk. Management by Exception means that the next level of management is only involved if these agreed tolerances are forecast to be exceeded, or have already been exceeded. This allows for efficient decision-making and saves management time.
## Reporting and Review Mechanisms
Effective progress control relies on regular reporting and reviews. Key reports include:
## Baselines and Control
All plans (Project Plan, Stage Plan, Team Plan) are baselined once approved. These baselines serve as the fixed reference points against which actual progress is measured. By monitoring progress against these baselines and reporting deviations, the Project Manager can maintain control, escalate issues when necessary, and ensure the project stays aligned with its objectives and the Business Case.
## Tailoring PRINCE2 to the Project Environment
Tailoring is the act of adapting PRINCE2 to suit the specific context of a project. It ensures that PRINCE2 is applied effectively and efficiently, avoiding unnecessary overhead while maintaining control. PRINCE2 is not a one-size-fits-all solution; it must be adjusted to fit the project's unique characteristics.
## Why Tailor?
The primary goal of tailoring is to ensure the project management method is appropriate for the project's scale, complexity, risk, and environment. This maximizes the benefits of using PRINCE2 by making it practical and effective, rather than a bureaucratic burden. Tailoring helps integrate PRINCE2 with the organization's existing management systems and culture.
## What to Tailor?
Tailoring involves adapting various elements of PRINCE2:
## Factors Influencing Tailoring
Several factors dictate how PRINCE2 should be tailored:
## Who is Responsible and When?
The Project Manager is typically responsible for proposing the tailored approach. This proposal is then reviewed and approved by the Project Board, often as part of the Project Initiation Documentation (PID). Tailoring decisions are primarily made during the Starting Up a Project and Initiating a Project processes, and documented in the Project Approach section of the PID. Tailoring should be periodically reviewed and adjusted if the project context changes.
## Key Principles of Tailoring
Crucially, the seven PRINCE2 Principles are non-negotiable and must always be applied. Tailoring is about *how* these principles are applied, not *whether* they are applied. The aim is to achieve effective project governance and control without adding unnecessary bureaucracy.
