Quality Checking Methods
Quality Checking Methods are the specific techniques and approaches used to verify whether a product meets its defined Quality Criteria. In PRINCE2, these methods are documented in Product Descriptions and outline exactly how quality will be measured, tested, or inspected. Quality Checking Methods transform abstract quality requirements into concrete verification activities, ensuring consistent assessment across the project. They can range from simple visual inspections to complex automated testing protocols, depending on the nature of the product. Common examples include user acceptance testing, peer reviews, prototype demonstrations, performance testing, compliance audits, and statistical sampling. The selection of appropriate Quality Checking Methods depends on factors such as the product's complexity, criticality, available resources, and organizational context. Each method should be aligned with specific Quality Criteria and must be practical to implement within project constraints. Quality Checking Methods should specify who will perform the checks, when they will occur, what tools or resources are needed, and how results will be documented. They form the bridge between theoretical quality standards and practical quality verification activities. When properly implemented, these methods provide objective evidence of product quality, reduce subjective judgments about acceptance, and create audit trails for quality verification. Project managers should ensure that Quality Checking Methods are proportionate to the risks associated with product quality failures and are agreed upon by those responsible for both producing and accepting the products.

Quality Checking Methods in PRINCE2: A Comprehensive Guide
Quality checking methods are essential components of the Quality Theme in PRINCE2 methodology. This guide will explore what these methods are, why they're crucial, how they work, and how to approach exam questions on this topic.
Why Quality Checking Methods Are Important
Quality checking methods ensure that products meet defined standards and fitness criteria. They are important because:
• They help identify defects early in the project lifecycle
• They reduce costly rework and delays
• They ensure customer requirements are met
• They maintain stakeholder confidence
• They support consistent delivery of quality products
In PRINCE2, quality is planned rather than inspected. Quality checking methods are the practical mechanisms that enable this proactive approach.
What Are Quality Checking Methods?
Quality checking methods are the techniques used to verify that products meet their quality criteria. PRINCE2 recognizes three primary types:
1. Quality Inspection - A formal, systematic evaluation against predefined standards
2. Quality Testing - The process of examining a product to find differences between what exists and what is required
3. Quality Review - A structured approach to assess a product involving multiple reviewers
Quality reviews can be further categorized into:
• Peer Review: Examination by colleagues with similar expertise
• Technical Review: Formal review focused on technical aspects
• Quality Gate: Review at key transition points in development
• Walkthrough: Guided review by the producer of the product
• Inspection: Rigorous review conducted by a trained moderator
How Quality Checking Methods Work
The implementation of quality checking methods follows a structured process:
1. Planning: Determine which quality check method is appropriate based on product type and project context
2. Defining Quality Criteria: Establish measurable standards the product must meet
3. Developing Quality Checking Procedures: Document how checks will be performed
4. Allocating Responsibilities: Assign roles for quality checking (e.g., who will review)
5. Scheduling Quality Activities: Include quality checks in the project schedule
6. Executing Quality Checks: Perform the selected method
7. Recording Results: Document findings, defects, and improvement suggestions
8. Follow-up Actions: Address identified issues and verify corrections
Quality checking methods are documented in the Quality Management Strategy and Product Descriptions, with specific quality activities detailed in Work Packages.
Exam Tips: Answering Questions on Quality Checking Methods
• Know the terminology: Understand the differences between inspection, testing, and various types of reviews
• Focus on roles: Remember that the Project Manager ensures quality checks are planned and executed, while Team Managers implement them
• Connect to other themes: Recognize how quality checking relates to risk management and configuration management
• Understand the sequence: Quality criteria are defined first, then appropriate checking methods are selected
• Remember documentation: Know where quality checking methods are documented (Quality Management Strategy, Product Descriptions, Work Packages)
• Identify responsibilities: Be clear on who is responsible for quality at each level (corporate/programme, project, delivery)
• Apply context: Consider the scenario given and tailor your answer to the appropriate checking method for that situation
• Look for keywords: Terms like "review," "inspection," or "testing" in questions often point to quality checking methods
When facing multiple-choice questions, eliminate options that contradict PRINCE2 principles. Quality is planned from the start, not just checked at the end - this fundamental concept often separates correct answers from incorrect ones.
