    Study Notes

    Project Quality Management

    • Project quality management is the process of frequently measuring the quality of all project activities and taking corrective action until the desired quality is achieved.
    • It includes processes for incorporating the organization's quality policy regarding planning, managing, and controlling project/product quality requirements to meet stakeholder objectives.
    • The purpose of project quality management is to ensure the project satisfies the needs for which it was undertaken.
    • Project management fundamentally involves meeting or exceeding stakeholder needs and expectations.
    • If stakeholders are dissatisfied with the quality of project management or project deliverables, the project team needs to adjust scope, time, and cost to achieve satisfaction. Meeting only written requirements is insufficient.

    What is Quality?

    • ISO defines quality as the totality of characteristics of an entity that bear on its ability to satisfy stated or implied needs.
    • Alternatively, quality is what the customer or stakeholder needs from project deliverables/outputs.
    • Other experts also define quality based on conformance to requirements (meeting written specifications/task completeness) and fitness for use (ensuring the product can be used as intended).

    Modern Quality Management

    • Modern quality management emphasizes customer satisfaction (tackling problems in real-time).
    • Prevention is prioritized over inspection for quality improvement.
    • Management is responsible for quality.
    • Steps are established and determined to achieve quality standards.
    • Project costs are controlled by tackling issues before affecting the budget.

    Project Quality Management Processes

    • Quality planning involves identifying relevant quality standards for the project and how to satisfy them.
    • Quality assurance evaluates the overall project performance to ensure meeting relevant quality standards.
    • Quality control involves monitoring and checking specific project results to ensure compliance with quality standards and identify ways to improve overall quality.

    Quality Planning

    • Identifying relevant quality standards and how to meet them for the project.
    • Documenting the project's quality requirements, management methods, and delivery methods (e.g., meetings, emails, etc.).
    • Including quality metrics for measuring quality (e.g., a quality checklist).
    • A quality management plan is a document that maintains quality standards throughout the project's execution and completion.

    Quality Assurance (QA)

    • QA is the process encompassing all activities related to satisfying the relevant quality standards for a project.
    • Quality assurance involves translating a quality management plan into executable quality activities that incorporate the organization's quality policies into the project.
    • An important tool for managing quality is a quality audit.
    • Important inputs for performing quality assurance include the quality management plan, process improvement plan, quality metrics, quality control measurements, and project documents.
    • Key activities include process audits, process improvement, and training.

    Quality Control (QC)

    • QC involves monitoring and recording specific project results to ensure compliance with relevant quality standards.
    • Project outputs must be complete, correct, and meet customer expectations.
    • QA focuses on improving processes to prevent quality issues, while QC focuses on inspecting and identifying quality issues.
    • QC's main outputs are acceptance decisions, rework, and process adjustments.
    • Key activities include inspection, testing, and defect identification/correction.

    Key Differences: QA and QC

    • QA focuses on process improvement to prevent defects, while QC focuses on identifying and fixing defects at the end of project phases.
    • QA occurs throughout the project lifecycle, while QC occurs at the end of phases/deliverables.
    • QA ensures proper processes, while QC ensures defect-free outputs.

    Tools and Techniques for Quality Control

    • Some tools and techniques for quality control include Pareto analysis, testing (functional, performance, stress, and user acceptance), statistical sampling, and quality control charts.
    • Project managers effectively maintain and improve quality deliverables by using these methods.

    Pareto Analysis

    • Identifying the vital few contributors responsible for the most quality problems in a system (the 80/20 rule).
    • Pareto diagrams—histograms—are used to identify and prioritize problem areas.

    Testing

    • Evaluating a product, service, or process to ensure it meets predefined quality standards.
    • Various testing types include functional, performance, stress, and user acceptance testing.
    • Testing verifies product functionality and meets customer expectations.
    • Testing benefits include reduced defect likelihood reaching the customer and enhanced customer satisfaction and confidence.
    • Testing occurs throughout the software development life cycle, not just at the very end. Testing can be manual or automated.

    Types of Tests

    • Unit tests assess individual components, ensuring they are defect-free.
    • Integration tests evaluate functionalities of grouped components.
    • System tests examine the entire system as one entity.
    • User acceptance tests involve end-users verifying system functionality before final acceptance.

    Cost of Quality (COQ)

    • COQ encompasses all costs associated with product quality, categorized as prevention, appraisal, internal failure, and external failure.
    • Costs related to quality can be classified as prevention, appraisal, internal error, and external error.
    • Prevention costs include investments focused on avoiding defects or errors.
    • Appraisal costs are related to the assessment of products or services to ensure conformance to quality standards.
    • Internal error costs are associated with reworking or fixing defects before customer delivery.
    • External error costs are related to issues arising after customer delivery, like rework or warranty repairs.

    ISO 9000

    • International set of quality standards applicable to various industries.
    • ISO 9001 is a generic quality model tailored for organizations that design, develop, and maintain products.

    Software Quality Attributes

    • A list of software quality attributes such as Safety, Security, Understandability, Portability, Testability, Usability, Reliability, Adaptability, Reusability, Resilience, Modularity, Efficiency, Robustness, Complexity, and Learnability.
