Definition: Quality refers to the minimum requirements set by the client or the degree of excellence that a product, system, or service must meet.
Purpose: Ensures that the outcome fulfills its intended function effectively and meets customer satisfaction.
🛠️ Quality Assurance (QA)
Definition: QA is the systematic process of setting standards, procedures, and parameters to ensure the quality of a project from the start.
Focus: It is process-based, emphasizing prevention of defects rather than correction.
Timing: Done before Quality Control (QC).
Approach: It is a proactive tool aimed at improving work processes.
Involvement: Requires teamwork and planning.
🔍 Key QA Activities:
Defining project standards and specifications.
Providing training and instructions to team members.
Monitoring work processes.
Conducting inspections during the work process, not after.
Ensuring compliance with regulations and industry standards.
🧰 Example of QA in Construction:
Setting wiring standards before installation:
Type and size of wires to be used.
Proper installation procedures.
Training electricians to follow these standards.
Goal: Prevent issues like incorrect wire sizes or poor connections before they happen.
🔧 Quality Control (QC)
Definition: QC is the process of identifying, checking, and correcting defects in the final product or output.
Focus: It is product-based, ensuring the finished product meets set standards.
Timing: Done after QA, during or after work completion.
Approach: It is a corrective tool used to detect and fix mistakes.
🔍 Key QC Activities:
Visual inspections of the finished work.
Testing using tools (e.g., multimeters) to verify performance.
Checking compliance with codes and safety regulations.
Creating checklists and test reports to verify outcomes.
🧰 Example of QC in Construction:
After wiring is installed, the QC team:
Inspects the installation for visible defects.
Tests circuits to ensure they function correctly.
Ensures grounding and protection are done according to code.
If issues are found, they are corrected before project handover.
