Quality: Conformance to explicit and implicit requirements and adherence to defined standards.
Quality Control: Are set of reactive activities (testing, inspection, technical reviews) to uncover defects injected into the product by people and/or processes.
Quality Assurance: are set of preventive activities that prevent defects to be injected into the product/project by people and/or processes.
Quality Improvement: Lessons learnt throughout the project/product life cycle when something went wrong or well. Adopting practices/processes (for future project/product life cycles) that worked well and avoiding those that created a mess. E.g. decide on whether to adhere to inspection of artifacts produced in different life cycle phases or it can be skipped if that not worked (according to objectives set when project is initiated) in some specific cases.
Measuring Quality: The degree to which the conformance to explicitly stated requirements is achieved. Numerically, number of client reported issues, number of defects uncovered during testing, inspection, reviews, effort variance in completing activities.
