QA is “the planned and systematic order of events that provides assurance regarding the quality of the product or service”.
Quality Assurance is “planning-centric” and focuses on the system as a whole. It defines “what needs to be done to assure quality”. The assurance of quality begins with requirements generation and cascades, in stages, throughout the products or services life-cycle.
The goal of QA is to implement strategies and methodologies that limit the introduction of variation and error into production and service processes. These strategies and methods are documented in a Quality Assurance Plan.
Standards and requirements must be set and data collected and evaluated to "assure" that the expected results are being produced.
Implementing QA processes creates the Quality Management System. This system of management describes the elements necessary to plan, implement, and assess the effectiveness of QA & QC activities.
A Quality Management System establishes many functions including:
QA Plans are typically documented procedures. These procedures define the agreed upon best way to accomplish tasks where the resulting output meets or exceeds customer expectations. Customers can be either internal or external.
Quality Assurance Is Prevention - Quality Control Is Detection
QA is the planning that you need to put into place to prevent quality problems from occurring.
Quality, and quality improvement, are critical-to-customer-satisfaction. Without quality business survival is always in jeopardy! Therefore, a key objective of all businesses is to produce consistent and predictable results. Without quality assurance this is impossible!
If all of the bakers in a baking plant each had their individual recipes and methods of baking chocolate chip cookies- it's highly unlikely that the baked cookies would be consistent or predictable.
Without defined recipes and processes excessive variation will exist leading to inconsistent results. Customers would not know what to expect and will not be satisfied.
Variation within most business processes is EVIL!
Constant resources must be applied to understand and reduce it. Variation is the cause of inconsistency. If you are not consistent you are unpredictable! Excessive variation is almost always the initiator of a quality improvement event.
QA allows you to deliver internal benefits to the company and workforce and external benefits to the customer and community.

A Quality Control Plan is a documented description of the activities needed to control a process or product. The objective of a QCP is to minimize variation.
