1.QA is process oriented while QC is product oriented.
QA deals in developing processes and systems that aling with QMS.
QC on the other hand deals with monitoring products.
For example, a QA engineer would develop a quality plan based on customer requirements and the QC engineer would monitor and ensure that all requirements of the quality plan are met by the product during manufacturing.
A QA engineer may be involved in developing packagung & shipping requirement or be involved in providing quality specifications to purchasing. The QC engineer would only be focussed on making sure product meets the requirements of quality plan as set by QA.
2.QC is a part of QA, it's mean QA is wider that QC.
QC only check and make sure for today purpose only, but QA must ensure for future (after sales service, customer communication, etc).

3.quality assuarance is process oriented and it refers to all the planned and systematic activities implemented within the quality system that can be demonstrated to provide confidence that a product will fulfill requirements for quality while quality control is product oriented and is the operational tecnics and activities used to fulfill requirements for quality
4.hello
you are asking a QA Engineer can be a better person than the QC engineer in view of quality is concerned ?
yes my bro
its all depends on you that how much you have knowledge of your field and how u are utilizing your skills.
QA having more broader scope than QC.
Qc is a last process of QA.
QA is overall development and management process whlie QC is checking at the end of some development process.
hence if you choose QA as your carrier than u will be a good engineer
5.QA is more important that QC because QA ensures that the processes required to implement the QC are set and contolled in a way that QC is done in a way that is aligned with the high level requirements and policy of the business and organization. I can say that the QA person is more business oriented and the QC person is more technical and engineering oriented who can easily be deviated from the main purpose of the work required if the QA is not doing his work properly
6.Me i will not want to agree with the fact that QA is better that QC or QC is better than QA because the contribution of both of them in a project or quality management system will eventually produce a products or deliverables that will meet customer satisfaction. It is only that one comes after the other. May be i should use this medium to differeciate between the two. By definition, quality assurance is the process of verifying or determining whether product or services meet or exceed customer satisfaction. It has five cycles and they are 'Plan, do, check and act'. Quality assurance team plans on how to produce a product or service that will meet a customer satisfaction at the end of the day. After planning, execution takes place and deliverables are checked for conformity or variance. Any abnormality is then acted upon by the team for correction. Quality control on the other hand is a process employed to ensure a certain level of quality in a product or service. The goal of a quality control team is to identify products or services that do not meet a company’s specified standards of quality. If a problem is identified, the job of a quality control team or professional may involve stopping production or implementation temporarily. Depending on the particular service or product, as well as the type of problem identified, production or implementation may not cease entirely. Simply put, quality assurance ensures a product or service is manufactured, implemented, created, or produced in the right way; while quality control evaluates whether or not the end result is satisfactory
7.Quality Control is a system of routine technical activites,
to measure and control the quality of the inventory as it is being developed.
Quality Control includes general methods such as accuracy
checks on data acquisition and calculation and the use of
approved standardised procedure for emission calculations,
measurements, estimating uncertainites, archiving
informations and reporting.
Quality Assurance: Includes a planned system of review
procedures conducted by personal not directly involved in
the development process preferably by third parties should
be performed upon the finalized inventory after the
implementation of QC Process.
8.Quality Control refers to quality related activities associated with the creation of project deliverables. Quality control is used to verify that deliverables are of acceptable quality and that they are complete and correct. Examples of quality control activities include deliverable peer reviews and the testing process.
Quality Assurance refers to the process used to create the deliverables, and can be performed by a manager, client, or even a third-party reviewer. Examples of quality assurance include process checklists and project audits. If your project gets audited, for instance, an auditor might not be able to tell if the content of a specific deliverable is acceptable (quality control). However, the auditor should be able to tell if the deliverable seems acceptable based on the process used to create it (quality assurance). That's why project auditors can perform a quality assurance review on your project, even if they do not know the specifics of what you are delivering.
9.
Quality Assurance deals with proactive plan and techniques with regard to process and hence gives confidence about the product quality.
Quality control iis a post opeartion activity and decides what is ok and what is not.
Quality assurance is the set of activities to be followed to ensure the quality.
While Quality control is a set of activities to evaluate the product.
QA has to do with ensuring that the right process or step is followed.That is doing the right thing by the people.This is building quality in the process,product and people while QC is all about seeing if the right thing is done.
QA: It is set of procedures intended to ensure that product/service under development meets specified requirements.
QC: It is a set of actvities focus on finding defects in specific deliverables,in order to ensure the product/software meets the quality criteria and requirements of the client.
10.The difference between QA vs QC
• The US EPA differentiates between QC and QA in the
following way:
** QC is a `system of activities to provide a quality
product ' and QA is a `system of activities to provide
assurance that the QC system is performing adequately.
In other words, QA is QC for QC'.**
• QC ensure that the analytical system is 'in control '(i.e.
operating within specified limits).
• QA ensure that the quality control procedures or system is in working correctly.
I think:
QA is process related and QC is the actual testing of the software
QA focuses on building in quality....and hence preventing defects.
QC focuses on testing for quality...and hence detecting defects
QA focuses on building in quality....and hence preventing defects.

Quality Assurance makes sure you are doing the right things, the right way.
Quality Control makes sure the results of what you've done are what you expected
Quality Control makes sure the results of what you've done are what you expected
While quality control should be done by a limited number of people, everyone working in the plant should be part of a quality assurance program.
The five QA/QC elements
QA programs generally address five QA/QC
elements, namely:
1. Accuracy -the degree of agreement of a
measurement with an accepted reference or
true value.
2. Precision - a measure of the mutual agreement
among individual measurements of the
property, usually under prescribed similar
conditions.

3. Completeness - a measure of the amount of
valid data obtained from a measurement
system compared to the amount that was
expected to be obtained under correct normal
conditions.
4. Representativeness -the degree to which data
accurately and precisely represent a
characteristic of a population or parameter
variations at a sampling point, a process
condition, or an environmental condition.
5. Comparability -the confidence with which one
data set may be compared to another.
Production of long-life low acid products especially, involves high risks and potential failure. This demands a highly efficient performance at each “operation unit” stage.
Operational procedures must be documented and skilfully supervised.
Control of the production process is much more effective and much more important than the control of the final product. Suitable means of assuring the production of safe and wholesome products of adequate quality should be introduced in every task of operation.
This is the intent of quality assurance: To prevent any deviation from the stated quality specifications and to integrate specifications
In without quality control procedures in place,
laboratories cannot hope to remain in-control, and
without quality assurance procedures in place,
they cannot ensure that they are in-control.
• Also, without formal reporting of the QA/QC
results, laboratories cannot demonstrate to data
users that they are producing high quality
analytical data. It is therefore very important that
Quality Assurance Programs adopt QA/QC
reporting as a regular laboratory function.
11.Difference between quality assurance , quality control vs sixsigma
1. Quality assurance is implementedduring process of design,development,validation,product realisation areas .
2. Quality control is implemented during process of inspection,confirmancies,audits,improvements areas .
3. Six sigma is a quality measure on a six point scale of quality achivement in the due process of quality assurance,implementation and control
All are the tools to achieve the quality objective losses and achive the required quality standards and reduce loss of manpower,materials,process time , and to achive a defectless process quality
12.QA ensures that all processes required to implement QC are controlled.QA is a component of QC and QC involves all phases of QSM. QC also checks whether a product meets all produts requirements and specification.QA is an oriented [process and loooksat the process of producing a product.
