Definition:
QA is a set of activities for ensuring quality in the processes by which products are developed.
| QC is a set of activities for ensuring quality in products. The activities focus on identifying defects in the actual products produced. |
Focus on:
QA aims to prevent defects with a focus on the process used to make the product. It is a proactive quality process.
| QC aims to identify (and correct) defects in the finished product. Quality control, therefore, is a reactive process. |
Goal:
The goal of QA is to improve development and test processes so that defects do not arise when the product is being developed.
| The goal of QC is to identify defects after a product is developed and before it's released. |
How:
Establish a good quality management system and the assessment of its adequacy. Periodic conformance audits of the operations of the system.
| Finding & eliminating sources of quality problems through tools & equipment so that customer's requirements are continually met. |
What: Prevention of quality problems through planned and systematic activities including documentation.
| The activities or techniques used to achieve and maintain the product quality, process and service. |
Responsibility:
Everyone on the team involved in developing the product is responsible for quality assurance.
| Quality control is usually the responsibility of a specific team that tests the product for defects. |
Example:
Verification is an example of QA
| Validation/Software Testing is an example of QC |
Statistical Techniques:
Statistical Tools & Techniques can be applied in both QA & QC. When they are applied to processes (process inputs & operational parameters), they are called Statistical Process Control (SPC); & it becomes the part of QA.
| When statistical tools & techniques are applied to finished products (process outputs), they are called as Statistical Quality Control (SQC) & comes under QC. |
As a tool:
QA is a managerial tool

Overview: The Daily Scrum Meeting is held every day through the sprint. At the meeting, the Scrum team gathers to review and synchronize about the project status. In theory, each team member should provide his/her status based on three (03) Q: What did you do yesterday? What do you intend to do today? Is there any issues that blocks your work? # The participants should come prepared: Stop participants that don't come prepared and waste the meeting time. The team members should come prepared to share their updates. You should describe how to answer these questions effectively to increase the synchronization among the team members. The team members should know what is your expectations from them while answering these questions. # Validate that each individual describe the full picture: Validate that each individual can answer the 3 questions (Do not continue until you get the answers or the reasons for why he can't provide them). Validate that each tea...
