Whenever you find a bug or ERROR, be positive about the situation. Finding inconsistencies is an essential part of working QUALITY control.

Whenever you find bugs or ERRORS, be sure to DOCUMENT them and communicate them to your superiors so they can relay the information to the production team, who can adjust and modify their own procedures in order to ensure a bug-free product.

The role of a quality control specialist revolves around quality, but in reality, they play a significant role in resource and labour EFFICIENCY as well.

One of the core responsibilities of QC specialists is to analyze defect rates and compare them with benchmarks. If they are LACKING, quality control specialists can identify and suggest WAYS to MAKE them up to par, SAVING the organization time, money, and resources.

The quality CONTROL PROCESS does not end when the clock hits 5 p.m. In today's 24/7 world of production, it is imperative to have processes that guarantee consistency, no matter what shift it is produced on.

The key to working with workers across shifts is communication. The best way to keep things consistent from shift to shift is to put standardized processes into place so that each shift can seamlessly CARRY on where the last one left off. Moreover, every inspector should work on a shift at least once to GET a sense of the SCOPE of operations.

Using the right standards is key to quality control. As part of any quality control project, the FIRST STEP is to define quality and the standards that should be followed to achieve it. This is critical because, without it, we cannot establish BENCHMARKS for any future inspections. A quality control specialist must comprehend the IMPORTANCE of adhering to RIGOROUS quality control standards and protocols. 

The quality control process is stressful, and it is often done under strict deadlines. To be EFFECTIVE, quality control managers must balance the demands of their role with the deadlines of the company and their clients.

• First, they would flag the issue as soon as POSSIBLE so that they could begin taking corrective action. 
• Once the defect has been identified, they gather as much information as possible regarding the defect, its potential solutions, and how each will affect TIMELINES. 
• By doing so, they can present the most viable options to their stakeholders in the most thorough manner possible, so that the best decision can be made to mitigate the damage.

A good QC specialist would rather miss a deadline for a high-quality, safe product than DELIVER a defective one on the schedule.

Process qualification ensures your MANUFACTURING processes are able to produce a certain volume consistently over time. In the absence of these, production processes will break down, leading to missed DEADLINES and unfulfilled orders. As part of the process qualification, we evaluate the facility, MATERIALS, hardware/equipment, software applications, PERSONNEL, RISK, and quality monitoring tools.

Following are a few of the most important quality management principles to focus on:

• Customer Focus: Quality management aims to meet and exceed the needs or expectations of customers.
• Leadership: Leaders create a sense of unity and commitment among staff and ensure that the quality objectives of an ORGANIZATION are met.
• Engagement of People: A thriving organization requires people who are empowered, competent, and engaged to deliver value. A high-performing, empowered and engaged workforce enhances the organization's ability to create value.]
• PROCESS Approach: By understanding and managing activities as interconnected processes that function as a cohesive system, we can achieve more predictable and consistent results more effectively.
• Improvement: Improved performance is a priority for SUCCESSFUL organizations. A continuous focus on improvement is therefore crucial.
• Evidence-based Decision Making: Data-driven decisions have a better CHANCE of producing the desired results than those based on guesswork and intuition. Results are more likely to be ACHIEVED when decisions are made based on data analysis and evaluation.
• Relationship Management: Organizations must manage their relationships with stakeholders, such as suppliers, for sustained success.

Load TESTING and system testing are among the most common types of quality control testing.

• Load testing: Performing load tests will allow you to understand how a system will perform under real-life load conditions. Load testing measures how well a system performs for example when it experiences high demand, such as multiple users at the same time.
• STRESS testing: A stress test is MEANT to DETERMINE the maximum capacity of a system under heavy load conditions such as Slashdot effect, DDoS attack, or other scenarios. The test verifies the system's RELIABILITY and stability.

Quality CONTROL specialists leverage a variety of tools for analytics, compliance monitoring, customer SATISFACTION management, and more. New technology is introduced every year, but some tools have become industry standards. In the long run, quality control specialists must be flexible and willing to learn new technology.

Almost all quality control managers and specialists have their preferred methods or tools for inspecting quality. Seven main tools for quality control are Pareto CHART (80/20 Rule), Stratification (Divide and Conquer), Cause-and-effect diagram (“fishbone” or Ishikawa diagram), Scatter diagram (Shewhart Chart), Check Sheet (Tally Sheet), HISTOGRAM, and Control chart. Known as the Seven Basic Tools of Quality, these tools could be applied by anyone with a very basic understanding of STATISTICS and were simple to apply to resolve quality-related complex issues. Good candidates should be able to explain the tools that they use most frequently.

Following are the different Software Control VIEWS:

• User View: A product's quality is determined by how well it MEETS the needs of the user.
• Product View: A product's quality is determined by its characteristics.
• Value-based View: A product's quality is determined by the NUMBER of CUSTOMERS WILLING to pay for it.
• Development View: A product's quality is determined by its conformance to its requirement specifications.

In determining the software quality of a system or a product, there are different FACTORS as given below:

• Usability: How easy it is to USE or OPERATE the software.
• Portability: The capability for a software product to be used in different environments or locations.
• Maintainability: The ease of updating and maintaining a software product.
• Reliability: How long a product can operate without any downtime or defects.
• Efficiency: A product's ability to meet the requirements EFFECTIVELY or how WELL it performs.

PDCA (Plan-Do-Check-Action) MODEL/cycle is also known as PDSA ( Plan-Do-Study-Act), the "Deming Wheel," and "Shewhart Cycle". A PDCA cycle fosters the methodical, rigorous IMPLEMENTATION of solutions to problems. It is a four-step process that assists teams in avoiding recurring mistakes and improving development processes. In the same way that a circle is infinite, PDCA should be repeated indefinitely to improve continuously.

• Plan: The first step is to identify and understand your opportunity or problem, and then plan how to proceed. Planning takes a significant amount of your team's time, depending on the project's size. A proper plan usually consists of smaller steps so that there is a lower possibility of failure.
• Do: Once you have agreed on a plan, it is time to take action. In this step, you put into practice all the things you considered in the previous stage. At this stage, unforeseen problems can occur. In an ideal scenario, you should first test your plan on a small scale and in a controlled environment.
• Check: If you wish to develop a clear plan, avoid making the same mistakes, and use continuous improvement effectively, you should pay close attention to the check phase. You need to examine your plan's execution result and determine whether it was successful. MOREOVER,  your team will be capable of identifying problematic parts of the current process and eliminating them in the future. TRY experimenting with more changes, and repeat the Do and Check phases. If something goes wrong during the process, you need to figure out the problem's root cause. In any case, if your original plan doesn't work, you ought to start over with the planning phase.
• Act: The previous steps were to develop, apply, and check your plan. Now it's time to act. As long as everything appears to be WORKING well and your team was successful in achieving the original goals, you can proceed and implement your original plan. In this instance, your PDCA model becomes your new benchmark. Whenever you repeat a standardized plan, ask your team to go through all steps again and improve the care.

Different standards are developed and IMPLEMENTED by organizations around the world to improve software quality. When releasing products, SEVERAL ISO standards must be met. Some of the characteristics as PER ISO standards are environmental management, risk management, quality management, auditing. Other ISO standards for quality control include RELIABILITY, USABILITY, efficiency, and maintainability.

Quality control entails several specific characteristics, including:

• ADOPTING a different set of PROCESSES.
• To DELIVER a high-quality product.
• Providing quality PRODUCTS to customers at an affordable price.
• Improving quality by implementing processes from different organizations and standards.
• To ensure proper execution of the test plan.
• Make sure the execution is PLANNED with the proper review process.
• The effectiveness and efficiency with which a product or system can be modified in order to improve, correct, or adapt to a changing environment.
