What is quality
The document discusses quality assurance and quality control. Quality assurance is a proactive process that focuses on processes and preventing defects by understanding requirements upfront and developing plans to meet them. Quality control is reactive and focuses on operational activities like inspection and testing to identify defects and ensure deliverables meet requirements. The quality control process receives input from quality assurance, and if defects are found during quality control, quality assurance will investigate and implement corrective actions to prevent reoccurrence.
Quality check
Quality control procedures are important to ensure products meet defined quality criteria and customer expectations. This involves testing units to check if they are within specifications and determining if corrective actions are needed in the packing and shipping process. Good quality control helps companies satisfy customers with better products. It is also important to consider customer feedback, which can be used as testimonials to motivate employees or improve products based on customer experiences. Proper inspection and cleaning of products before shipment helps check quality.
Qa vs qc (yes)
QA is a set of proactive activities that focuses on processes to prevent defects by identifying weaknesses, while QC is a set of reactive activities that focuses on identifying and correcting defects in finished products. The goal of QA is to improve development processes so no defects arise, while the goal of QC is to identify defects after development before release.
The concept of quality assurance
This document discusses quality assurance and its role in manufacturing. Quality assurance aims to prevent defects and ensure products and services meet customer requirements. It involves implementing systematic processes to verify that quality standards are fulfilled. During World War I, mass production led to quality issues, so inspectors were introduced to identify problems. Later, experts like Deming and Juran helped develop the modern concept of quality assurance. Quality assurance managers work to establish procedures and monitor quality against targets to ensure customer expectations are met.
Validation and verification
Validation determines if the correct product is being built by checking if customer needs are met, through subjective processes like modeling and user evaluation. Verification determines if the product is being built correctly according to procedures and specifications, through objective measurement and analysis of the development process, for example inspections of quality requirements. Both are important but serve different purposes - validation ensures the right product is made while verification ensures it is made correctly.
Implementation of the quality system
This document discusses implementing quality systems, measuring cost of quality (COQ), and using statistical process control (SPC) tools to improve quality. It states that COQ is the cost of producing defective products, not the cost of producing good products. Measuring COQ is important for organizations to reduce costs and provide quality at lower prices. One method for reducing COQ is through the use of SPC tools. The objectives are to benchmark quality systems, measure COQ and quality improvements using SPC tools, and develop a framework for ongoing COQ measurement. The methodology involves defining quality systems, reviewing literature on COQ and SPC, analyzing COQ, conducting SPC analysis, and developing corrective action plans.
Software quality management
Quality management involves ensuring that products and services meet customer requirements and provide satisfaction. It can be achieved through quality assurance and quality control. Quality assurance focuses on improving the development process, while quality control tests whether the final product or service works properly. The key difference is that quality assurance is preventative and examines the development process, while quality control is detective and evaluates the final product or service. Implementing quality practices leads to benefits like increased consistency, efficiency and profits as well as better customer satisfaction.
JF608: Quality Control - Unit 6
The document discusses different categories of quality costs: presentation costs, appraisal costs, internal failure costs, and external failure costs. It provides examples of costs that fall under each category and explains how tracking quality costs can help companies identify areas for improvement and prioritize quality initiatives. Quality costs can be optimized by finding the right balance between prevention costs and failure costs.

Quality assurance and quality control are related but distinct concepts. Quality assurance refers to planned and systematic activities implemented in a quality system to provide confidence that quality requirements will be fulfilled, while quality control refers to procedures intended to ensure a product or service adheres to defined quality standards. The document outlines key steps in a quality assurance process including identifying organizational goals and customers, obtaining feedback, and making continuous improvements. It also describes a quality control system with incoming, in-process, and outgoing inspection stages to maintain quality throughout production.
Elements of Quality Management System
This document outlines the key elements of a quality management system, including a quality policy, quality objectives, quality manual, organizational structure, data management, purchasing processes, customer satisfaction, continuous improvement, quality instruments, and document control. The quality policy is a statement by top management regarding product quality expectations. Quality objectives define measurable goals for achieving the quality policy. The quality manual details how the quality management system operates. The organizational structure links quality responsibility to executive levels. Data management develops architectures and procedures for information lifecycles. Purchasing and other processes are also covered.

Quality Management
Japan faced criticism for low quality products in the 1960s but implemented effective quality management that transformed its reputation. Quality management ensures consistency through planning, assurance, control, and improvement. It uses tools like control charts, histograms, and flow charts. Customer perceptions of quality are measured using SERVQUAL criteria of reliability, assurance, tangibles, empathy and responsiveness. International standards like ISO 9000 define quality systems. Total quality management involves all employees continuously improving processes, products, services and culture through principles like customer focus, communication and fact-based decision making. The PDCA (plan-do-check-act) cycle is used for process improvement. Six Sigma aims to define, measure, analyze, improve and control quality within processes.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

- 1. 99 problems but a test ain’t one Product Testing
- 2. Product Testing Product Testing is the practice of thoroughly evaluating the usability of a product before beginning manufacturing of the end product. Using different types of testing applied at different stages of the product development process helps the development team understand the purpose of each test and consider how best to capture data. Each test requires clear objectives, approaches and types of modelling.
- 3. How do we make a good test? Quality Assurance - define and improve quality processes and procedures to ensure quality Quality Control - Evaluate the quality using the QA tools, as well as comparison to customer’s expectations Testing - Find and report bugs and defects in the product.
- 4. The 4 Test Buckets:Review Exploratory - Let’s understand this feature and refine our test as we go. Assessment - Checklist of tasks and steps Validation - Are we building the right product? Verification - Are business requirements Satisfied? Are we building the product right?
