Define quality assurance and describe the unique tools and techniques used for quality assurance processes.
Answer:
The quality assurance process is comprised of all the activities and actions required to ensure that the
project meets the quality standards outlined during the quality planning phase. Quality assurance is
typically overseen by a quality assurance department, a group responsible for making sure that a project
satisfies all of the processes needed to meet stakeholder requirements.
The tools and techniques used as part of the quality planning process can also be used during quality
assurance. Two new tools are also used in the quality assurance process, specifically quality audits and
process analysis.
Quality audits are activities designed to review other quality management procedures as well as to
identify potential lessons learned. In a quality audit, the review is conducted in either scheduled or
random fashion by trained personnel from within the organization or, in some cases, by qualified
third-party auditors. Quality auditors typically examine a number of different project facets looking for
ineffective or inefficient policies, processes, or procedures. Quality auditors may start with an established
checklist and rate the various project facets evaluated.
Another tool used in the quality assurance process is a process analysis, which examines not what is done
but how it was done.

Describe the ISO 9000 family of standards. In what ways can ISO 9000 help an organization?
Answer:
In 1987, the International Organization for Standardization instituted the voluntary ISO 9000 standard.
ISO 9000 is a generic management systems standard, which signifies that it is applicable to any industry
or organization, including information systems focused enterprises. ISO 9000 is one of the most popular
quality standards in the world. Thousands of organizations have adopted it and more continue to do so
on a regular basis.
The ISO 9000 standard is primarily concerned with quality management, specifically the processes that
the organization performs to satisfy customer quality requirements, to satisfy regulatory requirements, to
enhance customer satisfaction, and finally to provide for continual improvement in performance of these
objectives. ISO 9000 is based on quality management principles that focus on different aspects of an
organization's purpose.
As a family of standards, ISO 9000 can be customized and applied to various industries. One example
specific to information systems development is the problem of software configuration management. In
the process of building computer software, change frequently occurs during the development stage.
Despite the intention to control factors like scope creep, user requirements frequently need to be modified
as a project moves forward. Software configuration management is a set of activities designed to help
manage or control such changes by assisting developers or project managers in identifying those work
products that are most likely to change, establishing relationships among work products so that the
developer can anticipate any associated changes that will also need to be made, defining ways to manage
different versions of work products, and reporting on changes that have been made. ISO 9000 can
provide guidance to help a firm establish documented procedures for controlling such changes.

Describe cost of quality and its major categories. How can organizations decrease the costs associated with
software quality?
Answer:
The cost of quality is comprised of both the costs to improve or ensure quality measures and the costs
associated with a lack of quality. More specifically, the cost of quality might represent the amount of
money a business could lose from a products or services not being done well the first time around. These
costs can include anything from rework to lawsuits resulting from poor quality.
The costs of quality are divided into two major categories: conformance and nonconformance. The cost of
conformance is the amount spent on achieving high-quality products. This category of quality costs is
further divided into prevention and appraisal costs. Prevention costs are those associated with
preventing any defects before they happen, whereas appraisal costs are those incurred in assuring
conformance to quality standards. The cost of nonconformance includes all the expenses that result when
things go wrong. This category of quality costs is also further divided into two subcategories, internal
failure costs and external failure costs. Internal failure costs occur before the product is sent to the
customer, whereas external failure costs arise from product failure at the customer's location.
The best strategy to decrease the costs associated with software quality involves:
·Avoiding any failure costs by driving defects to zero
·Investing in prevention activities to improve quality
·Reducing appraisal costs as quality improves
·Continuously evaluating and altering preventive efforts for more improvement

Briefly outline the achievements of the most well-known quality management pioneers.
Answer:
W. Edwards Deming, who received a PhD in mathematics from Yale University in 1928, is probably best
known for his 14 points of quality. In addition to his academic appointments as a statistician and quality
expert, as well as his numerous books, Deming achieved worldwide prominence and became known as
the "prophet of quality." He played a significant role in the economic resurgence in Japan following
World War II, where he served as a consultant to Japanese industry. This role is particularly noteworthy
because Deming's management philosophies had a significant impact on Japanese business thinking
and, as a result, on global trade as corporations competed on quality.
Dr. Joseph Juran is often credited with adding the human element to what was previously a statistical
view of project quality. Dr. Juran is further credited with the Pareto Principle, or the 80/20 rule, a quality
tool. Juran authored both the Quality Control Handbook and the Juran Trilogy. The Juran Trilogy was
accepted worldwide as a model for quality management; it focused on the three areas of quality
planning, quality improvement, and quality control.
Philip B. Crosby dedicated his career to convincing managers that preventing problems was cheaper
than fixing them. In his groundbreaking work Quality is Free (1979), Crosby defined quality in an
absolute way so that companies could readily see whether or not quality existed in the workplace using
four absolutes of quality management.
Kaoru Ishikawa is best known for his cause-and-effect diagram, also called a fishbone diagram, a
diagramming technique used to explore potential and real causes of problems. The fishbone diagram
typically organizes problems into categories relevant to the industry. Ishikawa was also known for his
insistence that quality could always be taken one step farther. Ishikawa expanded on Deming's
plan-do-check-act model to create an actionable list of six items.
