This document discusses software quality assurance. It defines software as computer programs, procedures, and documentation related to operating a computer system. Software quality is defined as meeting requirements and user needs/expectations. Quality factors include correctness, reliability, efficiency, integrity, usability, maintainability, flexibility, testability, portability, reusability, and interoperability. Software quality assurance is a planned set of actions to provide confidence that software development/maintenance conforms to requirements and schedules/budgets. The objectives of SQA are to assure acceptable confidence in conforming to functional/managerial requirements during development and maintenance. Three principles of QA are to know what is being done, know what should be done, and know how to
Requirements analysis, also called requirements engineering, is the process of determining user expectations for a new or modified product. These features, called requirements, must be quantifiable, relevant and detailed. In software engineering, such requirements are often called functional specifications. Requirements analysis is an important aspect of project management.

This ppt is done by my dear classmate Sap, almost each ppt I have uploaded is copied from net and other sources.I hope this will b a little useful for students..
This lecture is about the detail definition of software quality and quality assurance. Provide details about software tesing and its types. Clear the basic concepts of software quality and software testing.
Software Engineering is the set of processes and tools to develop software. Software Engineering is the combination of all the tools, techniques, and processes that used in software production. Therefore Software Engineering encompasses all those things that are used in software production like :
Programming Language
Programming Language Design
Software Design Techniques
Tools
Testing
Maintenance
Development etc.
These days object-oriented programming is widely being used. If programming languages will not support object-orientation then it will be very difficult to implement object-oriented design using object-oriented principles. All these efforts made the basis of software engineering.
Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. I hope this ppt will help u to learn about software testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. What is Software?
According to the IEEE
Software is:
“Computer programs, procedures, and possibly
associated documentation and data pertaining to
the operation of a computer system”.
3. What is Software Quality ?
According to the IEEE
Software quality is:
1. The degree to which a system, component, or process
meets specified requirements.
2. The degree to which a system, component, or process
meets customer or user needs or expectations.
According to Pressman
“Conformance to explicitly stated functional and performance
requirements, explicitly documented development standards, and
implicit characteristics that are expected of all professionally
developed software”.
4. What is Software Quality?
“Achieving high levels of user satisfaction, portability,
maintainability, robustness, and fitness for use” by
Dr. Barry Boehm.
Quality means “conformance to user requirements”
by Phil Crosby.
Edwards Deming considers quality to be “striving for
excellence” in reliability and functions by continuous
improvement in the process of development, support
by statistical analysis of the causes of failure.
5. What is Software Quality?
Watts Humphrey, of the SEI, tends to speak of
quality as “achieving excellent levels of fitness for
use, conformance to requirements, reliability and
maintainability.”
James Martin said that software quality means being
on time, within budget and meeting user needs
Tom McCabe, the software complexity specialist,
defines quality as “high level of user satisfaction and
low defect levels, often associated with low
complexity
6. What is Software Quality?
John Musa of Bell Laboratories states that
quality means combination of “low defect
levels, adherence of software functions to
users needs, and high reliability”
Bill Perry, head of Quality Assurance Institute
has defined quality as “high levels of user
satisfaction and adherence to requirements”.
7. Why Quality is Important?
Quality is critical for survival and success.
Customers demand quality.
Everybody seems to understand quality.
Everybody wants quality
Everybody has a different perception of
quality.
Essentially quality means satisfying
customer.
8. Why Quality is Important?
Why business should be concerned with
quality:
– Quality is competitive issue now
– Quality is a must for survival
– Quality gives you the global reach
– Quality is cost effective
– Quality helps retain customers and increase
profits
– Quality is the hallmarks of world-class business
9. Importance of Software Quality
Software is a major component of computer systems
(about 80% of the cost) – used for
– communication (e.g. phone system, email system)
– health monitoring,
– transportation (e.g. automobile, aeronautics),
– economic exchanges (e.g. ecommerce),
– entertainment,
– etc.
Software defects are extremely costly in term of
– money
– reputation
– loss of life
10. Importance of Software Quality
Several historic disasters attributed to software
– 1988 shooting down of Airbus 320 by the USS Vincennes cryptic and
misleading output displayed by tracking software
– 1991 patriot missile failure inaccurate calculation of time due to computer
arithmetic errors.
– London Ambulance Service Computer Aided Dispatch System – several
deaths
– On June 3, 1980, the North American Aerospace Defense Command
(NORAD) reported that the U.S. was under missile attack.
– First operational launch attempt of the space shuttle, whose real-time
operating software consists of about 500,000 lines of code, failed
synchronization problem among its flight control computers.
– 9 hour breakdown of AT&T's long distance telephone network caused by
an untested code patch
11. Software Quality Factors
Correctness
– accuracy, completeness of required output
– upto-dateness, availability of the information
Reliability
– Minimum failure rate
Efficiency
resources needed to perform software function
Integrity
– software system security, access rights
Usability
– ability to learn, perform required task
12. Software Quality Factors

Defect Origins Yes Yes
Defect Severity Yes Yes
Defect Removal Efficiency Yes Yes
Product Complexity Yes Yes
Project Reliability Yes Yes
Project Maintainability Yes Yes
Project schedules Yes Yes
Project budgets Yes Yes
Portability Yes Yes
Conformance to requirements No Yes
User Satisfaction No Yes

Robustness No No
14. Software Quality Challenges
The measures for quality differ from project to project
and organization to organization
– Quality measures used for small systems may not be
appropriate for the large ones.
Criteria for quality vary as a function of the specific
characteristics of the project, the needs of the users
and stakeholders, and the application requirements
of the system and software.
– Criteria for quality applied to real-time applications are not
always relevant when dealing with systems that are not
real-time.
15. What is Software Quality
Assurance?
According to the IEEE
Software quality assurance is:
1. A planned and systematic pattern of all actions
necessary to provide adequate confidence that an
item or product conforms to established technical
requirements.
2. A set of activities designed to evaluate the process
by which the products are developed or
manufactured. Contrast with: quality control.
16. What is Software Quality
Assurance?
According to D. Galin
Software quality assurance is:
“A systematic, planned set of actions necessary to provide
adequate confidence that the software development process
or the maintenance process of a software system product
conforms to established functional technical requirements
as well as with the managerial requirements of keeping the
schedule and operating within the budgetary confines.”
17. Objectives of SQA
Development:
Assuring an acceptable level of confidence that the software will conform to
functional technical requirements.
Assuring an acceptable level of confidence that the software will conform to
managerial scheduling and budgetary requirements.
Initiation and management of activities for the improvement and greater
efficiency of software development and SQA activities.
Maintenance:
Assuring an acceptable level of confidence that the software maintenance
activities will conform to the functional technical requirements.
Assuring an acceptable level of confidence that the software maintenance
activities will conform to managerial scheduling and budgetary requirements.
Initiate and manage activities to improve and increase the efficiency of software
maintenance and SQA activities.
18. Three General Principles of QA
Know what you are doing
Know what you should be doing
Know how to measure the difference
19. Three General Principles of QA
Know what you are doing
understand what is being built, how it is being built
and what it currently does.
suppose a software development process with
– management structure (milestones, scheduling)
– reporting policies
– tracking
20. Three General Principles of QA
Know what you should be doing
– having explicit requirements and specifications
– suppose a software development process with
requirements analysis,
acceptance tests,
frequent user feedback
21. Three General Principles of QA
Know how to measure the difference
– having explicit measures comparing what is being
done from what should be done
– four complementary methods:
formal methods – verify mathematically specified properties
testing – explicit input to exercise software and check for
expected output
inspections – human examination of requirements, design,
code, ... based on checklists
metrics – measures a known set of properties related to
quality.
22. Software Quality Challenges
Complex Software requires different monitoring
procedures than trivial applications.
Quality criteria vary dramatically depending on the
phase of the project at which the evaluation takes
place
The measures of the quality must be specific to the
project being evaluated and must assess the
effectiveness of the entire development process, not
just individual segments.
23. Software Quality Challenges
Quality cannot be directly checked in the product; it
must planned right from the beginning.
Quality goals must be clearly defined, effectively
monitored, and rigorously enforced.
The project must focus on the quality issues of the
project from the beginning, ensuring that quality
criteria are consistent with defined requirements.
Quality must be planed into the project structure,
constantly evaluated, and corrections applied when
deficiencies are identified.
24. Changing View of Quality
Past Present
Quality is the responsibility of blue
collar workers and direct labor
employees working on the product
Quality is everyone’s responsibility,
including, white-collar workers, the
indirect labor force and the
overhead staff
Quality defects should be hidden
from the customers and
management
Defects should be highlighted and
brought to the surface for corrective
actions
Quality problems lead to blame,
faulty justification and excuses
Quality problems lead to
cooperative solutions
Corrections-to-quality problems
should be accompanied with
minimum documentation
Documentation is essential for
“lessons learnt” so the mistakes are
not repeated.
25. Changing View of Quality
Past Present
Increased quality will increase
project costs
Improved quality saves money and
increase business
Quality is internally focused Quality is customer focused
Quality will not occur without close
supervision of people
People want to produce quality
products
Quality occurs during project
execution
Quality occurs at project initiation
and must be planned for within the
project
26. Quality Control v/s Quality Assurance
Quality means meeting requirements and meeting
customer needs, which means a defect-free product
from both the producer’s and the customer’s
viewpoint.
Both quality control and quality assurance are used
to make quality happen.
Quality is an attribute of a product. A product is
something produced, such as a requirement
document, test data, source code etc.
27. Quality Control v/s Quality Assurance
Quality Assurance Quality Control
Quality Assurance (QA) is
the set of activities (including
facilitation, training,
measurement and analysis)
needed to provide adequate
confidence that processes
are established and
continuously improved in
order to produce products or
services that conform to
requirements and are fit for
use.
Quality Control (QC) is
defined as the processes and
methods used to compare
product quality to
requirements and applicable
standards, and the action
taken when a
nonconformance is detected.
28. Quality Control v/s Quality Assurance
Quality Assurance Quality Control
QA is an activity that
establishes and evaluates
the processes that
produce the products. If
there is no process, there
is no role for QA.
QC is an activity that
verifies whether or not the
product produced meets
standards.
29. Quality Control v/s Quality Assurance
Quality Assurance Quality Control
QA helps establish
processes
QC relates to a specific
product or service
QA sets up measurement
programs to evaluate
processes
QC verified whether
particular attributes exist,
or do not exist, in a
specific product or service
QA identifies weakness in
processes and improves
them
QC identifies defect for the
primary purpose of
correcting defects.
30. Quality Control v/s Quality Assurance
Quality Assurance Quality Control
QA is a management
responsibility, frequently
performed by a staff
function
QC is the responsibility of
the worker
QA evaluates whether or
not quality control is working
for the primary purpose of
determining whether or not
there is weakness in the
process
31. Quality Control v/s Quality Assurance
Quality Assurance Quality Control
Defining Processes Walkthrough
Quality Audit Testing
Selection of Tools Inspection
Training Checkpoint review
32. Impediments to Software Quality
Control
Quality control is often viewed as a police
action
IT is often considered an art
Unclear or ineffective standards and
processes
Lack of process training
33. Impediments to Software Quality
Assurance
Management does not insist on compliance to processes
Workers are not convinced of the value of processes
Processes become obsolete
Processes are difficult to use
Workers lack training in processes
Processes are not measurable
Measurement can threaten employees
Processes do not focus on critical aspects of products
34. Quality Assurance at each phase of
SDLC
Requirements Analysis Phase:
Three major activities that foster quality
– Measurement of process attributes
– Verification and Validation
– Management
Managing quality in the analysis stage is a
challenge.
35. Quality Assurance at each phase of
SDLC
Good Quality Requirements
– They are precise, with no room for
misinterpretation by users or implementers
– They specify just what the system must do, not
how to do it. They avoid specifying
implementation details
– They show conceptual integrity, building on a
simple set of facilities that interact well with each
other
36. Quality Assurance at each phase of
SDLC
Major management deficiencies in most
software development projects:
– Incorrect schedules
– Incorrect cost estimates
– Inadequate project accountability procedures
– Inadequate quality assurance procedures
– Imprecise goals and success criteria
37. Quality Assurance at each phase of
SDLC
Design phase:
A lack of quality in the design process can
invalidate good requirements specification
and can make correct implementation
impossible.
Industry practice shows that use of checklist
during design helps improve design quality.
