  • Find anomalies
  • Improve the software product
  • Consider alternative implementations
  • Evaluate conformance to standards and specifications

The walk-through is similar to an inspection but is typically conducted less formally. The walk-through is primarily organized by the software engineer to give his teammates the opportunity to review his work, as an assurance technique.

Audits

The purpose of a software audit is to provide an independent evaluation of the conformance of software products and processes to applicable regulations, standards, guidelines, plans, and procedures. The audit is a formally organized activity, with participants having specific roles, such as lead auditor, another auditor, a recorder, or an initiator, and includes a representative of the audited organization. The audit will identify instances of nonconformance and produce a report requiring the team to take corrective action.

While there may be many formal names for reviews and audits such as those identified in the standard (see IEEE1028- 97), the important point is that they can occur on almost any product at any stage of the development or maintenance process.

Practical considerations

Software quality requirements

Influence factors

Various factors influence planning, management, and selection of SQM activities and techniques, including:

  • The domain of the system in which the software will reside (safety-critical, mission-critical, business-critical)
  • System and software requirements
  • The commercial (external) or standard (internal) components to be used in the system
  • The specific software engineering standards applicable
  • The methods and software tools to be used for development and maintenance and for quality evaluation and improvement
  • The budget, staff, project organization, plans, and scheduling of all the processes
  • The intended users and use of the system
  • The integrity level of the system

Information on these factors influences how the SQM processes are organized and documented, how specific SQM activities are selected, what resources are needed, and which will impose bounds on the efforts.

Dependability

In cases where system failure may have extremely severe consequences, overall dependability (hardware, software, and human) is the main quality requirement over and above basic functionality. Software dependability includes such characteristics as fault tolerance, safety, security, and usability. Reliability is also a criterion which can be defined in terms of dependability (ISO9126).

The body of literature for systems must be highly dependable (“high confidence” or “high integrity systems”). Terminology for traditional mechanical and electrical systems which may not include software has been imported for discussing threats or hazards, risks, system integrity, and related concepts, and may be found in the references cited for this section.

Integrity levels of software

The integrity level is determined based on the possible consequences of failure of the software and the probability of failure. For software in which safety or security is important, techniques such as hazard analysis for safety or threat analysis for security may be used to develop a planning activity which would identify where potential trouble spots lie. The failure history of similar software may also help in identifying which techniques will be most useful in detecting faults and assessing quality.

why is communication effective
Dakolo Reply
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

because it helps many people around the world to understand how to interact with other people and understand them well, for example at work (job).

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills

hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities. before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

continue.. sometimes due to these physical problems..the diagnosis may be misdiagnosed. treatment for autism. well it depends on the severity. since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective
Jharna
results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
