Introduction
The article outlines basis on which software quality metrics can be evaluated.
The goal of the presentation is to address software quality models and metrics
behind them.
The phases at which these models and metrics are applicable would be
analyzed.

Introduction cont.…
Software quality metrics would be analyzed in regard to;
The overview of the content presented by the authors in the article.
The change management in software development process.
The importance of change management in the context of software
development.
Software testing and quality parameters which should be considered in order to
ascertain quality of the software.

The content of the article
Different software quality models would be presented in order to determine which
best suites specific software.
To develop a quality product, the software should conform to given specifications.
All future aspects of the users should be translated into measurable characteristics if
software metrics has to be met adequately.
The article focuses on software quality metrics that system developers and
designers should address.

The content of the article cont.…
Some software metrics are unmeasurable, and this makes it difficult to control an
unmeasurable aspect.
Unmeasurable parameters are brought about by attributes which are un-tangible
in software development process.
Software quality is an aspect that should be monitored from the initial stages of
the project implementation.

Software quality models
Triangle of quality model is based on three aspects; operation of the product,
continuous revision of the subjected product and transition of the product.
FURPS which discusses characteristics such as functionality, usability,
reliability, performance among other software quality attributes.
Dromey’s Quality Model focuses on evaluating system design, determination
requirements and software implementation phases.

Research methods
Interviews and survey were used to pose some questions to respondents to
determine which software quality metrics are most important
Observation was a significant method of data collection as it involved visiting
software developers and testers while working on some projects.
Experimentation was used in assessing project quality by taking part in project
development and testing.

Research findings
Software quality cannot be attributed to the specific system development phase
but entire process.
All models analyzed advocates adherence to software design principles such as
security, performance, simplicity, functionality and usability.
Models did not factor out change management which affects software quality
processes as well as metrics.

Issues in achieving software metrics
Poor system requirements analysis and specification at in initial phases of
software development.
Unmeasurable system metrics have been a significant challenge in achieving all
desired quality metrics.

Conclusion
Software development fraternity has been facing quality issues due to lack of
proper models to implement required metrics.
It has been very challenging to ascertain if a specific software meets all
requirements.
Change management remains an important aspect that should be considered in
system development like any other project.
The article is relevant to the semester’s courses because it focuses on best
practices which can be used to develop quality and reliable software.
