\section*{Introduction}

{\label{introduction}}

Today, a lot of businesses rely on software to manage their daily
operations, therefore software development has turned into a necessity.
The importance of software quality is growing since it directly
influences how well it performs the tasks for which it was designed.
Software quality is determined by several factors, including software
maintenance practices, and refers to how effectively a piece of software
meets the needs and expectations of its users.

The process of changing and updating the software after it has been
launched is known as software maintenance, and it is a crucial step in
the software development life cycle. For software to continue to be
successful and practical over time, this is crucial. Bug patches,
changes in user needs, technological advancements, and other reasons all
contribute to the need for software maintenance.

Despite the significance of software maintenance, prior research has
mostly concentrated on evaluating the expertise of the maintenance team,
the software development technique employed, and the kind of software
being maintained. There has been a glaring void in the literature when
it comes to examining the connection between software maintenance
procedures and software quality.

This study will look at how software maintenance affects software
quality to close this gap. There are four main methods of software
maintenance that can guarantee the most noteworthy level of software
quality. They are,

\begin{enumerate}
\tightlist
\item
  Corrective Maintenance
\item
  Adaptive maintenance
\item
  Perfective Maintenance
\item
  Preventive Maintenance
\end{enumerate}

Corrective maintenance points to settle defects, errors, and bugs within
the program that have been identified by clients or through testing.
Corrective maintenance ensures that the software package is free of
issues and works as aimed. Adaptive maintenance includes altering the
computer program to oblige changes within the environment in which it
works. For illustration, changes in equipment, working frameworks, or
lawful necessities may require alterations to the software package.
Adaptive maintenance guarantees that the software is up-to-date and
compatible with its environment. Perfective maintenance points to move
forward the quality of the package by improving its usefulness or
execution. It includes adjusting the software to include modern
highlights or progress existing ones, to enhance user satisfaction and
expand efficiency. Preventive Maintenance includes taking proactive
measures to avoid issues from happening within the package. This may
incorporate standard framework reinforcements, execution observing, and
security overhauls. Preventive maintenance guarantees that the program
framework is solid, steady, and secure.

The purpose of the study is to discover how different software
maintenance techniques affect software quality. It specifically seeks to
ascertain whether there is a substantial relationship between the
frequency of maintenance tasks and the caliber of the software. The
study also attempts to investigate how various maintenance practices,
such as corrective, adaptive, and perfective maintenance, affect
software quality.

Software maintenance is essential for ensuring software quality, yet
little is known about how maintenance procedures affect program quality.
Despite the significance of software maintenance, there is a lack of
knowledge regarding the difficulties, ideal procedures, and trade-offs
involved. As a result, research is required to determine how software
maintenance contributes to software quality assurance and to propose
efficient management solutions for software maintenance that would
maximize software quality. To increase software quality, this research
intends to examine the connection between software maintenance and
quality and to pinpoint the best strategies for handling software
maintenance.

This study has significance because it can assist teams working on
software development in identifying and putting into practice
maintenance strategies that will ultimately result in software of higher
caliber. We can better comprehend the elements that go into creating
high-quality software and devise tactics to streamline the maintenance
procedure by looking at the role that maintenance plays in software
quality. Both theoretical and practical ramifications for the larger
software engineering community as well as practical ramifications for
software development firms may result from this research.

This study has the following precise goals:

\begin{itemize}
\tightlist
\item
  Examine the connection between software quality and maintenance
  procedures.
\item
  Determine the best software maintenance procedures for preserving
  software quality.
\item
  Examine the effect of software maintenance on the price and duration
  of software development.
\end{itemize}

The following are the study's hypotheses:

Good software maintenance procedures have a favorable effect on software
quality.

Time and money spent on software development are cut down due to
efficient maintenance procedures which in turn affect software quality.

The following research queries will be addressed in this study:

\begin{itemize}
\tightlist
\item
  Which methods of software maintenance ensure the highest level of
  software quality?
\item
  How do software maintenance costs and schedules affect software
  development so that it will affect the software quality?
\item
  What connection exists between software maintenance procedures and
  software quality?
\end{itemize}

Before beginning this research study, a thorough review of the body of
knowledge on software maintenance practices and software quality will be
conducted. The publication will go into great depth about the research
design, data collection techniques, participant selection, and data
analysis procedures. In the paper, the results of the data analysis will
be given together with a discussion on how they could influence the
practices used in software development. Following a discussion of the
study's flaws, the report will offer suggestions for additional
research.

\section*{literature review}

{\label{literature-review}}

Software maintenance is an ongoing process that takes place after
software development is completed. Its goal is to keep the software
functioning as expected and in line with users' evolving needs. The
importance of software maintenance is often underestimated, and it is
often not given the attention it deserves. Software maintenance accounts
for more than 50\% of the overall cost of software development,
according to Lehman and Belady (1985). This demonstrates how crucial
software maintenance is to maintaining software quality. In this
literature review, we will examine the role of software maintenance in
ensuring software quality.

\subsection*{Software Maintentance
Procedures}

{\label{software-maintentance-procedures}}

The case study conducted by Hassan and Holt(2003) in order to test the
connection between software quality and software maintenance of a large
software system in a financial institution was done by gathering both
subjective and objective software quality measures. They then analyzed
software system maintenance data for two years to establish the
association between software quality and software maintenance. The study
includes 23 empirical investigations that used various software quality
measures, such as defect density, reliability, maintainability, and
customer satisfaction .

Similarly, T. Mens and S. Demeyer (2008), proposed a reuse-based
strategy to software maintenance and evolution instead of making random
modifications to the code, they advised identifying common
functionalities and developing reusable components that could be used to
modify the source. This method entails identifying and abstracting
common functionality in the software system, as well as developing
reusable software components. It underlines the significance of reusing
code in maintenance because it can save the time and effort necessary
for bug repair and testing. A huge Java-based software system utilized
by a Belgian bank was the subject of the case study. In the codebase,
authors recognized specific common functionalities and constructed
reusable components to implement these functionalities.

\subsection*{Software Maintenance Costs And
Schedules}

{\label{software-maintenance-costs-and-schedules}}

It is crucial to balance the need for maintenance with the need for new
development to ensure that software remains stable and up-to-date while
meeting the changing needs of its users.

Development cost: Software maintenance expenses can have an impact on a
project's development expenditures. The ability of the development team
to allocate resources to the development of new functions or other
projects may be impacted if the maintenance expenses are significant.
This can cause software development to take longer and cost more money
to complete. As depicted by Fig. 1, the cost of fixing bugs~in a typical
software development cycle. The cost of fixing bugs in the maintenance
stage looks to be substantially higher than the cost of fixing issues in
all other stages combined, as seen in the figure. As a result, proper
software development requires solid design and ensuring that the
software is extensively evaluated to remove problems as much as possible
before the product is given to the market or customers so that the costs
of maintaining the software are reduced.

Schedule: The software maintenance schedule can have an impact on
software development and software quality. Overly frequent maintenance
may cause development delays or possibly program instability. On the
other side, if maintenance is performed infrequently, bugs and other
issues may build up, increasing the probability of software failure.

Izquierdo-Cortazar et al. (2011) investigated the effect of corrective
maintenance on software development. The process of finding, analyzing,
and repairing problems or faults in software programs is referred to as
corrective maintenance. It emphasized the importance of early detection
and rectification of issues in order to keep the project on schedule.
Bugs that are discovered early can be corrected before they cause major
delays. On the other side, if defects go unnoticed for an extended
period of time, they might pose substantial issues that cause
significant delays in the project schedule. The researchers employed a
case study approach to perform the study and analyzed data from a
software development project that required corrective maintenance. They
analyzed project data and ran computer simulations to examine the
influence of various corrective maintenance procedures on schedules for
the project .

Similarly, Edward E. Ogheneovo(2016) explored the relationship between
software complexity and maintenance costs. Specifically, the study aims
to investigate whether there is a positive relationship between software
complexity and maintenance costs, and to identify the factors that
contribute to this relationship. The study focuses on software systems
developed using the Object-Oriented Programming (OOP) paradigm, which is
widely used in modern software development.

Ogheneovo conducted the study by analyzing data from five software
systems built by a single organization. He measured the complexity of
software systems using many software complexity metrics, such as the
number of classes, the number of methods, and the depth of inheritance.
He also gathered information on the maintenance costs for each software
system, such as the number of repair requests and the time and effort
required to complete each one. The research emphasizes the significance
of smart software design in reducing software complexity and lowering
maintenance costs. Modularization and encapsulation are two design
principles that software development organizations can use to reduce
reliance among software components and simplify program development and
maintenance .

The authors define software complexity as the difficulty of
understanding and modifying a software system. They claim that
complicated software is more expensive to maintain since it demands more
effort and time to comprehend, modify, and test. The authors studied a
sample of COBOL programs from three distinct organizations. To assess
the program's complexity, they utilized a statistic known as cyclomatic
complexity. They also gathered information on the program's maintenance
expenditures, such as the time spent on maintenance, the number of lines
of code updated, and the number of errors made during maintenance.
Figure 2 depicts the costs of fixing bugs in a typical software life
cycle. The cost of fixing bugs in the maintenance stage looks to be
substantially higher than the cost of fixing issues in all other stages
combined, as seen in the figure. As a result, there is a need to
properly build software by having solid design and ensuring that the
software is fully tested to remove flaws as much as possible before the
product is published to the market or customers in order to lower the
expenses of maintaining the software.

\section*{Methodology}

{\label{methodology}}

In this study, it has reviewed the literature to examine the
relationship between software maintenance practices and software quality
as well as the effects of software maintenance expenditures and
timelines on software development. It has looked through a variety of
sources, including online databases like IEEE Xplore, ResearchGate, and
Google Scholar, to find pertinent research papers, books, and conference
proceedings on software maintenance and software quality. To focus the
search, it has added terms like software development, software quality,
and maintenance costs. Following a preliminary inspection of the search
results, the chosen papers are further assessed considering their
relevance to our study goals. Studies that were authored in English and
released between 1990 and 2021 were selected. Studies unrelated to
software maintenance and software quality or not pertinent to the study
goals were excluded.

Moreover, the chosen papers are analyzed to determine major themes and
conclusions about software maintenance practices, software quality, and
the effect of software maintenance budgets and schedules on software
development. To synthesize the data from the chosen studies and make
judgments regarding the study issues, a qualitative methodology is
adopted. To approve the viability of the investigation results, a few
case studies are investigated and examined included within the chosen to
inquire about articles. This case is used considers demonstrating the
key themes and discoveries of our investigation and to supply real-world
illustrations of software support methods and their effect on its
quality and development.\selectlanguage{english}

One
of the approaches used in this study was to conduct a survey to gather
information from experts in the field of software engineering about
their experience with software maintenance best practices to Ensure
software quality at the highest level. The survey was conducted online,
and participants were recruited through professional networks and social
media platforms as shown in Fig. 2. Survey data was collected and
analyzed using statistical software to identify trends and patterns in
the responses. The survey results are
then
used to draw conclusions about the most effective software maintenance
methods to ensure software quality. This survey was conducted with the
aim of collecting valid and reliable data from experts in the field of
software engineering to provide insight into the role of software
maintenance in ensuring quality.

quality and development.

\section*{Results}

{\label{results}}

The study assessed how various software maintenance techniques, such as
bug patching and code refactoring, affect the caliber of the software.
The study intends to shed light on efficient software maintenance
techniques that can be applied to improve software quality as depicted
in Fig. 3.

In order to evaluate the hypothesis that good software maintenance
methods improve software quality, Hassan and Holt conducted a study in
2003. Using data from twelve large software systems, the study
investigated the impact of software maintenance on software quality. The
strength of this relationship was discovered to vary depending on the
precise quality measure utilized in each investigation. Those whose
studies utilized fault density as a quality indicator, for example,
found a stronger association between maintenance and quality than those
that used other measures. Higher levels

of software quality were shown to be connected with lower maintenance
costs and fewer faults, as well as increased maintainability and
customer satisfaction, according to the study .

In the second study, Mens, and S. Demeyer (2008) discovered that the
reuse-based approach was effective in reducing maintenance effort and
time to resolution while also improving software quality, which examined
the impact of software maintenance on software quality using data from
ten open-source software systems .

The approach specifically enables developers to reuse existing software
artifacts and components, reducing the amount of time and effort
required to create new ones from scratch. Furthermore, the reuse-based
strategy helped in the improvement of software quality by encouraging
the usage of proven, tested components that had previously been utilized
in other parts of the software system. Furthermore, the authors stated
that the reuse-based strategy was well-received by the developers,
showing that it was viewed as an effective and efficient way to manage
maintenance and evolution responsibilities.\selectlanguage{english}
\begin{figure}[H]
\begin{center}
\includegraphics[width=0.70\columnwidth]{figures/image7/image7}

\end{center}
\end{figure}

The second study topic investigates the financial and time implications
of software maintenance on software development. Fig. 4, shows how the
cost is distributed in the SDLC. The purpose of this was to find out how
the total software development process is impacted by software
maintenance costs and timelines.

Correcting, modifying, enhancing, and perfecting an already-in-use piece
of software are all included in software maintenance. The user has the
choice of whether to rectify, modify, enhance, or perfect the software,
excepting major faults and necessary adjustments. The upkeep task is not
necessary. It is frequently possible to continue using the software in
its current state, even in cases of non-critical problems. Time and
money are the two factors that determine whether to complete the
maintenance operation or not. When improvements and perfection are
involved, time and money are even more crucial factors. Considering the
current economic climate, everything comes down to weighing the costs,
benefits, and priorities.

Regarding the hypothesis that efficient maintenance procedures reduce
time and money spent on software development, which in turn affects
software quality, Edward E. Ogheneovo (2016) discovered a positive
relationship between software complexity and maintenance costs.
Ogheneovo discovered that as the complexity of the software system
grows, so does the number of maintenance requests and the time and work
necessary to accomplish each request. The study also discovered numerous
elements that influence this relationship, such as the size and
complexity of the program code, the number of features and
functionalities, and the degree of interdependence among software
components . In addition, Rajiv D. Banker et al. (1990) found that
programs with higher cyclomatic complexity ratings were associated with
higher maintenance costs. They also discovered that programs with
greater maintenance expenses have a higher rate of error during
maintenance. The authors examine the significance of their findings for
software development and maintenance, arguing that developers should
work to reduce software complexity in order to reduce maintenance costs
.

With regards to address one of the research queries regarding the best
methods of software maintenance that ensures the highest level of
software quality, a survey was conducted. The aim of the survey was to
gather information from the professionals' opinions and experiences
based on their experience with projects with regard to software
maintenance techniques. Almost half of those polled (47.6\%) have
previously worked on a software maintenance project, demonstrating that
software maintenance is a popular activity in the software business.\selectlanguage{english}
\begin{figure}[H]
\begin{center}
\includegraphics[width=0.70\columnwidth]{figures/image9/image9}

\end{center}
\end{figure}

Corrective maintenance (33.3\%), preventive maintenance (28.6\%), and
adaptive maintenance (28.6\%) were chosen as the most effective methods
of software maintenance by participants {[}Fig. 7{]}. The majority of
participants (76.2\%) cited problems with software quality owing to a
lack of effective maintenance and this is depicted by Fig. 5,
emphasizing the necessity of regular maintenance in preventing problems
in the first place. The panelists divided the most essential components
in guaranteeing software quality as regular maintenance (28.6\%) and
testing (33.6\%) {[}Fig.6{]}. Corrective maintenance was judged to be
the most time-consuming (42.9\%) of software maintenance strategies
{[}Fig. 9{]}. In terms of cost-effectiveness, adaptive maintenance
(33.6\%) was considered to be the most cost-effective, followed by
preventative maintenance (28.6\%) {[}Fig. 8{]}.\selectlanguage{english}
\begin{figure}[H]
\begin{center}
\includegraphics[width=0.70\columnwidth]{figures/image11/image11}

\end{center}
\end{figure}

Overall, the survey findings highlight the importance of software
maintenance in guaranteeing software quality and suggest that a variety
of strategies may be required to achieve this aim.

\section*{Discussion}

{\label{discussion}}\selectlanguage{english}
\begin{figure}[H]
\begin{center}
\includegraphics[width=0.70\columnwidth]{figures/image12/image12}

\end{center}
\end{figure}

The
research findings demonstrated how crucial software maintenance is for
maintaining the effectiveness, dependability, and quality of software
systems. The research, in particular, shows that effective software
maintenance practices can enhance software quality, save maintenance
costs, and raise customer happiness. The research also emphasized some
of the major difficulties in managing dependencies, ensuring security,
maintaining performance, and controlling costs in relation to software
maintenance.\selectlanguage{english}

\end{figure}

A significant finding from the secondary research studies was that
software complexity and maintenance costs have a positive correlation.
This argues that software developers should work to simplify their
products in order to cut maintenance expenses and raise software
quality. By using this approach, developers can reuse pre-existing
software artifacts and components, saving time and effort compared to
creating new ones from scratch. Customer that increased software quality
was linked to cheaper maintenance costs, fewer faults, improved
maintainability, and higher customer satisfaction was another
significant discovery. This emphasizes the value of spending money on
software maintenance to keep software systems dependable and effective
over time. Developers should carefully examine the measurements to
employ when analyzing Developers should carefully examine the
measurements to employ when analyzing the influence of maintenance on
software quality, according to the studies, which also revealed that
different measures of software quality may have differing levels of
association with maintenance.

With regards to the survey conducted in order to collect primary data,
the analysis showed corrective, preventive, and adaptive maintenance as
the most effective hence implying that, depending on the scenario,
multiple forms of maintenance are required, and that a variety of
approaches may be required to assure software quality. In addition to
this, regular maintenance and testing were considered extremely critical
to guaranteeing software quality since regular maintenance may prevent
problems from happening and testing can discover problems that need to
be fixed.

Adaptive maintenance followed by preventative maintenance being the most
cost-effective maintenance techniques suggests that making modifications
or upgrades to the software to adapt to changes in the environment or
avoid future issues may be more cost-effective in the long term than
repairing problems after they arise. To elaborate more on this,
preventive maintenance is making alterations or updates to the program
to maintain a strategic distance from future faults or issues.
Developers can avoid expensive and time-consuming challenges afterward
within the software development process by proactively tending to be
planned concerns. This has influence to ensure that the program fits the
requirements and details and that it runs easily and without mistakes.
Preventive maintenance moreover ensures that the program is up to date
and able of adjusting to changes within the working framework or
equipment.to adjust to changes within the working framework or
equipment. Adaptive maintenance, on the other hand, involves upgrading
the program to suit changes within the environment, such as working
frameworks or equipment adjustments. This can be noteworthy since, as
the technological landscape advances, software must adjust to stay
pertinent and effective. Software may remain useable, utilitarian, and
high performing by responding to changes within the environment.
Adjusting computer programs to fit unused necessities or guidelines is
another case of adaptive maintenance.

Preventive and adaptive maintenance must work in pairs to guarantee
software quality. They help with the anticipation of issues and ensure
that the program proceeds to perform legitimately in changing settings.
Without this sort of support, the program can before long end up old and
out of date, coming about resulting in expanded costs, lower
effectiveness, and decreased execution. Besides, by diminishing the
prerequisite for remedial support, both shapes of maintenance can serve
to lower the fetch of software advancement. Designers can avoid more
exorbitant and time-consuming corrective maintenance endeavors down the
line by tending to conceivable issues early on. This will inevitably
assist in lower add up to software development costs and increase the
program's return on the venture. Increase the program's return on the
venture. Finally, preventative and adaptive maintenance is basic for
moving forward program quality. They contribute to the software's
long-term ease of use, usefulness, and execution, indeed when the
environment and requirements change. Designers may construct a program
that is more steady, efficient, and cost-effective in the long term by
prioritizing certain shapes of support.

Overall, the findings of the survey and research studies indicate that
software maintenance is an important activity for ensuring the quality
and reliability of software systems throughout time. Regular maintenance
and testing are critical, and businesses may wish to consider spending
more on preventive and adaptive maintenance in the future to lessen the
need for corrective maintenance. To ensure that software systems stay
dependable and performant over time, developers should seek to reduce
program complexity, employ efficient maintenance techniques, and invest
in continuous maintenance activities.

\subsection*{Limitations and Further
Research}

{\label{limitations-and-further-research}}

One restriction of the research studies presented in the literature
review is that they may not be applicable to all types of software
systems. The research mostly focused on large, complicated software
systems and open-source software, which may not be representative of
other software development situations. Furthermore, the questionnaire
survey may have a sample bias because the sample of participants
included undergraduate students who may not be representative of the
population being studied because they are still unclear about the topic
addressed, resulting in limited generalizability of the results.
Response bias may also exist, in which participants may not respond
accurately or choose the answer they believe the researcher wants to
hear, resulting in erroneous results.

Researchers in the future could build on prior studies' limitations by
investigating software maintenance strategies and their impact on
software quality in a larger range of software development situations.
Smaller and less sophisticated software systems, proprietary software,
and a broader range of quality criteria could all fall under this
category. Future study could also look into new and innovative software
maintenance approaches that could improve software quality while
reducing maintenance costs and time. Subsequently, it might look into
the impact of upcoming technologies like artificial intelligence and
machine learning on software maintenance and how they relate to software
quality.

\section*{conclusion}

{\label{conclusion}}

Software maintenance is critical to guaranteeing the software quality
throughout the program's lifetime. Maintenance efforts, which entail
altering, repairing, or improving software systems to meet changing
needs, address defects, and improve performance, can have a direct
influence on software quality. Effective maintenance techniques keep
technical debt at bay and guarantee that software systems continue to
provide value overall.

Software maintenance costs and schedules can have a significant impact
on software quality. Poorly managed maintenance activities can lead to
delays, cost overruns, and substandard results. If not planned and
executed properly, maintenance activities can introduce new bugs, create
new dependencies, and have unpredictable results. This can lead to
lower-quality software as systems become more complex, more difficult to
maintain, and less stable.

Effective maintenance methods, on the other hand, may improve software
quality by ensuring that software systems stay dependable, efficient,
and up to date. Regular maintenance efforts like code reviews, testing,
and refactoring can assist in detecting bugs early and preventing them
from becoming severe issues. Furthermore, maintenance actions focused on
enhancing software architecture and design can assist decrease technical
debt and enhance system modularity, making the system easier to
maintain, adapt, and scale over time. Software quality is intimately
tied to software maintenance processes. Maintenance work assists in
identifying parts of the software that require improvement and in
keeping the program operational at all times. Maintenance methods are
also critical to ensuring that software systems can adapt to changing
user and stakeholder demands. Maintenance teams can discover foreseeable
problems and prioritize bug fixes that enhance software quality by
monitoring system performance and offering feedback.

Maintenance efforts must be carefully planned and conducted to achieve
the greatest level of software quality. Maintenance teams should
prioritize actions that have the greatest impact on software quality
using data-driven techniques. They should also make maintenance efforts
as visible and predictable as possible so that stakeholders understand
what is going on and how it impacts them. Maintenance teams may develop
confidence and ensure stakeholders remain engaged and involved in the
software over time by incorporating stakeholders in maintenance
activities and giving them timely information about changes to the
program.

In conclusion, software maintenance is an important aspect of
guaranteeing long-term software quality. Effective maintenance methods
may help to avoid technological debt, spot problems early, and maintain
software systems dependable, efficient, and up to date. Maintenance
tasks that are poorly managed can impair software quality and make
software systems difficult to maintain, alter, and scale. As a result,
maintenance teams must carefully plan and execute maintenance tasks,
prioritize activities using data, and include stakeholders to maintain
transparency and involvement. Organizations may maintain high-quality
software systems and offer value over time by adhering to software
maintenance best practices. Effective maintenance methods may help to
