METHOD
The initial phase in investigating a subject matter involves the execution of a Systematic Literature Review (SLR).The concept of a literature study is a constituent of SLR, which finds extensive application in information systems research for the purpose of elucidating the current state of knowledge pertaining to a research inquiry.In the context of this SLR, Kitchenham's method is employed, which has garnered widespread adoption across diverse domains, encompassing software engineering, healthcare, and education [7].This methodological approach is characterized by its rigorous and methodically structured framework, facilitating the systematic identification and comprehensive analysis of research studies pertinent to a specific subject.The SLR process is delineated by a well-defined procedure that encompasses several sequential stages, including planning, execution, and the subsequent reporting of the review's findings.(1) Planning stage, the search strategy for finding pertinent studies is devised when the research topic or target is established.As part of the search process, relevant journals and conference proceedings are often manually searched in addition to extensive searches of electronic databases like PubMed or Scopus.Additionally, the inclusion and exclusion criteria are defined, which aid in determining pertinent studies and excluding those that are irrelevant.
(2) Screening stage, based on the inclusion and exclusion criteria, the identified studies are reviewed.Several levels of review are typically performed during the screening process, including title and abstract screening as well as full-text screening.Studies that do not meet the inclusion criteria are excluded from the review, while those that do meet the inclusion criteria are included.
(3) Data extraction stage, the included studies' pertinent data is extracted and synthesised.Typically, this entails gathering data on the study design, sample size, research methodology, and key conclusions.
(4) The reporting stage, the review's findings are synthesised and presented.This usually entails summarising the important findings from the papers presented, noting any gaps in the literature, and offering recommendations for future study.
Kitchenham SLR is a methodical, evidence-based approach that uses a specified methodology for finding and assessing pertinent studies.In order to provide high-quality research findings, it is crucial that the review is thorough, objective, and replicable, which the methodology helps to achieve.The selection process is based on two criteria: inclusion and exclusion.Table 1 provides an explanation of inclusion and exclusion.
Based on the research objectives, inclusion and exclusion criteria from this literature study were created, and they are used to make sure the findings are reliable in accordance with Kitchenham's standards.English-language articles with fulltext papers and a 2018-2023 publication year are available.The structure of the search method is based on the selection of key terms utilizing alternative words and synonyms in each search string (e.g., "AI Engineering").The search for publications took place between 2018 and 2023.The data was obtained from the databases Scopus, ScienceDirect, ACM Digital Library, and IEEE Xplore, and was then integrated into the Mendeley program.Several irrelevant papers were issued at this point based on the title and abstract.There are 400 papers in the literature with details, and 19 of them are included in this research map which is explained by Figure 3.

Various studies highlighting the challenges and methods of developing Artificial Intelligence (AI)-based software.These studies cover a wide range of aspects, from identifying problems in requirements and engineering AI-intensive systems to analyzing ethical requirements and responsible AI [8].Several studies address challenges in requirements engineering for AI, including the precise definition of contextual and data requirements, and the planning and design of efficient AI systems.In addition, it is also important to consider the human factor in the development of AI systems to ensure compliance with the desired goals and ethical values [9].
Other challenges faced are integration of machine learning models in existing infrastructure, testing and validation of AI systems throughout, and deep understanding of user requirements in the intended application domain [10].In the quest to build responsible AI systems, tensions were found in the implementation of ethical requirements, such as a lack of suitable tools and methods to monitor and validate the ethical compliance of AI systems that have been implemented [11].
In addition, challenges were also found in software engineering methodologies that are particularly suitable for developing AI systems, including adapting the SDLC framework with data engineering processes and training models [12].The researchers also present recommendations and frameworks for addressing these challenges, such as TrustOps which offers a risk-based approach to managing trust in AI systems, or an approach that guides users in articulating ethical requirements for explainable AI [13].
Overall, the outcome of these studies is the importance of the discipline of AI Engineering in addressing the challenges of developing AI-based software [14].Using AI techniques and integrating traditional software engineering principles with AI-specific approaches can help create systems that are efficient, responsible and compliant with user requirements and the necessary ethical values.Challenges in AI-based software development are presented in the Table 2:

DISCUSSION
Software engineering is a software development process consisting of various phases and practices that need to be carried out by each stakeholder with the aim that the software built is effective and cost effective.Various software development methods have been proposed, standardized and adopted in the industry.Starting from the most traditional ones such as waterfall which is suitable for use on software whose requirements are clear at the beginning of development [27], to agile which accommodates changes in software requirements, along with the development and operation of the software [28].
The process of developing software development methods adapted to market needs at that time.In the early days of the development of the software industry, the software developed had the aim of optimizing specific business processes in For example, software embedded in aircraft control systems was intended to help pilots control aircraft more easily, reduce human errors and increase aircraft safety factors.Software like this has the characteristics of a clear requirements at the start, and involves limited and specific domain knowledge in the industry.This type of software is expected to have definite requirements at the start, because with its complexity and mission critical nature, changing requirements in the midst of software development will pose a risk not only in terms of cost, but also in terms of the safety of using the software.At that time, the most suitable and commonly used software development method was the waterfall, in which the development process was carried out step by step starting from requirement elicitation to the deployment process.In this method all defined requirements must be traceable to the design, implementation, testing and operational levels.
Along with the advancement of digital technology, the penetration of the use of software has reached homes, and ordinary individuals.With the increased computing capabilities of mobile devices, it is possible for everyone who owns a mobile device to have direct access to the software and become a direct consumer of the software.Software at that time was not only used in offices at work, but had become a tool to support the daily activities of individuals in society.Such as to communicate, directions, places to buy and sell, order food, make payments, etc. Software users are becoming very diverse, and to win the competition, of course, the software manufacturing company must quickly adapt to people's needs and trends in the market.This led to a significant change in the software development process, business and product teams will always come up with new ideas to win over customers.And this must be balanced with the ability to deliver new software features quickly.Driven by such business requirements, the adoption of agile software development is increasing rapidly.
This software development method allows for changes and additions to the software and delivers these requirements quickly.Agile software development is not easily implemented just like that, but is also supported by technology or other tools such as code versioning and collaboration, testing automation, deployment automation which is currently known as continuous integration/continuous delivery (CI/CD).
From the examples of software development events above, every development of a technology will drive new requirements in software development.This need is accompanied by challenges that need to be solved with a new software development paradigm that is supported by technology or tools that can be used in the software development process.
At this time adding artificial intelligence (AI) capabilities to software has become a trend and is implemented in real terms in the industry.Starting from ad recommendations displayed on web services based on web page browsing history to selfdriving cars.
Artificial Intelligence (AI) has the idea of embedding the ability to think, reason and take human action into a machine.Machines are expected not only to be able to perform computations quickly, execute tasks based on predefined instructions and logic, but machines are also expected to be able to learn from input data obtained in their operational processes, and create and derive new rules autonomously.
There are different characteristics between traditional software and software based on Artificial Intelligence.In traditional software, the logic instructions and rules to be executed by the software have been defined from the start, and there will be no changes during the operational process of the software.Rule changes can only be made by changing the software code.This makes traditional software behaviour more predictive.Based on those inputs, one can easily predict the output given by traditional software.
In AI-based software, there are learning capabilities implemented in the software.This makes the behaviour of the software change in line with the operation of the software.These characteristics raise new issues related to the safety of using software that need to be addressed in AI-based software development, such as trustworthiness, explain ability and responsible AI.
In addition, there are additional engineering processes in AI-based software development that are not found in traditional software development.Such as data engineering, data training, model development, and learning monitoring and evaluation after deployment.These complexities present unique challenges that require careful consideration within the software development process.The roadmap analysis of AI engineering methods is instrumental in navigating this evolving landscape and addressing these challenges effectively.

CONCLUSIONS
AI Engineering's transformative role in technology development is unmistakable, as this discipline is set to redefine software and systems development practices.This systematic literature review has been pivotal in uncovering the myriad challenges brought forth by AI integration, with a particular focus on the necessity for clear definitions, contextual requirements, and the establishment of rigorous performance metrics.The complexities of implementing ethical principles within AI software development have been spotlighted, revealing gaps such as inconsistent application and the need for robust validation protocols.These findings emphasize the need for an industry-wide consensus on ethical standards and performance benchmarks, which are critical for the development of AI systems that are not only technologically advanced but also ethically grounded.
The human element within AI Engineering has emerged as a fundamental aspect of this study, underscoring the importance of multi-level governance and process-oriented practices.The introduction of responsible-AI-by-design principles marks a significant stride towards embedding ethical considerations into the fabric of AI systems from the outset.The research has provided frameworks that address the dual challenges of maintaining high performance while ensuring ethical compliance, highlighting the crucial role of human oversight and ethical foresight in AI system development.This embodies a forward-thinking approach that aims to harness AI's capabilities responsibly, ensuring that AI systems serve the broader societal good without compromising ethical values.
In drawing conclusions, this research offers a compendium of insights into the multifaceted challenges encountered in AIbased software development.By outlining the interplay of AI within software development and offering strategic avenues, it paves the way for stakeholders to effectively navigate these intricacies.
The study's comprehensive set of recommendations and pragmatic approaches is a testament to the ongoing endeavor to realize AI's full potential responsibly.Future research directions are poised to refine these strategies further, ensuring that as AI continues to evolve, it does so with an unwavering commitment to ethical standards, user-centric design, and an inclusive vision for technology's role in society.
