As technology continues to advance rapidly, the field of software engineering is constantly evolving to meet new challenges and opportunities. Emerging software engineering trends represent the forefront of innovation, shaping the way software is developed, deployed, and utilized. Some of the key emerging trendsin Background Software engineering is a crucial field that addresses the design, development, testing, deployment, and maintenance of software systems. It emerged as a response to the growing complexity of software applications and the need for systematic approaches to building and managing large-scale software projects. The background and significance of software engineering can be understood by the growing software complexity and crisis [2]. In the 1960’s, computer scientists and software developers began to face what was known as the "software crisis." This crisis was characterized by the inability to meet project deadlines, budget overruns, and a high rate of software project failures. The need for a systematic, engineering-based approach to software development was recognized [3].

Agile software development methodologies
Agile methodologies are a set of principles and practices designed to promote flexibility, collaboration, and adaptability in software development and project management.
The agile approach contrasts with traditional, linear project management methods (like the waterfall model) that follow a sequential and rigid process. Instead, agile methodologies emphasize iterative development, frequent feedback, and continuous improvement. Some popular agile methodologies include the following [4]:
Extreme Programming (XP): XP emphasizes technical practices to ensure high-quality software, such as Test-Driven Development (TDD), continuous integration, pair programming, and frequent releases. It aims to deliver valuable software quickly while maintaining a high level of quality.
Lean software development: Inspired by Lean manufacturing principles, software development focuses on minimizing waste, maximizing value, and optimizing the whole development process. It encourages early and frequent deliveries, empowering teams to adapt to changes rapidly.
Scrum: Scrum is a widely-used agile framework that organizes work into fixed-length iterations called "sprints," usually lasting two to four weeks. It employs a set of predefined roles (Scrum master, product owner, and development team) and ceremonies (Daily standups, sprint planning, sprint review, and sprint retrospective) to facilitate collaboration and incremental development.
Kanban: Kanban is based on the visualization of work items on a Kanban board, allowing teams to manage their workflow more efficiently. It promotes a continuous flow of work, with tasks moving from "To Do" to "In Progress" to "Done" columns, focusing on limiting work in progress and promoting a steady delivery pace.
We should note that, the adoption of agile methodologies has led to benefits, including improved customer satisfaction, reduced project risks, better adaptability to changing requirements, and increased collaboration within development teams. However, it also requires commitment and active participation from all team members and stakeholders to be truly effective.
Evolution of agile methodologies
The evolution of agile methodologies is a fascinating journey that reflects the software development industry's continuous search for better ways to deliver high-quality products efficiently. The agile movement originated in the 1990’s, and over time, it has evolved and diversified into various methodologies and frameworks. Here's a brief overview of the key milestones in the evolution of agile methodologies:
Incremental and iterative development (1970’s-1980’s): The roots of agile can be traced back to the incremental and iterative development practices introduced in the 1970’s and 1980’s. Early software developers began to realize the benefits of breaking large projects into smaller, manageable increments and iterating on them to improve the product continuously.
Adaptive Software Development (ASD) and crystal (1990’s): In the early 1990’s, Jim Highsmith developed adaptive software development, which emphasized collaboration, incremental development, and embracing change. Around the same time, Alistair Cockburn introduced crystal methodologies, which focused on tailoring the development process based on the project's unique characteristics and team size.
Scrum (Mid 1990’s): Scrum, one of the most popular agile frameworks, was formalized in the mid 1990’s by Jeff Sutherland and Ken Schwaber. It draws inspiration from Lean manufacturing and emphasizes short, time-boxed iterations (sprints), cross-functional teams, and frequent inspection and adaptation through ceremonies like daily standups, sprint planning, and retrospectives.
Extreme Programming (XP) (Late 1990’s): XP, developed by Kent Beck and others, emerged in the late 1990’s. It promoted engineering practices such as Test-Driven Development (TDD), pair programming, continuous integration, and small, frequent releases. XP aimed to deliver high-quality software in a flexible and customer centric manner.
Agile manifesto (2001): The term "Agile" gained prominence in 2001 when seventeen software development practitioners, including representatives from Scrum, XP, ASD, and other approaches, met to define the core values and principles of agile software development. This resulted in the agile manifesto, which laid the foundation for the agile movement.
Agile methodologies proliferation (2000’s): Throughout the 2000’s, various agile methodologies and frameworks gained popularity, such as Feature-Driven Development (FDD), Dynamic Systems Development Method (DSDM), and Kanban. Each methodology offered its unique approach to agile software development, catering to diverse project requirements.
Scaling agile (2010’s): As agile adoption spread to larger organizations and complex projects, the need for scaling agile methodologies arose. Frameworks like Scaled Agile Framework (SAFe), Large-Scale Scrum (LeSS), and Disciplined Agile Delivery (DAD) were developed to address the challenges of scaling agile practices across multiple teams and departments.
Modern trends and customization (Present): In recent years, agile has continued to evolve and adapt to changing industry needs and technological advancements. Trends like DevOps, Continuous Integration/Continuous Deployment (CI/CD), and Lean agile have further influenced agile methodologies' evolution, promoting continuous delivery and increased collaboration between development and operations teams.

Agile remains a dominant force in modern software development, and its principles continue to shape how teams approach projects and respond to ever-changing business needs.
Agile manifesto and principles
The agile manifesto, created in 2001 by a group of seventeen software development practitioners, is a foundational document that defines the core values and principles of agile software development. It emphasizes a flexible and customer-centric approach to delivering software, focusing on collaboration, adaptability, and delivering value [5].
Below are the four (4) key values of the agile manifesto that software developers used to guide their development tasks.
Agile manifesto values
• Individuals and interactions over processes and tools: Agile values the importance of people working together effectively over relying solely on rigid processes or tools. Good communication and collaboration are essential to the success of agile teams.
• Working software over comprehensive documentation: While documentation has its place, agile prioritizes delivering functional software that provides value to customers. Working software is the primary measure of progress.
• Customer collaboration over contract negotiation: Agile fosters close collaboration with customers and stakeholders throughout the development process. Customer feedback is actively sought and used to ensure the delivered software meets their needs.
• Responding to change over following a plan: Agile recognizes that requirements and priorities can change during a project’s course. Instead of rigidly adhering to initial plans, agile teams embrace change and adapt their approach to maximize value.
Similarly, the twelve (12) principles outlined in the agile manifesto:
Agile manifesto principles
• Satisfy the customer through early and continuous delivery of valuable software: Agile teams aim to deliver functional software in short iterations, providing customers with valuable features early and frequently. Early delivery of deliverables does not mean quality is compromised.
• Welcoming changing requirements, even late in development: Agile projects expect and accommodate changes in requirements, embracing them as opportunities to improve the software’s fit with customer needs. Customer sophistication in terms of requirement changes is one of the main reasons why agility was given birth to. To deny customers of requirement changes in the course of the development and delivery process is like going back to the traditional methods of software development, and not agile methodology.
• Deliver working software frequently, with a preference for shorter timescales: Frequent delivery of working software allows for faster feedback and enables teams to adjust their approach based on real-world results.
• Collaborate daily between business people and developers throughout the project: Regular collaboration between the business side and development teams ensures a shared understanding of project goals and requirements.
• Build projects around motivated individuals, giving them the support and trust they need to get the job done: Empowered and motivated individuals are more likely to produce high-quality results. Agile teams trust their members to make decisions and value their expertise.
• Use face-to-face communication whenever possible: Face to-face communication is highly valued in sgile, as it tends to foster better understanding, improve collaboration, and build stronger relationships between team members.
• Working software is the primary measure of progress: Rather than relying on comprehensive documentation or completed tasks, agile measures progress based on the delivery of functional, tested software.
• Maintain a sustainable pace of work for the development team: Agile teams avoid burnout and maintain productivity by working at a sustainable pace over the long term. Agility requires constant pace so that projects can be delivered within the shortest possible time. This is key, and without it, there is nothing like agility. • Continuous attention to technical excellence and good design enhances agility: Technical practices such as refactoring, automated testing, and continuous integration are essential to maintaining code quality and enabling rapid responses to change.
• Simplicity–the art of maximizing the amount of work not done is essential: Agile teams aim to minimize unnecessary work and complexity, focusing on delivering the most valuable features.
• Self-organizing teams make the best architectures, requirements, and designs emerge: Empowered teams that collaborate effectively often produce better solutions than those dictated by external authorities.
• At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly: Agile teams engage in regular retrospectives to review their processes, identify areas for improvement, and make the necessary adjustments to enhance their performance.
These four (4) values and twelve (12) principles serve as the guiding philosophy for agile methodologies and encourage teams to embrace flexibility, adaptability, and continuous improvement in their software development processes.
