Agile software development emphasizes flexibility, collaboration, and iterative progress, integrating customer feedback, adaptive planning, self-organizing teams, and continuous improvement practices through the following key principles:
1. Customer Collaboration: Continuous feedback ensures products evolve to meet customer needs, enhancing satisfaction and relevance.
2. Iterative Development: Projects are structured into sprints (1-4 weeks), facilitating regular reviews, adjustments, and incremental software delivery. This enables teams to swiftly adapt to changes and consistently deliver value.
3. Adaptive Planning: Plans respond dynamically to feedback and prioritize high-value features, optimizing resource allocation aligned with business goals.
4. Self-Organizing Teams: Empowered teams decide how to achieve goals, fostering creativity, ownership, and accountability for innovative solutions and heightened productivity.
5. Continuous Improvement: Sprint retrospectives refine processes, enhancing efficiency, quality, and team cohesion over time.
These principles promote transparency, adaptability, and responsiveness in project management and product delivery. Agile methodologies enable rapid value delivery, mitigate risks through early testing, and maintain alignment with customer needs throughout development. By emphasizing collaboration, iterative development, and ongoing improvement, Agile practices facilitate the delivery of high-quality products that meet customer expectations and adapt effectively to changing market demands, securing sustained competitive advantage in dynamic business environments.

First Come First Serve
First Come First Serve is the full form of FCFS. It is the easiest and most simple CPU scheduling algorithm. In this type of algorithm, the process which requests the CPU gets the CPU allocation first. This scheduling method can be managed with a FIFO queue.
Shortest Remaining Time
The full form of SRT is Shortest remaining time. It is also known as SJF preemptive scheduling. In this method, the process will be allocated to the task, which is closest to its completion. This method prevents a newer ready state process from holding the completion of an older process.
Priority Based Scheduling
priority scheduling is a method of scheduling processes based on priority. In this method, the scheduler selects the tasks to work as per the priority.
Priority scheduling also helps OS to involve priority assignments. The processes with higher priority should be carried out first, whereas jobs with equal priorities are carried out on a round-robin or FCFS basis. Priority can be decided based on memory requirements, time requirements, etc.
As the process enters the ready queue, its PCB (Process Control Block) is linked with the tail of the queue. So, when CPU becomes free, it should be assigned to the process at the beginning of the queue.
Round-Robin Scheduling
Round robin is the oldest, simplest scheduling algorithm. The name of this algorithm comes from the round-robin principle, where each person gets an equal share of something in turn. It is mostly used for scheduling algorithms in multitasking. This algorithm method helps for starvation free execution of processes.
Shortest Job First
SJF is a full form of (Shortest job first) is a scheduling algorithm in which the process with the shortest execution time should be selected for execution next. This scheduling method can be preemptive or non-preemptive. It significantly reduces the average waiting time for other processes awaiting execution.
