Final answer:
In Scrum and other Agile methodologies, development is iterative and incremental, often characterized as a spiral design process or continuous development. This approach allows for ongoing adaptation and improvement of the product, mirroring the concept of cumulative development as it iterates through planning, designing, building, testing, and reviewing in repetitive cycles.
Step-by-step explanation:
The Development Practices in Agile Methodologies
The Systems Development Life Cycle (SDLC) typically follows a sequential development process where each phase must be completed before the next one begins. In contrast, the type of development used in Scrum and other Agile methodologies is iterative and incremental, which is often described as a spiral design process or continuous development. Rather than following a rigid sequence, Agile encourages the team to iterate through the design process, incorporating prototyping, testing, and refinement, to evolve the product through successive refinements. This allows for better understanding and continuous improvement of the design, but requires careful management of time and resources to prevent delays and cost overruns.
In Agile methodologies, the development process is viewed as cumulative, adding and improving on features as the project progresses. This is similar to how a child grows physically, adding inches to their height year by year. Agile development cycles include repetitive phases such as planning, designing, building, testing, and reviewing, which are addressed in repetitive cycles, or 'sprints' in the case of Scrum, allowing for ongoing evaluation and adaptation.
The spiral design process in Agile, therefore, offers the advantage of producing a more refined and suitable end product, as the team learns from each iteration and incrementally improves the product. However, as each loop in the spiral requires additional time and resources, it's crucial for Agile teams to effectively manage these aspects to stay within budget and meet deadlines.
