It was in 1970 that the American computer scientist Winston Royce compiled a document called "Managing the development of large software systems."
Instead of waiting for all the stages (phases) to be completed in sequence, Royce suggested using a phased approach. The essence of it is that initially, all the requirements necessary for the project are collected, after which the entire architecture is completed, the design is created, the code is written, etc.
Based on this, in the '90s, we managed to create a set of flexible software development methods that can replace complex and time-consuming methods.
Application of waterfall and agile methodologies
The Agile methodology is primarily based on visual control. Most often, project participants use special color cards when working on achieving results by means of a waterfall and agile methodologies.
In most cases, team members and the client in agile/scrum methodologies work together and side by side. Agile has the following principles:
- to provide a direct interaction between developers (the possibility of direct contact contributes to a more successful communication);
- to measure progress only through working software (clients should only receive functional and working software);
- to maintain a continuous pace of work (the team must develop an optimal and supported speed of work);
- to pay attention to design and technical details (thanks to effective skills and good design, the project team gets an opportunity to improve the product and work on its improvement constantly);
- to try to make the workflow as simple as possible, in a simple and understandable way.
Another important aspect of the Agile methodology is the division of the entire project volume into several smaller components. This approach greatly simplifies the development process, and individual groups of teams can focus on their own specific task.
Different types of agile methodologies
Scrum type significantly increases productivity and reduces time compared to classic waterfall processes. By practicing Scrum processes, organizations can smoothly adapt to changing requirements, and they can create a product that meets dynamic business goals.
A Kanban process aims to help you organize teamwork more effective while using agile development methodologies. Kanban is designed to ensure maximum transparency of the development process and evenly distribute the load between all team members. Kanban encourages the strengthening of cooperation, a desire to develop, improve knowledge and skills actively.
Thus, we can conclude that Agile methodology is extremely important to the successful work of Global software development teams.
