Role and Conference
Scrum has three roles, Product Owner, Scrum Master and Team. You can learn about the roles and responsibilities of participating in Scrum training, and Scrum training is a common way to learn agile development methods. In general, these three roles share the responsibility of the project manager in the classical approach. Team members discuss the project and its results in five periodic meetings of refinement (or arrangement) of product accumulation, sprint planning, daily launch meeting (or daily scrum), sprint review, sprint review meeting.
Scrum courses, classes and tutorials are offered in several organizations, but unfortunately not everything has high quality and precision. In order to verify if the source of information about Scrum is reliable, it is necessary to verify if it has formal scram certification. The Scrum Alliance was the first organization to initiate training and global Scrum certification.
Scrum for Large Companies
Many companies declare a change to agile technology. However, large and medium organizations are often reluctant to change procedures basically. These companies can use the so-called Agile Scale Framework (SAFe) for quick and easy migration. For large developers with multiple teams, another more difficult and fundamental approach is the Grand Scrum (LeSS).
- The agile scale framework team consists of a classic scrum team.
- To provide more valuable software releases, the efforts and results of multiple teams are linked.
- This software is developed taking into account commercial objectives and financial capabilities.
Principles of Agile Scale
- Establish an economic vision
- Think systematically
- Provide variability and leave room for options
- Iterative development with integrated learning cycle in a short period of time
- The degree of achievement is measured through the evaluation of the work system.
- Display and limitation of work in progress, minimization of batch size and tail length
- Use of cadence and cross-domain plan
- Maintain the motivation of developers and designers
- Distribute decision making
Agile Doftware Development History
In 1970, Dr. Winston Royce criticized the traditional development strategy in his thesis "to manage the development of large-scale software systems". He said that the waterfall equates to the conveyor belt for software development and production line, and each part of the final product is added sequentially. The next phase can only be started when the previous phase is completed. Dr. Royce opposed this approach to developing the architecture and the design and programming of the application after the developer first specified all the requirements. He stated that this method is outdated due to the lack of cooperation between the separate teams that work in specific stages.
Waterfall vs. Agile
When comparing the two development methods (waterfalls and agile), it is easy to see why the second project is much more efficient and optimized for a project and is irrelevant for other projects. The main problem with the Waterfall approach is to demand that all the requirements are identified before development begins. In other words, developers and designers must know all the features and details of future programs before proceeding with the actual design and coding. On the other hand, it will be much more convenient if after testing a functional program, the client can provide feedback and judge the functionality. The design agency that adheres to the waterfall approach recognizes that the software built based on the requirements specified a year ago is completely old since the business environment has changed at that time. It is rare Also as a positive example Waterfall is necessary for this project if everything is agreed and the software requirements are clear and concrete.
