Agile Software Development: Professional Approach and its Main Principles

Agile is a software development methodology aimed at improving traditional processes. This modern approach is extremely flexible because developers can respond quickly to changing requirements thanks to close cooperation, feedback and repeated development cycles. The Agile development process is an alternative approach that generally counteracts the classic Waterfall method and software development life cycle methodology. In case you are not familiar with Internet technology or want more information about various development methods, this article presents two main approaches to software design and selection.

The Role of Scrum in Agile

Scrum is the most common framework for the management of simple and flexible Agile projects. Recently, a lot of attention has drawn attention to the effectiveness of the approach. Almost all development companies have begun to promote Scrum to provide development services, although the approach is not the same. Scrum promotes the provision of feedback, self-organized development team, fully operational products in a short time. Developers who practice traditional approaches usually require a lot of time and effort to switch to real scrums, so special attention should be paid to these details when selecting developers.

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 Training

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).

Scale approach
  • 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.

Agile Method Opportunity

With the agile programming approach, developers can adjust the direction of the project during development and make changes to the software in the final stage. This is possible through periodic iterations or sprints (work periods), after the team has provided fully functional products or shipments of potentially shipped products. Agile software development is often described as incremental or iterative as each short work cycle increases.

Disadvantages of the Waterfall

On the contrary, in the development of the waterfall, the team can only offer the final product with rails once. Therefore, there is no room for errors and there is no opportunity to introduce changes. In the agile software methodology, all aspects of specifications, functions and designs are reviewed repeatedly throughout the life cycle. Periodically re-evaluating your project allows you to optimize your project and easily find ways to keep up with the latest trends.

High Quality Products in the Shortest Time

The agile methodology allows for inspection and adaptation approaches to introduce products quickly in the market and minimize development costs. You can forget problems such as analysis paralysis. This is because such methods of software design can not be done simply by gathering requirements together with the creation process. Work cycles generally do not last more than two weeks, so customers can change requirements and adjust the requirements for success in a constantly changing situation.

Agile development has the following advantages.

  • High quality products. In general, the agile creation of the system is a continuous review and revision. Because teamwork and the work cycle are short, errors and defects are more likely to be detected and corrected in a timely manner.
  • Share skills and knowledge When experts collaborate closely, they share the experiences of others, improve efficiency and improve productivity due to their interactive and interrelated capabilities.
  • Documentation is no longer essential. The need for documentation to improve the quality of the product and the exchange of knowledge is reduced.
  • More real work is done. Statistics show that developers are tired after 5-6 hours of programming when working with groups or agile couples.

Why use Agile?

  • Agile development allows developers to design the most effective solution in the shortest possible time. An approach ensures that the final product stands out among competitors through repeated iterations of software and continuous optimization. Developers who use above mentioned methodology will endeavor to polish the software after each iteration, add value and create perfect results for recognition.

A truly agile team selects and implements the most effective management and development methods for them. It is a difficult process to adopt this method, and you will hear many excuses as to why it will never work. However, the results obtained when the transition is successful are very valuable and motivating. People who look for reasons why they fail will return to the traditional methodology or practice the false agile.

Developers who will not Stop Improving

Excellent developers do not stick to a single methodology, can constantly explore new perspectives and find the best approach to individual projects. Since it is a progressive method, you must decide how to use it each time you start a new project. And that's what the agile development methodology is promoting. It is a philosophy based on continuous improvement. On the other hand, if you do not want to clearly understand future applications, their functions and requirements, and do not want to deviate from the plan, the waterfall is exactly what you need. Therefore, if you always want to work with ambitious, creative and talented developers who do not stop learning and improving, and constantly seek perfect results, please contact us. Always listen to your voice.
