• readiness for changes with following the original plan. Agile development approach requires plan, estimates and forecasts. If you have an initial annual project plan and provide some working product version in some months or requirements change while developing you can change the whole plan taking changes and feedback into consideration.

12 Agile development principles, also the result of the Snowbird meeting, expand these several value-defining proposals.

It's all. Since then, the website with the Agile Manifesto has hardly changed (or maybe it hasn't changed at all), which can't be said about the world around Agile.

Agile methodologies have enjoyed overwhelming popularity: first mentioned in the PMBOK (the US Project Management Body of Knowledge standard) 5th edition (2013), then they were fully adopted in the PMBOK version 7, released in 2021 which took all the Agile principles and became its direct ambassador.

To conclude with Agile introduction, it is necessary to state the main goal of this approach – delivering value to the consumer. According to Agile methodology, it is achieved using three characteristics for a software product:

Thus, the Agile method is applied to:

• accelerate the product launch to the market. If you want to develop software faster, you need to apply Agile. For example, two similar business companies. The first one creates the technical task for software development, designs the structure and interface consistently, this is a waterfall model, implementing it can take several months. Another team can already release a website and software applying Agile, start earning money and hijack the market;

• manage priority changes. An unpleasant challenge for almost all companies. Your requirements will definitely change if you are doing the project that lasts at least a few months.What about commercial development, the problem is that programmers, analysts and designers never know what customer who pays us and users need. The usual approach is: until the user tries the site or application, you do not know whether it is needed or not;

• improve cooperation between IT and business. This is a headache, especially for large companies. Business requirements change from time to time, everyone speaks their own language. As a result, the parties do not understand each other.

Before diving into Agile, it is important to learn terminology in order to lay the foundation for our understanding of this approach. We will analyze all the terms in more detail during the dive, so do not be afraid that at the very beginning they will seem abstract and difficult to understand:

The very idea of Agile is to learn how to work with the unknown and fill blank pages of our work due to an iterative approach (working on short sprints6 of 1-2 weeks).

This helps not only to keep up with the industry, but also to meet customer expectations and remain competitive.

Implementing Agile while building a software development process we start revealing practices:

• first of all Stand-Ups(Daily Stand-Ups)7. This is an easy practice: your team should meet regularly to synchronize the development process. Communication is key to developing effective teamwork, and poor communication can be one of the biggest reasons why a project fails in Agile teams. A daily stand up is a part of the agile methodology because it helps with improving communication among team members. Integrating effective communication with face-to-face contact as a part of the team’s culture helps in creating a more Agile workplace;
