Before an application is made available to a wide audience, it goes through the appropriate environments, which allow it to be refined and ensure that it meets all requirements. However, for the entire cycle to run smoothly and without risk, additional mechanisms supporting the whole process are necessary.

How exactly does this work in the IT world? Let’s take a closer look at each of these stages.

What is DEV? Development – the chef’s kitchen

The DEV stage is where the first versions of the application are created – similar to a chef’s kitchen, where new recipes are tested. Developers write code, experiment with different solutions, and QA (Quality Assurance) specialists test individual functions, ensuring that everything works as intended. This is the phase of creative development and testing of new features, where one can experiment without fear of affecting the stability of the version available to end users.

When the code is ready, it must go through additional control mechanisms to ensure that the changes are consistent and do not introduce new issues. And here comes the next element of the process.

Continuous Integration (CI) – the chef’s automatic assistant

Every time you add a new ingredient to the recipe, you have an assistant who immediately checks whether the dish still tastes good. That’s how Continuous Integration works – every time a developer makes a change to the code, CI automatically runs tests to make sure the new functionality doesn’t disrupt existing components.

CI enables rapid error detection and immediate fixes, which speeds up software development and improves its quality. This ensures that only the highest-quality code moves on to the next stage.

What is UAT? User Acceptance Testing – a trial dinner for the team

Before the new dish reaches the guests’ plates, you organize a trial dinner for the team – chefs, managers, and waiters. You want to ensure that not only the taste but also the presentation, temperature, and serving time are at the highest level.

Similarly, in UAT, the application is tested by a group of internal users or client representatives. The goal is to check whether the solution is functional, usable, and meets real user needs. This is the last chance to introduce changes before the official “serving of the dish” – the deployment of the application to production.

If something doesn’t meet expectations at this stage, developers go back to the DEV stage to make the necessary adjustments.

What is PROD? Production – the dish on the restaurant menu

After receiving positive feedback from the team, the dish enters the restaurant menu. Everything must work perfectly, and any imperfection can ruin the guest experience.

It’s the same with software in PROD – production – where the application is available to all users, and any malfunction can directly impact their experience. Deployment to production requires full responsibility for the quality and stability of the application, which is why thorough testing in DEV and UAT is so important beforehand.

Continuous Deployment (CD) – seamless serving of the dish

Imagine having an automated system for serving dishes – once the recipe is approved, the dish immediately reaches the guests’ table. Continuous Deployment works the same way – once the code passes all tests, it is automatically deployed to production.

CD allows for fast and error-free deployment of new features, which is especially important in a dynamically changing business environment. However, to ensure that changes are safe and manageable, proper tracking of each modification is key.

Code versioning – recipes written in the cookbook

When creating new dishes, it’s worth recording each version of the recipe – if the new attempt fails, you can always return to the previous version. In programming, this is done through code versioning (e.g., using Git).

Code versioning is crucial for quality control and effective collaboration within the development team.

Do we have a backup? Protection against a kitchen disaster

Imagine that while working in the kitchen, you accidentally knock over a pot and the entire sauce ends up on the floor. Is dinner ruined? Not necessarily, if you’ve prepared an extra portion just in case.

In the IT world, this “spare sauce” is a backup – a copy of data, code, or configurations that allows you to quickly restore the system after a failure, human error, or hacker attack.

Backup is the foundation of secure IT infrastructure, which is why software houses use various strategies such as local copies, remote copies, and automated backup schedules.

Stable software is the result of testing, control, and safeguards

Software development is a thoughtful cycle of testing and improvements, supported by automation, version control, and data protection through backups. DEV, UAT, production, CI, CD, code versioning, and backups are key elements that ensure stability, security, and smooth deployment of changes.

Good software is not just code – it’s a well-designed process that guarantees stability, security, and high quality of the final product. Equally important is effective communication with the software house that leads the project and responds to business needs.

It’s worth choosing solutions and teams that take care of every stage of its development.
