The software lifecycle describes the entire process of developing individual software until it is completed and handed over to the customer. Of course, there are different phases in between until the end of the lifecycle or before it starts all over again. In this article we would like to explain to you how this process works in its individual parts! If you need further information or help with the creation of your individual software - we are happy to help you at any time and with all questions.

1. an overview of the software lifecycle

The software development lifecycle usually starts with a problem that needs to be solved by a software. Mostly this problem arises on the side of a company, which usually does not deal with the development of an individual software. So the next step is the contact between the company and a software agency.

At the software development agency, the problem is analyzed together with the requesting company and the implementation of a solution is planned. Then it goes to the implementation and development of the code.

The software agency will now test and improve the individual software until it is finally used by the customer. The life cycle of the custom software ends when the previous software is replaced by a successor software, which starts the life cycle all over again.

In the course of development within a life cycle, developers can follow different procedural models, which should, however, lead to the same result in the end: A functional individual software that can be handed over to the customer.

2. different procedure models with the software development

The life cycle of an individual software includes above all the IT software development. This is because preparation and planning prepare the development, and even when it is completed, programmers always come into play to maintain or improve the software. Another big part of the lifecycle is, of course, the time when the custom software is simply used for its intended purpose. How the programming within the life cycle then really happens can be described in various procedural models.

We would like to take a closer look at the process models that are used in the software development process and ensure a controlled flow from the conception of a software to its actual use in a company. For example, developers use these two models: the waterfall model and the spiral model. In addition, there is also the so-called V-model. The structure of the approach resembles the letter V, which is why it is called that.

• The Waterfall Model

In the waterfall model, the individual successive phases are strictly separated from each other. As in a multi-stage waterfall, findings from the previous stage "fall" into the subsequent stage. In this stage, they are binding specifications that must be observed during processing. Thus, first planning, then development, then testing and so on.

• The spiral model

The spiral model is about repeating the same work step more often. So a function is developed, tested and improved. These steps are then carried out for each subsequent function, so that the results are already almost perfect at the end of a work step.

• The V-Model

The individual phases of software development go into more and more detail: from the analysis of the general requirements of the software and planning of the system architecture to the system design and the detailed conception of the system architecture. Then the actual software development starts. Then the planned features are implemented, tested, integrated into the system and finally accepted by the customer.

3 The end of a software life cycle

Once a software has been fully programmed and integrated into a company's operations, the life cycle does not end until the software needs to be replaced by another. Usually, the software has been in use for a long time before that and has often been adapted and updated to meet new technological requirements. At some point, however, it may happen that this is no longer sufficient and the software has to be completely replaced. Then the life cycle of the old software ends and the life cycle of a new individual software begins.
