DEVELOPMENT OF THE SOFTWARE

The next key stage in software development is the design stage, that is, modeling the theoretical basis of the future product. The most modern programming tools allow to partially combine the design and coding stages, that is, the technical implementation of the project, being based on an object-oriented approach, but full planning requires more careful and scrupulous modeling. A qualitative analysis of the prospects and capabilities of the product being created will become the basis for its full-fledged functioning and the implementation of the entire complex of tasks assigned to the software. One of the components of the design phase, for example, is the selection of tools and operating systems, of which there are very many on the market today. 

The next step is to work directly with the code, relying on the programming language chosen in the preparation process. It is hardly worth describing the features and subtleties of the most time-consuming and difficult stage; it is enough to point out that the success of any project implementation directly depends on the quality of preliminary analysis and assessment of competing solutions with which the created program will have to “fight” for the right to be called the best in its niche. If we are talking about writing code to perform highly specialized tasks within a particular enterprise, then the efficiency of the company that ordered the development depends on a competent approach to the coding stage. Coding can occur in parallel with the next stage of development - software testing, which helps to make changes as you write the code. The level and efficiency of interaction of all elements involved in the implementation of the formulated tasks by the development company is the most important at the current stage - the quality of project implementation depends on the coordination of the actions of programmers, testers and designers.

After the programmers have achieved their plans, the written code is followed by equally important stages of software development, often combined into one phase - product testing and subsequent debugging, which allows eliminating programming flaws and achieving the final goal - full-featured work of the developed program. The testing process allows you to simulate situations in which a software product stops functioning. The debugging department then localizes and fixes the errors found in the code, "licking" it to near-perfect condition. These two stages take at least 30% of the time spent on the entire project, since the fate of the software created by the programmers depends on their high-quality execution. Often, the functions of a tester and a debugger are performed by one department, but the most optimal would be to distribute these responsibilities between different performers, which will increase the efficiency of finding errors in the program code.

The procedure for introducing software into operation is the final stage of development and often occurs together with system debugging. As a rule, software commissioning is carried out in three stages:
