DEVELOPMENT OF THE SOFTWAREby Xozepew Usaz We are always in the lead! The development of any program, be it a small procedure for processing information coming to the console or a complex software product, consists of several stages, the competent implementation of which is a prerequisite for obtaining a good result. Accurate adherence to time-honored software development milestones is becoming a fundamental criterion for software companies and their customers interested in obtaining a program that performs excellently. Let's take a closer look at each stage of the generally accepted software development methodology in order to assess their high significance for achieving the goal set for the performers.
The very first stage of software development is rightfully called the procedure for conducting a comprehensive analysis of the requirements put forward by the customer for the software being created in order to determine the key goals and objectives of the final product. As part of this stage, the most effective interaction between the client in need of a software solution and the employees of the developer company takes place, during the discussion of project details helping to more clearly formulate the requirements for the software. The result of the analysis is the formation of the main regulations on which the performer will rely in his work - technical specifications for software development. The TK should fully describe the tasks set for the developer and describe the final goal of the project as understood by the customer.
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.
Testing and Debugging
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:
initial data loading;
gradual accumulation of information;
bringing the created software to the design capacity.
The key goal of the step-by-step implementation of the developed program is the gradual identification of previously undetected errors and shortcomings in the code. As part of this stage of software development, both the customer and the contractor may encounter a number of rather narrow range of errors associated with partial data mismatch when loading them into the database, as well as disruptions in the execution of software procedures due to the use of multi-user access.
It is at this stage that the final picture of the user's interaction with the program crystallizes, and the degree of loyalty of the latter to the developed interface is determined. If the system reached its design capacity after a series of improvements and improvements was made without any particular complications, then the preliminary work on the project and the implementation of the previous stages of development were carried out correctly.
The creation of even small and technically simple software depends on the precise execution of each phase, that is, the activities of all departments involved in the development process. A clear plan for the implementation of the necessary measures with an indication of the ultimate goals is becoming an integral part of the work of developers who plan to remain highly demanded specialists in the labor market. Only a correctly drawn up technical task will allow achieving the desired result and developing truly high-quality and competitive software for any platform - server, stationary or mobile.

P.S.: An integral part of the final stage of software development is also subsequent technical support of the created product during its operation at the customer's enterprise. A well-organized technical support service often becomes a key factor in choosing a contractor in order to achieve a set goal.
