Once you have chosen your language, design a detailed software architecture describing the structure of the system:
Components: Identify the major parts of the system that will be separate components. For example, in a database management system, this might include components for user management, data management, etc.
Subcomponents: Divide each identified component into smaller subcomponents. For example, a user management component could include subcomponents for authentication, authorization, etc.
Classes and Objects: For object-oriented components, define the associated classes and objects. Specify the properties and methods of each class.
Algorithms: Detail the specific algorithms for the components that require them.
Technologies: Select the technologies and tools that will be used to implement each component (databases, frameworks, programming languages , etc.)
Interfaces: Detail how components interact with each other (communication protocols, inputs, outputs).
User Interface (UI): Develop the detailed designs of the user interface (layout of elements, navigation, etc.).
Errors: Plan for error handling at every step. Identify scenarios where errors can occur and define how the system should respond.
Security: Identify areas where security needs to be strengthened.
Performance: Ensure the architecture is designed for optimal performance. Refine the design as needed by including efficient data structures, optimizing queries, etc.
Consider documenting the architecture so that team members can understand and follow it. This may include creating flowcharts, UML diagrams, schematics, and other explanatory documents. Also, produce detailed documentation for each component: complete descriptions of business logic, algorithms, data structures, etc.
Become a designer (or hire one)
Once the foundations and structure are ready, it will be necessary to give your creation a shining light. Many software programs fail their audience due to a lack of “beauty” or responsiveness/maneuverability.
This step is time-consuming because it requires extreme attention to detail. All graphic elements must be tested and retested, then wrapped in the most elegant graphic interface possible to promote what is known as UX (User Experience). Think about the layout of elements, navigation, colors, and so on.

Implement the code and integrate the software components
You can now begin implementing your code following the guidelines established during the architecture stage.
Remember to follow good coding practices to keep your code modular, readable and reusable.
For each individual component, perform unit tests to verify that it works correctly in isolation.
Gradually integrate the various software components, testing as you go. Ensure that the entire system is working properly.
Have you finished implementing the code for all the components? Do you think your software is finished? Wait a minute… have you tested it thoroughly, up and down?
The validation testing phase is crucial to verify that the software meets the requirements initially specified.
You’ll need to conduct multiple tests to uncover and track down any bugs that are bound to pop up. They can take many forms, but you’ll need to fix them all! Features, performance, and more must be considered. Nothing should be left to chance.
