My application is already on the market. What factors determine that it is developed over a long period of time?
Three key factors determine whether your application is expandable over a long period of time.
First of all, the right application architecture. You should always remember that the application should be testable and that it should be divided into testable components.
Secondly, the application should have detailed documentation that would allow for a quick takeover of the project by another developer who was not involved in the project before.
Thirdly - product development. The key is proper synchronization of work between the developer team and people who are responsible for the long-term development of the product. It is important that each party understands the division into individual versions of the application, knows the dates of delivering the elements and knows how to effectively maintain the project. If you take care of these three elements, you can be sure that your application will be developed over a long period of time.
Modern software development methodologies that we use when implementing projects will be useful:
BDD (Behavior Driven Development) - a methodology that avoids problems related to poor understanding of requirements by individual team members. Thanks to BDD, from the moment of collecting the requirements and documenting them with examples, all the people involved, both on the Leaware side and on the client's side, understand the challenges that we have to face in exactly the same way. It is also important that the collected requirements become also acceptance criteria, which helps in measuring the quality of the delivered project and the degree of its implementation.
DDD (Domain Driven Design) - a methodology that allows you to create a solution architecture in such a way that it is simultaneously related to its implementation. Thanks to this, along with the development of the product, we do not lose control over its architecture, which can be constantly adapted to the changing needs of the client.
TDD (Test Driven Development) - a methodology that, in combination with BDD and DDD, allows for continuous testing of the solution being created and minimizing risks associated with regressions, as well as architectural changes.
