One of the problems of software companies is the lack of the right structure for developing their projects. As a result, they have often produced such complex and nested codes that creating changes in one part of the project severely affects or disrupts other parts. Therefore, lack of the right structure for development makes it impossible to update the previous code and reduces the efficiency of the team to almost zero.

As a result, they have often produced such complex and nested codes that creating changes in one part of the project severely affects or disrupts other parts. Therefore, lack of the right structure for development makes it impossible to update the previous code and reduces the efficiency of the team to almost zero. The reason for this is the difference in coding and lack of structure and architecture. The development team must first agree on a set of rules and structures. Architectural patterns are not the result of a programmer's experiences; they have resulted from the experiences of hundreds of programmers and design professionals over years. These frameworks are not innovations or inventions, but are feedbacks on redesign and recoding that programmers have been involved with to achieve the highest levels of flexibility, extensibility and reusability.
