A) Top-down and bottom-up design may be employed in the same project.
Top-down and bottom-up are two approaches to the design of software architecture. In top-down, the high-level design is created first, focusing on general functionalities and structure. In contrast, bottom-up starts with detailed designs focusing on a component or module level.
[Reference: Sommerville, I. (2015). Software Engineering (10th ed.). Pearson., B) Top-down requires that details be ignored initially., In top-down design, architects focus on defining the overall structure and dividing the system into subparts without getting into detailed designs of components., Reference: Bass, L., Clements, P., & Kazman, R. (2012). Software Architecture in Practice (3rd ed.). Addison-Wesley., C) Architects leave the bottom-up design to developers., This statement is false because both architects and developers can be involved in both top-down and bottom-up designs depending on project requirements., Reference: Shaw M., Garlan D., (1996). Software Architecture: Perspectives on an Emerging Discipline Volume 1., D) Generally, architects should work top-down. - It’s generally advised for architects to start with a high-level view of the system to ensure that all stakeholders’ concerns are addressed before diving into details. - Reference: Rozanski N., Woods E., (2005). Software Systems Architecture: Working With Stakeholders Using Viewpoints and Perspectives., E) Bottom-up design means to proceed from abstract to concrete. - This is true as it involves starting from detailed components or modules then integrating them up into an overall system. - Reference: Hofmeister C., Kruchten P., Nord R.L., Obbink H., Ran A., America P.(2007). A General Model of Software Architecture Design Derived from Five Industrial Approaches., F) Different ideas about top-down and bottom-up approaches constitute a potential for conflict. - Different teams might have different preferences leading to potential conflicts but combining both approaches often yields optimal results. - Reference: Kazman R, , ]
