Once the requirements have been defined, the design of the finished system or product begins. This phase involves making technical decisions, modeling the intended processes, and planning the necessary resources , while determining how the various technical components will interact with each other to form a coherent system. In addition, during architectural design, functional specifications are broken down into technical specifications and the product's software architecture is defined.
Step 4. Detailed Design
Finally, the design phase concludes with the detailed design of each rcs data qatar of the product's essential components and how they fit together to meet the system's needs. At this stage, all functional and technical specifications must be defined and validated.
Step 5. Implementation
Halfway between the top-down and bottom-up phases, implementation transforms the specification and design documents into a functional system. In other words, it involves creating all the components needed for the system one by one and performing all the programming or construction tasks. In software development, this is the stage where the programming language is chosen before creating and compiling the code that builds the software.
