This first step involves gathering and formalizing stakeholders' business and system requirements, which are actually an expression of the client's needs. To do this, the project manager typically conducts a feasibility study where all stakeholder expectations are patiently detailed. This allows for a solid foundation to be laid for the project. Indeed, the needs analysis phase determines the specific features and requirements that will guide the entire product development process. It is therefore essential to dedicate sufficient time to this step.
Step 2. Specification or Analysis
In the V-cycle method, specification consists of summarizing the client's requirements to write the functional specifications or functional specifications. This documentation describes the client's expectations and the technical constraints to be met without going into implementation methods. This ensures that the system meets the needs defined by the client.
Step 3.
Once the requirements have been defined, the kenya phone number lead 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 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.
Step 6. Unit Testing
This is where we enter the third phase of the V-cycle, or validation phase. This phase corresponds to the quality assurance associated with each of the development phases carried out. Thus, unit tests, which are carried out at the code level for IT projects, allow errors to be detected and corrected early in the validation process for each individual component.
Step 7. Integration Testing
Integration tests are carried out at the level of the developed functionalities and aim to guarantee that once assembled, the technical components constitute a functional system which respects the technical specifications drawn up during the architectural design.
Step 8. System Tests
Then, system testing, or functional testing, verifies that the system meets both business and system requirements. This involves testing the entire system in a real or simulated environment to validate its performance against the initial requirements.
