What are the 7 phases of waterfall model?
The waterfall model is a sequential design process in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance.
What is implementation phase in waterfall model?
The Implementation phase is when all of the actual code is written (“SDLC Phases”, n.d.). This phase belongs to the programmers in the Waterfall method, as they take the project requirements and specifications, and code the applications.

The Phases of Waterfall Methodology The Waterfall methodology is broken into seven stages, and each stage is completely dependent on the previous ones. This process can be planned using a Gantt chart, which is a linear bar chart that shows the start and end dates for each task.
What is inception phase?
An “inception phase” is a dedicated period at the beginning of a program that is focused on learning and better understanding the context for implementation. Development professionals across all sectors are increasingly turning to inception phases to conduct and apply learning from the start.
What is inception phase in Unified Process model?
The Inception Phase is the first phase the Unified Process Lifecycle. Its purpose is to establish a shared understanding of the opportunity and the business case for producing a solution before committing to the solution’s development.
