WATERFALL SYSTEM DEVLOPMENT LIFECYCLE
RESPOND TO QUESTION 1
The waterfall method is the primary system development lifecycle that is used in the
software design. It mainly constitute of a systematic sequential development of the product’s
lifecycle. The product lifecycle of the model have span of five stages and each stage will
have will be proceeded only when the previous phase is complete. The waterfall model make
sure that there is no overlapping of any phase that can lead in system overloading. The
outcome of the first phase is the input of the second outcome. The following steps are
involved in the Water System Development Lifecycle:
Requirement Analysis
This phase mainly describes the importance of all the requirements that are needed to the
desired software. The sufficient time is required to work on the phase by gathering the data
that could be related to the system design. It helps in the creating a better structure to input
data, analyse all the possibilities of advancement ,check and consider all the technical
limitation that can arise during implementation. It provide the blueprint of the process to meet
the client’s needs in the system development. The requirement analysis provides all the data
that can be used in the creating a proper budget to design a software. The requirement
analysis mainly consist of the two parts.
1. Vision document: The requirement analysis need the vision document to specify the
problem background, the main objective of the project and the probability of
achieving the success by the project. The vision document is the overview of the
project in understanding the benefits and potential risk that could be faced in the
future regarding the software.it is mainly used in order to guide the client the right
way to know about the project theoretically and suggest if there are any changes
needed.

2. Requirement gathering: After the requirements have been clarified through the vision
documents. The interviews, the survey, the questionnaire, the workshop are conducted
with the stakeholders of the software interface to keep a track of the requirements that
have been in use regarding the project. The requirement gathering help in giving a
better knowledge about the optimal resources that can be used in building the
software. It keeps the track of the additional requirement that can occur in the
development phase. The main use of the requirement gathering is to be prepared about
the additional requirement that can occur in future.
Software design Phase
The further step in the waterfall lifecycle is the software design phase, which mainly looks
through the project scope, the, vision documents and the exact time and budget that will
needed to implement the project in real.
1. Project Scope: The project scope helps in gaining the project description and
suggesting the main function that will be needed in order to create the creation of the
dummy projects to check the gathered requirements can be implemented to the project
and what resourcing and modification can be done in the project. The project scope is
the blueprint that is designed based on the vision documents. In this stage, the
developer must inform the client about the exact needs of the project that has been
deployed and tested.
2. Software Requirements Specification:
The software design needs the software requirements specification because the
requirements that are specified in order to implement the requested software. The
software specification phase makes sure that the requirements that are to be used
under the project are cohesive, consistent, traceable and complete. This phase specify
