Systems Analysis And Design Methodologies_2

INTRODUCTIONSystem analysis refers to process of scrutinising business or processes for identificationof their goals along with their purpose for creation of procedures and systems for attaining themwithin effectual manner (Dennis, Wixom and Roth, 2018). It is associated with analysis ofrequirements for assisting decision makers for identification better actions that have been carriedout. The case study is based on QuickCabs which is a online organisation and renders theiremployees to book as well as pay for services. Individual can look forward for taxis withinwebsite and when bookings are made the details of customer will be checked to identify whetherthey are existent or new. Unique ID along with password will be provided to new customers forcarrying out their transactions. Being a system analyst the system must be designed in such away that new customers can be added and transactions related with same must be carried out. Inaddition to this, there needs to be an option with an administrator for adding, deleting ormodifying information related with taxis and driver. MethodologiesSDLC (System Development Life Cycle)A conceptual model that comprises of procedures as well as policies for development ofaltering systems within their life cycles is referred to as SDLC (Dennis, Wixom and Tegarden,2015). Basically, it renders framework for technical as well as non-technical activities fordelivering quality systems for meeting or exceeding expectations for managing decision making.QuickCabs can utilise its phases for breaking down their system or formulate new as per theinformation. These stages are illustrated below:Planning or feasibility study: In this the problem will be defined for an instance withrespect to QuickCabs, administrator needs to alter details associated with taxis or driver.This denotes there is scope for improvisation in their existing systems. The objectives ofdefined system must be clarified so that there must be an overview of all the aspectswhich have to be performed. Security aspects must also be taken into consideration bysystem analyst and at the end feasibility report must be created (System DevelopmentLife Cycle, 2019).1
