SYSTEM ANALYSIS AND DESIGN1
Introduction
The case given is the case study of QuickCabs. This is an online company and provides
the customer to book the taxis online and pay for the taxis. The online service provided by
QuickCabs helps the customer to search for cabs online and book for the cabs. The customer
needs to sign up as new customers and only after sign up they can book a cab only after they get
a unique id and password for login. For transaction with the QuickCabs, the customer need to
enter the unique password and ID in the system.
The report below states the methodologies that are included in the life cycle while
developing a product. Two methods of SDLC are explained in the report below stating difference
between predictive SDLC and adaptive SDLC. The usefulness and the limitation of both the
approaches are also mentioned (Geisser 2017). A particular model is chosen for the case study
and this is explained in the report. A requirement finding technique is also suggested for the case
study so that proper business requirements can be gathered and proper specifications is to be
given for the system development (Rossiter 2017). The requirements including the functional
requirement and the non-functional requirements are also included in this report. Based on
requirement analysis, requirement modelling is done based on one particular use case of the case
study. The activity diagram of a use case is also explained in this report.
Methodologies
The SDLC method includes series of phases helping to understand the building process
of a system or a software. This method includes the development of the software and
understanding the process of business and includes the phases of requirement as well as the
features that are used for system usage. The operations for developing the system is also

explained in the SDLC method so that the business need is satisfied. This is an industry standard
approach that helps in managing the project successfully.
Predictive approach of SDLC includes approach that includes planning of project that
can be outlined at the beginning of project and helps in producing the new information system
and develop the system as per planning.
Advantages of predictive approach of SDLC includes that in this project, the objectives
of the project are defined clearly and are well understood. This method also has some other
advantages (Li et al. 2015). This helps to measure the progress of the system. There are less
probability of technical risks using the predictive method of SDLC approach. This method is
advantageous for developing a system software.
Disadvantages of predictive approach includes that this method is time consuming as all
planning included in the developing the system are to be planned before the project starting. This
method cannot be taken backward and this method does not have enough space for iteration and
does not respond the changes in the development process.
Adaptive approach of SDLC states that the project included in adaptive method are
more bendable and helps to acclimatize the altering needs of the project. One of the key methods
of adaptive approach includes rolling wave which includes schedule planning and helps to
identify the milestones and makes the project more flexible.
Advantages of predictive approach of SDLC allows the developer to add all the
necessary functionality that is included in a project development (Wang, Xiao and Lee 2015).
This includes avoiding of time for the project development. This approach mainly focuses on
implementation of the system instead of concentrating on the functionality of the application.
