1SYSTEM ANALYSIS AND DESIGN
1. Introduction
The case study of World Tour states that it is an online booking company and helps its
customers to take look about the tours they offer and book the tour if the customers wants to. The
main aspect of the case study provided is that the customer log in in the system of Would Tour
and search for different tours packages that are offered by the company. They can register
themselves in the system for booking a tour. The registered customers can make online payment
to book a tour after con firming the package. The staffs associated with the company works as a
tour guide and the system also has the information of the staffs so that the users can get an
information about the staff guide serving them. Another aspect of this system is administrator
who has the access to add tour details, modify them and delete them as per and change and also
manages the staffs information system.
2. Methodologies
System Development Life Cycle is considered as a process that is applied for developing
the information system projects ensuring all the functional as well as user requirements are
properly satisfied along with objective of the project and strategic goal of the project. This SDLC
approach of completing a project states all the structured as well as the standardized process that
are required for all the phases of the project in developing the project. The phases of SDLC
method helps to track the developing process of the system. There are three phases that are
included in the SDLC approach which are planning phase, defining phase, designing phase,
building, testing and lastly deployment phase.
Adaptive approach of system development states itself as a rolling wave for scheduling
the planning and helps to identify the milestone of the project. The adaptive method mainly

focuses on adapting the quick change realities and the changes in an adaptive method are done as
per the requirement of the user who are using the system. This approach basically does not
describe the exact process that will happen while developing the system or the software. Future
change are actually not listed in adaptive approach.
Advantages and Disadvantages: One of the most important advantage of adaptive
approach is that it allows the team to add the functionalities that are necessary for the project at
the time of developing the project. Implementation phase is mainly focused rather than the
functionality phase. As because of customizability, this particular approach also has drawback of
having re-usability. For each of the application in particular approach is to be used in different
way.
Predictive approach on the other hand is a SDLC approach that assumes all the project
planning and outlines the project deliverables at the beginning of the project. There is no way to
change the objective and scope of the project one the project is documented. The work of the
project will proceed as per the document states. This approach focuses on the planning as well as
analysing the detail of the project and encounters its own risks. All the features as well as the
tasks that are planned for this project development process can be tracked by the project team in
this predictive approach.
Advantages and Disadvantages: The first advantage that this approach has is that the
objective of this method is clearly defined as well as understood at the beginning of the project
itself. It also helps to measure system progress and minimizes the technical risks that can occur
in the system. This approach is very time consuming does not respond to any changes.
