INTRODUCTION In order to examine the problem and its solution, System Analysis and Design concept uses.It helps in reviewing the issues from all aspects so that it becomes easy to proposed more than oneoption to resolve the identified difficulty (Satzinger Jackson and Burd, 2011). With the help of this,a system can be analyzed by examine its components and its interaction with the other systems.System Analysis and Design also know with the name of Object Oriented analysis and design wherea system creates for a particular application or a purpose (Glover Sarma and Overbye, 2012). Underthis, the requirements of the users transform into a program with the use of hardware and softwareprogramming. The present study is based on System Analysis and Design and to understand itssignificance, a leading travel agency case study is taking into the consideration. In recent time,company is facing the problem related to competitions in the market and to compete as well assustain in the marketplace, it has decided to develop application software. The aim of this project isto help the customers in planning tours, solve the queries of service users related to transportservices, hotels etc. This will also facilitate the agency for billing and accounting. TASK 11. Evaluation of SDLC model for 'Travel Agency: Automated Tourist System' projectFor creating an automated platform a team of testers, coders, architects, analysts,etc. Is setup and they work all together to develop one particular system. This application or systemdevelopment life cycle is based on the planning, testing and innovation of a particular informationsystem (Coronel and Morris, 2016). The term is abbreviated as SDLC that is system developmentlife cycle in information technology. The different types of SDLC models are described below:1.Waterfall: This model works on the basic principle that output of one stage would be theinput for another stage; but the success rate of this model is the least and doesn't help indevelopment of the company.2.Fountain: According to this model, different activities require different start points whilesome stages cannot be initiated before the previous stage. Hence, the complete cycle facesan overlap of activities. 3.Spiral: The model where a chain of stages are to be repeated according to the demand of thecycle is a spiral model. Here, a small prototype of the actual concept is produced at thetermination of each short cycle and this can lead to chaos.4.Build and Fix: A risk oriented and unplanned model is the build and fix model. Codes arebuilt on the wishes of clients and improved until he is satisfied. This can be a time3
consuming and wasteful method sometimes because rewriting changes in a long code isinvesting more time and resources.5.Rapid Prototyping: Creating a sample project that functions just like the original or proposedone, for testing the durability of the product is rapid prototyping model. This is a form ofprecautionary measure that can be taken before investing on resources for developing theoriginal one. The success of the prototype ensures success of original software.6.Incremental: A much better and effective model is the incremental. The complete projectcycle is divided into fragments, where separate teams work. The testing and development ofdifferent parts is done efficiently with better error reduction. 7.Synchronize and Stabilize: This model was used by huge technology giants for developingtheir projects. The synchronize and stabilize model works on the advantages acquired by thespiral model and combine it with technology. The only effort that was required in thiscategory was controlling and inspecting the complete source code from time to time.The rapid prototyping model of SDLC would be recommended for 'Travel Agency:Automated Tourist System' project. As the company would be dealing with the consumers on a realtime basis, the prototype will help in understanding the important aspects that are to be covered inthe application software. The basic intention of the application software is to enable customers forperforming various tasks like reviewing, booking and planning their tours through the company(Dhillon, 2013). Once, the prototype is launched the company will be able to understand the defaultareas that are creating problem for the consumers. For example, processing delay, high responsetime, etc. are the limiting factors that can be overcome. Once, the prototype is successful, thecompany can launch its real time software.The Analysis Phase is the beginning condition of a project. No project is started without ananalysis. This phase consists of collecting the complete information and statistics regarding theproject strategy. Various processes are involved in this phase like capturing, documentation,communication and managing all the resources that will be needed for defining the code of theproject (Valacich, George, and Hoffer, 2015). It is essential part of the project life cycle asaccording to the results of this phase the complete structure of the project is designed andimplemented.A System Analyst is an individual who has the abilities or specialization in en-lacing,designing and implementing information technology for a given project (Stark, 2015). This personis like bridge between the analysers, testers, coders and software vendors so that he can havecomplete access to the required information. Any strategical changes that are needed in the systemdesign are proposed by this individual. Apart from developing the software or hardware programs4
