Boarding House Finder Thesis Documentation Chapter 3 : System Design

The research used two types of research methods in the study such as descriptive research and developmental research. It intends to determine the effectiveness of the system “Boarding House Finder”.

The Descriptive Research is used to describe characteristics of a population. Whereas, developmental research has been defined as the systematic study of designing, developing and evaluating instructional programs, processes, and products that must meet criteria of internal consistency and effectiveness.

Boarding House Finder Thesis Documentation Chapter 3 : Participants of the Study

The respondents of the study are the Tenants/users who wanted to find certain location of each boarding houses within their area. The end users include the administrator, expert group and the tenants/users of Boarding House Finder.

Table 2. Participants of the Study and Number of Evaluators

Table 2 shows the classification of evaluators and the corresponding number of evaluators per classification. Five Expert group, Twenty five Tenants/users.

Boarding House Finder Thesis Documentation Chapter 3 : Data Gathering Procedure

The proponents conducted a survey to determine the end users’ evaluation of Boarding House Finder application. One of the proponents distributed the survey questionnaire to the users and instructed the users to rate the developed system based on the criteria stated on the survey form. The users were given enough time to read, understand, and rate the proposed system. The proponents waited for the users to finish the survey and collected it afterwards for the computation of results.

The evaluation instruments used in the study were ISO Software Evaluation for the experts.

Boarding House Finder Thesis Documentation Chapter 3 : ISO Software Evaluation

ISO Software is a set of technical standards documents for the computer software development processes related business management function.

It is one of the point International Organization for Standardization (ISO) and International Electronical Commission (EIC) Standard which use developed by the ISO and EIC join subcommittee, ISO

Boarding House Finder Thesis Documentation Chapter 3 : Data Analysis and Procedure

To statistically compute the results of the survey questionnaire, the mean statistics are used.

In interpreting the derived weight mean, the hypothetical range with interpretation was applied.

Table 4 shows the verbal interpretation of the corresponding mean scores.

Boarding House Finder Thesis Documentation Chapter 3 : System Development Life Cycle

The system development life cycle is very important when developing a system. It guides developers on the different phases of the project which includes initial planning, requirements gathering, analysis and design, testing, implementation, evaluation and last is deployment. It is also used by the software industry to design, develop and test high quality software. The SDLC aims to produce high quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. The life cycle defines a methodology for improving the quality of software and the overall development process.

AGILE METHODOLOGY

The proponents used Agile model of methodology in developing the software which includes the phase of methods such as initial planning, requirements gathering, analysis and design, testing, implementation, evaluation and last is deployment.

Figure 1. Agile Model

Figure 1 shows the agile model that served as a basis for developing Boarding House Finder Android-based Application.

The proponents use the agile model to develop the propose system that allow to change the requirements when it is needed, enhance quality assurance and provide all the necessary ingredients for the best development of the system. It is a step by step process to meet goals and objectives of the propose system and to develop a system that provides reliable and secured important records.

Initial Planning

To start the first phase in the project development, the proponents set a meeting for project management of time, cost and scope. In time management, the project schedules are determined the task duration by creating the Gantt chart and time table. For the cost management, the proponents estimated the expenses that will be used during the development of the project. The project scope management it also applied in the initial planning of project, in part the proponents classify the methods, the scope and limitation of the project and the software and hardware that will be used in the development. After discussing about the project management the proponents assigning task and work in each member of the team. The proponents are also applied brainstorming and exchanging ideas for additional improvements of the project.

Requirements Gathering

In this phase, the proponent’s conduct an interview to the respondent of the system on what would be the activities that they performed in their daily work and to look for someone possible requirements of the propose project to different sources in order to sure the contents are all accurate. The developers gather all important suggestion and feedback that will used in developing the project. The proponents conducted research through the internet also to get some related system that could be help in the system. We make sure that all data that has been collected are used for the better result of the project development.

Analysis and Design

The proponents analyzed the information that has been gathered from the respondent for the requirements needed. The possible requirements are combined and analyzed in items of its strengths, weaknesses, and risks, defining the requirements of the second prototype, planning and designing the second prototype, constructing and consulting the second prototype to make the project well functions and to meet the customer satisfaction. This phase involves the construction of the actual project result, it also defining the overall system architecture. The proponents defined the important features of the project and collaborate the source of coding that will be used in the system.

Testing

In testing phase of the system, the proponents conduct a survey to the IT experts and respondent of the system to fixed some errors and select some additional suggestion. The survey represents as a summary of finding, conclusion and recommendation of the system. For testing, the proponents know if the system meets the objectives of the study and user satisfaction. After the project reconstruct, the proponents had perform testing and debugging until the final project is working.

Implementation

After a lot of testing made of the proponents for the proposed system, it is now the time for implementation to take place. The proponents implemented the developed system in different desktops or laptops and smartphones. The proponents also collected the feedbacks of users after they experienced on how to use the propose system. The feedback that has been collected are used for the some changes of the functions and features. But some of their suggestions are not implemented because it is out of our project.

Evaluation

The proponents conduct an evaluation for the acceptance of the user and know if they are satisfied to the propose system. Some of the evaluators give their suggestions and recommendation for the new Improvement of the system. The gathered feedback from the users and customers through conducting a survey and evaluation weather to consider any changes in the functionalities of the features of system are applied by the developers for the satisfaction of respondents and meet the objectives of the study.

Deployment

In this phase, the proponents take up a final defense to test, if the systems are now ready to used and put into the public. After the final defense the proponents changes some of the function that requested or suggested by the panels to make sure that the system are capable for the deployment in the organization selected. The proponents make sure that all functions and features are fixed and totally 100% running system. The system will be used with the possible users and maintenance will be part of the developers to be done.
