RESEARCH METHODOLOGY AND SYSTEM DESIGN
This chapter discusses the research methods, respondents of the study, data gathering techniques, software development tools, and statistical treatment of data used in the development for the completion of the proposed study.
The reviewed literatures and studies gave the researchers ideas and information on how to proceed with the development of the system to benefit the target users. Through extensive research and the gathering of data, the researchers acquired knowledge and information that will be the basis of the study.
The research will be conducted at the New Era University during the final term of 1st semester ...view middle of the document...
The percentage formula includes the variable F, which means frequency response and variable N or the total number of samples. Mean was also used by the researchers which signifies the symbol X. To get the mean, get the summation or the total values of the iterations (X), divided by n, which is the total number of iterations. For the standard deviation formula, the variables used are X, which is the data or the number of passed data per iteration, variable X, which is the mean, and n, which is the total number of iterations created. The researchers also used the percentage error tool to compute the error from the computed standard deviation divided by the computed mean.
The researchers also used evaluation to test the usability criteria of the application. The tools used in computing the evaluation is the weighted mean formula. Weighted mean includes the variables X1 which is the number of respondents marked very poor, X2 which is the number of respondents marked poor, X3 which is the number of respondents marked very good, X4 which is the number of respondents marked excellent, Y1 for the rate of very poor, Y2 for the rate of poor, Y3 for the rate of very good, Y4 for the rate excellent and N for the number of raters. Four-Point scale was also used to get the rank or range of the computed weighted mean.
By using these statistical tools, the researchers were able to test the different criteria and get the experimental results.
Respondents of the Study
The researchers selected 5 domain experts to take part on the evaluations conducted by the researchers. The respondents were chosen by the researchers for the improvement of the system.
Software Development Procedure
The Ladder Model was developed by Team Source Code which is a group of students from New Era University enrolled under Software Engineering during the 1st Semester of Academic Year 2012-2013. It is a progressive model designed to meet certain specifications to be deemed by the client. It is a flexible model derived from various existing models, specifically the V Model and the Prototyping Model. It exercises the strengths of each model and utilizes each stage in progression depending on what result is made throughout the stage.
Ladder Model by Team Source Code
As you can see in Figure 3, there are 8 stages that comprise the model. The first step which is Requirement Analysis is where system requirements are identified for the necessary design and creation of the system/program. It is a joint effort by which the client and the company who will take on the project will specify the requirements by listening on each other’s proposals and specifications which in turn will produce a definitive contract. The next step is System Design. The flow of the system is created through the system design. This shows the step-by-step process by which the system operates through. After certain requirements are done in accordance with the contract, Program Design can now start....
