Tools and Equipment Monitoring System Methodology

This Tools and Equipment Monitoring System Methodology presents the system design of the proponent’s system.

SYSTEM DEVELOPMENT LIFE CYCLE (SDLC)

The Software Development Life Cycle (SDLC) is very important in developing the system since it can help us to know how to use a process for planning, requirements analysis, testing, evaluation and deploying an information system. The SDLC is used as a guide in developing the project, planning and analyzing in which the processes are in step by step procedures.

The concept of SDLC applies to a range of hardware and software configurations, as a system can be composed of hardware and software only, or a combination of both. This space is done by step by step and was used repeatedly to accomplish the final project.

RAPID APPLICATION DEVELOPMENT METHODOLOGY

Figure 1: Rapid Application Development Methodology

Figure 1 tells from the beginning of the research up to the last process. RAD model distributes the analysis, design, build and test phases into a series of short, iterative development cycle. RAD makes heavy use of prototyping to make sure interested parties have a clear picture of all aspects of the system.

Rapid Application Development is easy to use as a methodology the diagram shows the step by step so that the problems that might encounter can be polished by reviewing every step. In RAD, the functions are developed as the prototype is being integrated to make the complete process quicker it makes it easier to incorporate and understand the changes within the development.

Analysis and Quick Design

In this phase, the proponents analyzed the data they gathered and created a design that is suitable for the processed for Tools and Equipment Monitoring System.

Business Modeling

This phase of software development is the stimulant of the proponents to plan a software that will aid the construction company. The proponents conducted an interview and observations on how the staff doing their job in a period of time. Then, proponents asked for the process they’re doing manual when it comes to inventory and the proponents found out a problem and a need that can be addressed by the proponent’s system.

Then proponents had sited different platforms to be used for the entire development of the system that can attain the objectives of the study.

Data Modeling

In this phase, the information that has been gathered from business model is being analyzed to form a set of data objects deemed very important all throughout the process for developing a system. The relation between these data objects are established and defined in detail in relevance to the business model.

Design Modeling

In this phase, the proponents developed a design which is user-friendly and can obtain an easy access to the field requested by the user and since one of the features of the system is web-hosted, proponent used the standard mark-up language for creating web-site or the HTML, and for the design or the CSS.

Process Modeling

In this phase, the data object sets are being executed to start the first process which is establishing the business information flow needed to achieve specific business objectives as per the business model. The process model for any changes or enhancements to the data object set is defined in this phase.

In line with this stage of development, the proponents had created some of the methods for the system’s processes, however the proponents had been encountered some problems while developing these processes. Yet by the availability of the information on the internet. And in agreement to this stage, the proponents had also sought for some of the further inputs vital to the system and formulate further processes. Furthermore, knowledge in programming and logic were really needed to attain this stage.

Application Generation

Generating the actual system is being describe in this phase, by using automation tools for the process to be converted into actual prototype.

The over-all development of the system in both front-end and back-end has been developed using PHP since PHP file contain text, HTML, CSS, JavaScript and PHP code. The proponents used this platform via Sublime Text Editor and for the database of the system, the proponents had used Structured Query Language specifically MYSQL using PHPMyAdmin. But during the development of the system the proponents used local hosting using XAMPP- Apache Server.

Testing and Implementation

     This phase is the actual testing of the actual prototype, to be able to fix suddenly if there is an error found. The overall testing time is reduced in the RAD model as the prototype is independently tested during iterations.

     At this stage, the proponents will conduct a series of testing of the system to the user, however, in every test done by the proponents, the user/s suggest further changes of lay-out of the system. The proponents took a lot of testing and checking until it reaches the maximum user’s satisfaction.

Data Gathering Procedure

The proponents conducted a survey to determine the end users’ evaluation of Tools and Equipment Monitoring System. 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.

Research Instrument

     Tools and equipment monitoring system use the PSSUQ Questionaire it is widely used to measure users’ perceived satisfaction of a website.

Respondent of Study

     The respondents of the study are the person who are working in the construction companies for the user evaluation and for the expert we have IT expert inside the campus.
