INTRODUCTION

Since the advent of mobile technology, the process of storing information, managing records, and interacting

with stakeholders has undergone radical changes. Smartphones and mobile applications used throughout society

enable institutions to send timely information, increase operational effectiveness, and increase user engagement

using digital environments (Laudon & Laudon, 2020). Communities in the form of churches are increasingly

encouraged to engage mobile technology to promote communication, maintain appropriate records, and connect

more strongly with members (Hutchings, 2017). Indeed, many local churches, including the New Testament

Christian Church (NTCC), employ the traditional modes of communication and management, such as oral

announcements in the form of church services, paper-based documentation, and scattered social media usage,

despite these technological advantages.

Despite their efficiency and effectiveness, these methods have historically resulted in irregular information

sharing, information delay, data redundancy, and poor access to church-related information for non-

communicated participants who are unable to attend more regularly (Goh & Cheong, 2019). This calls attention

to the requirement for a centralized and efficient digital means of delivering a modern church service. To alleviate

these issues, the NTCC church mobile application was created to unify key functions in regards to church

managing and communication in one platform. It also combines features like sharing daily devotion, centralized

announcements, event scheduling, profiling of members, and tracking of donations.

The integration of such services into a mobile application would facilitate better organization, visibility and

information-related information for all members, facilitating immediate access for participants (Pressman &

Maxim, 2020). Additionally, the mobile app serves as a logical and user-friendly platform that helps churchmen

and women to better manage church affairs. With role-wise access and digital records handling the system

minimizes the need for manual work and minimizes data loss or false information. This research thus aims to

determine if the NTCC Church Mobile App is effective, usable and acceptable in its general adoption as a digital

tool to overcome the challenges pertaining to communication and management of the church.

Objectives of the Study

The general purpose of this study is to design and develop a comprehensive mobile application for NTTC

Churches, serving as a digital solution for management and communication. Specifically, it aims to achieve the

following:

1. to identify the existing processes in NTCC's Church management and communication,

2. to identify the difficulties and challenges currently faced in NTCC's Church management and

communication,

3. to develop features that could be integrated within the development of the System; and

4. to determine the acceptability level of the developed system.

METHODOLOGY

A descriptive developmental research design guided the study, focusing on examining current NTCC church

processes and developing a tailored mobile solution to address identified issues.

Applying the RAD methodology enabled efficient delivery of a functional Church Management system

prototype that met identified requirements. Early and ongoing user involvement led to improved design usability

and ensured alignment with user needs. The iterative construction process helped quickly identify and resolve

issues, enhancing system quality and acceptance. Stakeholders reported satisfaction with the system's features

and its usability, attributing this success to RAD’s collaborative and flexible development approach.

The needs planning phase is the starting point. At this stage, the stakeholders and developers get together to have

open conversations about the system's objectives, the problems it should solve, and the features that are essential.

To understand the true needs and experiences of the consumers, the team collects data through surveys,

observations, and interviews. This step is important before any development begins since it helps everyone agree

on the system's direction and aim. The User Design phase involves close collaboration between developers and

users. Instead of waiting until the system is finished, developers create early concepts and rudimentary

prototypes that consumers may review immediately. We encourage comments, suggestions for improvements,

and the identification of any ambiguities. This active participation guarantees that the system is easy to use and

that its functionality and design truly live up to user expectations. Throughout the prototyping, testing, and

refinement phases, the system is constantly developed throughout several cycles. Users develop and test a

working version of the system to identify flaws, usability problems, or missing features. In response to user

comments, the system is updated and enhanced. This cycle is repeated until the system is reliable, stable, and

user-satisfying in order to prevent major issues before final deployment. The system is completed during the

construction phase. Developers focus on writing the final code, integrating all system components, and

implementing the approved features. Since most design difficulties were already resolved in earlier stages,

development during this phase is more organized and efficient. Ongoing testing is also carried out to ensure that

each system component functions as intended. The Cutover phase marks the end of the system's actual use. This

phase includes final testing, data preparation, and user training to make sure everyone is ready to utilize the

system. Once these procedures are completed, the system is officially deployed and made accessible to users.

The system is currently fully operational and ready to help with real tasks.

Figure 1. Rapid Application Development Model

Purposive sampling selected 21 participants: the church pastor (1), church leaders (5), church members (9),and

first-time attendees (6), all from NTCC Tiep Bani.

In this study, we utilized data collection from many dimensions such as interviews, questionnaire-based surveys,

and internet research data. These data collected from such a range of sources offered ample opportunity to have

a comprehensive account of data generation. Different analytic devices were employed to analyze and illustrate

the system's design and operation. Entity relationship diagrams were created to represent associations among

entities in data to assist in designing and organizing the database. The flowchart representation was helpful to

describe the operations and workflows of the system, facilitated process mapping and potential improvements.

Quantitative measurement techniques were used to assess the system acceptance and usability. Average scores

were calculated based on the weighted mean, which accounted for the relative importance or frequency of

responses, making it possible to get a more nuanced insight into user feedback. A Likert scale was employed as

a standardized method to gauge participant attitudes and perceptions towards the system – a scale from strong

disagreement to strong agreement with the statements. These measurement tools jointly provided helpful insights

into overall acceptance of the system, emphasizing strengths and areas ripe for improvement from the users’

perspective.

The analysis of the ISO/IEC 25010 Acceptability Test responses allowed the researchers to gain meaningful

insights regarding the effectiveness of the NTCC Church Mobile App. A review of existing communication

platforms such as Facebook Messenger and other social media tools revealed common limitations in managing

church-related information, such as scattered announcements and delayed communication. These findings

guided the development of the system to better meet the needs of church leaders and members by providing a

centralized and organized platform.

The development team utilized Android Studio for mobile application development and integrated Firebase

services for real-time data management. The system interface was designed to be simple, clean, and user-friendly,

ensuring accessibility for users with different levels of technical experience. Firebase enabled real-time updates

for announcements, events, and user data, ensuring that members receive accurate and up-to-date information

anytime.

A Fishbone Diagram was also used to analyze and identify the root causes of the problems in the existing church

management system. The analysis revealed several issues such as unorganized member data, inconsistent

communication, lack of centralized information access, and dependence on multiple platforms. These challenges

resulted in delays, confusion, and reduced engagement among church members. Based on these findings, it can

be concluded that the existing system is inefficient and unstructured, which justified the development of the

NTCC Church Mobile App as a digital solution to improve communication, organization, and overall church

management.

As a result of these identified factors, the development of the NTCC Church Mobile App produced a system that

effectively meets the needs of both church leaders and members. By addressing the key challenges in the existing

communication and management processes, the application provides a centralized platform for announcements,

events, devotional content, and member information. This system enhances accessibility, improves information

dissemination, and promotes better engagement among members of the New Testament Christian Church,

ultimately contributing to a more organized and efficient church management experience.

RESULTS AND DISCUSSION

The Three-Tier Architecture is a well-known and effective architectural model that consists of three main layers:

the presentation tier, the application tier, and the data tier. The presentation tier is responsible for the graphical

user interface, the application tier handles the system’s logic and processing, and the data tier is used for storing

and managing data. The NTCC Church Mobile App utilizes this three-tier architecture to ensure better scalability,

organization, and maintainability of the system (Chiaramonte, 2024).

Users can access the NTCC Church Mobile App through their mobile devices, as shown in Figure 3, which

represents the presentation tier. This layer allows users to interact with features such as announcements, events,

daily Bible verses, and member profiles through a user-friendly interface. The application tier handles the core

functionalities of the system, including user authentication, role-based access, and processing of requests using

Firebase services. Meanwhile, the data tier utilizes Firebase Firestore to store and retrieve data such as user

information, announcements, event details, and other system records in real time, ensuring data consistency and

reliability throughout the application.

Within the Presentation Tier of the NTCC Church Mobile App, the user interface serves as the main gateway for

church members, leaders, and administrators to interact with the system. Members can easily view

announcements, access daily Bible verses, and stay updated on upcoming church events, while administrators

can create events, manage announcements, and monitor user activity. This layer also includes essential functions

such as user login, navigation, and access to different modules, making it the primary point of interaction for all

users.

User actions such as viewing announcements, accessing event details, and updating user information generate

requests that are processed by the Application Tier through Firebase services. This layer handles the system’s

core logic, including user authentication, role-based access (admin and member), and processing of data requests.

Firebase Authentication ensures that only authorized users can access specific features, maintaining system

security and proper data handling.

The Data Tier serves as the storage component of the system, where all important data such as user profiles,

announcements, event details, and system records are securely stored. Firebase Firestore is used to manage and

retrieve this data in real time, ensuring that any updates made by the administrator—such as new announcements

or events—are instantly reflected in the users’ interface. This real-time capability improves the reliability and

responsiveness of the system.

By utilizing the Three-Tier Architecture, the NTCC Church Mobile App achieves a well-structured, scalable,

and efficient system design. This approach allows the application to handle increasing user demands while

maintaining performance and organization. For future enhancements, improvements may include refining the

user interface, adding more interactive features, and continuously gathering feedback from church members to

ensure that the system remains aligned with their needs and expectations.

CONCLUSION

Innovation is to improve organizational efficiency that allows for bringing in the latest solutions to existing

challenges and improving our service delivery. In church management, digital innovation means that a religious

institution is more or less current, organized, and responsive to the needs of its members. In order to save time,

we came up with NTCC Church Mobile App as a solution for the New Testament Christian Church managing

and communicating effectively which provided information where it needed to be in its different systems as they

have scattered information, announcements that don't appear in a timely manner and still have been left to get

by on a semi-agile and fragmented basis.

Having integrated unified mobile application, it can support a good church announcements system, event system,

daily devotional updates and membership information. The system increases accessibility as it enables

churchgoers, irrespective of location to receive timely information and spiritual offerings, irrespective of their

presence at church. For church leaders and personnel, the application facilitates the sharing of info with minimum

effort, organisation of information and enhanced decision-making since we facilitate better decision-making

from structured data management. The results of evaluation revealed that the system is rated as satisfactory,

regarding functionality, reliability, usability, efficiency, maintainability, portability, and reliability.

These findings demonstrate that the NTCC Church Mobile App effectively solves these challenges and provides

a credible and working digital solution as an administrative and communications tool for the management and

information about the NTCC Church. Taken together, the system not only enhances interaction, accountability,

and efficiency within the NTCC community, but it is also promising toward adoption and ongoing

adoption/upgrading to the rest of NTCC.
