Systems Development is the process of creating, designing, deploying, and maintaining an information system. This could include software or a web-based application. The process typically involves various stages such as concept initiation, system analysis, design, coding, testing, deployment, and maintenance. Through this procedure, an efficient and effective system is built to meet the unique needs of a particular business or organization. It’s pivotal in enhancing the operational efficiency for the user by automating or simplifying complex tasks.

Systems Development Examples

1. Developing an Online Shopping Application

The process of systems development can be applied in the creation of an online shopping application for a retail company. In the concept initiation phase, analysts and strategists determine the application’s main functions and features. These could be product listing, shopping cart management, secure payment process, and user account management.

The design phase is next and it aims to create an inviting and easy-to-navigate user interface. Wireframes and prototypes are usually developed at this stage, ensuring that the end product will cater to the end user’s needs.

The coding phase comes next, where developers will work towards building the application based on the specifications laid out in the design phase. They’ll ensure the code is clean and efficient to maintain a high-performing app.

Testing is a critical stage in systems development. Here, the application is put through rigorous test cases to ensure all features work as expected and any bugs are identified and fixed. This stage is essential to confirm the app’s readiness for deployment.

The final step is to deploy the tested application to the public. User feedback may be collected after this step for potential updates or improvements in the maintenance phase, thus the cycle of systems development continues even after the app is made live to public.

2. Customized Business Management Software

In the manufacturing industry, a company may embark on a systems development process to create a tailored business management software. This software could include comprehensive modules for inventory control, order management, production planning, and more. The initiation phase will involve defining these requirements with input from various stakeholders in the organization.

The design phase focuses on designing the software interface and architecture. The interface should be user-friendly, making it easy for employees to navigate. Additionally, the architecture is designed to ensure the system can handle the expected data load and operate efficiently.

During the coding phase, experienced programmers implement the design plan. They write robust and efficient code to ensure the software operates smoothly without glitches and can handle thousands of transactions and large volumes of data. This phase is very critical as it forms the core of the entire system.

In the testing phase, the software is subjected to various test scenarios to uncover potential bugs and make sure it performs as intended in diverse conditions. Different types of testing, like functional testing, system testing, and stress testing, are carried out to ensure comprehensive coverage.

Final deployment involves rolling out the software to the organization for use. After it’s deployed, the software moves into the maintenance phase, which includes software updates, bug fixes, and enhancements based on user feedback. Therefore, the systems development process is a continuous, cyclical one, seeking to always improve and update the software to meet evolving requirements.

3. School Management System

A school may undertake a systems development project to create a comprehensive school management system. This system could handle numerous activities like student enrolment, course management, and report generation. In the initiation phase, the school administration, teachers, and other stakeholders would collaborate to define the functions and features that the management system should possess in order to meet the specific needs of the institution.

The design phase follows, focusing on creating a friendly and efficient layout for the users. This phase is critical as it directly impacts the usability of the system. Both the visual interface and the internal architecture are planned out, taking into consideration how administrators, faculty, students, and parents might interact with the system.

The coding phase involves the development team writing lines of code to convert designs into a functioning software. The main goal here is to create efficient and error-free code to realize the features and functions defined in the earlier phases.

After coding comes the testing phase. This phase is crucial for identifying and resolving any bugs or issues that could prevent the system from performing its intended functions. The test cases could simulate regular use and extreme cases to ensure the system functions well under all conditions.

Lastly, the system is deployed throughout the school for use. After deployment, the system enters the maintenance phase where periodic upgrades, bug fixes, and performance enhancements take place. This helps to ensure that the system continues to meet the needs and expectations of its users, maintaining its efficiency and effectiveness in managing school activities.


In essence, systems development refers to the process of creating and managing the lifecycle of an information system. Whether it’s for an online retail app, a manufacturing management software, or a school administration system, the phases of initiation, design, coding, testing, deployment, and maintenance are critical in building efficient and user-centric digital solutions.

Key Takeaways

  • Systems development process helps in creating, designing, deploying, and maintaining an information system.
  • This procedure can be implemented in different realms like online shopping applications, business management software, and school management systems.
  • The stages of the systems development process often involve initiation, design, coding, testing, deployment, and maintenance.
  • This method ensures the efficiency of the system by catering to the unique needs of a particular organization or business.
  • Even after the system gets deployed, updates or improvements may be made based on user feedback, making the systems development a consistent process.

Related Questions

1. What is the main objective of systems development?

The main objective is to create an efficient and user-friendly system that meets the specific needs of an organization, streamlines operations or tasks, and ultimately contributes to the achievement of the organization’s goals.

2. Who is involved in the systems development process?

There are typically multiple stakeholders involved, including business analysts, system analysts, programmers and coders, quality assurance testers, project managers, and end users or user representatives of the system being developed.

3. Why is the testing phase important in systems development?

The testing phase is vital as it ensures that all functions of the system work as designed and expected. It helps to identify and fix bugs, glitches, and areas of inefficiency. This phase assures the quality of the final product before it’s deployed.

4. Can systems development process be applied to any industry?

Yes, the systems development process can be applied to any industry that requires an information system. Whether it’s retail, manufacturing, education, healthcare, or any other sector, the process can be tailored to fit the specific needs of the organization.

5. What happens during the maintenance phase of systems development?

During the maintenance phase, periodic updates and enhancements are made to the system based on user feedback and technological advances. Issues identified during use are also fixed in this phase, further improving the system’s performance and efficiency.
