* Question
Information system development methodology is a branch of discipline that studies the law of information system development. What is the main content of its research?
* Answer
Information system development methodology is a discipline that studies the principles and
processes involved in developing information systems. The primary research areas of this field
include the following:
1. Development Process and Life Cycle
– System Development Life Cycle (SDLC): Studies the complete lifecycle of an information
system, from requirements analysis, design, development, testing, implementation, to
maintenance, and defines the tasks, goals, and deliverables at each stage.
– Process Models: Explores various development process models like Waterfall, Incremental,
Iterative, and Agile, and examines their suitability for different development environments and
their strengths and weaknesses.
2. Development Methods and Techniques
– Requirements Analysis: Focuses on how to gather, organize, and formalize the system
requirements from users and business needs, ensuring that the developed system meets actual
demands.
– System Design Methods: Studies techniques for system architecture, data modeling,
functional design, and user interface design to build efficient and scalable systems.
– Software Development Techniques: Investigates various programming languages, frameworks,
tools, and technologies to efficiently code, test, and deploy information systems.
3. Project Management and Quality Control
– Project Management: Researches effective project planning, risk management, resource
allocation, and scheduling to ensure the timely and budgeted delivery of information systems.
– Quality Assurance: Examines standards and methods for quality control in system
development, including testing strategies, code reviews, continuous integration, and release
management, to ensure reliability and stability.
4. System Integration and Maintenance
– System Integration: Studies how to integrate different subsystems or external systems into one
cohesive information system, ensuring compatibility and interoperability between systems.
– Maintenance and Upgrades: Explores post-deployment maintenance strategies, fault
management, and methods for system updates and upgrades to ensure long-term operational
sustainability.
5. Development Tools and Automation
– Development Toolchains: Investigates the use of Integrated Development Environments (IDEs),
version control systems, automated testing tools, and continuous integration tools to improve
development efficiency and collaboration.
– Automation in Development: Explores how automation tools (e.g., DevOps) can streamline
deployment, testing, monitoring, and maintenance to reduce human error and speed up the
development process.
6. Team Collaboration and Communication
– Collaboration Methods: Studies different ways of organizing team collaboration (e.g., Agile,
Scrum, Kanban) to reduce bottlenecks and improve team efficiency through effective
communication.
– Communication Tools and Techniques: Researches communication strategies and collaboration
tools (e.g., Jira, Trello) to enhance interaction between development teams, clients, and
stakeholders.
7. Information System Security
– Security Development: Studies how to integrate security into the system development process
and investigates methods to prevent vulnerabilities and protect data privacy through encryption,
authentication, and authorization mechanisms.
– Risk Assessment and Management: Researches how to assess security risks in information
systems and design preventive measures to address potential threats.
8. Agile and Rapid Development Methods
– Agile Development: Investigates how agile methodologies can deliver small, iterative releases
and respond to user feedback and requirement changes quickly.
– DevOps: Studies the integration of development and operations, focusing on how automation,
continuous integration, and continuous delivery can enhance efficiency and collaboration
between teams.
9. User Experience and Usability
– User Experience Design: Examines how to optimize system usability through human-computer
interaction, interface design, and usability testing to ensure the system is user-friendly and
intuitive.
– Feedback Loop: Studies how to integrate user feedback into the development cycle to
continuously improve system functionality and interfaces.
The main goal of research in information system development methodology is to explore and
establish effective development practices and best practices to address the complexity, change,
and risks inherent in information system development, ultimately improving system quality,
reliability, and user satisfaction.
