Examples of financial information system development include creating financial reporting systems, developing customer relationship management (CRM) systems, and creating payment processing platforms.
Best practices of information system development
- Establish a Clear Project Vision: Before starting the system development process, the project manager should establish a clear vision of the system requirements and objectives. This will help ensure that everyone involved in the project is on the same page and working towards the same goal.
- Define the Project Scope: It is important to define the scope of the project early on to ensure that the project’s goals and objectives are achievable. Defining the scope should include determining the features, timeline, budget, and resources required to complete the project.
- Develop a Detailed Project Plan: After the project scope has been established, the project manager should develop a detailed project plan. The plan should include all of the tasks, timeline, budget, and resources needed to complete the project.
- Secure Resources: It is important to secure all necessary resources prior to beginning the system development process. This includes personnel, hardware, software, and tools.
- Monitor Project Progress: The project manager should monitor the project progress throughout the system development process. This includes tracking progress, budget, and resources to ensure that the project remains on track.
- Manage Risks: It is important to identify and manage risks associated with the project. The project manager should identify any potential risks and develop a plan to mitigate them.
- Test and Validate System: After the system is developed, it should be tested and validated to ensure that it meets the requirements and objectives established in the project plan.
- Implement System: After the system has been tested and validated, it should be implemented in the organization. This includes training personnel and documenting system procedures.
- Monitor System Performance: After the system is implemented, the project manager should monitor the system performance to ensure that the system is meeting the established objectives.
