Final answer:
The most suitable software development approach for implementing the functionality would be Agile methodology. Agile allows for flexibility, frequent communication, and iterative development, ensuring customer needs are met effectively.
Step-by-step explanation:
The most suitable software development approach for implementing the functionality of allowing customers to submit cases and see a dashboard of case resolution history would be Agile methodology. Agile methodology is an iterative approach that allows for flexibility and frequent communication between the development team and stakeholders. This approach is well-suited for projects where requirements may change or evolve over time, which is often the case with customer-facing applications.
In an Agile development process, the team can prioritize features based on customer needs and deliver them in small increments known as sprints. This allows for faster feedback and ensures that the customer's requirements are met effectively. With Agile, Universal Containers can continuously improve and enhance the functionality based on customer feedback and changing needs.
In addition to Agile methodology, the use of Git version control would be beneficial for managing the development and collaboration of the software. Git allows multiple developers to work on the code concurrently, tracks changes, and provides version control and branching capabilities. This ensures that changes can be tracked, conflicts can be resolved, and rollbacks can be made if necessary.
