Study Notes

Iterative Development

One advantage of addressing changes and improvements incrementally is that it reduces the overall cost of incorporating changes.
Increased user satisfaction is a benefit of iterative development because it allows for continuous feedback and early deliveries, leading to a more tailored product.

Project Suitability

Iterative development is particularly useful for projects where the full scope may not be fully understood at the outset.

Stakeholder Benefits

Iterative development provides stakeholders with continuous feedback and early deliveries.

Complex Projects

One benefit of iterative development for complex projects is that it allows for incremental development and testing.

User Satisfaction

One advantage of increased user satisfaction in iterative development is that it leads to a more tailored product.

Information Systems

The first step in building an information system is gathering information.
The stakeholders involved in or affected by an information system include users, developers, and management.
The purpose of gathering information in the context of building an information system is to understand the business needs and requirements.
The main objective of analyzing business processes in the context of building an information system is to identify areas for improvement.
The main purpose of analyzing data in the context of building an information system is to understand the data requirements.
The final step in building an information system is implementing and testing the system.
Functional and non-functional requirements are defined in the context of building an information system.
