What is an Information Flow Diagram used for?

• To design an algorithm for performing a process.

• To design a system by breaking our system down into a series of smaller steps.

• To understand how our system works from the perspective of the physical components.

• To analyse information flow in a business to identify bottlenecks and where improvements can be made.

What type of data is best used in tables?

Choose two options.

• Written information.

• Numerical data.

• When presenting information to a large group.

• Where precise values are needed.

What is the benefit of presenting data as written information?

• It allows us to explain ideas in depth.

• It helps when designing a system.

• It’s particularly useful when precise values are needed.

• It requires less time to interpret.
