Why flow charts?
Review algorithms Fix bugs
Follow complex logic Avoid bugs
Compare functions Find errors
Restructure bad code Add quality
Document programs Save effort
Read strange languages Reuse code

Visustin for code review. Verify program logic with flow charts. Find bugs before the users do. Save costs by fixing bugs earlier than before.

Visustin for debuggers. Can't see the bug? View a flow graph to gain new insight and speed up debugging.

Visustin for software maintenance. Flowchart old functions to understand them before modifications. After writing changes, flowchart the new version to verify the algorithm. Improved quality guarantees happy users.

More uses for flow charts

Convert languages. Converting old code to a new language? Avoid conversion errors. Flowchart both versions to detect any differences.

Extract business rules from legacy code. Flowchart routines to document the rules embedded in them.

Read an unfamiliar language. Visualize program logic even if the code is in a language you don't know well.

Restructure old spaghetti code. Confirm the results with flow charts.

Understand the incomprehensible. View convoluted code in a new light. Gained insight helps you fix old bugs and avoid adding new ones.
