The document lists various types of issues that can occur when developing or using software systems. It categorizes the issues into business logic related, data related, structural issues, generalized PDTs (presumably problem determination techniques), environment related issues, usage related issues. Within each category it provides examples of specific problems such as incorrect pre-conditions, missing events, truncation of data, resource leakage, inappropriate error handling, and violation of pre-conditions.

1. Missing conditions
Incorrect pre-conditions

Missing events
Time consuming Loss of data
Inefficient code Incorrect data migration
