What are six root causes of poor software quality?

These are the causes

• Inadequate training of managers and staff
• Inadequate defect and cost measurement
• Excessive schedule pressure
• Insufficient defect removal
• High complexity levels
• Ambiguous and creeping requirements and design (feature race & gimmicks)

• Inadequate training of managers and staff

When training is not as the managers and staff needed then software may have lack of quality

• Inadequate defect and cost measurement

If defect and cost measurement is not according to the needs

• Excessive schedule pressure

If there is pressure for delivery of the software in short time.

• Insufficient defect removal

When defects are not fixed properly

• High complexity levels

When software is very complex then misunderstanding is one cause for the poor quality

• Ambiguous and creeping requirements and design

When there is ambiguity in requirements and also in design of the software
