Software development has been a troubling since it first started. There are seven chronic problems that have plagued it from the beginning:

• Incomplete and ambiguous user requirements that grow by >2% per month.
• Major cost and schedule overruns for large applications > 35% higher than planned.
• Low defect removal efficiency (DRE) < 85% on large systems.
• Cancelled projects that are not completed: > 30% above 10,000 function points.
• Poor quality and low reliability after the software is delivered: > 5 bugs per FP.
• Breach of contract litigation against software outsource vendors.
• Expensive maintenance and enhancement costs after delivery.
