12. The Quest for Response Time
Why is Response Time Important?
• Failure to meet service level agreements (SLA)
– Due to long response time
• Customer churns
– Competitive products offer better response time
• Decreased user productivity and decreased customer
satisfaction
– Unhappy customers
• Loss of revenue and decreased profitability
– Effect of lost business and opportunities
