ROI Calculation Logic

Assuming this technology reduces communication outage frequency by 10% annually and shortens response time by 20%. For instance, if 50 outages occur annually, with an average response cost (engineer labor, customer support, lost revenue, etc.) of $3,500 (AI est.) per incident, the total annual cost is ~$150K (AI est.). With this technology, the cost could be ~$125K (AI est.), leading to a direct annual cost reduction of ~$25K (AI est.). Including benefits from improved quality and customer retention, an economic impact exceeding ~$150K (AI est.) per year is anticipated.
