A customer service team at a software company has been experiencing a decline in customer satisfaction scores over the past quarter. To address this issue, the team decides to implement a continuous improvement strategy. They analyze customer feedback and identify that response times to inquiries are significantly longer than industry standards. The team sets a goal to reduce average response time from 48 hours to 24 hours over the next three months. If they plan to achieve this reduction through weekly incremental improvements, what should be their target average response time reduction per week to meet their goal?
