Dear [Manager's Name],

I hope this email finds you well. As the sales staff of KOPIKO, I am writing to report on the sales performance of our boba coffee product, which was introduced three months ago.

Unfortunately, we have not seen the sales figures that we had hoped for with this product. As a result, our team has been brainstorming to identify the possible reasons behind this issue. We have used a fishbone diagram to analyze the problem and have identified several possible factors that may have contributed to the poor sales.

Please find attached the fishbone chart that we have created as a result of our brainstorming activity. As you can see, we have identified several areas that require further investigation, such as product quality, marketing strategies, and target market selection.

We believe that by addressing these issues, we can improve the sales performance of our boba coffee product. We are committed to working closely with our team and management to develop an action plan that will help us overcome the challenges we are facing.

Thank you for your attention to this matter, and we look forward to your feedback on our findings.

Sincerely,

[Your Name]
