I am confusing how to do the bow tie analysis, here is my work about the bow tie analysis. Could you help me check out it is correct or not? If not please help me to fix, Thanks!

According to the annual report of Walmart and Amazon, credit sales accounted for 75% of Walmart's total sales and Amazon's 85%. Due to the impact of COVID-19, some suppliers failed to meet Amazon and Walmart's terms and conditions or their supplier standards. Credit sales and supplier issues are considered A threat to Walmart or Amazon, which is on the left in Bow Tie analysis. Covid-19 causes some customers to lose their ability to earn or some customers to lose their source of income and become unable to repay their debts. On the other hand, suppliers affected by COVID-19 are unable to supply according to the standard, resulting in a short period of shortage of goods. These two events can be considered major events, in the middle of Bow Tie analysis and with serious consequences. As a result, Wal-Mart and Amazon have become less liquid, which means they may not have enough cash flow to support their day-to-day operations.With suppliers less able to supply, Wal-Mart and Amazon may have to face shortages on some items.These consequences are on the right side of the bow tie analysis.
