Final answer:
Efficiency, Profit, and Cross-selling are appropriate performance measurement standards for the strategies mentioned.
Step-by-step explanation:
For the first question, measuring the cost of staffing an area in each store for pickup of online purchases can be considered an appropriate performance measurement standard for efficiency. This involves measuring the ability of the store to allocate resources effectively and minimize costs while maintaining a high level of service for online pickups.
For the second question, measuring the change in Walmart.com's profitability during the first three months of implementation can be considered an appropriate performance measurement standard for profit. This involves monitoring the financial performance of the website and assessing its profitability.
For the third question, measuring incremental in-store sales to customers who pick up online purchases in local stores during the first three months of implementation can be considered an appropriate performance measurement standard for cross-selling. This involves tracking the additional sales generated from customers who visit the store to pick up their online purchases.
