Takshshila, the owner of Sandwichworkz, a trendy restaurant in Ahmedabad, India, is worried about the diminishing profitability of her restaurant. Recent promotional offers have increased the footfall, but not profitability. To address this issue, she knew she had to optimize and redesign their menu. She also realizes that to properly address this issue, they would beed to take into account factors such as popularity of each menu item and their per unit profitability. She contacts Nick, a restaurant consultant who further dwells into calculating the costs involved in making each item, to determine the per unit profitability. He proposed plotting the popularity vs. popularity graph (as per Kasavana Smith model) and making qyadrant specific re-enginering decisions. Post his analysis using this menu re-engineering tool, he calls Takshshila with his recommendations. During the call, they come across a new costing methodology which may affect his recommendations. Which methodology should Nick use? Should Takshshila invest in capturing data for the new methodology?
