Assignment task:
"ABC Restaurant" Hiring Process
ABC Chinese Restaurant (ABC for short) is an established chain of Food & and Beverage that offers high-quality dining services in Taiwan. ABC has a few branch stores located in different malls in Taipei. ABC has been facing growing customer demand since the local government eased most of the COVID-19 pandemic safe management measures in May 2022. However,its branch stores were facing manpower shortages in daily operations. ABC is also planning to open more branches in Taiwan or even overseas. For restaurants, the employee turnover rate is often high. Thus, ABC has to regularly hire staff in different positions to meet the growing demand and further expansion requirements. Recently, many branch store managers complained that the Human Resources (HR) department was not recruiting enough staff to fill the vacant positions. On 1 Feb 2023, ABC's HR Director - Tong Tong, investigated the matter and appointed you, who is trained in Lean Six Sigma methodology, to lead a Lean Six Sigma project to improve the hiring process by reducing the average lead time taken to hire staff by at least 30% in three months.
Question:
