Vista Academy is proposing training updates to define excellence in San Diego. The training would focus on minor fixes revealed in the first three rounds, evolving training by incorporating perfect practice, and embedding a Vista culture through practices like setting Aldi-like operating hours. Key aspects would include coupling static training with live store experience, formalizing live store expectations, and addressing training proactively through updates to PIP, produce, and organization training. The proposal aims to benefit the training academy, stores, and continued progress towards the standard of greatness.
