Furthermore, Walmart has invested in increasing its employee pay and benefits, as well as providing training and development programs for employees to advance in their jobs. This has resulted in improved employee satisfaction and reduced turnover, which has benefited the company's bottom line.

To handle these significant changes, Walmart has employed a systematic change management strategy that involves including workers in the process, providing them with necessary tools and training, maintaining open communication, and regularly assessing the effectiveness of these changes.

Overall, Walmart has been successful in adapting to a rapidly evolving retail landscape by investing in e-commerce, supply chain management, and employee pay. Through their systematic change management strategy, Walmart has been able to promote lasting improvements in the company while effectively managing the challenges that come with change.
