the context of Lewin’s model, management homework help

This is my assignment. I chose Walmart as my organization. I only need help with ONE BULLETIN, (**Establish how progress will be measured, 100 words.)

Consider an existing organization you are familiar with, such as an employer, or a company for which you would like to work that operates under a traditional management model. The company’s new CEO is looking to grow the company into a sustainable organization. In her initial evaluation, the CEO realizes that the traditional management approach is not compatible with being sustainable and wants to explore integrating a Corporate Social Responsibility program as an initial step to becoming a sustainable organization.

Create a 1,400-word change management brief or report.

Explain how change management, in the context of Lewin’s model, can help the organization become a socially-responsible organization.

Apply Lewin’s model and outline the following:

• Define the project goals in the context of change management.
• Propose an action plan for creating change.
• Establish how progress will be measured. (This is the part I need help with, 100 words.)
• Determine how performance will be validated.

Include a peer reviewed reference.
