Your resume is your first impression to potential employers, so you want to make sure your change management certification is visible and relevant. You can include it in several places, such as your headline or summary statement, where you can mention it along with your job title, skills, or value proposition. For example, "Certified Change Management Professional with 10 years of experience in leading complex transformations." Additionally, you should add it to your education or credentials section, including the name of the certification, the issuing organization, the date of completion, and any renewal or expiration date. As for your work experience or achievements section, you can highlight how you applied your change management skills and knowledge to deliver successful outcomes. You can also use quantifiable metrics, such as numbers, percentages, or awards, to demonstrate your impact. For example, "Led a cross-functional team of 15 to implement a new CRM system, resulting in a 25% increase in customer satisfaction and a 10% reduction in costs."
