Is MBA a good option for me to put as my program instead of supply chain management?

Yes, given your 56 months of work experience and a bachelor's degree in Organisational Learning and Leadership, an MBA - especially with a concentration in Supply Chain Management (SCM) - is a strong option.

An MBA will give you a broad business foundation (finance, marketing, strategy) while allowing you to specialize in SCM. This is ideal if you aim for senior management or leadership roles that require a wider business perspective.

If you prefer a purely technical and analytical focus on SCM, a Master of Science (MS) in Supply Chain Management is also an option. However, with your experience, an MBA aligns well with career advancement and leadership goals.

Be sure to address your 24 gap years in your application, explaining how you used this time constructively.
