Chief of Staff (COS) Chapter

The Chief of Staff chapter demonstrates an organizational commitment towards cross-functional management, strategic and people’s risk management through the role of the Chief of Staff.

The Chief of Staff Chapter is the first of its kind to be set up in RIMAS.

The activities of the chapter will be organizing workshops, seminars to promote the role of the Chief of Staff, the concept of cross-functional management, reputation risk management, corporate governance, risk management assessment, responsibility, stewardship, and leadership among our members in the association.

A role that is commonly identified with the armed forces, it is now a worldwide trend for organizations, from private companies to education institutions, to want a Chief of Staff.  Many top firms and startups hire Chief of Staff, and this role has served to mitigate the risk of unchecked decision-making by power executives in the organization. The Chief of Staff step up and challenge such executive’s decisions and to question their judgment.

There is a bright future for risk management practitioners in the role of a Chief of Staff as such role and the knowledge of team management and people’s management strategies become increasingly recognized throughout the business community.
