Given the complexity and interdependence of issues, the chapter explains the first reflection was on form, and it was in relation to the framing of the topics, the construct of the messages that are meant to reach out to the human mind and heart, and trigger the right choices in behavior. The second reflection, a much broader one, relates to institutions, since without the right institutional capacity, the post-2015 agenda will not be implemented. In that respect, the function of organizational development (OD) can play a key role in the transformation and strengthening of institutions. Therefore, when invited to share my views about the contributions that industrial and organizational (I-O) psychology, and in particular humanitarian work psychology (HWP), have made to the Millennium Development Goals (MDGs), my response could only be forward-looking. The pioneering efforts and dedication of I-O and humanitarian work psychologists for building leadership and capable institutions is fundamental to 'the what' and 'the how' of the SDGs.
