{Reference Type}: Journal Article {Title}: The varied perspectives of organisational effectiveness: What's at stake for early childhood development programmes in Rwanda? {Author}: McMahan LD;Sprague C; {Journal}: Glob Public Health {Volume}: 19 {Issue}: 1 {Year}: 2024 01 {Factor}: 3.356 {DOI}: 10.1080/17441692.2024.2377280 {Abstract}: Within global health and development, dissatisfaction with nongovernmental organisations' effectiveness (NGOs) is an increasingly pervasive aspect of programming. Today, the international community no longer accepts that NGOs are doing what they claim. This change in expectations has emphasised the importance of measuring organisational effectiveness for improved health and development impact. Using New Institutionalism as a theoretical framework, we investigated how institutional norms and expectations influence the adoption of structures and processes by NGOs, and Early Childhood Development (ECD) programming effectiveness in Rwanda - since little research connects these concepts. We employed qualitative methods: 45 in-depth interviews and 6 focus group discussions. Findings revealed a misalignment of 'organizational effectiveness' across scales, from global to local. Findings stress that, effectiveness, though an expectation of the institutional environment, may not be a valid construct for NGOs, generating implications for ECD programming. Findings also indicate measurement of global health interventions generally and the notion of effectiveness specifically can yield adverse implications for ECD programming. These findings are relevant for researchers and practitioners trying to better understand organisational effectiveness for ECD programmes because they suggest that effectiveness is socially constructed and measured differently across the different scales.
