In defiance of conventional wisdom about public sector inertia, government institutions rose to the occasion and delivered digital solutions under inflexible, seemingly unrealistic deadlines. Seeking to build much-needed knowledge on successful important, urgent, and unexpected development efforts (do-or-die projects), we conducted a multiple case study of Norwegian public institutions and found consistent patterns credited for their successes. These relate to 1) antecedent capabilities for collaboration, use of expertise, and interdisciplinary problem-solving; 2) characteristics of the orders for the effort including specificity of goals, importance, deadline, and tie-in with societal mission; 3) emergent development practices that empowered a core team to make decisions, benefit from organizational support, and integrate effectively with diverse stakeholders; and 4) outcomes that reinforced the practices, such as success, pride in work, transparency, and continuous capability development. Findings support and enrich existing research on do-or-die projects\ as a distinct phenomenon of relevance both for non-urgent and urgent contexts. They also demonstrate organizational resilience and robustness in dealing with crises. Implications are outlined for diverse fields of agile practices and principles, public sector interaction, goal-setting leadership, and project studies}, year = {2025}, journal = {Journal of Systems and Software}, publisher = {Elsevier}, }
