Organizing for sustainability: processes and managerial practices

How does an organization truly make sustainability part of its fabric? The journey from ambitious goals to everyday practice is a complex challenge, a problem of architecture rather than just aspiration. This thesis digs into that challenge by comparing how very different companies in Belgium’s consulting and recruiting sector are fundamentally restructuring themselves for sustainability. One side is Randstad Belgium, A large multinational. Their approach is like engineering a machine. They create specialized roles and formal committees, use a sophisticated global data system, and align everything to meet structured reporting rules. This systematic pathway builds consistency, manages risk, and ensures compliance in a large organization. But the risk is that sustainability can become a technical box-ticking exercise. A glossy report instead of a shared conviction. Onthe other hand, there is EngineerX, a smaller, specialized firm. Here, sustainability is not engineering, but growing. There is no separate department; it is in the founder’s values and through informal networks and everyday project decisions. This organic adaptation pathway feels authentic and is remarkably agile, allowing the firm to pivot and innovate quickly. However, it is fragile, dependent on individual passion, and can struggle to scale or meet complex regulations. This research shows that there is no universal blueprint. The systematic and organic models are not stages of maturity, but distinct and valid pathways, each with its own logic, strengths, and inevitable trade-offs. A multinational imposing agility on its complex struc ture or an SME mimicking the bureaucracy of a global firm are recipes for failure. Instead, success depends on contextual intelligence. A clear assessment of who they are as an orga nization and a deliberate design of the sustainability journey to build their inherent strengths while honestly managing the inherent weaknesses. For leaders, policymakers, and educators, this study provides not a list of best practices, but a powerful diagnostic lens. The central question is no longer simply what to do, but how to design an organization that can do it, in a way that makes sense of its size, culture, and place in the world.
