This chapter examines how zakat institutions in emerging Muslim-majority contexts are organized and how they can be redesigned as justice-embedded service ecosystems. Zakat is both worship and mandated redistribution, administered through the office of the amil, yet many institutions have drifted toward an accountability-first posture in which intake is structured around documentary compliance, donor reporting, and audit defensibility. This calibration produces systemic justice effects: urgent relief is delayed, dignity is eroded as applicants are processed as procedural risk, and ownership (tamlīk) is not always made explicit at disbursement. The costs are borne primarily by mustahik, urgent applicants, and frontline amil, while institutional risk is contained for leadership, donors, and regulators. Methodologically, the chapter applies Soft Systems Methodology (SSM) and Critical Systems Heuristics (CSH) as an integrated systems-thinking intervention. SSM models zakat delivery as a multi-actor service system and contrasts the existing coordination logic with a justice-embedded alternative, while CSH surfaces boundary judgments by distinguishing those involved in setting rules from those affected by their consequences. Building on Service-Dominant Logic, we conceptualize zakat institutions as service ecosystems coordinated by institutional arrangements, not merely financial channels. We then specify an operational redesign framework: urgent triage with post-hoc verification, proportional proof tiers, explicit tamlīk at handover, accessible grievance and reversal, and routine boundary review as governance. These arrangements aim to preserve fiduciary accountability while aligning delivery with maqāṣid commitments to justice, harm prevention, dignity, and secure ownership.
