Guidelines for Preventing and Suppressing Corruption from Procurement and Government Supplies Management Using Public Sector Participation

Abstract

This study develops a Participation-by-Design + Transparency-by-Design framework to prevent and combat corruption in public procurement by integrating citizen participation with usable open data and service-level agreement (SLA)–linked monitoring. A mixed-methods design was employed: a quantitative survey of n=178 respondents (sample size determined by the Taro Yamane formula, e = 0.05) was integrated with qualitative evidence from in-depth interviews, focus groups, analyses of contract datasets and complaints, and a 100-day pilot case study in the “spare parts and components” category of an aviation wing (including Aircraft-on-Ground, AOG situations). Pilot measures included appointing a “data host,” creating a structured parts catalog, opening public Q&A/market sounding, deploying independent observers at technical decision points, and enforcing SLAs for document disclosure and complaint handling.

Findings indicate strong civic/social readiness and recognition of the benefits of open scrutiny, yet long-term system-wide participation is constrained by three structural barriers: (1) high participation costs and limited support mechanisms for citizen monitor networks; (2) technical capacity gaps (reading TOR/reference prices, applying OCDS, red-flag analytics, and e-procurement/audit trails); and (3) centralized, internally focused regulations that leave access-to-information, social-witness, and whistleblower protections unclear. Analysis under the Civic-Embedded Participatory Procurement Integrity Model (CE-PPIM) and procedural justice shows that procedural clarity and institutional trust critically shape citizens’ willingness to monitor and report across the procurement cycle.

To make CE-PPIM operational end-to-end, minimal enabling alignment is required: recognition of citizen monitors’ status/rights, guaranteed access to information, and enforceable SLAs. Outputs should feed a real-time public dashboard and be tracked via a Procurement Legal Acceptance Index (PLAI). The framework aims to close corruption loopholes, reduce information/power asymmetries, and strengthen transparency and shared accountability over the long term.
