Abstract

This paper addressed the problem of high waiting time in a petro-chemical industry in Indonesia. According to Pareto diagram, the procurement process at the industry showed that the number of fast moving item transactions was more than 70% or 19,836 item transactions with 2,524 fast moving material items. The activity of making Purchase Requisition (PR) until the issuance of Purchase Order (PO) for fast moving items required a cycle time of 71.2 days. The highest waste was waiting with a weight of 0.248 and a total of 17 waste items from 27 sub-activities. The average value of sigma for 6 years was 1.79. The application of lean six sigma and MAFMA found that the dominant causes of waste were unfulfilled specified demand and long delivery time. We proposed improvements by enhancing monitoring processes and submitting a contract agreement for the procurement of fast moving spare parts.

Abstract

Increasing business competition necessitates innovative approaches to strategic planning, particularly among small and medium-sized enterprises (SMEs). This study introduces the Collaborative Business Planning (CBP) model, which differs from conventional approaches by embedding collaboration through synergy, transparency, and shared responsibility among business group members. Using a simplified Delphi method, consensus was obtained from experts and practitioners to identify key collaboration factors, design the CBP framework, and validate its structure. The model integrates expert consensus, strategic planning, and financial feasibility analysis to produce a comprehensive planning tool for business groups. Implementation of the CBP model in KUB Mandiri Bersinergi demonstrated substantial improvements in performance and cooperation. Financial assessments revealed a positive Net Present Value (NPV) and an Internal Rate of Return (IRR) exceeding 20 percent, confirming its economic viability. The study contributes a structured framework for strengthening collaboration, enhancing efficiency, and promoting sustainability within SMEs. The CBP model provides both a theoretical and practical foundation for collective business planning, offering strategic guidance for SMEs to manage collaboration effectively and achieve long-term competitive advantage.
