Integrated Ahp–Ipa For Optimising Execution‑Centre Communication In A Refinery Megaproject

Abstract

Cost and schedule overruns in refinery megaprojects are frequently triggered by information latency and stakeholder misalignment. This study quantitatively assessed the effectiveness of an ad‑hoc Execution Centre Communication (ECC) established for the revitalisation of the Residual Catalytic Cracking (RCC) unit in Balongan, Indonesia. Five experts completed pair‑wise comparison matrices, and their judgements were synthesised through the Analytic Hierarchy Process to derive criterion weights. Subsequently, 53 practitioners evaluated ECC performance via a five‑point Likert survey. The AHP weights were used as importance scores and combined with mean performance ratings in a modified Importance–Performance Analysis. Information Accuracy obtained the highest weight (0.375) yet scored below the performance mean, placing it in the “Concentrate‐Here” quadrant together with Stakeholder Alignment. Recommended quick wins include enforcing a single‑source‑of‑truth dashboard and weekly cross‑function alignment forums. The integrated AHP–IPA framework thus provides a data‑driven roadmap for allocating limited resources to the most influential communication levers.
