インドネシアのボトル飲料水工場でDMAICを用い、手作業の運用報告をペーパーレス化した事例研究。事務作業量69.30%減、報告サイクル68.75%短縮、データ検索78.19%短縮、紙消費99.25%減を達成し、紙由来CO2も99.25%削減。DMAICが要件・原因・デジタル機能・ガバナンスを結ぶ socio-technical な枠組みとして有効と示した。
English
A single-case study applied DMAIC to convert manual operational reporting into paperless reporting at an Indonesian bottled-water plant. Administrative workload fell 69.30%, reporting cycle time 68.75%, data-retrieval time 78.19%, and paper consumption/carbon footprint 99.25%, all significant at p<0.001. DMAIC served as a traceable socio-technical architecture linking requirements, root causes, digital features, and governance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の製造業がSSBJ・Scope3対応やGXリーグでの排出削減を進める中、紙・帳票由来の間接排出削減と業務効率を同時に狙うDMAIC型ペーパーレス化は、現場主導のGX実装例として参考になる。ただし炭素削減は紙消費に限定され、Scope1/2/3全体の会計とは切り分けて読む必要がある。
In the global GX context
For global disclosure scholarship, this adds a manufacturing-floor case where process-improvement methodology (DMAIC) doubles as a lightweight decarbonization lever, relevant to Scope 3 paper/procurement accounting and CSRD-style operational data governance. It is a narrow single-site study, so it informs implementation practice more than disclosure standards.
👥 読者別の含意
🔬研究者:DMAICと環境指標を統合した混合研究法の設計例として、介入前後のペア比較と記述指標の区別が参考になる。
🏢実務担当者:紙帳票のデジタル化を業務効率と紙由来排出削減の両立策として検討する際の、実装・ガバナンス手順の参考になる。
🏛政策担当者:中小製造業のデジタル化支援が省資源・間接排出削減に波及する可能性を示す一事例として留意。
📄 Abstract（原文）
Purpose— This study examines how Define-Measure-Analyze-Improve-Control (DMAIC) was used to transform manual operational reporting into paperless reporting at an Indonesian bottled drinking water manufacturing plant and evaluates the associated operational and environmental changes. Method— An applied, participatory embedded mixed-methods single-case design combined eight Voice of Customer interviews, process observation, document review, NVivo 14 coding, root-cause analysis, 30 paired before-after observations, and post-implementation member checking. Paired differences were evaluated using Wilcoxon signed-rank and paired-samples t-tests. Findings— After implementation, administrative workload decreased by 69.30%, reporting cycle time by 68.75%, data-retrieval time by 78.19%, and paper consumption by 99.25%. The estimated paper-related carbon footprint also declined by 99.25%. All five paired comparisons were significant at p < 0.001, while the documentation error rate decreased descriptively from 14.35% to 3.24%. Eight user validators reported an overall mean of 4.63/5.00. Conclusion and Implications—DMAIC provided a traceable socio-technical architecture linking user requirements, baseline evidence, root causes, digital features, governance, and validation. Manufacturers should treat paperless reporting as process redesign supported by clear ownership, infrastructure controls, and continuing performance monitoring. Originality/Value—The study integrates qualitative diagnosis, quantitative before-after evaluation, participatory digital implementation, environmental measurement, and Control-stage governance within one end-to-end reporting intervention, while explicitly distinguishing inferential indicators from descriptive and mathematically derived measures.
