製品 ライフサイクル Management (PLM) is a distinct business strategy focused on managing the entire lifecycle of a product from its conception, through design and manufacture, to service and disposal. Unlike the marketing-focused PLC model, PLM is an engineering and supply chain-centric approach, often managed with specialized software, that integrates data, processes, business systems, and people across an extended enterprise.
Product Life Cycle Management (PLM) provides the digital backbone for a product’s entire journey. It is not merely a theory but a practical, technology-driven methodology. At its core, PLM systems create a single, authoritative source of truth for all product-related information. This includes computer-aided design (CAD) data, manufacturing instructions (CAM), bills of materials (BOMs), engineering change orders (ECOs), quality specifications, and supplier details. The lifecycle in PLM is typically divided into three main phases: Beginning of Life (BOL), which covers conception, design, and manufacturing; Middle of Life (MOL), which includes service, maintenance, and in-market use; and End of Life (EOL), which deals with retirement, recycling, or disposal. By centralizing this information, PLM facilitates collaboration between disparate teams—such as engineering, marketing, manufacturing, and procurement—often located across the globe. This integration helps to reduce development time, minimize errors, improve quality, and ensure regulatory compliance. For example, if an engineer updates a component design, the PLM system automatically notifies the purchasing department to source the new part and the manufacturing team to update their assembly instructions, creating a seamless digital thread.
PLMの概念は、主にエンジニアリングデータ(主にCADファイル)の管理に焦点を当てていた製品データ管理(PDM)などの初期システムから発展したものです。PLMはこの範囲を拡大し、製品を取り巻くビジネスプロセス全体を網羅するようになりました。その開発は、自動車や航空宇宙といった複雑な製造業のニーズに大きく影響を受けています。これらの業界では、数千もの部品と多数のサプライヤーを完璧に調整する必要があるからです。グローバルサプライチェーンの台頭と製品の複雑化に伴い、PLMは単なるITソリューションではなく、不可欠な戦略ツールとなりました。
