Data is an essential part of every PLM implementation. It all starts from data – design, engineering, manufacturing, supply chain, support, etc. Enterprise systems are fragmented and representing individual silos of enterprise organization. To manage product data located in multiple enterprise data silos is a challenge for every PLM implementation.
To “demolish enterprise data silos” is a popular topic in PLM strategies and deployments. The idea of having one single point of truth is always in mind of PLM developers. Some of my latest notes about that here – PLM One Big Silo.
MCADCafe article – Developing Better Products is a “Piece of Cake” by Scott Reedy also speaks about how PLM implementation can help to aggregate all product development information scattered in multiple places into single PLM system. The picture from the article presents the problem:
The following passage is the most important, in my view:
Without a PLM system, companies often end up with disconnected silos of information. These silos inhibit the ability to control the entire product record and employees waste unnecessary time searching for the correct revision of the product design. As companies outsource design or manufacturing, it becomes even harder to ensure the right configuration of the product is leveraged by external partners.
Whether your company makes medical devices, industrial equipment, laptops, cell phones or other consumer products – PLM provides a secure, centralized database to manage the entire product record into a “Single Record of the Truth”… With a centralized product record, it is easy to propose and submit changes to the product design, track quality issues and collaborate with your internal teams and supply-chain partners.
The strategy of “single record of truth” is a centerpiece of each PLM implementation. However, here is the thing… if you look on the picture above you can certainly see some key enterprise systems – ERP, CRM, MES, Project and program management, etc. PLM system can contain scattered data about product design, CAD files, Part data, ECO records, Bill of Materials. However, some of the data will still remain in other systems. Some of the data gets duplicated. This is what happens in real world.
It made me think about 3 important data architecture aspects of every PLM implementation: data management, data reporting and data consistency.
Data management layer is focusing on what system is controlling data and providing master source of information. Data cannot be mastered in multiple places. Implementation needs to organize logical split of information as well as ability to control “data truth”. This is the most fundamental part of data architecture.
Data reporting is focusing how PLM can get data extracted from multiple sources and presented in seamless way to end user. Imagine, you need to provide an “open ECO” report. The information can reside in PLM, ERP and maybe some other sources. To get right data in a right moment of time, can be another problem to resolve.
Last, but not least – data consistency. When data located in multiple places system will rely on so-called “eventual consistency” of information. The system of events and related transactions is keeping data in sync. This is not a trivial process, but many systems are operating in such way. What is important is to have a coordinated data flow between systems supporting eventual consistency and data management and reporting tools.
What is my conclusion? To demolish silos and manage single point of truth is a very good and important strategic message. However, when it comes to nuts and bolts of implementation, an appropriate data architecture must be in place to insure you will have right data at right time. Many PLM implementations are underestimating the complexity of data architecture. It leaves them with marketing slogans, burned budgets and wrong data. Just my thoughts…
Best, Oleg
