Rolling out the aircraft manufacturer's future star was a marvel of PLM implementation. But what's the point if suppliers aren't kept in the loop?

The Boeing Company's 787 Dreamliner was supposed to be a marvel of industrial planning and design.


It is one of the first airliners to be completely digitally designed using PLM (product lifecycle management) software, and the first-ever virtual rollout of an aircraft. Using Dassault Systems PLM software, Boeing used exact -D models of parts and assembly tooling to plan and layout its production lines—a process that would massively reduce rework on the 787 and dramatically increase time to market, the company said.

But on Oct. 10, before the first planes could even be built, Boeing announced a six-month delay in the initial deliveries of the 787 Dreamliner—from May to December 2008—citing supply shortages, particularly with obtaining composite materials.

Industry insiders believe Boeing's PLM implementation had little to do with the Dreamliner's delayed delivery. Suppliers came up short, out of sequence and/or delivered unfinished parts. But the situation begs the question: What good is PLM if it can't account for the supply chain outside your control? In other words, when will the promise of PLM really be fulfilled?

The promise of PLM software, while understood by vendors, has yet to be fulfilled by users, according to ysts.

"We're still seeing a very high fragmentation on how PLM is used, even though PLM vendors understand the vision," said IDC research yst Joe Barkai. "Just the other day I had a discussion with Dassault's CEO. He absolutely understands the vision of PLM, but [he doesn't] want to be too innovative and create an environment that is not compatible to today's manufacturing, which is more fractured."

Supply by design

Dubbed by IDC's Barkai "Supply by Design" the concept is to push PLM processes out to suppliers as a way to collaborate a design concept along the supply chain.

"Thinking about design for the supply chain goes far beyond just having a database for suppliers. It really is the need to understand a supplier's capabilities, strategy and how that impacts design and vice versa," said Barkai.

"So while Boeing has a very robust design and practice on simulation, they failed on design for the supply chain. Where they are in the process they should not be surprised by suppliers not being able to design [composite materials] on time. I don't think it's the tool. It's how you implement the tool in your process. Boeing sort of missed it."

Some vendors—namely Oracle and SAP—are working to complete the loop between supplier, engineering and manufacturing by coupling PLM software with ERP (enterprise resource planning) and SCM (supply chain planning) software. In May Oracle acquired PLM software developer Agile for $495 million. SAP too has been developing PLM software for a several years.

According to Oracle vice president of SCM Jon Chorley, to really work effectively PLM software has to touch just about every system in a company and along the supply chain—financials, ERP, SCM, SRM (supplier relationship management), CRM (customer relationship management)—and essentially reshape the way customers view product-centric processes.

"Not that you have to duplicate those processes, but you have to access and rephrase them with a product-oriented perspective," said Chorley, in a May interview with eWEEK. But influencing processes beyond the engineering department has been a tough nut to crack.

And some ysts are not convinced that business application's entrée into the PLM stack is the solution—at least not for a while. "Oracle and SAP still look at everything from the BOM [bill of materials]," said Barkai. "Dassault looks at it from the product lifecycle management position. So while Oracle and SAP will have some impact on the market, the future of PLM—the real PLM—is still with PLM [vendors]," where Dassault and UGS lead.

Define requirements early

When Boeing announced that it would delay the initial deliveries of the Dreamliner, industry watchers immediately looked for comparisons between Boeing's Dassault system and that of its major rival, Airbus, which ran into major delivery delays and cost overruns with its Airbus A 80 because of PLM system incompatibilities.

The company's various manufacturing facilities across Europe were using different versions of Dassault's PLM software, which in turn caused errors in engineering specifications when documents were exchanged between systems.

"The types of issues—incompatibility of different versions of Dassault's software in France, Germany and other regions—could have been overcome with good governance between design and manufacturing," said Gartner research yst Marc Halpern. "In the case of Boeing, I don't think that's the situation. Were there problems with PLM? Yes and no."

Halpern said that PLM is not just about the supply chain, it's about guiding a product through the life cycle—being able to capture and reuse the data, information and knowledge associated with the product—and being able to communicate and collaborate with that knowledge.

When he looked at the issues with Boeing's Dreamliner, Halpern said that if there was any place the system didn't work, it was in defining requirements with suppliers.

"When I look at what [is being said] about the Boeing situation—that there were components missing on the inside [at the Dreamliner's unveiling this summer], that work was not done by major partners before major pieces of the structure arrived in Everett—to me that is key. Some of the work done initially with suppliers is defining requirements. Frankly, if anything was broken, that's where it was broken."威海男科医院哪家好
