The Data Builds the Products

ITT Fluid Technology has been working on a project to support the global sharing of design, engineering, manufacturing and other product-related information among its various operations. The initiative, part of a wider effort to implement a "design anywhere, build anywhere" capability, should also let the manufacturer sell, service and integrate its parts everywhere, says global products and data manager Ron Watson.

The White Plains, N.Y.-based subsidiary of $4.7 billion engineering conglomerate ITT Industries Inc. is one of many manufacturers turning to product life-cycle management (PLM) tools to improve manufacturing efficiency, product quality and time to market.

The systems let different groups exchange and collaborate on product-related images and data in real time, both internally and with outside suppliers and customers. To do this, the systems must gather and integrate data from sources ranging from design and engineering systems to manufacturing and field operations.

A wide variety of collaborative products fall under the PLM umbrella, including product data management technologies that integrate data from bill of material, computer-aided design (CAD), change management and enterprise resource planning (ERP) systems; configuration management systems that validate product configurations and link product specifications with engineering modules; and maintenance, repair and overhaul modules that link field services systems with change management and engineering.

While the benefits of linking such systems can be enormous, organizations that have launched PLM projects caution others to prepare for process and procedural changes, cultural issues and implementation challenges.

Because PLM systems are cross-functional in scope, installing one is often more difficult than companies anticipate, says Erica Rugullies, an analyst at Giga Information Group Inc. in Cambridge, Mass. The integration work involved in tying together disparate systems is substantial, she says.

"Companies can go about this in a few ways," Rugullies says. "They can look upon this as a huge project that requires extensive integration, software dollars and a number of players in different roles, or they can go after a specific business problem, such as finding a new way to effectively share digital data." But in either case, users should fully understand the issues involved in planning and deploying a PLM system, users and analysts say.

Upfront Issues

First and foremost, PLM products are still maturing, so the risk is that the software won't always live up to expectations. "PLM software can be buggy, it could require extensive programming to deliver the needed functionality, and it may not enable compliance with government requirements," Rugullies says. She recommends conducting a proof of concept before purchasing a PLM tool and budgeting time for troubleshooting and implementing fixes.

In addition, a full-fledged PLM project can be nearly as complex as rolling out an ERP system, so knowing upfront what value you want to get out of it is vital, says Marc Hendrickson, a Detroit Lakes, Minn.-based design documentation manager at Team Industries Inc., a manufacturer of powertrain and chassis components. Only then is it possible to know what information in a product's life cycle needs to be captured, how to manage it and what kind of workflow and decision-making processes need to be implemented. Team Industries uses Parametric Technology Corp.'s (PTC) Pro/Engineer CAD and Pro/Intralink data management software to tie data from its parts-development process to shop-floor data. In doing so, Hendrickson says he hopes to improve quality, parts reuse and time to market.

Setting the right scope is important, says Jim Heppleman, chief technology officer at PTC, a Waltham, Mass.-based vendor of PLM software. For instance, if the business goal is to reduce time to market, the project emphasis should be on enabling capabilities such as rapid digital prototyping and product bill-of-material management, Heppleman says. Similarly, if the goal is to increase product standardization, the focus might be on improving configuration management or on design reuse, he adds.

It also helps to have standard tools and interfaces when creating and sharing a single view of enterprise product data, says ITT's Watson. ITT is linking and integrating product design and engineering data across several manufacturing operations. To facilitate the process, ITT standardized on PTC's Pro/Engineer software for creating product design data and on Pro/Intralink to share data between sites.

Using a common software platform reduces the complex integration and data translation issues that are otherwise involved, he says. Using standardized tools can also result in better design integrity and reuse and lead to better sourcing and material management processes, Watson adds.

Taking Small Bites

When planning a deployment, don't bite off more than you can chew, warns Hendrickson. "In a small organization where resources are limited, it might make the best sense to take a phased approach," he says.

His company adopted a three-phase approach to implementing PLM. In the first phase, he "nailed down" the company's parts-development process in order to determine what type of data he needed to capture and when. (Team Industries has identified 50 separate data points as a result of this exercise.)

Team Industries is now in the second phase: tying the data to information generated on the manufacturing floor. In the third phase, it will integrate that data into the company's manufacturing resource planning system.

Customizing packaged software to fit specific business needs can also be a problem. New Balance Athletic Shoe Inc. in Boston is using PLM products from MatrixOne Inc. in Westford, Mass., to improve the effectiveness of its product development and procurement process and to make collaboration with international partners easier.

But New Balance has had to customize the software "a little more than we wanted to," says Bill Armelin, the shoe company's business systems project leader. For example, some procurement forms that the PLM system generated were different from what internal teams were used to, even though users input the same data. Similarly, what internal design teams refer to as a "specification sheet" appears as a bill of materials function in the PLM suite.

Be prepared to tweak your processes to avoid software customization, says Hendrickson. Team Industries changed its parts-numbering process and revisioning scheme to better use the capabilities of the PLM suite it's rolling out.

Getting users to adopt PLM systems can also be a challenge. "One of the things we noticed is that if you try to do too much right out of the box with a system like this, it is too much of a culture shock," says Tim Bahr, manager of technical development at New Balance.

Getting nonengineering people to use PLM systems can be especially challenging, so it's important to spend time explaining and demonstrating the value a PLM system can bring to the different business units, adds Watson.

His group conducted road shows at several ITT manufacturing facilities to demonstrate the value of the PLM system. But even with those efforts, Watson says that "only a very small percentage of people ... really believe they need this stuff."

Equally important is the need to get user feedback and include that in the requirements-gathering process, says Rugullies. Putting PLM training groups in the middle of the units that are most reluctant to adopt PLM may also pay off, she suggests.

Ultimately, getting PLM right is as much about setting the right expectations as it is about the implementation, says Frank Azzolino, president of Waltham, Mass.-based PLM vendor Eigner. "This is an industry that has historically overpromised but underdelivered," he says.
