Given today's analytical tools and Internet technology, spreading quality and process information throughout an enterprise has never been easier. Nor has it ever been so important: The growth of supply chain management, quality initiatives such as Six Sigma and ever-tightening customer specifications and expectations mean that continuous process monitoring and improvement is everyone's responsibility. With the right tools in place, anyone--from finance to sales to shipping--can look at control charts and other graphs with the click of a mouse.

But it's still a hard sell, isn't it? Driving process intelligence throughout the enterprise can be harder than pushing a string. However, before we look at the obstacles in more detail, let's consider how a successful process-intelligent enterprise should operate.

The process-intelligent enterprise

Process literacy means generating and efficiently distributing process information to people who will use it throughout the enterprise to improve the company's bottom line.

A process-intelligent enterprise:

Knows its processes. The process is flowcharted, and critical parameters and monitoring points are identified.

Knows how to measure and monitor critical process points. It must capture measurements with minimal interruption to normal productive workflow: Measurement devices and systems are in place, operator workflow and interface are optimized, and data are collected without interrupting the operator's primary job of running the process.

Is set up to store and retrieve data efficiently. The database is organized to handle process data, application software is in place to simplify access and retrieval of process data, and data can be delivered in useful reports and charts via intranet, Internet or other means to all who need it.

In a process-intelligent enterprise, process information isn't only for the plant floor, lab or engineering department. It also lends itself to sales, supply-chain management, investor relations, regulatory compliance and any other department that can make the enterprise more competitive and productive. For example:

Sales uses process capability information to price products, win contracts and conduct favorable contract negotiations.

Supply-chain management uses quality data both to prevent and gain an early response to supply-chain incidents.

Investor relations uses process information to show analysts how the enterprise prevents supply-chain incidents.

Regulatory compliance uses process information to generate required reports.

Lab, engineering and plant management all use process data for continuous process improvement and to ensure that products are produced within specifications.

In all these situations, employees have easy access to up-to-date, and often real-time, process information. In each case, the information is tailored to the level of what the person needs to know. For example, it's not reasonable to expect salespeople to understand the intricacies of process capability calculations, but if they have a general understanding of Cpk and control charts, they should have access to data in that format. Likewise, a senior manager doesn't need real-time process data, but he or she does need process information in the form of key performance indicators, similar to the type of data delivered in typical business analytics systems. And, of course, engineering and process control people need it all: KPIs for a quick look, control charts and other types of data graphics, and access to the actual data as needed.

Obstacles to enterprisewide process intelligence

A number of obstacles can impede enterprisewide process intelligence. These include:

Fear of exposure. For some plant operators and managers, sharing process information is the business equivalent to that nightmare of finding oneself stark naked in a crowded public setting. The very idea of making a process available to other departments, suppliers and--worst of all--customers gives them heartburn.

"It would be impossible to share our process data with nonprocess people," observes one plant manager in the food-processing industry. "They'd get freaked out over what looks like under-roasted product, when in fact it just means we need to rerun it through the roaster, which we do all the time. The phone would be ringing off the wall."

A quality department can play a big--and in many cases expanded--role in alleviating fear-based objections by ensuring that those who will be looking at process data have enough process literacy to understand what they're looking at. Along with the actual data, process and quality education should be spread throughout the enterprise.

It's also important for people to realize that sharing process intelligence isn't a matter of "if" but "when." And this sharing isn't restricted to people in-house, either. Customers increasingly demand it, and the sooner your organization figures out how to live with that, the more competitive it will be.

In the semiconductor industry, for example, some companies offer customers complete access to real-time process information via Web-enabled technologies. Customers can view process and quality data at several key production points, check scrap rates and see where their order is on the production line--all without intervention or interpretation by the process owners. Contrary to the latter's expectations, phone lines aren't jammed by hysterical customers. In fact, customers who are more informed about the process are more likely to be understanding and help to resolve process-related problems.

Why are these companies willing to show all? Because it gives them competitive advantage. Chances are your customers are already beginning to think in these terms. Hold back out of fear and they might just run right over you. That's an argument that can convince anyone.

Management doesn't care. A process-intelligent enterprise requires a corporate culture in which process improvement is a well-established precept. Acting alone, the quality department can't make this happen; it needs one or more champions in management.

The key to gaining a management champion is proving return on investment (i.e., demonstrating how people can use process intelligence to improve the bottom line).

Continuous process improvement is still a good argument, especially citing specific examples of how reducing scrap and cycle time can add to the bottom line. However, there's a lot more you could say. One manufacturing company gained substantial leverage in negotiating contracts by teaching its salespeople about process capability. Using control charts and other tools, the sales team was able to show that the company's manufacturing process was highly capable of producing within the customer's specifications. The competition either couldn't or wouldn't do this.

That same sales team was able to negotiate a very favorable contract with a customer whose written specs were originally outside the manufacturer's process capability. The team explored the specs with the customer, and together they discovered that the specs had been written off the cuff by an engineer and weren't all that critical to the functioning of the product. They negotiated new specs that worked for both the customer and the manufacturer's process capability.

Another convincing ROI argument is how quality information can help prevent supply-chain incidents. A recent study, "What Is Supply Chain Management Worth?" by Vinod Singahl and Kevin Hendricks, (IIE Solutions, February 2001) shows that supply-chain incidents pose one of the greatest threats to a company's stock price. If your supply-chain manager uses quality and process information as an early-warning system to ward off such incidents, improvement to the bottom line as well as the stock price could potentially be huge.

We already have process intelligence. Many people in both IT and management assume that because some enterprisewide systems have quality or SPC modules, they therefore have all the process intelligence they need.

The truth is, the larger the scope of the enterprisewide system, the less process intelligence is probably built into it. Frequently, these big systems have no direct connection with the process. Rather, they depend on intermediate layers and use derivative results.

Most of these systems can produce low-level charts, but SPC and/or quality processes remain a secondary issue, usually just a token effort to meet the checklist on a product brochure. Remember that developers of these big systems take on a huge design task. They almost never have deep or specific expertise in quality and SPC, nor should they.

Recognizing this, some of the big-system vendors are partnering with SPC software firms that have the specific expertise to build a module that provides useful process information. If process information in your enterprise will be spread via one of these systems, make sure that the SPC module is up to the job. Otherwise, the process information it generates won't be useful enough to convince anyone to use it.

Process intelligence is too hard for nonprocess people. Nonsense. With minimal training, anyone can learn to read a control chart. The real difficulty lies in choosing the right data and chart to show those nonprocess employees what they need to know.

That's where you come in.

The more you communicate process intelligence, the bigger your burden to present the information at the right level of complexity to those who use it. Simple KPIs may be fine for some; others will need process capability information, control charts, box plots and other tools.

The quality department is the logical place to make those types of decisions and to ensure that the process data are valid and verified. For most enterprises, this will be a natural expansion of the quality department's responsibilities and one that ties it directly to critical company decisions.

Specialized SPC software is too expensive and difficult to implement. The fact is, specialized SPC software is available at a fraction--less than a few percent--of the millions of dollars most companies spend on IT for enterprise resource planning and manufacturing execution systems. If you're currently using Excel or some other solution that's not SPC-specific for analyzing process information, management might be persuaded to write the check for upgrading after hearing the arguments in favor of enterprisewide intelligence. Compare the cost of the software against the savings you can achieve, the losses you can avoid or the sales you can win with it. Convince and enlist your sales and supply-chain people to help.

As far as implementation is concerned, SPC software packages that connect easily with any standard database are available and, without too much IT support, can be configured to send process intelligence throughout the enterprise via corporate intranet.

Keep in mind that your SPC software should be:

Easy to use and configure

Able to pull data from multiple databases

Equipped with easy-to-read and -compare graphics

Easy to install

Technically capable of providing useful process information as needed throughout the enterprise

Is a process-intelligent enterprise truly possible?

Yes, it is. Some companies--notably in the semiconductor, automotive and aerospace industries--have faced and overcome most of the challenges described in this article. These companies share some common conditions:

They need to drive process intelligence throughout the organization in order to survive. Process improvement and intelligence are major factors in how well they compete in the marketplace.

Supply-chain management is so critical that quality-related supply chain events pose a threat to the organization's overall bottom line and/or stock price.

Upper management creates a corporate culture in which process literacy and process improvement can thrive, and also creates a strong "pull" for people at all levels to use quality and process information.

They invest in the IT infrastructure needed to collect, analyze and deliver process information to those who need it. They're also willing to invest in the training needed to help employees gain process literacy.

If your company shares these same conditions, it might be time to consider establishing a process-intelligence system throughout your enterprise. Don't hesitate to begin with smaller goals to achieve this greater one. Make friends with your salespeople. Start talking about what process literacy can do for their contract negotiations. Educate them and encourage them to talk to their managers. Build a few success stories with proven ROIs and then continue from there. Before long, you'll be walking through the cafeteria and hearing words such as "Cpk," "capability" and "control limits." Then you'll know you're on your way to spreading process literacy.
