Too little? Or just right? I Executive summary About the research This Economist Intelligence Unit study, commissioned by Wipro, examines how manufacturers now collect, analyse and use the complex, real-time data generated in production processes By far the most important finding is the increased understanding of how to use process data to improve product quality, but manufacturers are also realising gains in reliability, throughput and maintenance practices by tuning into what their production processes are telling them This report, a follow-up to our 2013 omnibus report on data usage, The data directive: How data is driving corporate strategy—and what still lies ahead, is based in part on a survey of 50 C-suite and senior factory executives from North America (50%) and Europe (50%) from companies that produce a broad range of industrial goods These include electronics (12%), machinery (12%), chemicals and gases (12%), vehicle parts (10%), rubber or plastics (10%) and more Respondents are from intermediate to very large organisations; 32% have global revenues in excess of US$5bn, 32% have revenues of between US$1bn and US$5bn and 36% have revenues of US$500m-$1bn To complement the survey, the EIU conducted in-depth interviews with senior manufacturing executives and academics, as well as related additional research The report was written by Steven Weiner and edited by David Line Our thanks are due to all survey participants and interviewees for their time and insights Interviewees (listed alphabetically by organisation) included: • Peter Zornio, chief strategic officer, Emerson Process Management • Stephan Biller, chief manufacturing scientist, GE Global Research • Joe ElBehairy, vice president, engineering, quality and product strategy, Meritor • Kent Potts, manager of industrialisation, Meritor • Daniel W Apley, professor, industrial engineering and management sciences, Northwestern University • Shiyu Zhou, professor, Department of Industrial Engineering, University of Wisconsin-Madison Respondents by job title Respondent companies by revenue (% respondents) (% respondents) Chief operating officer Other “C-suite” role 14% Head of plant/ factory 10% 34% 12% Chief financial officer US$5bn to US$20bn Chief, supply chain management 20% 10% 16% 4% Chief safety officer Chief technology officer Chief quality officer 36% 6% 2% Chief strategy officer US$500m to US$1bn US$20bn or more 4% © The Economist Intelligence Unit Limited 2014 32% US$1bn to US$5bn Manufacturing and the data conundrum: Too much? Too little? Or just right? Key findings from the survey include: l Manufacturers have significantly ramped up their shop floor data collection Some 86% of survey respondents report major increases in the amount of production and quality-control data stored for analysis over the past two years But it hasn’t been easy— only 14% of those surveyed report no problems managing the data glut from real-time production sensors and associated reporting and analytical models l A minority of manufacturers has an advanced data-management strategy Fewer than half of respondents (42%) have what they consider to be a well-defined data-management strategy A further 44% say they understand why shop floor data is valuable and, consequently, are putting in place resources to realise that value There is no doubting its importance, though: every single manufacturer surveyed reports that data collection is a priority concern for their business l Manufacturers find it difficult to integrate data from diverse sources—and to find the skilled personnel to analyse it Difficulty integrating data from multiple sources and formats is the most commonly cited problem in managing greater volumes of data, picked by 35% of respondents—no surprise, given the age of most manufacturing plants and that technology is transitory while infrastructure is durable Companies also find that because of the speed of data-technology advancement they often lack the internal expertise necessary to maximize the benefits of collected information (cited by 33%) l While data collection from monitoring is common, data analysis to predict issues or solve problems is less so While almost all manufacturers find it normal to monitor production processes—for example, 90% or more say their companies have mature data analysis capabilities for such essentials as asset and facility management, safety, process design and supply chain management—less than half have in place predictive data analytics, and less than 40% use data analytics to find solutions to production problems l Data is delivering stellar quality and production-efficiency gains… Using insights gathered from productiondata analysis, two-thirds of companies report annual savings of 10% or more in terms of the cost of quality (that is, net losses incurred due to defects) and production efficiencies, and about one-third say their savings on both measures have been in the range of 11% to 25% This may explain why more than threequarters of respondents identify aggressive data programmes as an important way to boost efficiency and lower costs l …but collecting data doesn’t automatically yield benefits Despite many manufacturers reporting impressive savings from data analysis, 62% are not sure they have been able to keep up with the large volumes of data they collect, and just 50% are sure they can generate useful insights from it, as it comes from too many sources and in a variety of formats and speeds © The Economist Intelligence Unit Limited 2014 Manufacturing and the data conundrum: Too much? Too little? Or just right? II Ready or not, here it comes Manufacturers have used data to measure production since at least 3000 BC, when the oldest discovered cuneiform tablets were marked with pictographic words and numbers All it took was a reed or stick to mark damp clay, and the number of sheep, bags of grain or output of spears was readable, but only to the literate overseer Today’s “integrated operations go above and beyond what has been the traditional realm of process control ” Peter Zornio, chief strategic officer, Emerson Process Management Similarly, today’s industrial data, displayed on computer screens, is understandable and useful only to the trained overseer But there is far more of it, and it is available instantly, so that as issues arise process adjustments can be made quickly In today’s ideal digitally networked production environment, complex data can be used far more easily than ever to improve product quality, boost throughput, improve shop floor reliability, enhance safety and predict maintenance requirements, eliminating unscheduled downtime That is the ideal, at any rate In the past decade, as more manufacturers have implemented a broader array of digital controls—in the process linking together production machinery that used to operate independently—it has become an appealing vision of what making things might actually become everywhere “Today’s integrated operations go above and beyond what has been the traditional realm of process control,” says Peter Zornio, chief strategic officer of Emerson Process Management, a unit of St Louis, Illinois-based Emerson Electric Company “We think there are three big ideas at the heart of © The Economist Intelligence Unit Limited 2014 it The first is pervasive sensing You can get more and more data points than ever before “Second, integrated operations means multiple disciplines can analyse and discuss data from the plant together, not just one discipline at a time And third is the realm of big data and equally big analytics.” Stephan Biller, chief manufacturing scientist for GE Global Research—a group responsible, among other things, for finding ways to make General Electric’s 400 factories as efficient as possible—says the latest iteration of thinking there is called the “brilliant factory.” The brilliant factory idea works together with the industrial internet and software development that GE calls “Predictivity,” mirroring what theorists believe can be a manufacturing world so all-knowing that it routinely predicts production and product problems and solves them, too “It’s the entire digital thread from engineering and design, to manufacturing engineering, the factory and our suppliers,” says Dr Biller of the GE factory “What’s new is envisioning the feedback loop from the factory in real time, through factory engineering and from the service shops The amount of data is quite astounding.” In fact, at GE’s new battery production plant in Schenectady, New York, 10,000 variables of data are collected, in some cases every 250 milliseconds “We now have an infrastructure in the plant, data highways, that match what we have in the public Internet,” says Dr Biller Manufacturing and the data conundrum: Too much? Too little? Or just right? The allure of this vision is pervasive In a survey of manufacturers conducted by The Economist Intelligence Unit for this paper, 86% say that during the last two years they have significantly increased the amount of production and qualitycontrol data stored for analysis Nearly twothirds say they use sensor-generated data from networked machines—an essential element of the integrated factory—and 20% say they plan to use data from networked production machinery (Figure 1) Equally telling, two-thirds of those surveyed say they also use sensor-generated data from external sources, off their shop floor, for comparison purposes—a move into the more complex and analytically difficult world now generally called “big data” But not everything is settled when it comes to collection and use of digitised data Most factories are decades old and predate in their design any consideration of this type of technology The most recently completed complex greenfield oil refinery in the US began operations in 1977, for example Despite the decades of post-World War II quality improvement programs—such as the teachings of statistical process control guru W Edwards Deming, the scholarship of Joseph Juran, Japanese kaizen process improvement teams, Six Sigma programmes, the Toyota Way and Lean Figure Manifold data sources What sources of data are used by your company to lower the cost of quality and improve manufacturing efficiency?

Too little? Or just right? Manufacturing—tens of thousands of factories in North America and Europe are light years removed from advanced, cutting-edge digital processes systems (88%), accounting and financial data (88%), pre-existing supply chain management systems (86%) and after-sales failure data (82%; Figure 1) Most of these plants installed control systems along the way, many of them proprietary systems that have been locally customised and continue to operate—producing, perhaps, batch reports on operations at the end of the day “There is an enormous amount of data, and it’s a challenge to figure out how to integrate it,” says Daniel W Apley, professor of industrial engineering and management sciences at Northwestern University in Evanston, Illinois “What you would like to use it for is to identify root causes of quality problems and product variation People have been talking about this for decades But the truth is, there are still many open research challenges and no real established methodology that can be used to trace quality problems back to the root causes when there are thousands of upstream process variables that are potential root causes When there are thousands of variables, you typically need data for hundreds of thousands, or millions of parts in order to find meaningful statistical associations between problems and root causes.” “Migrations from systems of this nature are not for the faint of heart,” notes a senior executive in the control systems industry He tells the story of one large factory, with annual revenue of US$500m, where production is controlled by orders written on coloured pieces of paper, one colour for each day of the week If every workstation in the plant is using the same colour, the process is in sync It is therefore no surprise, in this environment, that only 14% of surveyed companies say they have experienced no problems as they manage increasing volumes of machine-generated process and quality data Companies wrestle with efficiency and quality-improvement data from so many sources that confusion and applesto-oranges comparisons are easily made The number-one source of data, used by 96% of surveyed companies, is old-fashioned customer feedback, followed by process historian systems (90%), existing enterprise resource planning © The Economist Intelligence Unit Limited 2014 As GE’s Dr Biller says, “When you think about all the tasks that people have to do—the maintenance system, scheduling, material handling, incoming material, the machines themselves and their error codes, how much material is in each of the buffers, does the part pass or fail—and each plant has 10 to 15 individual systems This is what makes the task somewhat difficult.” Manufacturing and the data conundrum: Too much? Too little? Or just right? III Quality first Respondents to the EIU survey conducted for this report see product quality management as the area in which greater volumes of data are most likely to make the biggest difference Nearly three-quarters (72%) pick this in their top three business areas likely to see gains from more data, a much larger proportion than for any of the other areas and 28 percentage points more than the proportion picking process controls, the number-two area of potential gains (Figure 2) Shiyu Zhou, a professor in the Department of Industrial Engineering at the University of Wisconsin-Madison, says that discussions about the need for better data analytics are “typically reactive” to customer queries or complaints— which often link back to quality issues In fact, he says, it has become easier than ever to hear the voice of the customer because of datadriven product designs that report performance issues automatically to manufacturer service departments Examples, he says, are medical equipment, such as magnetic resonance imagers or CT scanners, or jet aircraft engines that are linked to the Internet and communicate on their own when service is needed Emerging problems, in turn, lead to an enhanced need to boost analytic capacity linked directly to shop floor production processes The machines themselves, in other words, feed the need for process data, leading to installation of more linked machines, and more actionable data in the factory In this view, products that ask for service are like the razor blade, which by steadily growing duller creates the need for more razor blades, and a strategy for making them At Meritor, a maker of drivetrains, axles brakes and other commercial vehicle components, customers tend to focus on one metric—the number of rejected parts per million (PPM)—to evaluate suppliers “When you take into account high-level manufacturing processes—we casting, forgings, stampings, machining, heat treating and assembly—and every truck buyer wants to have the truck the way they want it with specific transmission, axles, and brakes—the variations are in the thousands,” says Joe ElBehairy, Meritor’s vice president for engineering, quality and product strategy What’s more, truck demand can swing wildly in volume, which stresses manufacturing systems, where long and stable production runs most often reduce product variation To respond, Meritor has as much as quintupled the amount of data it collects at its 28 manufacturing plants Meritor began to track defect rates not just by part, but also by individual production operations It also decided to differentiate between reject PPM of products shipped to customers and supplier PPM, which takes into account quality levels from component suppliers In 2013, Meritor’s reject rate was 139 PPM During the first quarter of 2014, with more plants working to improve the traceability of production issues, the rate fell to 67 One plant, producing an entirely new type of air brake, achieved perfection—zero PPM (see case study on page 9) © The Economist Intelligence Unit Limited 2014 Manufacturing and the data conundrum: Too much? Too little? Or just right? Figure Where data can make the difference In which of the following areas you see greater volumes of data yielding the biggest gains? Select the top three (% respondents) 72 Product quality management 44 Process controls 42 Operations management 36 Process design and improvements Predictive maintenance/asset management 30 Supply chain management/sourcing 30 20 Safety & facility management Throughput improvement Targeted capital spending gather “dataFirstandyounetwork it Then you give the people in the plant the ability to operate the system using the data You need to go through the steps rather slowly so that people in the plant understand what we’re trying to do, and so that we can work with them as a collaborator ” Stephan Biller, chief manufacturing scientist for GE Global Research 12 10 “A key element is that we realise, as a company, that quality is valuable to our customers,” says Mr ElBehairy “Some of the principles we applied are not new or earth-shattering, but we’ve been able to apply them to the complexity that we provide in our products.” With the proper analysis of complex production data potentially yielding such dramatic gains in quality and efficiency, it is perhaps no surprise that the rush to collect it still outpaces planning to use it Indeed, just 42% of companies responding to the EIU survey say they have a well-defined data management strategy, although a slightly larger proportion (44%) say they understand the value of shop floor data and are working to capture that value This is despite the fact that all realise the paramount importance of data: every single company surveyed places a priority on data collection GE’s Dr Biller emphasises that an important part of any change in data strategy, and consequent © The Economist Intelligence Unit Limited 2014 alterations to production processes, is careful and considered planning “It’s a step process,” he says “First you gather data and network it Then you give the people in the plant the ability to operate the system using the data You need to go through the steps rather slowly so that people in the plant understand what we’re trying to do, and so that we can work with them as a collaborator Most of the time, the people in the plant know far more about it than you do.” Equally important to realising value from this kind of initiative, says the senior executive from the control systems industry, is absolute commitment from senior management, especially the CEO, to building an integrated data process “You can put in all the components to make it work, the computers and software, but if you don’t have leadership skills and trust, it can lead to failure no matter what system you have,” he says “Having commitment from the CEO is an absolute prerequisite.” Manufacturing and the data conundrum: Too much? Too little? Or just right? Case study: Meritor: Towards data-driven production perfection Like most manufacturers, Meritor, of Michigan, has been on a long and determined drive to improve processes and products at its 28 factories in a dozen countries The company makes drivetrain, braking and other components for trucks, trailers, off-highway, defence and speciality vehicles The latest iteration of company strategy, dubbed M2016, made operational excellence a renewed priority “We adopted as our top metric reject parts per million [PPM],” says Joe ElBehairy, vice president for engineering, quality and product strategy In 2013, companywide this figure was 139 reject PPM With a goal of lowering that to 75 PPM by 2016, Meritor has turned, in part, to carefully heeded, real-time shop floor data “Our data collection is an order of magnitude larger than it was several years ago,” says Mr ElBehairy “Some of it is related to safety, but a lot of our data gathering is related to traceability.” If something goes wrong, Meritor wants to know where and why it happened “And it’s not just collecting data, but realtime acting on that data,” says Kent Potts, industrialisation manager and leader of a quality improvement push at Meritor’s factory in York, South Carolina At York, three workstations assemble calipers for Meritor’s EX+ air disc brake from start to finish More than 40 steps are required for the basic brake, but that’s only the beginning of the product’s complexity Originally launched with 14 different specifications of weight, stopping power, pads, packaging and the like, EX+ assembly ballooned to 169 specifications after sales volume rose sharply following a contract award two years ago A major customer wanted the brakes, but insisted that rejects had to be 10 PPM or less To comply, the York plant added sensors, monitoring gear, a programmable controller system and its own custom programming Employees were trained on an error-proofing system that verifies that the correct parts and processes are applied for each brake Bar codes are used to keep track of parts, and Meritor devised a system called “fit to light”, in which a computer keeps track of the assembly steps for each brake and turns on lights over the correct bin for the next component Reach for the wrong component, and a red light flashes Meritor used tools that communicate with the programmable controllers and socket trays so that the tools could be used for multiple assembly operations and brake specifications The programmable controllers verify that the correct socket and torque gun recipe is used for each assembly process; each piece receives the correct customised treatment “Additionally, process data are stored in our manufacturing genealogy database for each air disc brake that’s assembled The data includes the brake serial number, who assembled it, the component parts installed and process data such as fastener torques,” says Mr Potts The result of this application of real-time networked data to improve shop floor processes has been better than any manufacturer usually expects During the year from March 2013 to March 2014, the York factory had a zero defect rate No product rejects Error-free production also permitted improvement of the on-time delivery rate to 98%—the best of any Meritor plant Techniques like these and tighter attention to quality lowered the company’s overall reject PPM in the first quarter of 2014 to 67, below the 2016 goal Now, the goal is to sustain the progress © The Economist Intelligence Unit Limited 2014 Manufacturing and the data conundrum: Too much? Too little? Or just right? Although state-of-the-art digital systems can predict problems and suggest solutions in advance of actual need, more than half of manufacturers aren’t confident that their analytical skills are up to the task Just 22% of surveyed companies have predictive analytical capabilities for production throughput, for example; just 16% have mature analytical capacity to generate potential solutions In terms of functions, the highest levels of predictive capability are found in supply chain management (44%) and safety and facility management (48%) Mature analytical capabilities to prescribe solutions are most prevalent for asset maintenance (38%) and product quality management (38%) Of course, when evaluating the current state of manufacturing’s digital readiness, two additional issues must be considered First, not all factories actually need the most advanced possible integrated, real-time data “If you operate a smaller factory, and you have a supervisor who can see where everything is, you don’t need all that much data to run it efficiently,” says Dr Biller “If I have a plant that can already run at optimal efficiency, I don’t want to implement sophisticated technology 14 © The Economist Intelligence Unit Limited 2014 because there is no return on investment from it Once you ‘lean out’ a plant and make every process as simple as possible you don’t want to automate it.” Second, even the most sophisticated, integrated digital system is of limited use if companies don’t ask the right questions about their processes or quality issues Data collection and analysis return rewards only when root causes of issues are addressed, rather than just symptoms of those issues One practice used in Six Sigma quality-improvement systems is to repeatedly use the question “Why?” until the root cause is identified For example: A door hinge isn’t working as it should Why? Because it is slightly too large for the fitting Why? Is it because the wrong materials have been used to make it, leading to slight deformations of the part? Are processes slightly maladjusted, leading to hinges of the wrong size? Is the part designed the way it should have been? “Why” questions apply equally to the use of shop-floor data analytics “You must ask the right question to arrive at the right answer,” the old adage goes, and nothing about the modern digital world has changed the truth of this Manufacturing and the data conundrum: Too much? Too little? Or just right? VI The plentiful returns of data success After all is said and done, it turns out that coordinated digital control systems can and produce insights that are extremely valuable results nonetheless indicate that the most dataadept companies are also the most profitable In the survey, manufacturing companies with average earnings growth of 10% or more over the past three years are more likely to have a welldefined data management strategy than those who experienced slower or no earnings growth (59% vs 10%) They are more likely to find ways to improve efficiency and lower the cost of quality (45% vs 25%) They are also less likely to lack staff with sufficient data-analysis capabilities to meet their needs (21% vs 50%; Figure 6) Two-thirds of companies say data from the shop floor have realised savings or gains of more than 10% annually in both new production efficiencies and the cost of quality Some 34% of those surveyed have generated annual savings of more than 25% annually in the cost of quality; the same proportion report 25% or better efficiency improvements annually (Figure 5) Although the results should be interpreted with caution given the sample size—and the fact that correlation does not prove causation—the survey Although the potential for improvement varies widely by facility, Dr Biller says that Figure Savings from data To what extent have insights from shop floor/machine-generated data delivered gains in the following areas?

Ten percent is a pretty conservative number for that ” Stephan Biller, chief manufacturing scientist, GE Global Research 16 21 Routinely analyse data to find ways to improve efficiency and lower cost of quality optimising factory systems provides substantial opportunities “If you look at the supply chain and driving out excess inventory, we talk about savings of perhaps 6% to 20%; we think 10% is actually a conservative number for those implementations,” he says “At GE, where we carry US$15bn in inventory, a 10% saving can be huge How about optimising scheduling to improve throughput? Ten percent is a pretty conservative number for that, and that means you can save in plant and equipment investment because we don’t have to buy additional machines Machine optimisation can produce gains of 20% The benefits can be huge.” Current gains also involve more than money or ROI that justifies the necessary investments in sensors, RFID and bar code equipment, computers, software, training, process realignment, improved production machinery and continual product improvements Evangelists for widely integrated production systems believe a new industrial revolution is in process Fully 50% of surveyed companies agree with the statement: “A rigorous and advanced data analysis capability can be a differentiator for our © The Economist Intelligence Unit Limited 2014 Lack key staff with skills to analyse data company.” This marks an important attitudinal step for manufacturing companies into realtime controls and rapid responses to production variations “Ultimately, the goals of decades of work on inspection and quality control boil down to understanding variation,” says Professor Apley “Perfect manufacturing hypothetically produces the same part, identically, with no variations What we see now is that huge amounts of data are collected, but largely underutilised But data analytics is a new and rapidly expanding area that has great potential for helping to understand variation.” “Think of the manufacturing revolution that’s happening,” says Dr Biller “Yes, we want to make all of our factories more agile, but the great part of this is that we’re building an ecosystem that allows people all over the world to innovate We’re all working on how we can turn that into traditional manufacturing, and then traditional manufacturing into smart manufacturing “We have every science and engineering discipline working for GE in research Of course, Manufacturing and the data conundrum: Too much? Too little? Or just right? smaller manufacturers can’t that But remember, 80% of our parts are designed and made by suppliers We want them and all the links to be part of this digital thread.” Case study: GE’s factory built to produce data The General Electric factory in Schenectady, New York, was built, on one level, to make the company’s new-technology Durathon battery But for the GE Global Research arm, the factory’s most important product is data GE has packed more than 10,000 sensors into the US$170m plant All of them are linked into the most tightly integrated digital control and information systems of any of the company’s 400 global factories The sensors monitor performance indicators for every manufacturing process, building information such as energy use, temperatures and humidity, and even extend to the rooftop weather station If something goes wrong, the sensors, using wi-fi links to staff members wielding hand-held computers, send alerts, and can, if necessary, send text messages to plant employees at home The plant, which began battery production in July 2012, is the test bed and most pronounced expression of GE’s research into ways to create and use the emerging industrial Internet— called by some the “Internet of things”—to build what the company calls the “Brilliant Factory” “This plant has one of the most advanced implementations of our process suite from GE Intelligent Platforms,” GE’s process controls business, says Stephan Biller, chief manufacturing scientist for GE Global Research of nearby Niskayuna, New York “Initially we used the data to improve our own processes What input parameters we have to change? If a battery fails, was it the humidity of that particular process, or the temperature, or operators who we didn’t train well enough? All of this was useful in improving the process.” With precise manufacturing parameters set for the Durathon—which stores and produces electric power on demand using a sodiumnickel chemical process—GE has begun to use the geyser of data to improve efficiency and throughput “The questions now are how we improve costs and get more out of that factory?” says Dr Biller “The key is to think of the entire system, not just parts of it, and by doing this, you can reach an optimal state I don’t want to optimise each individual machine by itself, but as part of a whole system This permits me to find the bottlenecks That’s not a trivial task, and it’s systems thinking that gives you the gains.” © The Economist Intelligence Unit Limited 2014 17 Manufacturing and the data conundrum: Too much? Too little? Or just right? VII Conclusion What these findings mean for manufacturers large and small? Several conclusions seem apparent Firstly, as the science-fiction novelist William Gibson noted, the future has already arrived— it’s just not evenly distributed This is as true of manufacturing as any other field At the cutting edge are companies that operate with complete transparency from end to end of their design, supply, production, shipping and quality control processes They typically have a good grip, through sensors, RFID tags, bar codes and other devices, on how things are going in their factories They can electronically send precise adjustments to production gear and workstations They can measure quickly whether a part isn’t performing as it should They can schedule supplies and shipments accurately and respond to problems effectively Small variations at one part of their data chain don’t produce major surprises elsewhere because their systems, integrated and networked, see the potential impact and fix it GE and others imagine a perfect factory that will never stop producing, ever, because every potential variable is monitored and adjusted and every product is exactly what it should be However, the reality is that very few of today’s aggressive, heads-up manufacturers are close to this vision yet This is partly because the process of integrating data systems and analysis into manufacturing is far from simple In this arena, one size definitely does not fit all In fact 18 © The Economist Intelligence Unit Limited 2014 there really is no standard approach other than to match a company’s appetite for change In addition, the transition is rarely straightforward because most factories are not new and many may not be ideal environments for complex data collection and analysis Older machinery, computer systems that don’t provide real-time data or that are incompatible with others in a production process, and time-honoured production habits clash with the promise of efficiency and quality improvements from the digital world Secondly, the research shows that once manufacturers have decided to implement analytical models they need to think carefully about how data needs to be stored, processed and used Volumes of data have become so large that some companies aren’t certain where to store it all Many still don’t know how to use the information, or even how to formulate production questions that fit the capacity of sensors and software to provide answers Many lack the resources, and probably the trained personnel, to look at much more than monitoring of simply networked shop-floor data Companies that now use multiple separate types of monitoring—with each machine or portion of the production process isolated digitally from the others— won’t find it easy to create such networks But it is worth the try, and in this technological environment, with relatively inexpensive wireless data collection commonplace, the financial commitment is manageable Manufacturing and the data conundrum: Too much? Too little? Or just right? Thirdly, customers will increasingly see the digitised processing, collection and analysis of complex data by manufacturers as a guarantor of quality—over and above traditional accreditations This will become another means of differentiation among peers; companies that lag in this area may find themselves compelled by competition to ramp up their complex data analysis capabilities Finally, the research has shown that the embrace of shop-floor data even on a relatively small scale can be beneficial for even the smallest of producers By monitoring production machinery and processes, efficiencies can be gained and product quality is likely to improve Therefore the question for manufacturing is not whether advanced, integrated, systemic data capabilities are beneficial or the pathway to greater productivity and operations excellence— certainly, they are, and in many cases, the gains from adoption of the latest digital control techniques can be substantial The real issue is how manufacturers can make this vision of the future a reality today © The Economist Intelligence Unit Limited 2014 19 Manufacturing and the data conundrum: Too much?
