Creating project plans to focus product development   总被引:17,自引:0,他引:17  
The long-term competitiveness of most manufacturers depends on their product development capabilities. Yet few companies approach the development process systematically or strategically. They end up with an unruly collection of projects that do not match long-term business objectives and that consume far more development resources than are available. Instead of working on important projects, development engineers spend their time fighting fires. Their productivity sinks, and products are invariably late to market. To attack development malaise and reinvigorate the process, companies should put together an "aggregate project plan." The plan helps managers restructure the development process so they no longer think in terms of individual projects but in terms of the "set" of projects. It is the set, not individual projects, that shapes the creation of a successful product line. The aggregate project plan also helps managers allocate resources, sequence projects, and build critical development capabilities. A central element of the aggregate project plan is the project map. The map categorizes projects into five types: breakthrough, platform, derivative, research and development, and partnerships. Each project type has its own unique characteristics and requires a different amount of development time. Companies should have projects in all categories to ensure a robust development process.  相似文献

With a new product, time is now more valuable than money. The costs of conceiving and designing a product are less important to its ultimate success than timeliness to market. One of the most important ways to speed up product development is through interfunctional teamwork. The "Return Map," developed at Hewlett-Packard, provides a way for people from different functions to triangulate on the product development process as a whole. It graphically represents the contributions of all team members to the moment when a project breaks even. It forces the team to estimate and re-estimate the time it will take to perform critical tasks, so that products can get out fast. It subjects the team to the only discipline that works, namely, self-discipline. The map is, in effect, a graph representing time and money, where the time line is divided into three phases: investigation, development, and manufacturing and sales. Meanwhile, costs are plotted against time--as are revenues when they are realized after manufacturing release. Within these points of reference, four novel metrics emerge: Break-Even-Time, Time-to-Market, Break-Even-After-Release, and the Return Factor. All metrics are estimated at the beginning of a project to determine its feasibility, then they are tracked carefully while the project evolves to determine its success. Missed forecasts are inevitable, but managers who punish employees for missing their marks will only encourage them to estimate conservatively, thus building slack into a system meant to eliminate slack. Estimates are a team responsibility, and deviations provide valuable information that spurs continuous investigation and improvement.  相似文献

Recent theoretical and empirical work indicates that management control systems (MCS) are an important element in enhancing innovation. We extend this research thrust examining the adoption of MCS in product development, arguably one of the business processes where innovation plays a major role. Using a sample of 69 early-stage entrepreneurial companies, data are collected from questionnaires and interviews with each of the CEO, financial officer, and business development managers pertaining to product development MCS. We examine seven different systems: project milestones, reports comparing actual progress to plan, budget for development projects, project selection process, product portfolio roadmap, product concept testing process, and project team composition guidelines. We address three distinct questions: (1) What are the reasons-for-adoption of these systems? The nature of our sample allows us to trace back to the adoption point and develop a set of reasons-for-adoption from the analysis of the data. While MCS fulfill certain roles as described in the literature, these reasons-for-adoption are distinct from these roles. Results indicate that certain events lead managers to adopt these systems and address the challenges that they face. They include contracting and legitimizing the process with external parties and internal reasons-for-adoption such as managers’ background, learning by doing, need to focus the organization, or reaction to problems. (2) Are these reasons-for-adoption associated with differences across companies in the time from their founding date until these systems are adopted (time-to-adoption)? Prior research has looked at the covariance of various organizational variables with this timing; this study goes a step further by looking at the effect of different reasons-for-adoption on this timing. Our evidence finds an association between these two variables. (3) Are these reasons-for-adoption relevant to performance? We find that the reason-for-adoption is associated with the on-time dimension of product development performance.  相似文献

The continued success of technology-based companies depends on their proficiency in creating next-generation products and their derivatives. So getting such products out the door on schedule must be routine for such companies, right? Not quite. The authors recently engaged in a detailed study--in which they had access to sensitive internal information and to candid interviews with people at every level--of 28 next-generation product-development projects in 14 leading high-tech companies. They found that most of the companies were unable to complete such projects on schedule. And the companies also had difficulty developing the derivative products needed to fill the gaps in the market that their next-generation products would create. The problem in every case, the authors discovered, was rooted in the product definition phase. And not coincidentally, the successful companies in the study had all learned how to handle the technical and marketplace uncertainties in their product definition processes. The authors have discerned from the actions of those companies a set of best practices that can measurably improve the definition phase of any company's product-development process. They have grouped the techniques into three categories and carefully lay out the steps that companies need to take as they work through each stage. The best practices revealed here are not a magic formula for rapid, successful new-product definition. But they can help companies capture new markets without major delays. And that is good news for any manager facing the uncertainty that goes with developing products for a global marketplace.  相似文献

Design thinking   总被引:4,自引:0,他引:4  
Brown T 《Harvard business review》2008,86(6):84-92, 141
In the past, design has most often occurred fairly far downstream in the development process and has focused on making new products aesthetically attractive or enhancing brand perception through smart, evocative advertising. Today, as innovation's terrain expands to encompass human-centered processes and services as well as products, companies are asking designers to create ideas rather than to simply dress them up. Brown, the CEO and president of the innovation and design firm IDEO, is a leading proponent of design thinking--a method of meeting people's needs and desires in a technologically feasible and strategically viable way. In this article he offers several intriguing examples of the discipline at work. One involves a collaboration between frontline employees from health care provider Kaiser Permanente and Brown's firm to reengineer nursing-staff shift changes at four Kaiser hospitals. Close observation of actual shift changes, combined with brainstorming and rapid prototyping, produced new procedures and software that radically streamlined information exchange between shifts. The result was more time for nursing, better-informed patient care, and a happier nursing staff. Another involves the Japanese bicycle components manufacturer Shimano, which worked with IDEO to learn why 90% of American adults don't ride bikes. The interdisciplinary project team discovered that intimidating retail experiences, the complexity and cost of sophisticated bikes, and the danger of cycling on heavily trafficked roads had overshadowed people's happy memories of childhood biking. So the team created a brand concept--"Coasting"--to describe a whole new category of biking and developed new in-store retailing strategies, a public relations campaign to identify safe places to cycle, and a reference design to inspire designers at the companies that went on to manufacture Coasting bikes.  相似文献

Companies that introduce new innovations are the most likely to flourish, so they spend billions of dollars making better products. But studies show that new innovations fail at a staggering rate. While many blame these misses on lackluster products, the reality isn't so simple. The goods that consumers dismiss often do offer improvements over existing ones. So why don't people purchase them? And why do companies keep peddling products that buyers are likely to reject? The answer, says the author, can be found in the brain. New products force consumers to change their behavior, and that has a psychological cost. Many products fail because people irrationally over-value the benefits of the goods they own over those they don't possess. Executives, meanwhile, overvalue their own innovations. This leads to a serious clash. Studies show, in fact, that there is a mismatch of nine to one, or 9x, between what innovators think consumers want and what consumers truly desire. Fortunately, companies can overcome this disconnect. To start, they can determine where their products fall in a matrix with four categories: easy sells, sure failures, long hauls, and smash hits. Each has a different ratio of product improvement to change required from the consumer. Once businesses know where their products fit into this grid, they can manage the resistance to change. For some innovations, major behavior change is a given. In those cases, companies can either wait for consumers to warm to the product, make the improvement so great that buyers get past their apprehension, or try to eliminate the incumbent product. Firms can also try to minimize buyer resistance by making products that are compatible with incumbent goods, seeking out those who are not yet users of the existing product, or finding true believers.  相似文献

K M Hudson 《Harvard business review》2001,79(7):45-8, 51-3, 143
You wouldn't think of Brady Corporation as an obvious place in which to find a fun culture. This traditional Midwestern company, a manufacturer of industrial signs and other identification products, didn't even allow employees to have coffee at their desks until 1989. But when Katherine Hudson became CEO in 1994, she and her executive team determined that injecting some fun into the company's serious culture could create positive effects within the organization and contribute to increased performance and sales. In this article, Hudson distills her approach to overhauling Brady's culture into six principles of serious fun: More people than you might think are comfortable having fun at work; used with an awareness of cultural sensitivities, fun and laughter really are well-understood international languages; humor can help companies get through tough times; fun can be embodied in formal programs; spontaneous efforts at humor can also be effective; and encouraging fun should begin at the top. She richly illustrates each principle with examples. At Brady, getting people to loosen up and enjoy themselves has fostered a company esprit de corps and greater team camaraderie. It has started conversations that have sparked innovation, helped to memorably convey corporate messages to employees, and increased productivity by reducing stress, among other benefits. And the company has doubled its sales and almost tripled its net income and market capitalization over the past seven years. Brady's experience suggests that promoting fun within the workplace can lead not only to a robust corporate culture but also to improved business performance.  相似文献

More than 5,000 joint ventures, and many more contractual alliances, have been launched worldwide in the past five years. Companies are realizing that JVs and alliances can be lucrative vehicles for developing new products, moving into new markets, and increasing revenues. The problem is, the success rate for JVs and alliances is on a par with that for mergers and acquisitions--which is to say not very good. The authors, all McKinsey consultants, argue that JV success remains elusive for most companies because they don't pay enough attention to launch planning and execution. Most companies are highly disciplined about integrating the companies they target through M&A, but they rarely commit sufficient resources to launching similarly sized joint ventures or alliances. As a result, the parent companies experience strategic conflicts, governance gridlock, and missed operational synergies. Often, they walk away from the deal. The launch phase begins with the parent companies' signing of a memorandum of understanding and continues through the first 100 days of the JV or alliance's operation. During this period, it's critical for the parents to convene a team dedicated to exposing inherent tensions early. Specifically, the launch team must tackle four basic challenges. First, build and maintain strategic alignment across the separate corporate entities, each of which has its own goals, market pressures, and shareholders. Second, create a shared governance system for the two parent companies. Third, manage the economic interdependencies between the corporate parents and the JV. And fourth, build a cohesive, high-performing organization (the JV or alliance)--not a simple task, since most managers come from, will want to return to, and may even hold simultaneous positions in the parent companies. Using real-world examples, the authors offer their suggestions for meeting these challenges.  相似文献

Stop wasting valuable time   总被引:1,自引:0,他引:1  
Mankins MC 《Harvard business review》2004,82(9):58, 60-5, 136
Companies routinely squander their most precious resource--the time of their top executives. In the typical company, senior executives meet to discuss strategy for only three hours a month. And that time is poorly spent in diffuse discussions never even meant to result in any decision. The price of misused executive time is high. Delayed strategic decisions lead to overlooked waste and high costs, harmful cost reductions, missed new product and business development opportunities, and poor long-term investments. But a few deceptively simple changes in the way top management teams set agendas and structure team meetings can make an enormous difference in their effectiveness. Efficient companies use seven techniques to make the most of the time their top executives spend together. They keep strategy meetings separate from meetings focused on operations. They explore issues through written communications before they meet, so that meeting time is used solely for reaching decisions. In setting agendas, they rank the importance of each item according to its potential to create value for the company. They seek to get issues not only on, but also off, the agenda quickly, keeping to a clear implementation timetable. They make sure they have considered all viable alternatives before deciding a course of action. They use a common language and methodology for reaching decisions. And they insist that, once a decision is made, they stick to it--that there be no more debate or mere grudging compliance. Once leadership teams get the basics right, they can make more fundamental changes in the way they work together. Strategy making can be transformed from a series of fragmented and unproductive events into a streamlined, effective, and continuing management dialogue. In companies that have done this, management meetings aren't a necessary evil; they're a source of real competitive advantage.  相似文献

Sooner or later, most companies can't attain the growth rates expected by their boards and CEOs and demanded by investors. To some extent, such businesses are victims of their own successes. Many were able to sustain high growth rates for a long time because they were in high-growth industries. But once those industries slowed down, the businesses could no longer deliver the performance that investors had come to take for granted. Often, companies have resorted to acquisition, though this strategy has a discouraging track record. Over time, 65% of acquisitions destroy more value than they create. So where does real growth come from? For the past 12 years, the authors have been researching and advising companies on this issue. With the support of researchers at Harvard Business School and Insead, they instituted a project titled "The CEO Agenda and Growth". They identified and approached 24 companies that had achieved significant organic growth and interviewed their CEOs, chief strategists, heads of R&D, CFOs, and top-line managers. They asked, "Where does your growth come from?" and found a consistent pattern in the answers. All the businesses grew by creating new growth platforms (NGPs) on which they could build families of products and services and extend their capabilities into multiple new domains. Identifying NGP opportunities calls for executives to challenge conventional wisdom. In all the companies studied, top management believed that NGP innovation differed significantly from traditional product or service innovation. They had independent, senior-level units with a standing responsibility to create NGPs, and their CEOs spent as much as 50% of their time working with these units. The payoff has been spectacular and lasting. For example, from 1985 to 2004, the medical devices company Medtronic grew revenues at 18% per year, earnings at 20%, and market capitalization at 30%.  相似文献

Turn customer input into innovation   总被引:26,自引:0,他引:26  
It's difficult to find a company these days that doesn't strive to be customer-driven. Too bad, then, that most companies go about the process of listening to customers all wrong--so wrong, in fact, that they undermine innovation and, ultimately, the bottom line. What usually happens is this: Companies ask their customers what they want. Customers offer solutions in the form of products or services. Companies then deliver these tangibles, and customers just don't buy. The reason is simple--customers aren't expert or informed enough to come up with solutions. That's what your R&D team is for. Rather, customers should be asked only for outcomes--what they want a new product or service to do for them. The form the solutions take should be up to you, and you alone. Using Cordis Corporation as an example, this article describes, in fine detail, a series of effective steps for capturing, analyzing, and utilizing customer input. First come indepth interviews, in which a moderator works with customers to deconstruct a process or activity in order to unearth "desired outcomes." Addressing participants' comments one at a time, the moderator rephrases them to be both unambiguous and measurable. Once the interviews are complete, researchers then compile a comprehensive list of outcomes that participants rank in order of importance and degree to which they are satisfied by existing products. Finally, using a simple mathematical formula called the "opportunity calculation," researchers can learn the relative attractiveness of key opportunity areas. These data can be used to uncover opportunities for product development, to properly segment markets, and to conduct competitive analysis.  相似文献

Chinese companies have grown rapidly over the past few decades, and become increasingly global in the process. In the past five years, the aggregate market capitalization of public companies in China increased more than ten‐fold and their revenue from outside China grew 60%. Nevertheless, Chinese companies have financial policies that are notably different from those of their global counterparts in North America and Europe, and that difference could end up limiting their future profitability and growth. In this report, J.P. Morgan's Corporate Finance Advisory team compares the capital structures of large Chinese companies to those of the largest companies in the U.S., the U.K. and Germany. Among the most important findings, Chinese companies have materially more leverage, much greater reliance on bank loans than bonds, and maturities that are almost 80% shorter than those of typical U.S. companies. To bring their balance sheets in line with those of their global peers, Chinese companies are likely to have to raise over 5 trillion yuan (over $750 billion) in equity while also issuing roughly the same amount in bonds. At the same time, in order to attract that capital on economic terms, they will likely need to find ways to increase the profitability of their businesses, whose return on equity is well below international standards. As the authors point out in closing, making such significant changes in financial and operating policies could be challenging for all stakeholders, and cause some potential dislocation in the short run. But however disruptive, such changes are most likely to ensure the ability of Chinese companies to create the most value in the long run.  相似文献

Six Sigma pricing   总被引:1,自引:0,他引:1  
Many companies are now good at managing costs and wringing out manufacturing efficiencies. The TQM movement and the disciplines of Six Sigma have seen to that. But the discipline so often brought to the cost side of the business equation is found far less commonly on the revenue side. The authors describe how a global manufacturer of industrial equipment, which they call Acme Incorporated, recently applied Six Sigma to one major revenue related activity--the price-setting process. It seemed to Acme's executives that pricing closely resembled many manufacturing processes. So, with the help of a Six Sigma black belt from manufacturing, a manager from Acme's pricing division recruited a team to carry out the five Six Sigma steps: Define what constitutes a defect. At Acme, a defect was an item sold at an unauthorized price. Gather data and prepare it for analysis. That involved mapping out the existing pricing-agreement process. Analyze the data. The team identified the ways in which people failed to carry out or assert effective control at each stage. Recommend modifications to the existing process. The team sought to decrease the number of unapproved prices without creating an onerous approval apparatus. Create controls. This step enabled Acme to sustain and extend the improvements in its pricing procedures. As a result of the changes, Acme earned dollar 6 million in additional revenue on one product line alone in the six months following implementation--money that went straight to the bottom line. At the same time, the company removed much of the organizational friction that had long bedeviled its pricing process. Other companies can benefit from Acme's experience as they look for ways to exercise price control without alienating customers.  相似文献

Consider a coffeemaker that offers 12 drink options, a car with more than 700 features on the dashboard, and a mouse pad that's also a clock, calculator, and FM radio. All are examples of "feature bloat", or "featuritis", the result of an almost irresistible temptation to load products with lots of bells and whistles. The problem is that the more features a product boasts, the harder it is to use. Manufacturers that increase a product's capability--the number of useful functions it can perform--at the expense of its usability are exposing their customers to feature fatigue. The authors have conducted three studies to gain a better understanding of how consumers weigh a product's capability relative to its usability. They found that even though consumers know that products with more features are harder to use, they initially choose high-feature models. They also pile on more features when given the chance to customize a product for their needs. Once consumers have actually worked with a product, however, usability starts to matter more to them than capability. For managers in consumer products companies, these findings present a dilemma: Should they maximize initial sales by designing high-feature models, which consumers consistently choose, or should they limit the number of features in order to enhance the lifetime value of their customers? The authors' analytical model guides companies toward a happy middle ground: maximizing the net present value of the typical customer's profit stream. The authors also advise companies to build simpler products, help consumers learn which products suit their needs, develop products that do one thing very well, and design market research in which consumers use actual products or prototypes.  相似文献

The ambidextrous organization   总被引:29,自引:0,他引:29  
Corporate executives must constantly look backward, attending to the products and processes of the past, while also gazing forward, preparing for the innovations that will define the future. This mental balancing act is one of the toughest of all managerial challenges--it requires executives to explore new opportunities even as they work diligently to exploit existing capabilities--and it's no surprise that few companies do it well. But as every businessperson knows, there are companies that do. What's their secret? These organizations separate their new, exploratory units from their traditional, exploitative ones, allowing them to have different processes, structures, and cultures; at the same time, they maintain tight links across units at the senior executive level. Such "ambidextrous organizations," as the authors call them, allow executives to pioneer radical or disruptive innovations while also pursuing incremental gains. Of utmost importance to the ambidextrous organization are ambidextrous managers--executives who have the ability to understand and be sensitive to the needs of very different kinds of businesses. They possess the attributes of rigorous cost cutters and free-thinking entrepreneurs while also maintaining the objectivity required to make difficult trade-offs. Almost every company needs to renew itself through the creation of breakthrough products and processes, but it shouldn't do so at the expense of its traditional business. Building an ambidextrous organization is by no means easy, but the structure itself, combining organizational separation with senior team integration, is not difficult to understand. Given the executive will to make it happen, any company can become ambidextrous.  相似文献

Silo busting: how to execute on the promise of customer focus   总被引:1,自引:0,他引:1  
Gulati R 《Harvard business review》2007,85(5):98-108, 145
For many senior executives, shifting from selling products to selling solutions--packages of products and services--is a priority in today's increasingly commoditized markets. Companies, however, aren't always structured to make that shift. Knowledge and expertise often reside in silos, and many companies have trouble harnessing their resources across those boundaries in a way that customers value and are willing to pay for. Some companies--like GE Healthcare, Best Buy, and commercial real estate provider Jones Lang LaSalle (JLL)--have restructured themselves around customer needs to deliver true solutions. They did so by engaging in four sets of activities: COORDINATION: To deliver customer-focused solutions, three things must occur easily across boundaries: information sharing, division of labor, and decision making. Sometimes this involves replacing traditional silos with customer-focused ones, but more often it entails transcending existing boundaries. JLL has experimented with both approaches. COOPERATION: Customer-centric companies, such as Cisco Systems, develop metrics for customer satisfaction and incentives that reward customer-focused cooperation. Most also shake up the power structure so that people who are closest to customers have the authority to act on their behalf. CAPABILITY: Delivering customer-focused solutions requires some employees to be generalists instead of specialists. They need experience with more than one product or service, a deep knowledge of customer needs, and the ability to traverse internal boundaries. CONNECTION: By combining their offerings with those of a partner, companies can cut costs even as they create higher-value solutions, as Starbucks has found through its diverse partnerships. To stand out in a commoditized market, companies must understand what customers value. Ultimately, some customers may be better off purchasing products and services piecemeal.  相似文献

Developing products on Internet time   总被引:2,自引:0,他引:2  
The rise of the World Wide Web has provided one of the most challenging environments for product development in recent history. The market needs that a product is meant to satisfy and the technologies required to satisfy them can change radically--even as the product is under development. In response to such factors, companies have had to modify the traditional product-development process, in which design implementation begins only once a product's concept has been determined in its entirety. In place of that traditional approach, they have pioneered a flexible product-development process that allows designers to continue to define and shape products even after implementation has begun. This innovation enables Internet companies to incorporate rapidly evolving customer requirements and changing technologies into their designs until the last possible moment before a product is introduced to the market. Flexible product development has been most fully realized in the Internet environment because of the turbulence found there, but the foundations for it exist in a wide range of industries where the need for responsiveness is paramount. When technology, product features, and competitive conditions are predictable or evolve slowly, a traditional development process works well. But when new competitors and technologies appear overnight, when standards and regulations are in flux, and when a company's entire customer base can easily switch to other suppliers, businesses don't need a development process that resists change--they need one that embraces it.  相似文献

More and more, expanding companies are hiring high-functioning groups of people who have been working together effectively within one company and can rapidly come up to speed in a new environment. These lifted-out teams don't need to get acquainted with one another or to establish shared values, mutual accountability, or group norms; their long-standing relationships and trust help them make an impact very quickly. Of course, the process is not without risks: A failed lift out can lead to loss of money, opportunity, credibility, and even native talent. Boris Groysberg and Robin Abrahams studied more than 40 high-profile moves and interviewed team leaders in multiple industries and countries to examine the risks and opportunities that lift outs present. They concluded that, regardless of industry, nationality, or size of the team, a successful lift out unfolds over four consecutive, interdependent stages that must be meticulously managed. In the courtship stage, the hiring company and the leader of the targeted team determine whether the proposed move is, in fact, a good idea, and then define their business goals and discuss strategies. At the same time, the team leader discusses the potential move with the other members of his or her group to assess their level of interest and prepare them for the change. The second stage involves the integration of the team leader with the new company's top leadership. This part of the process ensures the team's access to senior executives-the most important factor in a lift out's success. Operational integration is the focus of the third stage. Ideally, teams will start out working with the same or similar clients, vendors, and industry standards. The fourth stage entails full cultural integration. To succeed, the lifted-out team members must be willing to re-earn credibility by proving their value and winning their new colleagues' trust.  相似文献

Despite companies' almost fanatical worship of innovation, most new products don't generate money. That's because executives don't realize that the approach they take to commercializing a new product is as important as the innovation itself. Different approaches can generate very different levels of profit. Companies tend to favor one of three different innovation approaches, each with its own investment profile, profitability pattern, risk profile, and skill requirements. Most organizations are instinctively integrators: They manage all the steps needed to take a product to market themselves. Organizations can also choose to be orchestrators: They focus on some parts of the commercialization process and depend on partners to manage the rest. And finally, companies can be licensers: They sell or license a new product or idea to another organization that handles the commercialization process. Different innovations require different approaches. Selecting the most suitable approach, the authors' research found, often yields two or three times the profits of the least optimal approach. Yet companies tend to rely only on the mode most familiar to them. Executives would do better to take several different factors into account before deciding which tack to take, including the industry they're trying to enter, the specific characteristics of the innovation, and the risks involved in taking the product to market. By doing so, companies can match the approach to the opportunity and reap the maximum profit. Choosing the wrong approach, like Polaroid did, for example, can lead to the failure of both the product and the company. Optimizing their approaches, as Whirlpool has done, helps ensure that companies' innovations make money.  相似文献
