    A BSTRACT

    Recently the hybrid lean-agile manufacturing system has been proposed in order to meet the current automotivemarket winning order criterion of a blend of cost and availability. This study shows how strategically a hybrid lean-agile manufacturing system can be implemented. It shows statistically that almost one third of the variationin successfully dealing with the sources of competitive advantage in automotive sector can be explained byadopting the strategic facet of the hybrid lean-agile manufacturing system. The cost demanded by theimplementation of the hybrid lean-agile manufacturing system can be moderated by the gained benefits of reduced operational cost and reduced time to market.

    I. INTRODUCTION Getting the right product, at the right price, at the right time, in the right place to the consumer is notonly the way to achieve competitive advantage, but is also the key to sustainable success in themanufacturing sector. According to Womack [1,2] significant interest has been shown in recent yearsin the idea of lean manufacturing and the broader concept of the lean enterprise . Yet, the demandin the current automotive market is volatile and the customers requirements for variety are high whichtogether demand for a much higher level of agility. Hence it is not surprising that becomingcompetitive in terms of cost, a lean attribute, can cause the value chain to become threatened interms of availability, an agile attribute. A newer manufacturing approach than the leanmanufacturing to deal with the change in the manufacturing business environment is agilemanufacturing. The concept of agility comprises two main factors which are: (a) responding to changein proper ways and in good time and (b) exploiting changes and taking advantage of them asopportunities [3,4] . Yet, this agile manufacturing approach has exhibited a cost challenge.This research stems from the changes in the manufacturing business environment in the automotivesector that have led to customers requirements of both competitive cost and availability withoutcompromising quality [ 5]. The research method adopted in the present research starts with literaturereview of the manufacturing systems which traditionally exist in automotive industry. From thisliterature review research questions are derived. Answers to some of these research questions areproposed in a form of a research hypothesis. The rest of the research questions are answered from theliterature review. In an endeavour to validate the research hypothesis, both interview with executivesof and review of annual reports of ground vehicle manufacturing companies and Original Equipment

    Manufacturers (OEMs) have been conducted. Since case studies are useful in developing solutions tothe current manufacturing business problems, the General Motors Production System, as a leader in

    automotive sector that has a global corporate strategy, is examined in light of the proposed HLAMS,in order to verify the relevance of the proposed manufacturing system to the real world of theautomotive business.This research paper investigates the implementation of the strategic aspects of the proposed HLAMS.The paper starts with literature review. Research questions are then derived from literature review.Risk management in product design and manufacturing is investigated after that and the presentresearch will identify how HLAMS addresses this aspect. This is followed by presenting the proposedimplementation method of the strategic aspects of the proposed HLAMS. Finally, verification,validation, and the limitations of the proposed manufacturing system will be presented.

    II. L ITERATURE R EVIEW In order to balance the automotive product portfolio, the engineering resources have to be utilized byglobal vehicle platforms by shifting product development and manufacturing programs to low-costmanufacturing bases, such as China, India, Mexico, Brazil, and South Africa [6]. The challenge willbe in building a global engineering network to support vehicle product development andmanufacturing in such multiple regions [7-10]. Therefore, the concept of hybrid lean-agilemanufacturing system (HLAMS) has been proposed recently [11].The rules for competing and surviving in the automotive industry are changing rapidly. Time andknowledge are the essence of winning in the contemporary marketplace [12]. Thus, success in theglobal automotive market is increasingly linked to the enterprises ability to rapidly turninginformation into knowledge. The winners will be extended enterprises with the capability to integrate,optimize, and collaborate across their entire value chain faster, better, and more profitably thananyone else. The winning value-chains will be those that strike a balance between cost andavailability of products and related services in terms of low costs, short product development anddistribution cycles, and smart investments in value-chain business and technology practices. In otherwords, a blend of leanness and agility is expected be a necessity in meeting such contemporarysuccess criteria [11].Value engineering can be implemented in the development of any product, such as a car, to optimizeits value [13]. Some scientists called for what was called leagility or agilean, but what they proposedis to adopt leanness in the upstream of the value chain before the decoupling point and agility in thedownstream of the value chain after the decoupling point [14]. What the HLAMS proposes is amanufacturing system that hybridizes both leanness and agility together in one manufacturingframework to be implemented throughout the value chain [11]. The proposed HLAMS hybridizes thestrategic attributes of both the lean and agile manufacturing systems in order to realize both flexibilityof production equipment, of chaining plants, and of execution of a production order along withresponsiveness to varying customer needs.In the automotive sector, planners have a difficult balancing act. On the one hand, there are benefitsfrom using common vehicle parts. On the other hand, there are more niche demands in the globalmarket. The challenge that faces the entire automotive industry is to balance these two extremes cost-effectively and without compromising quality. This challenge is evident in light of recent and frequent

    safety recalls of millions of vehicles in the automotive sector, even from the lean manufacturingpioneer, Toyota [15]. The current research aims to meet this balancing act by proposing animplementation method to implement the strategic facet of the HLAMS. The implementation of thestrategic facet of the HLAMS aims at striking a balance between the main six competitive dimensionsof manufacturing in the automotive sector, which are quality, delivery reliability, response time, lowcost, customization and product life cycle, in addition to revenue [16]. Research questions can now bederived from this literature review.

    III. R ESEARCH Q UESTIONS AND H YPOTHESIS The research questions have been derived from the literature review. Answers to some of theseresearch questions are proposed in a form of a research hypothesis.

    demand prediction for more than three months; (2) factoring multiple demand scenarios intoproduction planning; (3) decisions about the items of the most unpredictable demand should bepostponed until some market signals such as early sales data become available; (4) for seasonalproducts, making the items of predictable demand in advance in order to reserve greatermanufacturing capacity for making the items of unpredictable demand and shift the production of those items that their demand is relatively unpredictable closer to the selling season [ 22]. The secondof these couple of risks due to market and environmental uncertainty is unsatisfied customers. This isalso an avoidable risk that can be avoided by taking the following measures: (1) conducting customersatisfaction survey; (2) conducting Failure Modes and Effects Analysis (FMEA) [23] ; (3) actingaccordingly on eliminating the causes behind this dissatisfaction.The unavoidable risks happen because of the existence of the four unavoidable uncertainties that areconsumers, competitors, technology, and resources. The consumer uncertainty is a sort of marketuncertainty that results in the risk of the ever increasing demand for short lead time. In order to reduceboth of the level of this uncertainty and its impact, the following measures should be taken: (1)manufacturing should be carried out in the countries in which the cost of manufacturing per unit soldis the cheapest and which are geographically the closest to the location of the market-places of sellingthe product; (2) machine capacity and type of vehicles to be manufactured, e.g. car, bus, or truck,

    should be determined based on a global aggregate forecast of demand based on the expected growthin population in the countries that are the market places of selling the product.The competitor uncertainty is another sort of market uncertainty that results in the risks of the demandfor variety of choices, low prices, and new entrants. The following measures should be taken toreduce both the level of this uncertainty and its impact: (1) implement the agile dimension of theHLAMS in order to deal with the risks of the demand for variety of choices and new entrants; (2)implement the lean dimension of the HLAMS in order to deal with the risk of the demand for lowprices.The third unavoidable uncertainty is the technology uncertainty which is a sort of the technologicaluncertainty. This uncertainty can result in the risk of obsolescence and lack of efficiency and can bedealt with by adopting scalable and upgradeable technology. The fourth unavoidable uncertainty is theresources uncertainty which is a sort of the technological uncertainty. This uncertainty can result in

    the risk of incomplete tasks and consequently long lead time. The following measures should be takenin order to reduce both the level of this uncertainty and its impact: (1) sharing resources throughoutthe entire value chain so that loading gets leveled; (2) having resources of flexible attribute in itsoperating method and in its construction/architecture so that bottlenecks get resolved.The present research proposes a risk management action plan to minimize risk in the product designand manufacturing processes. The proposed risk management action plan consists of the followingthree phases which are (1) before the beginning of the product design process, (2) during the productdesign process, (3) before the beginning of and during the manufacturing process.

    1. Before the beginning of the product design process phase:Conducting Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis for the

    manufacturing enterprise;Establishing strategic partnership with key suppliers, technology providers, and retailers.2. During the product design process phase:

    2.1. Proving value of design concept to customers at the end of each design phase throughmarket research and close-contact with key customers.

    3. Before the beginning of and during the manufacturing process phase:3.1. Conducting FMEA.

    Having investigated this, let us now explore the proposed implementation method of the strategicaspects of the proposed HLAMS.

    V. IMPLEMENTATION OF THE P ROPOSED H YBRID L EAN -AGILEM ANUFACTURING SYSTEM

    The implementation of the strategic facet of the HLAMS consists of a short-term phase and long-termphase. In the short term, the assessment of the current state of the manufacturing system with respectto the HLAMS is implemented, a change plan towards the HLAMS is set, and the Five-S method is

    applied throughout the entire value chain. In the long term, the change plan towards the HLAMS iscarried out and the HLAMS should be fully implemented. A proposed implementation plan of theHLAMS is illustrated in Table 1, and is proposed for each of the cases of either a firm has alreadyestablished its manufacturing business or is going to establish its manufacturing business.For the already established manufacturing firm, the change program is four-fold. At the systemengineering level, requirements are reviewed with the marketing team and key customers in order toeliminate those requirements which are unnecessary and costly. In addition, a product design reviewchecklist is developed and reviewed since most costs are assigned when a product is designed andoften design engineers specify what they are familiar with rather than what is most efficient [24] .Since a manufacturing strategy refers to an approach that starts with corporate, business, andmarketing strategies and then establishes a designs of manufacturing system to support them [25-26] ,the following change program is proposed for the manufacturing strategy [27] : (1) gain topmanagement commitment in both time and resources; (2) evaluate the strategic position of thecompany; (3) review in a discussion group the existing primary and secondary requirements of themanufacturing strategy in light of the corporate strategy; (4) brainstorm issues surrounding theserequirements; (5) categorize these issues in terms of people, machine, process, and plan; (6) carry outa cause-and-effect analysis; (7) prioritize the identified causes; (8) set initiatives to address prioritized

    issues; (9) form teams of inspired people and implement these initiatives; (10) measure the newprocesses and compare the results against the expected results to spot and make up for anydifferences; (11) analyze the differences to determine their cause; (12) evaluate the strategic positionof the company. For the manufacturing activities improvement, the following change program isproposed [28] : (1) for each manufacturing activity the following questions are asked: 1.1. What isvalue added? 1.2. What activities can be joined? 1.3. What activities can be discarded? 1.4. Whatactivities can be done in parallel? (2) remove the non-value added manufacturing activities; (3) jointthe possibly joined activities; (4) have the activities that can be done in parallel done in parallel if theavailable resources permit.

    Manufacturing team leaders should be the focus of training efforts since they are the change agents tolead improvements in performance as the implementation of the proposed HLAMS should be pushimplementation by the manufacturing team leaders rather than pull implementation by the teamthemselves. The implementation of the HLAMS necessitates building culture, structure, and systems.Building culture requires the following: (1) culture development requires leadership with a continuous

    passion for perfection to create attitudes in all employees so that their behavior positively influencesproduct and service quality; (2) culture development also requires the empowerment of all employeesin the pursuit of quality; (3) team work implies that there is an organized, engaged, and self-disciplined team; (4) it is instilled in all staff that poor quality is a major waste and must be improvedto "near perfect", by continuous improvement with employees who are enabled to solve problemsusing tools such as Five Whys.Building organizational structure comprises the following: (1) low and high level ownership of quality; (2) technical and management support to resolve problems; (3) removal of indirect workers,adopting narrow job classifications, and adopting cross training; (4) short feedback loops based on aflat organization structure; (5) mechanisms for continuous improvement with routine daily stand-upteam meetings to flush out problems; (6) managers act as facilitators and provide mentoring.There are two types of quality systems: problem preventive system and problem corrective system.

    While the problem preventive quality system prevents problems from happening in the first place, theproblem corrective quality system deals with problems only when they arise. The HLAMS adoptshybridization of these two quality systems in terms of (1) instilling flexibility into the design andmanufacturing processes for embracing change; (2) adopting robust design of product using QualityFunction Deployment (QFD) to satisfy customers and stakeholders and using Design for Manufacturein order to provide the manufacturing and transportation processes with what these processes need;(3) adopting robust design of processes using Five Ss and Poka Yoke; (4) adopting systematicprocedures of doing things using ISO and QS standards; (5) detecting problems that can arise as earlyas possible using Statistical Process Control, Management By Walking Around, customer satisfactionsurveys, staff surveys, quality standards audits, Kaizen continuous improvement events, product stripdown, and inspection and testing; (6) analyzing the root causes of those problems and removing thoseroot causes using Pareto analysis, Ishikawa/fishbone diagrams, Five Whys, value stream mapping,and FMEA. The pragmatic reader might now well ask: How valid is the strategic facet of the

    proposed HLAMS? The next section will answer this question.

    VI. VERIFICATION AND VALIDATION OF THE IMPLEMENTATION OF THESTRATEGIC F ACET OF THE PROPOSED H YBRID L EAN -AGILEM ANUFACTURING SYSTEM

    The implementation of the strategic facet of the proposed HLAMS is verified in this section bytesting the research hypothesis. In an endeavor to verify and validate the implementation of thestrategic facet of proposed HLAMS, product and service managers of three Ground vehiclemanufacturing companies and OEMs were interviewed and their annual reports were reviewed withregards to the strategic facet of the proposed HLAMS. In addition, the annual reports of additionaltwenty seven Ground vehicle manufacturing companies and OEMs were reviewed in this regard.Historically, Taiichi Ohno and Shigeo Shingo developed the Toyota Production System from which

    247 Vol. 5, Issue 1, pp. 241-258

    the lean manufacturing principles were derived over a period of 20-30 years [ 33]. Thus, in anendeavor to double check the relevance of the implementation of the strategic facet of the proposedHLAMS to the real world of the automotive business, the General Motors Production System as anautomotive sector leader, is reviewed in this section as a typical case study on the proposed HLAMS.

    6.1. Verification of the Implementation of the Strategic Facet of the Proposed HybridLean-Agile Manufacturing SystemThe sources of competitive advantage in automotive sector are: (1) market position; (2) competitiveresources in terms of brand equity, systems, skills, market share, and patents; (3) learningorganization [34-35, 16] . Assuming equal weight of each of these sources of competitive advantage inautomotive sector, the proposed manufacturing system thus can improve on 39% of them since itimproves on systems (6% of the sources of competitive advantages) as well as on learningorganization (33% of the sources of competitive advantages). Therefore, almost one third of thevariation in successfully dealing with the sources of competitive advantage in automotive industry canbe explained by adopting the technical facet of the HLAMS. Therefore, the alternate hypothesis is trueand the implementation of the strategic facet of the HLAMS is positively correlated with firmsmanufacturing business success in automotive sector.

    Causality in this study is determined according to the percentage of variation in manufacturingbusiness success in automotive sector due to a variable (r 2) of a correlation coefficient (r). For whetheror not correlation does not necessarily mean causality, the following measure were taken: (1) thepercentage of variation in manufacturing business success due to the variable (r 2) has been calculated;(2) reliability (Cronbach's Alpha) analysis of the data collected has been performed with a result thatsatisfies the minimum acceptable value of Cronbach's Alpha which is 0.7; (3) both sampling designand the sample size are important to establish the representativeness of the sample for limitedgeneralizability; in the sample design, thus, probability sampling design of simple random samplingwas used for its cost-effective and fair statistical results with more than 50% of the ground vehiclemanufacturing companies included in the statistical sample; in addition, those included automotiveOEMs and manufacturing companies hold collectively more than 50% of the global market share inthe automotive market sector; (4) in order to further establish the representativeness of the sample forlimited generalizability, sample size of 30 is adopted since it is the minimum statisticallyrepresentative sample size [36, 37] . This leads us to elaborate on the case studies investigated in thisresearch.

    6.2. Validation of the Implementation of the Strategic Facet of the Proposed HybridLean-Agile Manufacturing System and Case Studies

    The validity of the research results has been tested in terms of four key validity types; firstly, in termsof statistical conclusion validity, since the resulted relationships are meaningful and reasonable;secondly, in terms of internal validity, since the results are causal rather than being just descriptive;thirdly, in terms of construct validity, since the results represent what is theoreticallyintended; fourthly, in terms of external validity, since the results can be limitedly generalized to thepopulation of automotive manufacturers since the statistical sample was representative. An importantand study-worthy practical example of agility combined with leanness in the global arena is China.Chinas biggest threat to world manufacturing is not only low cost but also quick -to-market. Almostevery plant in China boasts that it could design, develop and manufacture products in China fasterthan it could overseas. Sometimes this occurs because the intense competition for the growing internalChinese consumer market forces companies to be more nimble and innovative than their competitors.For instance, due to the booming Chinese auto industry, one-third of all growth in annual global autosales has been almost taking place in China [38] . This is why all of the major auto makers in the worldhave established a manufacturing presence in China, mostly partnered with one of the state-ownedChinese automotive enterprises that have had strong-enough management to survive the transition to amarket economy.A hybrid lean-agile production system should be designed to flow, and automation should be selected

    after deciding how best to improve flow and boost flow [ 39-40 ]. In order to compete in the Chinesemarket, which was almost doubled recently, many global automakers, such as the General Motors

    Corporation, have established their own China-based design studios and tooling facilities in order tospeed up their development of auto products custo mized to the Chinese consumers tastes. Some of these ideas and products can also be used worldwide. This can foster a recent perception that in Chinanothing is different, but that it happens cost-effectively and five times faster. Such increased speed-to-market could be because cheap technical labor in China can enable enterprises to put more minds atwork on a design problem than they could economically justify in dozens of other countries. Forinstance, in China an automaker is able to employ an army of highly-skilled sculptors who canquickly design and hand-make prototypes for consumer testing, and a legion of highly skilledmachinists who can turn the best designs into injection-mold dies within a few months. As a result,such an automaker can go from concept to production in almost 9 months; a period of time shortenough to enable such an automaker to have a comparative advantage in automotive sector.Consequently, strategically integrating comparative advantages can be a sustainable competitiveadvantage for the enterprise in the marketplace. Apparently, being lean only can harm the availabilityattributes of products and related services to customers. Meanwhile, being agile only can preventperformance on the reasonable cost attribute of products and related services to customers. TheChinese manufacturing approach in this context gives extra credibility to the validity of the proposedHLAMS in striking such a balance effectively.

    The General Motors Production System, as an automotive sectors lea der, is reviewed as a typicalcase study of the proposed HLAMS, in order to double check the relevance of the proposed system tothe real world of the automotive business. By reviewing The General Motors Production System inlight of the leanness assessment table and agility assessment method, Appendix A and Appendix B,respectively, it has been found that General Motors Production System had two shortcomings. Thefirst of these two shortcomings, which is related to leanness, was its deficiency in managing thechange towards lean manufacturing. The other shortcoming, which is related to agility, was the lack of strong relationships with suppliers in the General Motors Corporation supply chain. TheCorporation has recently recognized these shortcomings and has recently acted to resolve them. In anendeavor to resolve the deficiency in managing change towards lean manufacturing, General MotorsCorporation has established in 2003 its first ever lean and flexible plant. This plant is situated inMichigan, USA. Also, the Corporation has recently revisited and reestablished its entire value chain,

    with great emphasis placed on strong relationships with its suppliers and dealers. For instance,General Motors Corporation has acquired 10% of Mansour's Automotive Company share equity, theexclusive distributor of General Motors vehicles in Egypt, in 2001, as a means of moving forwardvertical integration in the General Motors value chain. These findings uphold the proposedhybridization of leanness and agility as a way towards sustainable competitiveness in automotivemanufacturing business.

    VII. DISCUSSION AND C ONCLUSION The challenge that faces automakers is to strike a balance between the current order-winning criterionof both cost and availability of products and related services without compromising quality. Thisresearch has aimed to help automakers to overcome this challenge through proposing a method to

    implement the manufacturing system that hybridizes the strategic attributes of both the lean and agilemanufacturing systems together in one manufacturing framework that meets the three levels of flexibility and responsiveness in automotive sector.The study has identified the sources of uncertainty in product design and manufacturing which are theroot causes of risk in product design and manufacturing and has presented a method to deal withthem. In addition, the study has proposed a risk management action plan that consists of three phases:(1) before the beginning of the product design process, (2) during the product design process, (3)before the beginning of and during the manufacturing process.The implementation of the strategic facet of the HLAMS is divided into short-term and long-termstrategies. In the short term, the assessment of the current state of the manufacturing system withrespect to the HLAMS is carried out, a change plan towards the HLAMS is set, and the Five-Smethod is applied throughout the entire value chain. In the long term, the change plan towards the

    HLAMS is carried out and the HLAMS should be fully implemented. In order to facilitate theimplementation of the strategic facet of the proposed HLAMS, the study has proposed

    implementation plan of the proposed manufacturing system for both the enterprises which havealready established their manufacturing business and for the enterprises which are going to establishtheir manufacturing business.The study has suggested assessing the lean capabilities of a manufacturing enterprise in terms of eleven capabilities which are inventory, team approach, processes, automation, maintenance, layout &handling, suppliers, set-ups, quality, retailers, and scheduling & control. The agile aspect of thestrategic facet of the proposed manufacturing system consists of delivery reliability and agilityasse ssment. The enterprises agile capabilities are suggested to be assessed against the agilecapabilities which are organization, process, technology, and people. Each of these four capabilities isassessed based on three aspects: goals, design, and managerial measures.There have been some limitations of this research which are: (1) due to the fierce competition in theautomotive market, some information is considered confidential and hence is unavailable; (2) theinterviews were conducted using open-ended questions; these interviews were structured and face-to-face interviews since the interviewees preferred to be interviewed with open-ended questions; (3) thescope of the study covers only the automotive sector.The study has shown that implementing the hybridization of the lean and agile manufacturing systemstogether can be strategically and industrially valid. The study has presented that the implementation of

    the strategic facet of the HLAMS is correlated with the manufacturing enterprises manufact uringbusiness success in automotive sector. It has been found that almost one third of the variation in themanufacturing business success can be explained by adopting the HLAMS. The cost demanded by theimplementation of the HLAMS can be moderated by the following benefits: (1) reduced operationalcost; (2) reduced time to market.

    VIII. FUTURE R ESEARCH The HLAMS presented in this study exhibits further research. The future research proposed in thepresent study includes: (1) conducting industrial experiments for further validating theimplementation of the strategic facet of the HLAMS, (2) reviewing further relevant industrial casestudies for further validation.
