" In those manufacturers who are attaining lean enterprise-level performance, the cultures of their companies have become incredibly focused on metrics, and in fact the organizations themselves have become so metrically driven that the culture itself embraces the concept of measuring performance and improvement (Nash, Poling 2007).

Lean positioned for cost cutting vs. customer-driven change. This is also a critical mistake many manufacturers make, and often becomes the main focus these companies continue to pursue, as opportunities to better integrate their strategies with customers, suppliers, buyers, and service organizations present themselves.

Evolution of the Lean Enterprise

Manufacturers have continually struggled to gain the advantages of lean manufacturing, starting first with manufacturing processes at the shop floor level and progressing to a vision of implementing an entire lean enterprise. What's become essential in the pursuit of the lean enterprise are the creation of strategies for driving waste of all types (time, logistics, costs) out of the enterprise. Table 1, Characteristics of a Lean Production System, show the specific lean production processes and accompanying system change initiatives, an analysis based on the research completed by the MIT Lean Aerospace Initiative, which has applicability to the auto industry as well.

Characteristics of a Lean Production System,

Lean Production Process

System Change Initiative

Focus

Production line (tasks, activities, and cells)

Single organization (departments, processes, suppliers, and customers)

Practices

Cellular manufacturing, quality circles, supplier relationship management, pull production, reengineering setups.

TQM, JIT, Six Sigma and, process reengineering

Performance

Measurement

Systems

Takt time, on time delivery, first time through safety performance production rate

Visibility - real-time reporting and the use of analytics to track the entire value chains' performance

Casual relationships (production tasks and activities)

Use of single version of the truth and single information reporting

Quality, delivery, process time, cost, flexibility, customer satisfaction

Balanced set of strategic metrics (financial and non-financial)

New methods of cost accounting (ABC, target costing) down communication

Internal vs. external focus (benchmarking and self-assessment)

Process management and measures (value delivery)

Framework for Evaluating Lean Process Maturity

Based on the collective work completed at the Massachusetts Institute of Technology (MIT) Center for Transportation and Logistics relating to manufacturers and the theoretical frameworks developed by the MIT Lean Aerospace Initiative the following benchmarking framework has been created. The 18 life-cycle lean processes (Bennett 2003) measured in this benchmarking instrument include the following:

Business Acquisition and Program Management

Leverage lean capability for business growth

Optimize the capability and utilization of assets

Provide capability to manage risk, cost, schedule, and performance

Resource and empower program development efforts

Requirements Definition

Establish a requirements definition process to optimize life-cycle value

Utilize data from the extended enterprise to optimize future requirement definitions

Develop Product and Process

Incorporate customer value into design of products and processes

Incorporate downstream stakeholder values into products and processes

Integrate product and process development

Supply Chain Management

Define and develop supplier network

Optimize network-wide performance

Foster innovation and knowledge-sharing throughout the supplier network

Produce Product

Utilize production knowledge and capabilities competitive advantage

Establish and maintain a lean production system

Distribute and Service Product

Align sales and marketing to production

Distribute product in lean fashion

Enhance value of delivered products and services to customers and the enterprise

Provide post delivery service, support, and sustainability

In creating a questionnaire and research instrument from these 18 factors, it's critical to take into account the maturity levels of each attribute as it relates to the lean performance of an entire organization.

It is not enough to simply look at a binary, either/or condition for each factor. It is rather the level of maturity on each of these 18 attributes that determines an organizations' potential for attaining best practices as a lean enterprise. Using a four-point scale applied to each of these factors yields a self-scoring questionnaire which is shown in the following table. Giving just one answer for each of the 18 factors, calculate a given process's lean enterprise performance with an organization of interest. The development of aggregate scores by each specific area will define the level of process maturity as defined by their lean characteristics.

After having scored an organization and its processes on its lean initiatives, use the following table to define where an organization is on the Lean Enterprise Maturity Model:

Score

Level in the Lean Enterprise Maturity Model

Orchestrating - Where an organization has a very high level of cross-department and division collaboration and often has a corporate-wide edict that forces lean enterprise principles deep into the organization.

Collaborating - a series of process -- and it-based infrastructures exist to ensure cross-department and cross-divisional collaboration.

Anticipating level - Marked with in-division collaboration only.

Isolated approach to lean - Heavily influenced by silos

The following graphical representation of the Lean Enterprise Maturity Model illustrates how each level of maturity varies by Process Maturity and Information Maturity. This graphical concept of a maturity model was originally proposed by AMR Research in the definition of Demand Driven Supply Networks (DDSN) maturity levels, and has direct applicability to lean enterprises' levels of lean manufacturing maturity. Both process and information maturity is measured, progressing from being purely reactive from a process standpoint through creating processes through anticipating departmental requirements, through collaborating to orchestrating processes to attain level process best practices.

Recommendations for driving Lean Process Transformation

In the studies referenced implementing lean manufacturing strategies for automotive refurbishment suppliers the following key recommendations emerge:

Greater system-level integration with downstream stakeholder values and greater visibility into customer demands. Relating back to the discussion at the beginning of this paper how the highest performing manufacturers are able to eliminate several types of waste while concentrating on delivering exceptional value to their customers is a key success factor in attaining lean manufacturing strategies. Using the 18 attribute lean manufacturing framework to evaluate an organization can serve as the catalyst for further diagnosing of processes' areas of strengths and weaknesses.

Delivering greater process standardization and greater cross-functional communication eliminates wasted time, duplicated processes, and lost opportunities to better serve customers. In several of the case studies that MIT and others have cited as examples of best practices in lean enterprises, the senior management teams worked to tear down the silos between departments by actively encouraging and rewarding cross-department and cross-division collaboration. The greater the level of integration between functions and processes, the greater the reduction of waste in over-processing, waiting, transport, processing, inventory carrying costs, in addition to defects & spoilage (Monroe 2006).

Integrate and reward lean initiatives success and include them in both strategic planning and production systems planning. The automotive manufacturers and automotive refurbishment companies gaining the greatest competitive advantage through their efforts to become lean enterprises have started first with smaller projects and then progressed to enterprise-wide ones once the payoff has become clear.

Integration of environmental protection, compliance, health and safety systems corporate wide. Clearly the need for mitigating the significant costs of compliance as they relate to the use and disposal of chemicals and raw materials used in the production of complex products are many manufacturers' most critical concern, and this area of automotive manufacturing is gaining in importance as governance, risk and compliance (GRC) continues to gain in prominence as a strategic initiative within organizations. The development of lean initiatives that include GRC components have increasingly been developed as a result of global compliance requirements as well. The….....
