II. Introduction: Prof. Narayana Rao's Vision for Industrial Engineering

A. Overview of Prof. Narayana Rao's Contributions to Industrial Engineering

Prof. Narayana Rao 

A central tenet of his philosophy is the definition of industrial engineering as "profit engineering." He asserts that organizations failing to embrace its principles are "unnecessarily foregoing profits inherent in the products that it developed and designed". This core perspective highlights the direct financial impact and strategic imperative of the discipline. The extensive industrial leadership experience of Prof. Narayana Rao and his explicit characterization of industrial engineering as "profit engineering" are intrinsically linked. This suggests that the fundamental purpose of industrial engineering, in his view, is to generate profit, and therefore, "Applied Industrial Engineering" represents the practical, results-oriented pathway to achieve this objective. This perspective implies that for Prof. Narayana Rao, the "applied" dimension of industrial engineering is not merely a descriptive term but a core philosophical necessity. It further suggests that the discipline's true value is ultimately measured by its tangible economic outcomes, such as increased sales, reduced costs, and enhanced profitability. 

Prof. Narayana Rao has formalized his perspective through the "Taylor - Narayana Rao Principles of Industrial Engineering," which builds upon Taylor's scientific management to provide a comprehensive framework for achieving modern industrial efficiency.   

B. Contextualizing "Applied Industrial Engineering" within his Focus Areas

Prof. Narayana Rao explicitly identifies "Applied Industrial Engineering" as one of the critical focus areas within the broader discipline of Industrial Engineering. This classification positions it as a distinct, yet integral, component of his comprehensive framework.   

His outlined focus areas for industrial engineering are extensive and include Productivity Science, Industrial Engineering Strategy, Facilities Industrial Engineering, Product Industrial Engineering, Process Industrial Engineering, Industrial Engineering Optimization (IEOR), Industrial Engineering Statistics (IE Statistics - Six Sigma Optimization), Industrial Engineering Economics (IE Economic Analysis), Human Effort Industrial Engineering, Productivity Measurement, Productivity Management, and Data Processing and Information Systems for Industrial Engineering.   

The inclusion of "Applied Industrial Engineering" alongside these specialized areas indicates that it serves as the practical culmination or synthesis of these individual disciplines. It emphasizes the implementation and real-world impact of industrial engineering knowledge, translating theoretical understanding into tangible results. Prof. Narayana Rao's diverse background, encompassing mechanical engineering,industrial engineering and  industrial management, coupled with his broad enumeration of IE focus areas  (from quantitative fields like "IE Optimization" to human-centric areas like "Human Effort IE"), points to a significant emphasis on the synergistic integration of knowledge. The general definition of industrial engineering itself is inherently multidisciplinary, combining various sciences and management principles. Therefore, the concept of "Applied Industrial Engineering" within Prof. Narayana Rao's framework implies a profound focus on strategically combining insights from engineering,  mathematics, natural sciences, social sciences, and management to develop holistic solutions for complex, real-world problems. This underscores that effective "application" in industrial engineering necessitates a broad, interdisciplinary perspective to optimize integrated systems comprehensively.   Specifically applied industrial engineering highlights the fact that as new technologies are developed, applied industrial engineers also develops with the tagline - IE in New Technologies and IE with New Technologies. As engineers with focus on productivity and efficiency, industrial engineers have to contribute to systems, processes and operations using the new technologies and producing products or services employing  engineering systems.

III. Defining Applied Industrial Engineering: Principles and Objectives

A. Prof. Narayana Rao's Core Explanation of Applied Industrial Engineering

Prof. Narayana Rao's explanation of "Applied Industrial Engineering" fundamentally emphasizes its practical, hands-on character, with the primary aim of enhancing productivity and overall system efficiency. It necessitates a scientific approach to analyzing every element within a "man-machine system's work," thereby departing from less systematic or intuitive methods to achieve quantifiable improvements in efficiency and productivity.   

A crucial aspect involves the engineering of methods, processes, and operations to effectively leverage the inherent principles governing the interaction and utilization of machines, human labor, materials, and other resources. This systematic design approach is essential for ensuring optimal performance. Furthermore, the applied nature extends to the continuous improvement of any product throughout its entire lifecycle, from its initial design phases to its eventual disposal. This holistic perspective is critical for ensuring sustained value creation and long-term viability.   

B. Key Principles Emphasizing Practical Application, Efficiency, and Productivity

Prof. Narayana Rao's framework for Applied Industrial Engineering is built upon a detailed set of principles that underscore its practical and results-oriented nature:

Productivity Science and Engineering: This principle involves the practical application of scientific methodologies to systematically enhance productivity across all operational facets. It moves beyond mere observation to a structured, scientific approach to improving output.   

Ubiquity of Industrial Engineering: Prof. Narayana Rao emphasizes that industrial engineering principles are broadly applicable across "all branches of engineering". This highlights its universal practical relevance, indicating that its methods and philosophies can be adapted to diverse technical and organizational contexts beyond traditional manufacturing.   

Machine Utilization Economy: A practical goal is to develop and apply principles for the most efficient utilization of all resources within engineering systems, aiming to minimize waste and maximize output. This extends to selecting equipment for multiple processes and improving machine performance to increase productivity.   

Optimization and Economics: Applied Industrial Engineering inherently involves the use of practical optimization techniques to identify the best possible solutions, always considering the economic implications and striving for profitability. This includes aspects like industrial engineering economics and return on investment.   

Implementation Team Membership and Leadership: Industrial engineers play a crucial practical role not just in designing solutions but also in leading and actively participating in the implementation teams that bring these solutions to fruition. This emphasizes the hands-on, execution-focused nature of the discipline.   

Human Effort Engineering and Motion Economy: This practical area focuses on engineering human effort to increase productivity, applying principles of motion economy to optimize physical tasks, and critically, ensuring the comfort and health of operators. This includes redesigning products and processes to reduce discomfort for operators.   

Work Measurement: A fundamental practical tool, work measurement involves systematically collecting and analyzing data in an industrial setting to establish performance standards and identify areas for improvement.   

Training and Education: Beyond initial skill development, there is a continuous emphasis on productivity training and education for all levels of personnel, fostering a culture of continuous improvement.   

Employee Involvement and Incentives: Practical application necessitates actively engaging employees in continuous improvement initiatives and implementing incentives that reward productivity gains. This promotes a shared commitment to efficiency.   

Hearty Cooperation: Fostering strong cooperation between management and the workforce is identified as a practical necessity for the successful and sustainable implementation of industrial engineering solutions.   

Productivity Management, Measurement, and Cost Measurement: These are identified as key practical functions, ensuring that improvements are tracked, managed, and their financial impact quantified. This includes collecting and analyzing data to redesign products and processes for profitability.   

C. Distinction and Relationship with General Industrial Engineering and Industrial Engineering Technology

Understanding "Applied Industrial Engineering" within Prof. Narayana Rao's framework benefits from a clear distinction between general Industrial Engineering (IE) and Industrial Engineering Technology (IET) programs, particularly in terms of their academic rigor and practical emphasis.

General Industrial Engineering (IE) is a discipline broadly concerned with the "design, improvement, and installation of integrated systems of personnel, material, and equipment". It is characterized by a strong foundation in mathematical, natural, physical, and social sciences, alongside rigorous engineering analysis and design principles. Often described as "math and statistics engineering," it requires extensive coursework in these quantitative areas, providing a deep theoretical understanding that enables complex problem-solving. Programs in Industrial Engineering are typically accredited by ABET, which signifies adherence to high standards of engineering rigor and comprehensive curriculum. Graduates are prepared for roles that involve designing cost-efficient systems and enhancing production operations.   

In contrast, Industrial Engineering Technology (IET) programs focus more on the "practical application of engineering principles" to optimize processes, increase efficiency, and solve complex challenges, particularly in manufacturing, logistics, and healthcare. While still utilizing a systems approach, the emphasis is on applying established principles and management practices, often through hands-on activities and experiments. IET programs may be accredited by ATMAE (formerly NAIT), which some sources suggest can be a "pale comparison" to ABET programs in terms of perceived depth and potentially impacting earning potential for graduates.   

For Prof. Narayana Rao, "Applied Industrial Engineering" is presented as a focus area within the broader IE discipline, rather than a separate degree type. This suggests that the "applied" aspect is the    outcome or purpose of industrial engineering, regardless of the specific academic pathway (IE vs. IET). It emphasizes translating theoretical knowledge into tangible, real-world solutions. This perspective highlights that while the    spirit of "applied" is central to all industrial engineering—the overarching goal of translating knowledge into real-world improvements—the academic pathway chosen has substantial implications for how that "applied" knowledge is developed and recognized. The market's differentiation based on accreditation indicates that a strong theoretical and mathematical foundation, characteristic of ABET-accredited IE programs, is often perceived as providing a deeper, more versatile capability for complex problem-solving, even for roles that are inherently applied. This creates a nuance where the intent of the discipline is applied, but the foundational rigor of the education dictates the breadth and depth of that application.

The historical context of industrial engineering further illuminates its inherently applied nature. Prof. Narayana Rao's principles build upon Taylor's scientific management. The historical development of IE reveals its role as the "driving force" behind the success of mass production, notably during the U.S. Civil War, through advancements in standardization and efficiency. Furthermore, Operations Research (OR), a closely related field and a fundamental component of industrial engineering, originated as a "military term" for developing optimal strategies using mathematical tools. This historical perspective underscores that the "applied" nature of industrial engineering is not a contemporary innovation but a foundational characteristic, born out of urgent practical needs for efficiency and optimization in large-scale, complex systems like industrial production and military logistics. The discipline's evolution is deeply intertwined with solving critical, real-world problems, establishing a legacy of practical impact that continues to define "Applied Industrial Engineering" today. The synergy between industrial engineering and operations research, particularly in areas like supply chain management, further solidifies this historical and practical interdependence.
