Quality and Industrial Productivity Measurement and Analysis


Quality improvement is a concept, which began several centuries ago. Traceable to the Inter-war development of aircraft factories, the first aircraft factory began operation in the year 1916. Four of the companies produce more than 2000 aircraft for military operations for Romania’s use in the Second World War. During this period, the concept of quality management was still a strange idea. This research, however, presents important lessons about quality management exhibited in the Romanian aeronautical industry. Blended with the six sigma DMAIC model, the research paper will offer insights for conducting a quality improvement process in organizations.


The rapid globalization witnessed particularly in the 21st Century have resulted in stiff competition in almost every financial industry. Organizations and companies are now under immense pressure to remain competitive and achieve business success. In an attempt to become excellent, companies have to conduct various quality improvement measures of their goods and services. However, modern quality improvement procedures are undergoing a paradigm shift. The growing consumer awareness of quality and safety of products and the changing consumer demand patterns have made organizations to align their products with consumer needs and preferences alongside producing quality and safe products. Quality is thus defined and build on the bases of customer needs. Continuous improvement approaches have been initiated in the manufacturing sector to ensure the end product satisfies the end consumer.

The foundation of quality improvement in manufacturing companies rotates around sound process methodologies blende with suitable performance measures. Over the last two decades, quality progress has availed a wide base of continuous improvement mechanisms with the aim of hastening quality improvement process and productivity measures which aid business growth. The six sigma is one such a constant improvement tool applied in most of the competitive global companies. The Romanian Old Kingdom Inter-War aeronautical factories have long been used to study quality improvement principles that other organizations can use to evaluate their quality and productivity performance. This research paper aims to incorporate the Romanian Inter-War quality improvement principles and the six sigma model to conduct and analyze quality and productivity measures in industries.

The DMAIC will be used as the principal tool for conducting a six sigma analysis. The methodology is highly data depended on analyzing causes of falling quality and productivity levels in any organization. In this research paper, six sigma model will be represented using a research diagram. The DMAIC focuses on expanding the present process capabilities and identification of new opportunities for improving both the current and the future quality and productivity processes. The six sigma model is thus included in this research paper because it enables companies to become customer driven. The DMAIC model incorporates multiple techniques and tools to vary management and reduce defects in operations. The essence of conducting quality and productivity improvement measures is to attain customer satisfaction, decrease defect levels, achieve real-time delivery and to improve the productivity concerning marginal increment of the cost quality.

The Quality Principles the Romanian Aeronautical Companies Operated

The first aeronautical, industrial plant is now over a century old since its launch in 1916. The old Romanian kingdom was among the few nations in the world that had the know-how to develop flying machines that were heavier than air. The organization structure of these companies played a key role in making the factories successful. However, in 1946, there was a ban on the production of military aircraft in Romania as a result of the Paris Peace Treaty 1. This came with significant consequences to the company including loses in revenue. Since then, the Romanian Aeronautical Companies have continued to strive for excellence through the use of their seven quality principles in all of their units. The quality principles sprung from the technical committee on quality management and assurance of the companies which was endowed with huge competence and experience. These principles are as follows; client orientation, leadership, personal commitment, customer orientation, systemic approach to management, improvement, evidence-based decision making and lastly relations and connections.

Client orientation as the first principle focuses on the fact that companies depend on client and stakeholders and thus, the company must The used the understanding of their clients present and future needs, which they used to enhance the quality of aircraft so they would exceed their clients’ expectations 2. The client approach was made possible in the Romania Aeronautical factories through personalizing orders for their clients who then were the Romanian Army.

The companies also put in place strong leadership as the second quality principle. The personnel working for the organization had to know be fully involved in accomplishing the objectives and mission of the companies. The manager had to use their skills and charisma to communicate, train and offer proactive decisions, which ensured quality. Continuous communication between the top management and the employees as well as other stakeholders in the companies provided transparency and well-informed decisions 3. Moreover, the third quality principle emphasized on personal commitment and dedication. This principled aimed at developing employees with high capabilities in all levels of the companies with the aim of delivering value to the organization. The Romania factories had designers and builders who were highly qualified besides been paid well and highly esteemed.

Process approach regarding systemic approaches to management formed the fourth quality principle that the Romania aeronautical companies implement. This approach stipulated that there is a need for a total commitment that ensures efficient use of skills and resources for the best benefit of the organization 2. The process management and system control involved the planning, doing, controlling and acting cycle often referred to as the Deming cycle. The Romanian companies implemented this principled via separating design and production to be different departments which ensured efficiency.

The improvement quality principle became the fifth principle implemented by the organization. It is only through a consistent and constant focus on improvement that organizational success is achieved. The Romania Interwar companies constantly diversified its production through utilization of new technologies to improve their performance. The sixth principle was proof-based decisions which required that all decisions taken must be backed by evidence, therefore, implying the use of data to make all decisions, which eventually leads to expected outcomes.

The seventh principle is relations principle which stresses the importance of management to form a relationship with suppliers and other stakeholders to optimize organizational performance. All these principles yielded the now quality improvement concept 4. Romania companies maintained a stable relationship with its suppliers such as the engine, chemicals fabric, and wood suppliers. Good relations between the factories and other stakeholders and interested parties such as the ‘Aviation Corps of the Army,’ ministry of the Army helped the companies to optimize their performances as well as the development of subsidiaries.

Application of Six Sigma in Quality and Productivity Measurement and Analysis

The application of Six Sigma is developing and growing from the field of industrialization to incorporate all the manufacturing and business operations. These business operations include marketing and advertising services, transactions and some administrative services. The growth of the Six Sigma has been witnessed in areas that directly affect the consumer 5. Six Sigma is an organized method of strategic procedures that depend on the statistical and mathematical tools as well as scientific approaches that enhance reduction of consumer-defined defect rates. The Six Sigma approach for the finished projects include measure, analysis, improve and control for the procedural improvements. Besides, since the year the 1980s, the Six Sigma excellent management have appeared as key frameworks where to implement value-added enhancement. The Six Sigma started in the late nineteen eighty. It was therefore developed by Motorola company as a retort to demand their commodities that had many components, and that achieved low rates of defective in the function of products.

The real benefits of the Six Sigma started via the effort of Jack Welch, who was the chief executive officer of the General Electric company in the year 1995. Previously, Welch had observed the success experienced through a method used by Bill Smith. He intensively explored and supported the Six Sigma methodology in the General Electric. Moreover, the statistical measure of the rate of a defect within a structure is reinforced by the techniques and methods of statistics. It is a method that represents a systematic way of to increase improvement as well as focus on reducing the defect rates of 3.4 in every million chances that occur. Within a system, defect rates bring an example useful in illustrating the Six Sigma.

The variation between 99 percent quality and superior rates in the model of Six Sigma indicate a different situation, and thus this is used to indicate the meaning of Six Sigma in a real application. For instance, in a case where a certain post-office worked at ninety-nine percent rating quality for three hundred thousand letters provided, there would be three thousand letters that are not delivered, as compared to just one misdelivery only when the Six Sigma was used in operating the statistics 6. Besides, when the Six Sigma is used in determining the operation of stations and channels in televisions 99 percent, an estimate of one hour and sixty-eight minutes of bonus in a period of one week compared to 1.8 seconds found if the statistics are worked with the Six Sigma levels.

Additionally, the Six Sigma is highly applied in most manufacturing industries and organizations. The General Electric and Motorola companies are the most prominent organizations where the application of Six Sigma is utilized appropriately. Besides, it has contributed to the success of some construction industries. However, the current focus on the use of Six Sigma principles is majorly aiming in the service sector 7. Several and numerous business and organizations apply the Six Sigma in different ways and processes. It is used in diverse areas including in business and accounting, in the field of supply chain and management and human resource management.

The Six Sigma is also used in payrolls, hazard and safety engineering and other departments in enhancing the inventions and innovations of the industry. As evidenced by a company known as Raytheon Corporation that uses the Six Sigma in the sector of human resource management improvement, this model is significant in most business enterprises. Besides, the chief executive officers and financial officers in business can adequately utilize the applications of Six Sigma to ensure compliance with the Act of Sarbanes-Oxley 6. The financial sector and financial services become the most popular field where the Six Sigma is mostly applied. Moreover, as described by (xxxxx), the Six Sigma is also applied in improving the process of allocating the loans to students and showing how the creditors benefit. The Six Sigma becomes useful in the various banking industry and marketing processes.

Six Sigma DMAIC framework

The six sigma offers a platform for using quality and productivity measures through the application of DMAIC. The DMAIC stands for five stages which are ‘Define, Measure, analyze, improve and Control’ a process. These phases of a project life are further subjected to planning, doing, studying and acting (PDSA) framework often referred to as Deming cycle 8. The use of PDSA helps to arrive at quick decisions and actions which leads to sustainable improvements. During the process of applying each of the PDSA procedures, a manager uses several process improvement tools to achieve the desired outcome. Figure 1 depicts the DMAIC quality improvement process. The six sigma DMAIC methodology is useful in improving, optimizing and stabilizing a business process. The model relies heavily on data to improve a process.

Figure 1 Six Sigma DMAIC Framework

Definition Phase

The define phase majors on identifying the product or process that requires improvement. Notably, the definition stage involves several procedures such as processes of selecting the best project out of alternatives 4. This mainly involves choosing areas of business which needs the most improvement. Additionally, during this phase, the organization has to benchmark its key products and processes with those of its competitors. Moreover, at the end of this stage, full project approval is for signed and formalized.

Key details such as important metrics and scope of operating form part of the plan. The project plan then obtains sponsor approval before it is commenced. The team to spearhead the implementation of the project is then selected, and the project begins. Business actions such as mapping the overall business process or product including key value chain actors and stakeholders are done 7. Further, the product team identifies customer needs which revolve around the cost of the product, quality and speed of delivery. In this sense, a credible baseline is formulated in which clear and realistic goals and targets are defined and set alongside their financial implications well documented.

Measurement Phase

The phase is based on the ability of an organization to assess the performance of all the areas it needs improvement. The stage is characterized by selection of product characteristics. These product attributes include dependent variables, product mapping, constant measuring, recording the results and approximating both the short run and long-term proficiencies. In some occasions, one needs just to improve the measurement ability to achieve improvements 5. The measurement mechanisms must ensure minimal variation in the process variation and specification restrictions. Firstly, the area that needs to be measured is identified as the business activities continue.

This is followed by comprehensive data collection to ensure a quantifiable evaluation is made possible hence the performance will be based on observable data. Some of the data collected include time; sales made base on gender or type of customers and the number of defects encountered on the products 7. Also, key responses and product output metrics are specified. Baseline data is included to measure baseline product or process performance and to determine the level of improvement if any. Opportunities which can make quick wins to the organization are made as well as quick decisions to take advantage of such opportunities.

However, risk assessment of this opportunities has to be made. The low-risk attractive opportunities hence save times and energy besides saving costs of the analysis and control stages. For instance, opportunities such as step elimination, changes in procedures and application of simple communication improvements can win large for the company. These improvements add momentum to the product improvement process besides adding value and confidence to the organization at the initial stages of the project 8. The two kinds of measurement variation are distinguished. Reproducibility which means that different people can obtain dissimilar measurements arising from one similar activity. Repeatability or equipment variability on the other hand means that an individual obtains contrasting measurements for an identical process between progressive measurements.

Analysis Phase

The analysis phase involves analyzing and reviewing the critical performance aspects of the product or process. Gap analysis is done to identify the common factors that determine successful performance. Besides, causes evaluations become necessary which encompasses an iterative process revolving around hypothesis, observations and statistical tests. This forms the bases on which current performance hypotheses are made 2. It then follows that the best hypothesis becomes chosen and those that are termed unrealistic or impossible are neglected. These hypotheses are validated via statistical methods as well as approximating their effect on the performance metric. The manager has thus to determine if there is a quantifiable relationship between the causes and or the critical factors. In this sense, the causes are quantified, and the causes for improvement is vital in this phase.

Improvement Phase

The improve phase links to the selection of the process or product performance attributes which need improvement. Two types improvement include incremental and transformational. The transformational or exponential improvements tests the initial process hypothesis and designs the product or process higher possibilities collectively 5. Incremental improvement, on the other hand, usually is small and successively increase from one step to another which ultimately leads to higher improvements.

Generation of many potential solutions for the causes discussed in the analysis stage helps to narrow down on specific solutions or combining them to form an overall solution that leads to improvement. Companies usually develop to process maps and implementation plans to carry out quality and productivity activities 4. The most straightforward and easiest solutions among the alternatives are chosen and executed first. Further, the PDSA cycles come in at this stages to test the performance viability of the answers.

Control Phase

The control phase is commenced by establishing control mechanisms as well as monitoring the anticipated improvements. This stage aims at ensuring sustainable outcomes and is facilitated by the use of statistical process control tools. Many organizations create control plans to document any upgrades and failure areas 6. Additionally, financial outcomes are recorded for further review. The results of the review generate follow-on analysis, or many necessitate a revisit to some of the preceding stages.


Quality and productivity improvement measurement is an essential business operation that can lead to business excellence. The research paper has captured the seven quality principles that the Romanian Inter-War factories implemented to improve their performance and productivity. Additionally, the paper has captured the Six Sigma DMAIC model to explain the process and measurement of quality and productivity given a project to implement.
