Industrial Process Management Model to Improve Productivity and Reduce Waste
[ad_1]
1. Introduction
Our objective is to generate a model that results in a continuous improvement system tailored to a company, under the conditions of new data availability technologies (Big Data) and modern communication technologies, enabling real-time, holistic connections between the Gemba and management, promoting sustainability.
Our model innovates by combining the improvement cycles of kaizen and lean philosophies, real-time adjustment of action plans, concepts from the PID model, and the situational awareness model.
The developed model emerged from practice, being simple and integrable to Lean, control and standardization methodologies. As a result of its implementation, it was possible to achieve significant improvements in productivity and a digital record of situations that complements big data, in a relatively short implementation time and without large investments. Additionally, allowing the permanent establishment of group communication channels that strategically link individuals, raised situational awareness at higher levels of the organization and allowed more agile decision-making during interruptions.
In this publication we complement preventive efforts with an efficient corrective approach, which will define how to handle production interruption situations, in order to minimize their impacts and maximize the resilience of the production system as a whole.
The information flows in the processes are varied and, together, constitute what we know as big data. Although industry 4.0 has generated a considerable volume of information, allowing artificial intelligence to access and detect useful patterns of comprehension and predict failures or deviations in processes, since communication between human beings cannot always be controlled, especially when it is not possible and there is an explicit digitization of all information flows. This is even more complex in situations of implicit communication or in learning flows between apprentice and master, which are all subject to legal regulations that protect the privacy of workers.
How we control industrial processes is a question that has occupied us since the beginning of the industry. The PID (Proportional, Integral and Derivative) control model, conceived by the contributions of James Clerk Maxwell, Nicolas Minorsky and Edson Briggs in the 19th century and the beginning of the 20th century, allows for the regulation and stabilization of industrial systems effectively, being fundamental in the automation of industrial processes.
2. Materials and Methods
2.1. Description of the Proposed Model
Our model requires the selection of key areas of the manufacturing process, which will be responsible for perceiving and transmitting situations or events in real time. The selection of these key areas depends on each case in which it is implemented and are mainly defined, considering the sources that generate interruptions in the process and work teams already trained in the operation.
The communication tool or technology that will be used as a medium must be selected based on management requirements, allowing at least a flow of information, recording of operation situations, and fluid communication between participants.
This new model of group situational awareness focuses on effective collaboration and communication between team members with the goal of managing manufacturing operations efficiently. By combining situational awareness with PID control, the aim is to improve coordination and decision making in the environment of an industrial process. This joint approach offers benefits such as greater awareness of the current and future situation, more informed decision making, precise control of process variables, and improved efficiency and productivity in manufacturing operations. This model could find applications in various industries, such as logistics, manufacturing, and health services.
At this point, the coordination group is in a specific situation, known to all participants in that particular group. However, there are participants who are part of more than one group, whom we will call transversal participants. These transversal participants have a higher level of perception, which we will call secondary perception, since it is based on the perception of multiple groups. Cross-cutting participants are responsible for perceiving situations between different groups and creating situational patterns or scenarios.
These patterns or scenarios may be difficult to perceive by participants in primary operational areas.
Primary and secondary perception and the detection of situational patterns are fundamental for the comprehension stage, which involves both individual and group cognitive work. This cognitive process depends on the skills, experience, and talents of the participants involved. During this stage, comprehension can be expressed explicitly through a message shared by one of the participants in the communication group. There is also the possibility of implicit comprehending, in which group participants are assumed to have complete knowledge of the situation or scenario, even if it is not explicitly discussed.
Explicit comprehension triggers an incremental process where participants share their opinions regarding the situation. This interaction is affected by factors such as the degree of influence of the participants, experience, and knowledge.
Although comprehension is not a projection of future situations, it delivers as a product a diagnosis that determines the actions to follow.
Before defining an action plan, it is crucial to carry out a careful evaluation to determine if the situation in question is known and if there is a previously established action plan, or if it is a special circumstance that has not yet been addressed by the team and requires an additional analysis.
-
Perception at the operational level: begins with the real-time capture of the state of the process and environment variables. In this stage, similar to an analog–digital converter (ADC) that converts an analog signal into a digital interpretation, the participants of the coordination system perceive the state of the variables or their rate of change and transform it in a message. This allows information to be shared in real time, improving both individual and group awareness. Furthermore, cross-sectional participants carry out secondary perception by perceiving the status of different groups. This secondary perception becomes the output of this stage.
-
Perception at the tactical level: The participants of the communication groups that belong to the tactical–functional departments are generally transversal participants and their main contribution is to influence the comprehension of the state of the system with their opinions.
-
Perception at a strategic level: The directors in charge of generating strategy are responsible for perceiving the external and internal events of the company, for this they must build constant monitoring and follow-up systems, which aim to maximize internal and external situational perception.
-
Comprehension at an operational level: Begins with the creation or clear identification of a situation or situational pattern. This information feeds a situational statistic and then advances to a stage in which the established guidelines are consulted to proceed in common or special situations or patterns. Quick identification of a situation or pattern is crucial to ensure prompt implementation of the action plan. However, special situations require a thorough review by the tactical area, since tactical action plans must adjust to the manufacturing strategy.
-
Comprehension at the tactical level: Implies a high degree of situational awareness, since at this level information from both the operational and strategic levels are integrated. This allows for a complete comprehension of the situation and, therefore, the responsibility for managing and creating situational statistics falls at this level.
-
Comprehension at a strategic level: It involves analyzing the competitive position, identifying opportunities and challenges, and establishing a strategic direction. The perception of relevant information, the visualization of situational patterns and multi-criteria evaluations are key elements in this level of comprehension. Furthermore, the importance of carefully reviewing special situations to evaluate their impact on the different strategic perspectives is highlighted.
-
Projection at a strategic level: It is a key stage for the future of the company, which is based on the perception and comprehension of the environment and interior of the company; subject to the objectives and strategic plans, the projection defines the company’s path to follow.
-
Projection at the tactical level: After comprehension, the adjustments made by management to the objectives and strategic plans, the tactical area projects the use of productive factors subject to capacity restrictions, the planning of new situations is often only an estimated value and is awaiting the results of the implementation.
-
Projection at the operational level: Once the operational area has understood the action plans adjusted by the tactical area, it proceeds to make a projection of the implementation of said plans. This projection involves simulating how current resources will execute new methods, product modifications, the use of new tools, or changes in working conditions. In common situations, this projection is known, and the results are estimated with high precision, which allows an immediate response; in special or new situations, you must wait for execution to see results.
-
Decisions at a strategic level: Corresponds to the decisions to adjust the objectives and strategic action plans contained in the company’s strategic map. On some occasions, change programs are generated that require modifications in capacity, productivity, quality, technology, and cultural.
-
Decision at a tactical level: Corresponds to the decisions to adjust the strategic requirement. In the face of a special or new situation, these adjustments are related to the requirements of productivity, quality, design, and technology.
-
Decision at the operational level: Corresponds to the decisions to adjust the tactical requirement. In the face of a special or new situation, these adjustments are mainly related to the standard method and times.
-
Action at the operational level: It is the application of methods, talent, and technology in the operation. This implementation is aligned with the tactical and strategic levels and is in tune with the organizational culture.

And when? issue messages through the communication channel. – Analysis of situations that seek to increase the perception, comprehension and projection capabilities of the participants. – Define and review corrective, preventive actions and improvement options in communication activities. |
|
– Define the frequency of review of the communication system. – Presentation of results regarding the goal. – Analysis of special situational patterns. – Evaluate strategic actions. |
2.2.2. Description of the Implementation Stages
-
Identify elements (products, equipment, people, facilities, services, software, etc.), variables (qualitative and quantitative), situations, and scenarios to be analyzed with management according to the guidelines established by Platts K. and Gregory M. in 1990 [40].
-
A series of meetings is established with management, based on the information obtained in the audit and historical statistics, defining the scope, objectives, goals, deadlines, resources, technology, and restrictions of the productivity improvement project, Which will have as its main tool an improvement in communication processes using technology.
-
The technology must be selected considering management requirements in terms of budget, information security, access, and features for efficient communication. This definition must be agreed upon with management.
-
Based on the statistical information, the organization chart, the information generated by the audit, and the researcher’s criteria in action, the groups must be defined. In our case, the model pre-establishes the quality, maintenance, and supervision groups, but they can establish groups such as human resources, logistics, purchasing, sales, etc. depending on the specific case.
-
Before deciding who will participate in the groups, it is important to carry out an evaluation of the human resource that helps us determine if it has any incompatibility with the project. After this, a meeting must be held with the operations management to define who will participate in the groups.
-
The objectives, goals, and deadlines for the implementation of the productivity improvement project must be transmitted to the staff, improving coordination with a communication tool in the processes. Communication norms must be established and taught to participants, establishing schedules, type of information to be transmitted, language to be used, confidentiality rules, etc.
-
The action researcher, together with the head of operations, must coordinate periodic instances of physical or remote meetings with the participants of each group, where the functioning of the coordination system and its relationship with the objectives of the productivity improvement action plan must be reviewed. In these meetings, the statistics of the previous cycle or period will be presented, the progress made regarding the goals. and the individual situations of each group will be analyzed where they will be shared with the participants of other groups to increase their level of group situational awareness.
-
The action researcher together with the operations manager must coordinate physical or remote meeting instances with management, where situational statistics, special situational patterns, performance regarding goals will be reviewed, and strategic actions will be evaluated.
2.3. Application of the Model in a Real Case
Stage 2. After observing the decision making of the operational and tactical levels, the action researcher proceeded to participate in a series of meetings with management, from where the level of awareness of the management situation could be perceived and comprehended, and thus project the company’s strategic objectives and plans.
The objectives and goals defined by management for the productivity improvement project were:
The restrictions were: not to make large investments and to minimize layoffs.
The scope of the improvement plan was defined as the manufacturing operations area, including the quality, maintenance, planning, and operations supervision departments.
In addition to the above, and before being able to intervene in operations at an operational level, management requested a series of implementations that aimed to collaborate with tactical management:
-
Redesign of production programs;
-
Identification of factors that affected the productivity of the process;
-
Establish planning rules;
-
Implement a planning module that is integrated into the company’s ERP;
-
Implement a production and inventory control module;
-
Implement the quality management and production control department.
Once the actions that strengthen the tactical level of operations have been implemented, the Action Researcher assumes the role of Production Manager and begins with the interventions. This is performed with a permanent presence in field operations, observing problems and situations in real time, comprehending how operators, supervisors, area managers, and planners decided in situations and scenarios that emerged during the operation. The period defined by management to achieve the goals was 9 months.
Stage 3. In the technology selection stage, we found various applications available, but without many inconveniences it was agreed with management to use WhatsAppMT as the communication tool for the productivity improvement project; this mainly due to its popularity, low barriers to entry, stability of operation and the multiple possibilities of issuing a message.
Stage 4. Coordination groups were established based on:
As a result, and after a review with operations management, the following communication groups were defined:
-
Quality;
-
Maintenance;
-
Supervision.
Stage 5. The decision of those who participated in each group was based on the following criteria:
-
The number of participants in each group should not be too high to facilitate agile decision-making, but not so small to avoid biased decisions;
-
Participants in each group must have technical knowledge, connection to the process in question, availability, and commitment.
Stage 6. Three initial meetings were held which had the following objectives:
-
Transmit to the participants the objectives, goals, and deadlines of the productivity improvement project, bridging the most significant gaps and using communication as a fundamental tool.
-
The head of operations, the person in charge of occupational risk prevention, and the action researcher established the basic aspects to regulate:
-
Hours of use;
-
Safe places for review and issuance of information;
-
Way (text message, audio, video or file) to issue a message depending on the situation;
-
Content and length of messages;
-
Confidentiality;
-
Recommended formats for emergency communications, coordination, suggestions and changes.
-
-
In this third meeting, the follow-up and monitoring indicators were defined, the resources (cell phones) were delivered and the communication system using mobile technology was started.
Stage 7. Meetings with project participants were established on a monthly basis, and the work plan was based on compliance with the PDCA cycle (plan, do, check, act), which was repeated during the project. The activities at each stage of the cycle were:
-
Plan: The production manager (action researcher) assumed responsibility for this stage, establishing objectives, goals, metrics, those responsible, and the execution schedule of the action plans for each cycle.
-
Do: This a stage of responsibility distributed among the participants, which seeks the rapid implementation of the defined action plans when specific situations arise.
-
Verify: The production control area must generate situational statistics and analyze the existence of situational patterns, generating a relationship with the metrics and objectives of the improvement project, evaluating the strengths and weaknesses in communication via WhatsAppMT.
-
Act: This is a stage of responsibility distributed among the participants. The aim is to make adjustments or modifications to the communication standards and implement the necessary changes or adjustments in the process.
This cycle is repeated monthly, allowing continuous monitoring of the improvement process, adjusting the plan based on the results obtained.
Stage 8. The action researcher and the operations manager scheduled monthly meetings with management, where situational statistics, special situational patterns, and performance regarding goals, objectives, and strategic action plans were reviewed in each instance, considering the company’s external and internal environment.
4. Discussion
-
Stage two: The process of analyzing the gaps and their statistics with management was delicate, since numerous complaints were generated from senior management towards operations management. These complaints were expressed in phrases such as: “Why didn’t we do it sooner?” or “Why are we only addressing this now?” During the meetings, much of the time was spent explaining the processes at a tactical and operational level to senior management, revealing important gaps and opportunities for improvement.
-
Stage three: When choosing a technology for communication in the coordination of operations in manufacturing, it is important to take into account several key aspects. These include security, reliability, latency, and cost. These elements are fundamental to guaranteeing effective and efficient communication. In addition, it is also beneficial to consider the ability to integrate with other management and control systems in real time, which can optimize coordination and improve productivity in the manufacturing environment.
-
Stage four: The groups were defined based on the functional areas, as well as the objectives and goals established by management. In our case, the factor of geographical location or other types of organization other than the functional one, such as the matrix structure, were not taken into account. These aspects are relevant especially in large companies or with resources shared between different areas.
-
Stage five: During the configuration stage of the communication groups, various factors played a fundamental role in their formation. Among them are the complementarity of skills, the role and responsibilities of the participants, as well as information flows. Identifying the talents of each participant helps with the projection of the behavior of some elements in the group, allowing for the projection and configuration of more stable groups over time.
-
Stage six: Establishing goals, standards, metrics, and formalizing the delivery of resources is crucial to demonstrating management’s commitment to the improvement plan. Incorporating these agreements in employment contracts reinforces the importance of these aspects, even though there is no current specific legislation in this regard.
-
Stage seven: During the implementation of the PDCA cycles (plan, do, check, act), considerable increases in production levels and decreases in rejections were achieved, exceeding the goals established by management. The improvement plans were driven and diminished by a series of factors, which can be seen in Table 4 and Table 5.
To the extent that senior management better perceived and understood the events that occurred in the production process, they could project with a higher level of confidence the impact of the implementation of improvement options, authorizing resources more quickly.
-
Stage eight: the periodic meetings with management at the beginning were quite complex due mainly to the low situational awareness that management had of the events and scenarios faced by the operations management and the tactical and operational areas. But as the process progressed, their learning was a valuable catalyst for change, significantly improving the quality of decision making.
5. Conclusions
In this study, a novel approach was devised, merging a qualitative model of situational awareness with the operational principles of a quantitative proportional, integral and derivative method.
We introduced innovation by establishing the concept of “levels of primary and secondary perception”, which can be managed based on the design of communication groups. Additionally, we defined cognitive work involving the visualization of a “common or special situational pattern” as a discrete event. This, in turn, facilitated comprehension, learning, and the generation of corrective and preventive action plans, which were created proportionally and integrally and applied to the process derivatively. This holistic approach considers the asymmetry that characterizes information flows in productive processes but strategically delivers a level of symmetry in communication within groups, thereby increasing levels of situational awareness in leadership, streamlining resource allocation, and consequently, improving the system’s responsiveness to deviations in process variables. The latter was achieved by designing an integrated communication system comprising operational, tactical, and strategic levels within a company.
The group situational awareness model proposed in this document and implemented in an industrial process obtained a success story by efficiently coordinating the information provided by both the external and internal environment to the process, generating a virtuous circle of information, which allowed for achieving a very relevant level of productivity improvement and reduction in the rejected (waste).
The action researcher methodology was perfectly adjusted to the situation under the study of participating directly with the teams, being mainly a facilitating agent and main source of theoretical knowledge applicable to process management.
The WhatsappMT tool efficiently met the required needs, despite being a generic and not very specific application, it managed to be useful in all the situations coordinated.
Real-time operations management is a challenge for directors and the entire operations team, but at the same time, it provides great benefits by more directly connecting the operation with the strategy.
The impact of our work aligns with several Sustainable Development Goals (SDGs). We contributed to SDG 8 (Decent Work and Economic Growth) by enhancing efficiency in production processes and to SDG 9 (Industry, Innovation, and Infrastructure) by introducing innovations in the management of these processes. Additionally, we addressed SDG 12 (Responsible Consumption and Production) by reducing the production of defective products and waste, and SDG 13 (Climate Action) by halting production in case of failures, promoting more sustainable practices. Our focus on collaboration between management and the Gemba supports SDG 17 (Partnerships for the Goals), consolidating a commitment to sustainable development.
This hypothesis finds support in the results obtained after implementing our model to an industrial process. The swift allocation of resources and timely halting of production in the face of failures have contributed to the sustainability of this process. The agility in decision making after establishing the communication system has shown to increase productivity through immediate actions, and the significant reduction in the production of defective products and waste confirms the effectiveness of these measures.
