    • Companies can improve their sustainability performance through reducing risk and costs of scarce resources, developing more sustainable products and processes, and targeting environmental and social needs.
    • Sustainable value creation increases the economic, social, and environmental value of goods, services, or the overall business.

    Life Cycle Thinking (LCT)

    • LCT focuses on the environmental, social, and economic impacts of a product over its entire life cycle, considering the holistic perspective and interdependency.
    • It encourages a shift in mindset from a traditional focus on production to inclusive consideration of all life cycle phases: from raw material extraction to end-of-life disposal.
    • LCT aims to identify opportunities and risks in product or service design, focusing on resource consumption reduction and performance improvement.

    Life Cycle Management (LCM)

    • It involves practices for targeting, organizing, analyzing, and managing product or service-related information and activities to enhance continuous improvement throughout the entire life cycle.
    • LCM integrates product or service sustainability into company strategy and planning, product design and development, purchasing decisions, and communication policies.

    Life Cycle Assessment (LCA)

    • LCA is a quantitative method for assessing the environmental impacts associated with a product's life cycle, encompassing product, process, and service.
    • It serves as a decision-making tool for sustainability management by providing a scientific and comprehensive framework for evaluating diverse impact categories, including climate change, resource depletion, air acidification, and biodiversity loss.

    • It is a decision-making tool for sustainability management, allowing for comparisons between different options.
    • LCA is scientifically based, comprehensive, standardized by ISO 14040 series, and helps avoid pollution shifting.

    LCA Methodology

    • LCA follows a four-step methodology:
      • Goal and Scope Definition: Defining the purpose and boundaries of the LCA.
      • Life Cycle Inventory (LCI): Quantifying resource use and environmental emissions in each stage.
      • Impact Assessment: Evaluating the environmental effects of resource use and emissions.
      • Interpretation: Analyzing and reporting the results, drawing conclusions, and providing recommendations.

    Purpose of LCA

    • LCA is used for:
      • Product and process development (R&D).
      • Marketing purposes (Eco-labelling).
      • Development of environmental performance indicators.
      • Selecting suppliers or subcontractors.
      • Strategic planning.

    Life Cycle Analysis Step 1: Goal and Scope

    • An LCA is a tool used to assess the environmental impacts of a product over its entire lifecycle.

    • The first step in an LCA is to define the Goal and Scope of the study.

    • To define the goal of the study, answer the question, "Why?"

    • Examples of reasons to perform an LCA include:

      • Assessing environmental and health impacts
      • Improving design and procurement decisions
      • Meeting communication needs, achieving compliance, and making better policies
      • Identifying cost savings and enhancing brand value

    • The next question to answer is "Who?"

    • The answer helps to identify the target audience for the study.

    • Examples of target audiences include internal teams, such as design or engineering, or external stakeholders, such as suppliers, the CEO, and the public.

    • To define what will be analyzed, the "What?" question must be answered.

    • This involves defining a product's function and functional unit (FU).

    • A product's function is a description of its purpose or the purpose of its components.

    • A functional unit is a quantified performance of a system of products that is used as the reference unit in the LCA study.

    • Examples of functions include "sit," "move quick and easily," and "store belongings."

    • Examples of functional units include "1 kg of packaging material" or "10,000 hours of operation."

    • To define the boundaries of the study, the "Where?" question must be answered.

    • The answer defines the system boundaries, which separate the studied product system from the surrounding economy (technosphere) and the environment (ecosphere).

    • System boundaries determine the unit processes for which environmental impacts should be quantified.

    • Cradle-to-gate boundaries include the stages from raw material extraction to factory gate.

    • Cradle-to-grave boundaries include the stages from raw material extraction to the end of life of the product.

    • Cradle-to-cradle boundaries include the stages from raw material extraction to the reuse or recycling of the product.

    • Defining the system boundaries includes defining the level of scrutiny or the cut-off rules.

    • Cut-off rules help define the boundaries of the study by considering factors such as:

      • Physical measure with weight (% total mass)
      • Cost or revenue contribution (% total cost)
      • Environmental aspects contribution

    • The location of the study is important.

    • For example, the location for the manufacturing of the product, the location where the product is used.

    • Example: A study on hand dryers might be conducted in China if the product is manufactured in China and used in the United States.

    Life Cycle Analysis: Step 1 - Goal and Scope

    • The goal of the Life Cycle Analysis (LCA) should be defined by asking WHY, WHO, WHAT, WHERE?
    • WHY: Clearly identify the reason for the LCA. Examples include:
      • Assessing environmental impacts (e.g., health impacts)
      • Improving design decisions
      • Making better procurement choices
      • Meeting communication needs
      • Achieving compliance with regulations
      • Developing effective policies
      • Identifying cost savings
      • Enhancing brand value for competitive differentiation
    • WHO: Identify the target audience for the LCA. It could be for internal use, specific teams (design, engineering), suppliers, stakeholders, the public, etc.
    • WHAT: Determine the product/process being analyzed and define its function. This includes:
      • Basic functions: Core actions the product performs.
      • Additional functions: Additional capabilities beyond the core function.
      • Functional unit (FU): Quantified performance of the system.
      • Considerations when defining the FU:
        • Avoid assuming the same physical quantity equals the same function.
        • Avoid being overly restrictive when defining the FU.
        • Use technical standards or legal requirements correctly.
    • WHERE: Establish the system boundaries:
      • Cradle to gate: Focuses on production up to the factory gate.
      • Cradle to grave: Includes production, use, and end-of-life phases.
      • Cradle to cradle: Considers material reuse and recycling.
      • Cut-off rules: Used to determine which components are included in the analysis based on:
        • Physical measure: Weight percentage of the total mass.
        • Cost or revenue contribution: Percentage of the total cost.
        • Environmental aspects contribution: Impact on the environment.
      • Location: Identify the primary region of focus for the study, including manufacturing and use locations.

    Goal and Scope

    • The goal and scope of a life cycle assessment (LCA) is defined by answering four questions: Why, Who, What, and Where.
    • The "Why" question helps define the specific objectives of the study and should identify specific decisions relating to sustainability that the LCA will support.
    • These decisions could include assessing environmental and health impacts, improving design choices, making informed procurement decisions, meeting communication needs, achieving compliance, enhancing policy, identifying cost savings, or enhancing brand value for competitive differentiation.
    • The "Who" question establishes the target audience for the LCA results.
    • The target audience could include internal teams like design or engineering, external parties like suppliers or the CEO, and the general public.
    • The "What" question determines the analysis' scope.
    • LCA requires a fair basis for comparison, focusing on the product's function.
    • Function is described as an action explaining the product's main purpose or the purpose of individual components.
    • A simple way to describe function is through a verb followed by complements.
    • Two levels of function are considered: Basic functions and additional functions.
    • Basic functions are the core actions the product performs.
    • Additional functions are those that enhance the user experience.
    • The "What" question also includes defining the functional unit (FU), which is the quantified performance of the product system used as a reference point for comparison.
    • The FU should relate to a quantity of service delivered rather than a physical quantity of the product.
    • The "Where" question focuses on the system boundaries.
    • System boundaries define the interactions between the studied product system and the surrounding economy (technosphere) and the environment (ecosphere).
    • They determine which unit processes will be considered for environmental impact quantification.
    • There are two main types of flows within a system: Elementary flows and non-elementary flows.
    • Elementary flows are resources directly taken from or emissions released to the environment.
    • Non-elementary flows involve intermediary materials, components, products, co-products, or wastes exchanged between actors in the system.
    • System boundaries also define the life cycle phases considered (Cradle to Gate, Cradle to Grave, Cradle to Cradle), the level of scrutiny in the study, based on physical measure, cost, and environmental contribution, and the location of the study.

    Common Mistakes in Defining a Functional Unit

    • Assuming the same physical quantity of product equals the same function.
    • Being overly restrictive in defining the functional unit.
    • Incorrectly using technical standards or legal requirements.

    Cut-off Rules

    • Cut-off rules are used to establish boundaries and define criteria for excluding certain processes or components from the LCA scope.
    • Common criteria include weight percentage (% total mass), cost or revenue contribution (% total cost), and environmental aspect contribution.

    Life Cycle Inventories (LCI)

    • An LCI is a quantitative list of both elementary and secondary flows.
    • Elementary flows are inputs and outputs to the environment.
    • Secondary flows are intermediate and final products or waste between actors in a system.
    • An LCI is built on a process diagram.
    • An LCI must consider previously established goals and scope definitions.

    Impact Assessment (LCIA)

    • The objective of the impact assessment is to understand and evaluate the impacts of the system under study.
    • Choice of impact assessment methodology and database is crucial for the scope of the analysis.
    • Impact categories can be expressed as both midpoint and endpoint categories.
    • Different quantified flows must be reconciled into impact categories through classification, characterization, normalization and weighting.
    • Characterization factors are used to convert the quantities of flows into equivalents of a reference substance.
    • Normalization provides a relative impact comparison through an exposure of reference.
    • Weighting sets the importance of different impacts and combines them into a single impact score.

    Interpretation and Conclusions

    • The objective of the interpretation stage is to analyze the results, proceed with sensitivity and uncertainty analyses, and formulate recommendations.
    • Sensitivity analysis determines the variation in an input parameter or choice that produces a change in results.
    • Uncertainty analysis accounts for uncertainty in baseline assumptions or in bill of activities data.
    • A decision tree is the combined results of sensitivity and uncertainty analyses, which can help focus improvement efforts.

    Main Limitations

    • Many decisions are made during all phases of an LCA, such as:
      • Functional unit and scope
      • Impact categories
      • Allocations
      • Weighting
      • Cut-offs
    • Data and model quality influences the usefulness of an LCA.
    • Parameters, scenarios, and model limitations can all affect the conclusiveness of an LCA.
    • LCA can't directly determine if a product or service is sustainable, as it only provides environmental impact information.
    • Environmental Life Cycle Costing (eLCC) and Social Life Cycle Analysis (S-LCA) are used to address this limitations.
    • S-LCA assesses the social impacts of products and services.

    Challenges for LCA Development

    • Lack of awareness, perceived benefits, knowledge, resources, incentives, and complexity are all factors that can hinder the adoption of LCA tools by SMEs.

    Life Cycle Inventories (LCI)

    • LCI is a list of quantified elementary flows (inputs, resources, and outputs, emissions) and secondary flows (intermediate and final products or waste between actors) needed to fulfill the Functional Unit (FU).
    • LCI is based on a process diagram and done with respect to the goals and scope definition.

    Impact Assessment (LCIA)

    • Impact Assessment is a crucial step in LCA, aiming to understand and evaluate the magnitude and significance of potential environmental impacts of the studied system.
    • The choice of database and impact assessment method depends on factors such as:
    • Impact categories (midpoint and endpoint)
    • Product and/or process, the industry
    • Specific environmental regulation, ecolabel, or ecoprofile
    • The company's environmental agenda
    • Consistency with other studies

    Impact Categories

    • Impact categories classify environmental impacts by their influence on the environment.
    • Midpoint Categories are the immediate impacts of a product or process.
    • Example: Ozone depletion, Global Warming, Acidification, Eutrophication.
    • Endpoint Categories measure the overall effects on human health and the environment.
    • Example: Human health, ecosystem quality, resource depletion.

    Three Main Steps for Reconciling Flow Quantities for Impact Assessment

    • Classification: Flow quantities from the LCI are linked to their corresponding Impact Categories, with one flow potentially operating on different impacts, and multiple flows potentially acting on the same impact category.
    • Characterization: Flow quantities are expressed in equivalent quantities of a reference substance based on a characterization factor.
    • Normalization and Weighting:
      • Normalization: Uses a reference exposure (average annual impact) to create a relative impact.
      • Weighting: A relative and subjective importance is assigned to each impact result, allowing the different scores to be added for a single score, expressed in "points" (Pt).

    Interpretation and Conclusion

    • Analyze the results (main contributors of the analyzed impacts).
    • Conduct sensitivity and uncertainty analyses.
    • Make recommendations.
    • Sensitivity Analysis: Determines how much a variation in an input parameter or choice affects the results.
    • Uncertainty Analysis: Relates to baseline assumptions (multi-parameter variations) and/or bill of activities data (estimated by software). It allows for quantifying and improving the precision of a study and the robustness of its conclusions.

    Limitations of LCA

    • Decision Making: Decisions made during an LCA can influence its outcomes.
    • Data and Model Quality: Uncertainties exist in data quality, gaps, unrepresentativeness, and model limitations.
    • LCA ≠ Sustainability: LCA alone cannot tell us if a product/service is sustainable.
    • S-LCA and eLCC: Social Life Cycle Analysis (S-LCA) and Environmental Life Cycle Costing (eLCC) methods can help address the limitations of LCA, supporting a more comprehensive sustainability assessment.

    Main Challenges To LCA Development

    • Lack of awareness of sustainability issues.
    • Absence of perceived benefits.
    • Lack of knowledge and expertise on sustainability issues.
    • Lack of human and financial resources.
    • Insufficient external drivers and incentives.
    • Challenges in changing workplace routines.
    • Unsuitability of formal management tools to fit the often informal and flexible SME structure.
    • Complexity of tools.

    Life Cycle Assessment (LCA)

    • LCA is a tool used to analyze the overall environmental impact of a product or service throughout its life cycle.
    • The goal of LCA is to identify areas where environmental impact is most significant and to develop solutions for improvement.
    • It comprises a structured framework to evaluate the environmental impacts of a product or service throughout its life cycle.
    • The LCA framework considers all stages of a product or service’s life cycle such as:
      • Raw materials: acquiring raw materials from natural sources.
      • Fabrication: manufacturing or production of a product.
      • Distribution: transportation and handling of a product from factory to market.
      • Use: consumption of the product by the consumer.
      • End of life: disposal, recycling, or reuse at the end of the product's life cycle.

    Pollution Shifting

    • Pollution Shifting, also known as “pollution transfer”, is a phenomenon where environmental pollution is transferred from one stage of a product's life cycle to another or from one geographic location to another.
    • Impact on the environment may shift due to product life-cycle transition.
    • Impact on the environment may shift due to product geographic location transition.

    LCA Software Tools

    • Several software tools are available specifically designed to assist with LCA analysis.
      • SimaPro
      • Gabi
      • OpenLCA
      • ecoinvent- a database of environmental data
      • USDA
      • Ecochain

    Step 1: Goal and Scope

    • Defining the goal and scope is a critical step in the LCA process.
    • It helps to ensure that the study is focused and relevant to the intended use of the results.
    • Four main questions to consider when defining the goal and scope of an LCA:
      • Why: Why is the LCA being conducted?
      • Who: Who is the target audience for the LCA results?
      • What: What is the specific system being evaluated?
      • Where: Where are the boundaries of the system defined?

    Defining the ‘Why’

    • Defining the ‘Why’ helps in understanding the purpose of the LCA study.
    • Objectives of the LCA could include:
      • To assess environmental and health impacts.
      • To improve design decisions.
      • To make better procurement decisions.
      • To meet communication needs.
      • To achieve compliance.
      • To make better policies.
      • To identify cost savings.
      • To enhance brand value for competitive differentiation.
      • To identify environmental hotspots (areas where environmental impacts are most significant).
      • To support decision-making.

    Defining the ‘Who’

    • Defining the ‘Who’ is important for understanding how the results of the LCA will be used.
    • The target audience can include:
      • Internal teams, such as design or engineering teams
      • Suppliers
      • CEOs
      • The public

    Defining the ‘What’

    • Define the system boundaries of the LCA study.
    • System boundaries determine which activities and processes are included in the analysis.
    • This could help clarify the specific product or system being evaluated.
    • The system can be defined as a product, process, or service. For example, the LCA of a product could include the environmental impacts of raw material extraction, manufacturing, assembly, transportation, use, and disposal.

    Defining the ‘Where’

    • Defining the ‘Where’ is important for understanding the geographic scope of the LCA study.
    • It determines the location of the activities and processes being evaluated.
    • Geographic scope could include:
      • Specific regions or countries
      • Transportation routes
      • Specific locations within a manufacturing facility.

    Cradle to Grave vs. Cradle to Cradle

    • Cradle to Grave analysis is a life cycle assessment (LCA) that considers all stages of a product's life, from its creation (cradle) to its disposal (grave).
    • Cradle to Cradle analysis is a life cycle assessment (LCA) that considers the product's ability to be recycled or reused at the end of its life.

    Cut-Off Rules

    • Cut-off rules are used to determine which aspects of an LCA study will be included or excluded.
    • These rules are based on factors such as:
      • Physical measure (weight percentage)
      • Cost or revenue contribution (percentage)
      • Environmental aspects contribution (percentage).

    Step 3: Impact Assessment

    • Impact assessment is the stage of LCA where the environmental impacts of a product or service are quantified and analyzed.
    • It uses impact assessment methods to evaluate the environmental impacts of a product or service.
    • Some impact assessment methods include:
      • Global warming potential (GWP)
      • Ozone depletion potential (ODP)
      • Acidification potential (AP)
      • Eutrophication potential (EP)
      • Water depletion potential (WDP)
    • It identifies the most significant environmental impacts associated with the product or service.

    Step 4 : Interpretation and Conclusion

    • The final step in the LCA is to interpret the findings.
    • The goal of interpretation is to communicate the results of the LCA in a clear and concise manner.
    • This can be done through:
      • Summarizing the findings
      • Identifying key takeaways
      • Identifying areas for improvement.
      • Recommendations for future work.

    Sensitivity Analysis

    • Sensitivity analysis is a statistical method used to determine how changes in input parameters impact the results of an LCA.
    • It helps to quantify the uncertainty associated with the model results.
    • It helps to identify the key drivers of the environmental impacts.
    • It helps to understand how sensitive the model is to changes in input data.

    Uncertainty Analysis

    • Uncertainty analysis is a statistical method used to quantify the uncertainty associated with the results of an LCA.
    • It incorporates uncertainties in input data, model parameters, and impact assessment methods.
    • It helps to understand the range of possible outcomes for the LCA.
    • It helps to understand the robustness of the results.

    Environmental Life Cycle Costing ( eLCC)

    • Environmental Life Cycle Costing (eLCC) is a method for analyzing the costs and benefits of a product or service throughout its life cycle.
    • It considers both environmental and economic factors.
    • It can be used to make informed decisions about the sustainability of a product or service.

    Social Life Cycle Analysis (S-LCA)

    • Social Life Cycle Analysis (S-LCA) is a method for analyzing the social impacts of a product or service throughout its life cycle.
    • It considers a wide range of social factors such as:
      • Human rights
      • Labor conditions
      • Community well-being.
    • It can be used to make informed decisions about the social sustainability of a product or service.

    Limitations of LCA:

    • LCA is a powerful tool for assessing the environmental impacts of a product or service but it has limitations.
    • It is not a perfect tool.
    • LCA does not account for all environmental factors.
    • LCA does not assess the social and economic impacts of products.
    • LCA does not account for the complex interactions between environmental impacts and social factors.

    Recommendation:

    • LCA can be a valuable tool for making informed decisions about the sustainability of a product or service.
    • However, it is important to be aware of the limitations of LCA.
    • It is important to use LCA in conjunction with other methodologies, such as eLCC and s-LCA.

    Life Cycle Thinking (LCT)

    • LCT focuses on environmental, social, and economic impacts of a product across its entire life cycle
    • LCT considers the impacts beyond manufacturing processes, including design, production, use, and end-of-life
    • LCT considers the global impact of a product system to prevent pollution transfer
    • Sustainable development is both the origin and the objective of LCT

    From LCT to Life Cycle Assessment (LCA)

    • LCA is a specific tool for analyzing resource consumption and environmental impacts over a product's life cycle
    • Data and models are used to measure and analyze environmental impacts, while LCA provides a structured approach for decision-making

    LCT to LCA Mindset

    • LCT is a broader concept focusing on thinking about the entire life cycle
    • LCA is a tool for evaluating impacts within the life cycle

    LCA – Step 1: Goal & Scope

    • Goal and scope definition is crucial for conducting a meaningful LCA study.
    • Four key questions are used to define and analyze the goal and scope: Why, Who, What, Where.

    Why

    • LCA is used to assess, improve, or inform decisions about different factors.
    • Examples include:
      • Assess environmental impacts
      • Improve design decisions
      • Make better procurement decisions
      • Meet communications needs
      • Achieve compliance
      • Identify cost savings
      • Enhance brand value

    Who

    • Identifying the target audience determines how the results of the study will be used.
    • The target audience could be:
      • Internal teams
      • Suppliers
      • Public
      • Policymakers

    What

    • The "what" of an LCA defines what will be analyzed, this requires defining the functional unit of the product.
    • Functional unit: a quantitative measure of the product's service or function. The focus is on the service provided, not the physical product.
    • Defining the functional unit should avoid following these mistakes:
      • Assuming that the same physical quantity of a product equals the same function
      • Being overly restrictive: Not defining the functional unit broadly enough
      • Incorrectly applying technical standards or legal requirements

    Where

    • System boundaries define the product system's interactions with the environment and the surrounding economy.
    • This determines which unit processes are included in the analysis, and which impacts will be quantified.
    • System boundaries are crucial for understanding the flow of materials and energy within the product system.
    • Elementary flows: directly emitted to the environment (resources used or pollution emitted in air, water, or soil)
      • Non-elementary flows: intermediary materials, components, products, co-products, or wastes exchanged between actors

    LCA – Step 3: Impact Assessment

    • Impacts of different life cycle stages (e.g., material extraction, manufacturing, use, end-of-life) are evaluated on various environmental categories (e.g., climate change, water pollution, resource depletion)

    LCA – Step 4: Interpretation & Conclusion

    • Interpretation involves analyzing the results and identifying key contributors to the impacts.
    • Sensitivity analysis: examines how variations in input parameters affect the results.
    • Uncertainty analysis: quantifies the precision and robustness of the conclusions by considering the uncertainty in baseline assumptions and data.
    • Both sensitivity and uncertainty analysis play crucial roles in ensuring the reliability and credibility of the LCA findings.
    • Interpretation and conclusion aim to provide recommendations based on the findings and their implications for decision-making.

    Two levels of LCA

    • Products (goods and services) level
    • Corporate Level: Organizational LCA (O-LCA)

    LCA & LCT

    • Life Cycle Thinking (LCT) is an approach that includes the environmental, social, and economic impacts of a product throughout its entire life cycle.
    • Life Cycle Assessment (LCA) is a standardized method for assessing the environmental impacts of a product or process, which can be used to support LCT.

    LCA - Four Main Steps

    • Goal Definition & Scope
    • Inventory Analysis
    • Impact Assessment
    • Interpretation & Conclusion

    LCA - Goal and Scope

    • Function: a description of the product's purpose, expressed as a verb with complements
    • Functional Unit: a quantifiable performance of a system of products used as the reference unit in the LCA study
    • System Boundaries: determine the processes for quantifying environmental impacts

    Uncertainty in LCA

    • Parameter Uncertainty: data quality, gaps, unrepresentative data
    • Scenario Uncertainty: managed through sensitivity and uncertainty analyses
    • Model Uncertainty: insufficient knowledge of the system's mechanisms, steady-state assumptions

    LCA Limitations

    • LCA can be challenging due to the complexity of data collection, especially for specific sectors like the IT sector.
    • LCA cannot determine if a product or service is sustainable, but it can provide valuable insights on environmental impacts that can inform decision-making.

    Types of Brands

    • National brands are owned and initiated by a national manufacturer or by a company that provides services.
    • Retailer brands are known as private brand, store brand, dealer brand, or private label.
    • Generics are products that do not carry a company identity.

    What is a Brand?

    • A brand is a "name, term, sign, symbol, or design, or a combination of them, intended to identify the goods and services of one seller or group of sellers and to differentiate them from those of competition" (American Marketing Association).
    • A brand is "more than a product, because it can have dimensions that differentiate it in some way from other products designed to satisfy the same need" (Kevin Lane Keller).

    Brand Elements

    • Brand Elements are a brand’s physical manifestation.
    • These elements include:
      • Brand Names & URLs
      • Packaging & Signage
      • Logos & Symbols
      • Slogans and Jingles
      • Characters

    Branding Significance

    • Branding helps marketers increase brand awareness and create unique associations with a brand.

    Brand Imagery

    • Brand imagery refers to how a product or service attempts to meet customer’s psychological or social needs.
    • Key factors influencing brand imagery:
      • User Profiles
      • Personality and Values
      • Purchase and Usage Situations
      • Physical
      • Ideas & Causes
      • Good & Service
      • Place
      • Retail Outlet
      • Sports
      • People
      • Organization

    Blind Beer Test Experiment

    • Participants in a blind beer test were unable to recognize their usual beers.
    • When labels were present, the perceived quality of the beers increased significantly.
    • This experiment demonstrates that brands can influence the perception of taste and quality.

    Brand as a Sign of Recognition

    • A brand acts as a sign of recognition, identification, and quality.
    • Brands reduce risk for consumers by providing a trusted indicator of quality.
    • Brands also reduce search costs by providing a familiar point of reference.
    • Brands can be physical manifestations, with brand signs serving as a representation of a product or service.
