A stakeholder is an individual, group, or organization that has an interest or concern in a particular project, company, or system Stakeholders can have various roles and levels of influence, and they can be both internal and external to the organization (Landau, 2022) Figure 1: Stakeholders (Landau, 2022) Page of 72 Internal stakeholders typically include individuals or groups within the organization, such as employees, managers, shareholders, and board members They have a direct connection to the project or organization and are directly affected by its outcomes External stakeholders, on the other hand, are individuals or groups outside the organization who can be impacted by its actions or decisions They may include customers, suppliers, government agencies, local communities, investors, and advocacy groups These stakeholders often have indirect relationships with the organization but can still significantly influence its operations and success Stakeholders have different interests, needs, and expectations, and it is important for organizations to identify and engage with them effectively By considering stakeholder perspectives and involving them in decision-making processes, organizations can manage their interests, mitigate risks, and build positive relationships to achieve their goals Effective stakeholder management is crucial for ensuring transparency, accountability, and long-term sustainability (Landau, 2022) 1.2 Types of stakeholders Stakeholders can be classified into various types based on their relationship to an organization or project Here

organization They have an interest in maintaining a good relationship with the organization and may be affected by its decisions or performance • Shareholders/Investors: Shareholders or investors hold ownership stakes in the organization and have a financial interest in its success They may include individual investors, institutional investors, or venture capitalists Shareholders often expect a return on their investment and may influence the organization's strategic decisions • Employees: Employees are crucial stakeholders who work for the organization They have a direct interest in job security, fair compensation, a positive work environment, and opportunities for career growth Engaging and satisfying employees is important for organizational success • Government and Regulatory

decision-making processes alongside other board members They possess the ability to influence decisions and bring forth new ideas, sometimes exerting pressure on management to comply Moreover,
