• have an active interest in the system because they'll actually use it or are directly involved in processes that the system will change;
• must manage, introduce, operate, or maintain the system after its deployment;
• are involved in developing the system as an architect, developer, tester, quality engineer, or project manager;
• are responsible for the business or process that the system supports or automates;
• have a financial interest (for example, they've ordered the system, paid for it, or are responsible for its sale);
• constrain the system as regulators; or
• are negatively affected by the system (so-called negative stakeholders).
• If neglect might kill the project or render the system useless, the stakeholder's role is critical.
• If neglect would have a significant negative impact on the system, the stakeholder has a major role.
• If neglect would have marginal impact on the system, the stakeholder's role is minor.
