    • Ethical problems stem from the end product, the development process, and human interactions.
    • Obligations relevant to the software professional involve: Self, Society/Public, Colleagues, Client, Employer, Product, Profession

    Ethical Behaviour in a Professional Setting

    • Ethical behaviour refers to how an individual or organization makes decisions and interacts with stakeholders.
    • Aligning decisions, actions, and interactions with moral and professional principles is essential.
    • These principles support laws, regulations, and the organization's culture and values.

    Technical & Ethical Issues in Systems Analysis/Software Engineering

    • Project managers might cut short requirement definition phases to catch up on time.
    • Developers may base testing on descriptions of code rather than requirements.
    • Misrepresenting, incomplete requirement specification leads to difficulties in meeting user needs, causing potential issues such as product unusability and contracts being cancelled.
    • Developers' behaviour influenced by personal interests can become ethically questionable.

    Technical and Ethical Issues with System Analyst/Software Engineer

    • Misrepresentation of Requirements in Software Specification: Failing to capture or accurately reflect user requirements to meet deadlines or cut costs can result in systems failing to meet user needs.
    • Software Design: Difficulty translating domain expertise into software requirements.
    • Extreme Pressure to Skip Critical Steps: Skipping essential software development lifecycle (SDLC) steps due to time constraints leads to poor-quality code. This can cause system failures, vulnerabilities, and potential harm to users.
    • Insufficient/Incompetent Staff: Lack of project management, bad planning/estimation, or insufficient senior staff can lead to deadly consequences for systems.
    • Use of Unauthorized Software: Using illegal or uncredited open-source code violates intellectual property laws and undermines professional ethics.
    • Conflicts of Interest: Recommending solutions that benefit personal or third-party interests undermines the integrity of the analyst and decision-making process
    • Handling User Data: Collecting, storing, or using user data without consent violates privacy rights and legal regulations. Unauthorized disclosure compromises public welfare and leads to violations, penalties, and damage to reputations
    • Security and Privacy: Failing to implement appropriate safety measures exposes users and organizations to cyberattacks, data breaches, and financial damage.
    • Bias in Decision-Making: Prioritizing stakeholders' needs based on personal biases leads to biased solutions and harms trust in fairness.
    • Red Lies/Over-Promising and Under-Delivering: Statements about projects or products falsely suggesting timely delivery undermines stakeholder relationships and trust.
    • Inadequate Risk Management: Ignoring or underestimating potential project risks.
    • Inadequate Test Coverage: Skipping necessary test phases due to resources or time constraints.
    • Automation Limitations: Over-reliance on automated tools, which may have limitations, can reveal missed or overlooked defects.
    • Reporting Bugs: Failing to report all defects, especially critical ones, due to time constraints, risks system unreliability and user satisfaction
    • Biased testing: Biased testing methodologies lead to problems in finding all system failures.
    • Security and Privacy concerns: Inadequate or ignoring user data sensitive measures can lead to cyberattacks, data breaches, and financial loss.
    • Misrepresenting or Falsifying Test Results: Altering or fabricating test reports to show the system passes requirements.

    Development of Safety Critical Systems

    • Systems whose failure may cause injury or death are called Safety-Critical Systems.

    • Developing such systems requires strong adherence to the Software Development Process, with thorough documentation and vigilance

    • Developers must work closely with safety and system engineers, using logging and monitoring to track hazards during the project.

    • Risk Analysis: Formal risk analysis is essential in safety-critical system design, building, and operation. A formal risk analysis should take account of what can go wrong, the likelihood/probability of occurrences, consequences, and how risks may be resolved or mitigated.

    Scenario No. 2: Professional Judgment

    • A quality control software engineer suspects issues with flight control software in an experimental fighter jet.
    • The engineer faces pressure from employers to sign off on the software despite concerns about sufficient testing.
    • Decision-making in this context requires professional judgment and ethical decision-making.

    Development of Safety-Critical Systems

    • Redundancy: Software should employ multiple interchangeable components for a single function.
    • N-version programming: Multiple independently-developed versions of the software can verify functionality to ensure reliability in safety-critical systems.

    Following Integrity and Ethics

    • Integrity and ethical behaviour are vital for analyst/engineer success.
    • Confidentiality/secrecy of client corporate and employee information is a major component
    • Analysts/engineers must uphold high ethical standards regarding private proprietary information.
    • Follow-through, open communication regarding project setbacks, recognizing strengths and weaknesses are essential for ethical work.

    Sources of Ethical Guidance

    Role of a System Administrator

    • Responsible for setting up and maintaining system and server.
    • Includes user administration and system performance monitoring
    • Implementing and maintaining security policies (including backup)

    Ethical Issues with System Administrators

    • Confidentiality: Handling sensitive organizational data like trade secrets and customer information without adequate safeguards is ethically problematic
    • Security and Privacy: Failure to implement proper security measures exposes users to risks like data breaches.
    • Invasion of Privacy: Monitoring employee web activity and emails can raise privacy concerns. Employee contracts should specify parameters.
    • Equality in Reporting: Policies should be transparent/equal in reporting infractions.
    • Sensitive Information: Using knowledge gained from previous employment for personal gain without proper ethical/legal guidance.
    • Whistle-Blower Situations: Torn between reporting potential illegal/unethical activities and job security.
    • Compromising Security: Cutting security measures at a client's request despite evidence that sensitive data will be compromised.
    • Consultation Fees: Playing on clients' fears of threats to their IT infrastructure to increase fees.
    • The Slippery Slope: A seemingly minor unethical action can escalate into more severe actions.

    Ethical Policies

    • Informed Consent: Key component to ethical policy, where users understand the rules and system operations.

    User Code of Conduct

    • Each organization needs written guidelines for acceptable computing systems use
    • Guidelines specify acceptable personal use vs forbidden activities.

    Privileged Access Code of Conduct

    • Users with privileged access need to acknowledge the need to use this access responsibly.
    • Limitations on the types of activities that can be done with privileged access are needed.

    Building a Security Culture

    • Information security must be treated as a corporate culture.
    • Employees are expected to be security conscious to support proper security measures and systems.
    • Administrators need to adhere to an ethical code.
