This scenario presents a professional challenge because it requires balancing the need for effective community engagement with the ethical imperative of ensuring that health promotion messages are accessible, understandable, and do not inadvertently exclude or disadvantage specific groups within the community. Public health professionals must navigate diverse communication channels and literacy levels, ensuring that information is not only disseminated but also comprehended and acted upon. Careful judgment is required to select methods that are inclusive and respectful of community diversity. The best approach involves a multi-faceted strategy that prioritises co-design and uses a range of accessible communication methods. This approach is correct because it aligns with the principles of ethical health promotion, which advocate for empowering communities and ensuring equitable access to health information. Specifically, the Health and Social Care Act 2012 places a duty on local authorities and the NHS to reduce health inequalities, which necessitates engaging with communities in ways that are sensitive to their needs and circumstances. The Public Health Outcomes Framework also emphasizes the importance of community engagement and reducing inequalities. By involving community members in the design of health promotion materials and utilising diverse formats (e.g., visual aids, local languages, community champions), this approach ensures that messages are relevant, culturally appropriate, and reach a wider audience, thereby promoting health equity. An approach that relies solely on digital platforms and written materials is professionally unacceptable. This fails to acknowledge the digital divide and varying literacy levels within the community, potentially excluding older adults, individuals with lower socioeconomic status, or those with limited English proficiency. This contravention of the duty to reduce health inequalities, as mandated by the Health and Social Care Act 2012, is a significant ethical and regulatory failure. Another professionally unacceptable approach is to use a single, standardised communication method without prior community consultation. This demonstrates a lack of understanding of community diversity and can lead to messages that are irrelevant, culturally insensitive, or even offensive to certain groups. Such an approach neglects the principles of participatory health promotion and can undermine trust between public health professionals and the community. Finally, an approach that prioritises speed and cost-effectiveness over inclusivity and accessibility is ethically flawed. While efficiency is important, it must not come at the expense of ensuring that health promotion efforts are equitable and reach all segments of the population. This can lead to a widening of health inequalities, directly contradicting the core objectives of public health. Professionals should employ a decision-making framework that begins with a thorough community needs assessment, including an analysis of communication preferences and barriers. This should be followed by a co-design process involving diverse community representatives. The selection of communication methods should then be guided by principles of accessibility, inclusivity, cultural appropriateness, and evidence of effectiveness in reaching target populations, always with a view to reducing health inequalities.

This scenario presents a professional challenge because it requires balancing the need for timely public health intervention with the ethical imperative of respecting individual privacy and data protection principles. The rapid dissemination of potentially sensitive health information, even with good intentions, carries significant risks of stigmatisation, discrimination, and erosion of public trust in health services. Careful judgment is required to ensure that public health goals are pursued through means that are both effective and legally compliant. The best approach involves a multi-faceted strategy that prioritises anonymisation and aggregation of data before any public dissemination. This includes working collaboratively with data custodians to extract only the necessary information, ensuring that no individual can be identified, and presenting findings in a way that highlights population-level trends rather than individual cases. This aligns with the principles of the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, which mandate data minimisation, purpose limitation, and the protection of individuals’ rights. Ethical guidelines for public health professionals also strongly advocate for privacy-preserving methods. An approach that involves directly sharing anonymised but potentially re-identifiable case details with local community groups without a clear data sharing agreement or explicit consent is professionally unacceptable. This fails to adequately protect individuals’ privacy and could lead to breaches of UK GDPR and the Data Protection Act 2018. It also risks creating a climate of fear and distrust within the community, undermining future public health efforts. Another professionally unacceptable approach is to delay all public communication until a comprehensive, individual-level risk assessment for every single case has been completed. While thoroughness is important, this approach prioritises an unrealistic level of detail over the urgent need to inform the public about potential risks and preventative measures. This can lead to a failure to act in a timely manner, potentially exacerbating the public health issue, and may not be proportionate to the actual public health risk, failing to adhere to the principles of proportionality and necessity in data processing. Finally, an approach that involves publishing raw, unaggregated data from the monitoring system, even if labelled as anonymised, is also professionally unacceptable. Without robust anonymisation techniques and aggregation, there is a significant risk of re-identification, especially when combined with other publicly available information. This would constitute a serious breach of data protection legislation and ethical standards, potentially leading to severe consequences for individuals and damage to the reputation of the public health body. Professionals should employ a decision-making framework that begins with identifying the public health objective. This should be followed by a thorough assessment of available data and the legal and ethical constraints surrounding its use, particularly concerning data protection legislation like UK GDPR. The next step involves exploring various data handling and dissemination methods, prioritising those that maximise public benefit while minimising individual risk. Collaboration with legal and data protection experts is crucial throughout this process.

Scenario Analysis: This scenario presents a common challenge in public health surveillance: balancing the need for timely data to inform interventions with the ethical imperative to protect individual privacy and maintain public trust. The professional challenge lies in navigating the legal and ethical boundaries of data sharing, particularly when dealing with sensitive health information that could potentially identify individuals or stigmatise specific communities. The rapid dissemination of information is crucial for effective public health response, but it must be done responsibly and in accordance with established guidelines. Correct Approach Analysis: The best professional practice involves a multi-faceted approach that prioritises data anonymisation and aggregation before wider dissemination, coupled with clear communication about the purpose and limitations of the data. This approach aligns with the principles of data protection and ethical research, as enshrined in UK data protection legislation such as the Data Protection Act 2018 and the UK GDPR. Anonymisation and aggregation reduce the risk of re-identification, thereby safeguarding individual privacy. Furthermore, transparent communication about the surveillance system’s objectives and how data will be used fosters public trust and encourages continued cooperation. This method ensures that public health needs are met without compromising fundamental ethical obligations. Incorrect Approaches Analysis: Disseminating raw, identifiable case data without explicit consent or robust anonymisation measures is ethically and legally unacceptable. This approach violates the principles of data minimisation and purpose limitation under the UK GDPR, as it collects and shares more data than necessary for the stated public health purpose and potentially uses it for unintended secondary purposes. It also breaches the duty of confidentiality owed to individuals whose health data is collected. Sharing aggregated data that still allows for the potential identification of individuals within small or distinct populations, even if not explicitly named, is also problematic. While aggregation is a step towards anonymisation, if the resulting dataset can still be linked back to individuals through other means (e.g., unique combinations of characteristics in a small community), it fails to adequately protect privacy. This could lead to stigmatisation and discrimination, undermining public health efforts. Focusing solely on the speed of data dissemination without considering the ethical implications of data handling and privacy is a failure of professional responsibility. While speed is important in public health emergencies, it cannot override legal and ethical obligations. A rushed approach that neglects data protection can lead to significant reputational damage for public health bodies and erode public confidence, ultimately hindering future surveillance and intervention efforts. Professional Reasoning: Professionals should adopt a risk-based approach to data handling in surveillance. This involves: 1. Identifying the specific public health objective and the minimum data required to achieve it. 2. Implementing robust data anonymisation and aggregation techniques appropriate to the data type and population size. 3. Ensuring compliance with all relevant UK data protection legislation (e.g., Data Protection Act 2018, UK GDPR). 4. Developing clear protocols for data sharing, including consent mechanisms where appropriate and feasible. 5. Communicating transparently with the public about surveillance activities, data usage, and privacy safeguards. 6. Regularly reviewing and updating data handling practices to reflect evolving ethical standards and technological capabilities.

The evaluation methodology shows that a local authority is considering implementing a new public health intervention aimed at reducing childhood obesity. This scenario is professionally challenging because it requires balancing the potential benefits of the intervention with the ethical considerations of data collection, resource allocation, and community engagement, all within the framework of UK public health legislation and guidance. Careful judgment is required to ensure the intervention is both effective and ethically sound. The approach that represents best professional practice involves a comprehensive needs assessment informed by a review of existing evidence and local data, followed by a robust stakeholder engagement process to co-design the intervention. This is correct because it aligns with the principles of evidence-based practice and participatory public health, as advocated by bodies like the National Institute for Health and Care Excellence (NICE) and the Faculty of Public Health (FPH). Specifically, NICE guidance emphasizes the importance of understanding the local context and involving communities in decision-making to ensure interventions are relevant, acceptable, and sustainable. The FPH’s ethical guidelines also stress the need for public health professionals to act in the public interest, which includes ensuring interventions are based on sound evidence and are developed collaboratively with those they aim to serve. This approach maximizes the likelihood of successful implementation and positive health outcomes while respecting community autonomy and promoting equity. An approach that prioritizes rapid implementation based solely on national guidelines without local adaptation or community consultation is professionally unacceptable. This fails to acknowledge the unique socio-economic and cultural context of the local population, potentially leading to an intervention that is ineffective or even counterproductive. It also neglects the ethical imperative to involve the community in decisions that affect their health, undermining principles of empowerment and shared responsibility. An approach that focuses exclusively on the cost-effectiveness of the intervention, disregarding potential equity impacts or unintended consequences for specific population subgroups, is also professionally unacceptable. Public health policy in the UK is guided by principles of social justice and equity, as outlined in the Marmot Review and subsequent policy documents. Ignoring these aspects can exacerbate existing health inequalities. An approach that relies solely on anecdotal evidence and personal experience, without rigorous data collection or consideration of established evidence bases, is professionally unacceptable. Public health interventions must be grounded in robust evidence to ensure they are effective and safe, as mandated by professional standards and regulatory expectations for evidence-based practice. Professionals should employ a decision-making framework that begins with a thorough understanding of the problem and the local context. This involves a comprehensive needs assessment, drawing on both quantitative and qualitative data. Subsequently, evidence from existing research and best practice guidelines should be critically appraised. Crucially, engagement with all relevant stakeholders, including the target population, community groups, and other professionals, is essential to co-design and refine interventions. This iterative process ensures that interventions are evidence-informed, contextually appropriate, ethically sound, and likely to achieve their intended public health goals.

Scenario Analysis: This scenario is professionally challenging because it requires a public health professional to navigate the specific eligibility criteria for a postgraduate qualification while also managing the expectations of a colleague. Misinterpreting or misapplying the Faculty of Public Health (FPH) Part A examination requirements could lead to a colleague pursuing an inappropriate course of action, potentially wasting their time and resources, and damaging professional relationships. Careful judgment is required to provide accurate guidance that aligns with FPH regulations. Correct Approach Analysis: The best professional approach involves clearly and accurately communicating the FPH Part A examination eligibility requirements as outlined by the Faculty of Public Health. This means advising the colleague to consult the official FPH website, relevant guidance documents, or directly contact the FPH for definitive information regarding their specific qualifications and experience. This approach is correct because it adheres to the principle of providing accurate, evidence-based information derived from the authoritative source. It respects the regulatory framework established by the FPH and ensures the colleague receives guidance that is compliant with the examination’s prerequisites. This upholds professional integrity and avoids providing potentially misleading advice. Incorrect Approaches Analysis: Advising the colleague that their current postgraduate diploma in a related health field is “definitely sufficient” without verifying against the FPH’s specific criteria is professionally unacceptable. This is an assumption that bypasses the need for official confirmation and could lead to the colleague being deemed ineligible later, causing significant disappointment and wasted effort. It fails to acknowledge the precise nature of FPH eligibility, which often involves specific modules, duration of study, or professional experience beyond a general diploma. Suggesting that the colleague “should be fine” because other individuals with similar backgrounds have been accepted in the past is also professionally unsound. Past acceptance of other candidates does not set a precedent for future eligibility, as FPH regulations and their interpretation can evolve. Relying on anecdotal evidence rather than official guidance is a failure to adhere to the established regulatory framework and can lead to incorrect assumptions about eligibility. Recommending that the colleague “just apply and see what happens” disregards the importance of understanding and meeting eligibility criteria upfront. While an application might eventually be reviewed, this approach fails to provide proactive, informed guidance. It places the burden of determining eligibility entirely on the application process itself, rather than empowering the colleague with knowledge of the requirements beforehand, which is a core aspect of professional advice. Professional Reasoning: Professionals should adopt a decision-making process that prioritizes accuracy, adherence to regulatory frameworks, and evidence-based guidance. When faced with inquiries about professional qualifications or examinations, the first step should always be to identify the authoritative source of information for the specific requirement (in this case, the Faculty of Public Health). This involves consulting official documentation, websites, or directly contacting the relevant body. Professionals must then accurately interpret and communicate this information, avoiding assumptions, anecdotal evidence, or casual recommendations. The goal is to empower the inquirer with correct information to make informed decisions, thereby upholding professional standards and preventing potential negative outcomes.

Scenario Analysis: This scenario presents a professional challenge due to the potential for bias in data collection and interpretation, which can lead to flawed public health interventions and misallocation of resources. The need to accurately identify health inequalities requires rigorous methodological approaches that are both ethically sound and compliant with UK public health guidance. Careful judgment is required to select the most appropriate research method that minimises bias and maximises the validity of findings. Correct Approach Analysis: The best approach involves a mixed-methods study design, incorporating both quantitative data on health outcomes and qualitative data on lived experiences. This approach is correct because it aligns with the principles of robust epidemiological research and the ethical imperative to understand the multifaceted nature of health inequalities. Quantitative data, such as routinely collected health statistics and surveys, can identify patterns and prevalence of disease across different socioeconomic groups. However, to truly understand the drivers of these inequalities, qualitative methods like focus groups and in-depth interviews are essential. These methods allow for the exploration of barriers to accessing care, social determinants of health, and the subjective experiences of affected populations. This comprehensive understanding is crucial for developing targeted and effective public health interventions, as advocated by UK public health frameworks that emphasise evidence-based practice and addressing the social determinants of health. Incorrect Approaches Analysis: An approach relying solely on readily available aggregated national health statistics without further stratification or qualitative exploration is professionally unacceptable. This fails to account for the heterogeneity within national data and may obscure specific local or group-level inequalities, leading to interventions that are not tailored to the actual needs of vulnerable populations. It also risks perpetuating existing health disparities by overlooking the nuanced reasons behind them. An approach that prioritises rapid deployment of a single, unvalidated screening tool based on anecdotal evidence is also professionally unacceptable. This violates principles of evidence-based practice and research ethics. Without prior validation, the screening tool’s accuracy is unknown, potentially leading to misdiagnosis, unnecessary anxiety for individuals, and inefficient use of public health resources. It bypasses the necessary steps of rigorous research design and ethical approval. An approach that focuses exclusively on individual lifestyle choices as the primary explanation for observed health differences, while ignoring broader socioeconomic and environmental factors, is professionally unacceptable. This represents a victim-blaming perspective and fails to address the systemic issues that contribute to health inequalities, as outlined in UK public health policy which stresses the importance of social determinants. Such an approach would lead to ineffective and potentially stigmatising interventions. Professional Reasoning: Professionals should adopt a systematic approach to research design. This involves clearly defining the research question, considering the ethical implications of data collection and use, and selecting methodologies that are appropriate for the research question and context. A critical appraisal of existing literature and data is essential to identify gaps and potential biases. When investigating health inequalities, a commitment to understanding both the ‘what’ (prevalence and patterns) and the ‘why’ (underlying causes) is paramount, often necessitating a mixed-methods approach. Adherence to established research ethics guidelines and UK public health guidance on tackling inequalities should inform every stage of the research process.

Scenario Analysis: This scenario is professionally challenging because it requires balancing the need for efficient resource allocation and maintaining service quality with the ethical imperative of fairness and transparency in assessment processes. The Faculty’s reputation and the integrity of its examinations are at stake, necessitating a decision that upholds these principles. The pressure to address perceived inconsistencies while adhering to established policies demands careful judgment. Correct Approach Analysis: The best professional approach involves a thorough, evidence-based review of the examination blueprint and scoring methodology. This includes a detailed analysis of the blueprint’s alignment with learning outcomes, the scoring rubric’s consistency, and the statistical performance of individual questions. This approach is correct because it directly addresses the concerns raised by the faculty members by seeking objective data to validate or refute their perceptions. It aligns with the Faculty’s commitment to fair and valid assessment, as outlined in its examination regulations, which mandate that all assessments are rigorously developed and evaluated to ensure they accurately measure competence. This systematic review process is the most ethical and professional way to identify and rectify any genuine issues with the examination’s design or scoring. Incorrect Approaches Analysis: One incorrect approach would be to immediately revise the blueprint and scoring based solely on anecdotal feedback from a few faculty members without conducting a formal review. This is professionally unacceptable because it bypasses the established quality assurance mechanisms and risks making arbitrary changes that could introduce new biases or inaccuracies. It fails to uphold the principle of evidence-based decision-making, which is fundamental to maintaining the credibility of professional examinations. Another incorrect approach would be to dismiss the faculty members’ concerns outright without any investigation, citing the current blueprint and scoring as definitive. This is ethically problematic as it demonstrates a lack of responsiveness to legitimate professional feedback and could foster an environment of distrust. It neglects the Faculty’s responsibility to continuously improve its assessment processes and ensure they remain fit for purpose. A further incorrect approach would be to implement a blanket retake policy for all candidates who may have been affected by perceived inconsistencies, without first identifying the nature and extent of any actual issues. This is an inefficient and potentially unfair use of resources. It also undermines the validity of the examination for those who performed well based on the existing assessment criteria, and it does not address the root cause of the perceived problems. Professional Reasoning: Professionals should approach such situations by first acknowledging and validating the concerns raised. They should then initiate a structured, evidence-gathering process to understand the issue objectively. This involves consulting relevant policies, seeking data, and engaging in collaborative problem-solving with stakeholders. The decision-making framework should prioritize fairness, validity, reliability, and transparency in all assessment-related matters, ensuring that any actions taken are justifiable and aligned with the overarching goals of the professional body.

Scenario Analysis: This scenario is professionally challenging because it requires the candidate to balance the need for comprehensive preparation with the practical constraints of time and available resources. The pressure to perform well in a high-stakes examination like the UK Faculty of Public Health Part A, coupled with the vastness of the syllabus, can lead to anxiety and inefficient study strategies. Making informed decisions about resource selection and timeline management is crucial for success and reflects professional competence in self-directed learning and resourcefulness. Correct Approach Analysis: The best approach involves a structured, evidence-informed strategy that prioritizes core FPH syllabus areas and utilises recommended resources. This includes a systematic review of the FPH curriculum, engagement with official FPH guidance on examination preparation, and the use of reputable, FPH-endorsed study materials. A phased timeline, incorporating regular self-assessment and practice questions, allows for progressive learning and identification of knowledge gaps. This aligns with the professional expectation of candidates to approach their development systematically and to leverage authoritative guidance, ensuring preparation is both thorough and targeted. Incorrect Approaches Analysis: One incorrect approach involves relying solely on a broad range of general public health textbooks without specific reference to the FPH syllabus or recommended reading lists. This is inefficient as it may lead to spending time on topics not directly relevant to the examination, failing to address the specific nuances and emphasis of the FPH Part A. It also bypasses the professional responsibility to consult official guidance. Another incorrect approach is to defer preparation until the final weeks before the exam, focusing only on memorisation of past paper questions. This is professionally unsound as it neglects the development of deep understanding and critical application of public health principles, which is the aim of the examination. It also increases the risk of superficial learning and an inability to adapt to novel question formats. A further incorrect approach is to exclusively use unofficial or anecdotal study guides without verifying their alignment with the FPH curriculum or their accuracy. This risks learning outdated or incorrect information, which is a significant ethical and professional failing. It demonstrates a lack of due diligence in resource selection and a disregard for the integrity of the examination process. Professional Reasoning: Professionals preparing for high-stakes examinations should adopt a strategic, self-directed learning approach. This involves: 1) Thoroughly understanding the examination’s scope and objectives by consulting official syllabi and guidance. 2) Prioritising resources that are directly relevant and authoritative. 3) Developing a realistic and phased study plan that incorporates regular review and assessment. 4) Seeking feedback and adapting study methods based on performance. This systematic process ensures effective learning and demonstrates professional commitment to competence.

The investigation demonstrates a common challenge in public health: the need to balance the imperative of data-driven decision-making with the ethical and legal obligations surrounding data privacy and consent. Professionals are tasked with using available information to plan and evaluate programs effectively, but must do so within the strict confines of data protection regulations. This scenario requires careful judgment to ensure that the pursuit of public health goals does not inadvertently breach individual rights or legal requirements. The most appropriate approach involves a thorough review of the existing data governance framework and relevant legislation, specifically the UK Data Protection Act 2018 (which incorporates GDPR principles) and any relevant professional guidance from bodies like the Faculty of Public Health. This approach prioritizes understanding the legal basis for processing the data, ensuring that any use aligns with the original purpose for which consent was obtained or that a lawful basis for further processing exists. It also necessitates considering the ethical implications of data use, particularly regarding potential re-identification risks and the principle of proportionality. By consulting legal and ethical experts, and ensuring transparency with stakeholders, this method upholds both regulatory compliance and public trust. An approach that focuses solely on the potential public health benefits without adequately assessing the legal and ethical basis for data use is professionally unacceptable. This fails to acknowledge the fundamental right to privacy and the legal restrictions on processing personal data. It risks contravening the Data Protection Act 2018 by potentially using data beyond the scope of consent or without a legitimate lawful basis, leading to significant legal repercussions and damage to the reputation of the public health body. Another professionally unsound approach is to proceed with data analysis based on assumptions about public willingness to share data for research purposes. This disregards the explicit requirements for informed consent and the legal necessity of having a clear lawful basis for data processing. It overlooks the fact that public health initiatives, while beneficial, do not grant carte blanche to use personal data without adherence to data protection principles. Finally, an approach that prioritizes expediency by using anonymised data without verifying its true anonymisation status or considering the potential for re-identification is also problematic. While anonymisation is a key technique for data protection, if the process is flawed or the data is not sufficiently de-identified, it can still lead to breaches of privacy and non-compliance with data protection laws. The responsibility lies in ensuring robust anonymisation techniques are employed and validated. Professionals should adopt a systematic decision-making process that begins with identifying the specific data in question and the intended use. This should be followed by a comprehensive review of applicable legislation (e.g., Data Protection Act 2018) and professional ethical guidelines. Consultation with legal counsel and data protection officers is crucial. A risk assessment should be conducted to evaluate potential privacy impacts and re-identification risks. Finally, decisions should be documented, and transparency maintained with all relevant stakeholders.

This scenario presents a professional challenge due to the inherent tension between communicating complex public health risks to a diverse public and ensuring that communication is aligned with the interests and understanding of various stakeholder groups, including those with potentially conflicting agendas. Effective risk communication requires not only accuracy and clarity but also sensitivity to public perception, trust, and the potential for misinformation. Stakeholder alignment is crucial for successful public health interventions, as it fosters buy-in, facilitates cooperation, and mitigates resistance. The challenge lies in navigating these dynamics ethically and effectively within the UK regulatory framework. The best approach involves a proactive and inclusive strategy that prioritizes transparency, evidence-based communication, and genuine engagement with all relevant stakeholders. This means developing clear, accessible messaging about the risks and proposed interventions, supported by robust scientific evidence. Crucially, it requires actively seeking input from diverse stakeholder groups early in the process, understanding their concerns, and incorporating their feedback where appropriate. This fosters trust and builds consensus, aligning communication efforts with broader public health goals. This approach is supported by principles of good governance and public health ethics, which emphasize accountability, transparency, and public participation. The Health and Safety at Work etc. Act 1974, while broad, underpins the general duty of care to protect health and safety, which extends to effective communication about risks. Furthermore, the principles of the UK’s Public Sector Equality Duty require consideration of how communication strategies impact different groups. An approach that focuses solely on disseminating information without seeking stakeholder input is professionally unacceptable. This fails to acknowledge the importance of public trust and can lead to misinterpretations or outright rejection of public health messages. It neglects the ethical imperative to engage with the public as active participants in their own health and safety. Such a strategy risks alienating key groups and undermining the effectiveness of public health initiatives, potentially contravening the spirit of public engagement expected in public health practice. Another professionally unacceptable approach would be to tailor communication to appease specific powerful stakeholders, even if it means downplaying or distorting the scientific evidence of risk. This is ethically unsound and potentially illegal, as it compromises the integrity of public health advice. It violates the duty to provide accurate and unbiased information to the public and could lead to adverse health outcomes if risks are not adequately communicated. This approach undermines public confidence in health authorities and contravenes the principles of evidence-based practice. Finally, an approach that relies on technical jargon and complex scientific language, assuming the public will understand it, is also flawed. While accuracy is important, effective risk communication requires translating complex information into accessible terms for a lay audience. Failing to do so creates barriers to understanding and can lead to confusion and inaction, which is detrimental to public health. This approach neglects the fundamental principle of clear and effective communication, which is a cornerstone of public health practice. Professionals should employ a decision-making framework that begins with identifying all relevant stakeholders and understanding their perspectives. This should be followed by developing clear, evidence-based communication objectives. The core of the process involves co-designing communication strategies with stakeholders, ensuring messages are tailored to different audiences while maintaining scientific integrity. Continuous evaluation and adaptation of communication efforts based on feedback and evolving circumstances are also essential.
