Engineering disciplines: Data, Electronics, Computer science, AI.

Ethical issues: Diversity, Bias, Privacy, Transparency.

Professional situations: Rigour, Informed consent, Misuse of data, Conflicts with leadership / management.

Educational level: Advanced. 

Educational aim: To encourage ethical motivation. Ethical motivation occurs when a person is moved by a moral judgement, or when a moral judgement is a spur to a course of action. 

 

Learning and teaching notes: 

This case involves an engineer hired to manage the development and installation of a facial recognition project at a building used by university students, businesses and the public. It incorporates a variety of components including law and policy, stakeholder and risk analysis, and both macro- and micro-ethical elements. This example is UK-based: however, the instructor can adapt the content to better fit the laws and regulations surrounding facial recognition technology in other countries, if this would be beneficial.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this study to AHEP outcomes specific to a programme under these themes, access AHEP4 here and navigate to pages 30-31 and 35-37.

This case is presented in three parts. If desired, a teacher can use Part one in isolation, but Part two (focusing on the wider ethical context of the case) and Part three (focusing on the potential actions the engineer could take)develop and complicate the concepts presented in Part one to provide for additional learning. The case study allows teachers the option to stop at multiple points for questions and / or activities as desired.

Summary: 

Metropolitan Technical University (MTU), based in the UK, has an urban campus and many of its buildings are located in the city centre. A new student housing development in this area will be shared by MTU, a local college, and medical residents doing short rotations at the local hospital. The building has a public café on the ground floor and a couple of classrooms used by the university. 

The housing development sits alongside a common route for parades and protests. In the wake of demonstrations by Extinction Rebellion and Black Lives Matter, students have raised concerns to the property manager about safety. Despite an existing system of CCTV cameras and swipe cards, the university decides to install an enhanced security system, built around facial recognition technology that would enable access to the building and cross-reference with crime databases. To comply with GDPR, building residents will be required to give explicit consent before the system is implemented. Visitors without a student ID (such as café customers) will be buzzed in, but their image will be captured and cross-referenced before entry. A side benefit of the system is that MTU’s department of Artificial Intelligence Research will help with the installation and maintenance, as well as studying how it works, in order to make improvements. 

 

Dilemma – Part one:

You are an engineer who has been hired by MTU to take charge of the facial recognition system installation project, including setting policies and getting the system operational. With your background in AI engineering, you are expected to act as a technical advisor to MTU and liaise with the Facilities, Security and Computing departments to ensure a smooth deployment. This is the first time you have worked on a project that involves image capture. So as part of your preparation for the project, you need to do some preliminary research as to what best practices, guidance, and regulations apply.

 

Optional STOP for questions and activities: 

1. Discussion: What are the legal issues relating to image capture? Images allow for the identification of living persons and are therefore considered as personal data under GDPR and the Data Protection Act (2018).

2. Discussion: Sharing data is a legally and ethically complex field. Is it appropriate to share images captured with the police? If not the police, then whose crime database will you use? Is it acceptable to share the data with the Artificial Intelligence Research group? Why, or why not?

3. Discussion: Under GDPR, individuals must normally consent to their personal data being processed. How should consent be handled in this case?

4. Discussion: Does the fact that the building will accommodate students from three different institutions (MTU, the local college, and the hospital) complicate these issues? Are regulations related to students’ captured images different than those related to public image capture?

5. Activity: Undertake a technical activity that relates to how facial recognition systems are engineered.

 

Dilemma – Part two:

The project has kicked off, and one of its deliverables is to establish the policies and safeguards that will govern the system. You convened a meeting of project stakeholders to determine what rules need to be built into the system’s software and presented a list of questions to help you make technical decisions. The questions you asked were:

What you had thought would be a quick meeting to agree basic principles turned out to be very lengthy and complex. You were surprised at the variety of perspectives and how heated the discussions became. The discussions raised some questions in your own mind as to the risks of the facial recognition system.

 

Optional STOP for questions and activities:

The following activities focus on macro-ethics. This seeks to understand the wider ethical contexts of projects like the facial recognition system.

1. Activity: Stakeholder mapping – Who are all the stakeholders and what might their positions and perspectives be? Is there a difference between the priorities of the different stakeholders?

2. Activity: There are many different values competing for priority here. Identify these values, discuss and debate how they should be weighed in the context of the project.

3. Activity: Risks can be understood as objective and / or subjective. Research the difference between these two types of risk, and identify which type(s) of risks exist related to the project.

4. Discussion: Which groups or individuals are potentially harmed by the technology and which potentially benefit? How should we go about setting priorities when there are competing harms and benefits?

5. Discussion: Does the technology used treat everyone from your stakeholders’ list equally? Should the needs of society as a whole outweigh the needs of the individual?

6. Activity: Make and defend an argument as to the appropriateness of installing and using the system.

7. Discussion: What responsibilities do engineers have in developing these technologies?

 

Dilemma – Part three:

A few days later, you were forwarded a screenshot of a social media post that heavily criticised the proposed facial recognition system. It was unclear where the post had originated, but it had clearly been shared and promoted among both students and the public raising concerns about privacy and transparency. Your boss believes this outcry endangers the project and has requested that you make a public statement on behalf of MTU, reaffirming its commitment to installing the system.

You share the concerns, but have been employed to complete the project. You understand that suggesting it should be abandoned, would most likely risk your job. What will you tell your boss? How will you prepare your public statement?

 

Optional STOP for questions and activities:

Micro-ethics concerns individuals and their responses to specific situations. The following steps are intended to help students develop their ability to practise moral analysis by considering the problem in a structured way and work towards possible solutions that they can analyse critically.

 1. Discussion: What are the problems here? 

2. Discussion: What are the possible courses of action you can take as an employee?

 Students can be prompted to consider what different approaches they might adopt, such as the following, but can also develop their own possible responses. 

3. Discussion: Which is the best approach and why? – Interrogate the pros and cons of each possible course of action including the ethical, practical, cost, local relationship and the reputational damage implications. Students should decide on their own preferred course of action and explain why the balance of pros and cons is preferable to other options. The students may wish to consider this from other perspectives, such as: 

4. Activity: Public Communication – Students can practise writing a press release, giving an interview, or making a public statement about the case and the decision that they make.

5. Activity: Reflection – Students can reflect on how this case study has enabled them to see the situation from different angles. Has it motivated them to understand the ethical concerns and to come to an acceptable conclusion.

Topic: Ethical entrepreneurship in engineering industries.

Engineering disciplines: Mechanical engineering, Electrical and electronic engineering, Chemical engineering.

Ethical issues: Justice, Corporate social responsibility, Accountability.

Professional situations: Company growth, Communication, Public health and safety.

Educational level: Beginner to advanced.

Educational aim: To encourage ethical motivation. Ethical motivation occurs when a person is moved by a moral judgement, or when a moral judgement is a spur to a course of action. 

 

Learning and teaching notes: 

This case involves the CEO of Hydrospector, a newly formed company that makes devices detecting water leaks. The CEO has been working hard to secure contracts for her new business and has a personal dilemma in structuring her business model. She must balance the need to accelerate growth by working with high revenue global corporations, with her desire to bring a positive impact to the communities with greatest need. By working with less wealthy local authorities, the company risks slower business growth.

This dilemma can be addressed from a micro-ethics point of view by analysing personal ethics, intrinsic motivations and moral values. It can also be analysed from a macro-ethics point of view, by considering: corporate responsibility in perpetuating inequity versus closing the inequality gap; and sustainability in terms of the local socioeconomic system.

There is also a clear cultural context in this case study that provides an opportunity to develop cultural awareness when addressing engineering problems. Through this lens, this case can be structured to emphasise the need to engage with local communities and stakeholders – such as a UK company choosing to engage with its local community first. Or it can be framed to emphasise global responsibility whereby the CEO of a UK company chooses to address water shortages in South Africa.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

The case study is presented in three parts. Part one introduces the case and discusses personal and corporate ethical dilemmas, with an emphasis on ethical awareness. Pre-reading may be needed on the environmental, social, and governance (ESG) mandate and / or corporate social responsibility (CSR). Part two expands on Part one to bring in the socio-political elements of corporate responsibility. For Part three, instructors or programme directors could incorporate this exercise in projects that involve product development, with students working through Part one and two as examples. This part aims to encourage ethical action on the part of students who are developing their own products, so that they can consider aspects of justice, responsibility, and sustainability in their engineering solutions. This case also allows teachers the option to stop at multiple points for questions and / or activities as desired.

Foreword and suggested pre-reading for Part one:

In the last few years, there have been calls for more corporate responsibility in environmental and socioeconomic ecosystems globally. For example:

 

Part one:

Maria is a young co-founder and technical lead (CTO) living in the UK looking at the business development of her newly-formed transnational company, Hydrospector, based in Johannesburg (Joburg), South Africa, where her co-founder/CEO is located. The company makes devices that detect water leaks and the small team has been working hard to secure contracts for their new business. Maria is an electrical and electronics engineer by training and was the lead inventor for this technology. She has proven her technology works in detecting leaks early and at low levels, lowering the risk of damage to infrastructure that impacts local communities. The technology will also save companies millions each year by detecting low-level water loss that currently remains undetected. Her company is now in a position where they need to find customers.

Targeting big corporations will mean her technology will get out much more quickly and be a huge economic benefit to surrounding industries and society. Maria comes from a lower socioeconomic background in Lancashire (UK) and her personal experience of the economic disparity between the different areas she has lived in, means she feels strongly about not wanting to perpetuate this norm. She feels that Hydrospector’s business growth model needs to have a more active approach in preventing the widening of the socioeconomic gap. In Joburg, where the company is based, there are stark differences in the affluence of neighbouring communities. Should she focus on working with poorly-funded local authorities to help ensure their product gets to the places most in need, rather than prioritise projects that will be more lucrative and accelerate the business more quickly?

 

Optional STOP for questions and activities: 

1. Discussion: Personal values – what personal values are causing the internal conflict for Maria? Does her own background make a difference to the issues at stake? If Maria was from an affluent area / background, how may this have affected her perspective?

2. Discussion: Professional values – what ethical principles and codes of conduct are applicable to this scenario?

3. Discussion: Wider impact – is focusing on profit alone morally inferior to prioritising ESG?

4. Activity: In a group, split into two sides with one side defending a profit-driven business and the other defending a non-profit driven business. Use Maria’s case in defending your position.

5. Activity: Technical integration – undertake a technical activity in the areas of mechanical, electrical and / or chemical engineering related water flow detection sensors.

 

Foreword and pre-reading for Part two:

It is useful to learn more about the context (geographical, political, social and cultural) of this case study in order to gain a deeper understanding of the nuances that each scenario brings. The following section outlines the local problems with water supply and misuse in South Africa compared to the UK. The links below are starting points to explore these challenges further and carry out research when working on projects as an engineer. They represent perspectives from news, government, and industry sources.

 

Part two:

The CEO and Operations Manager of Hydrospector is Maria’s friend and co-founder, Lucy, who grew up in Joburg. Like Maria, Lucy grew up experiencing the socioeconomic disparity in her area. Lucy’s passion for bringing benefits to disadvantaged communities makes their collaboration an ideal partnership. The company started trading in South Africa where there is a particular interest from Johannesburg Water, the main local water supply company. Water supply shortages in the region have badly affected the country in recent years. Hydrospector has successfully won a bid with a venture capitalist based in South Africa and has rolled out the sensors in Makers Valley, Joburg, a region that has developed economically in recent years. Soon after, the company also won a contract to install sensors in the Merseyside region of the UK in a trial project co-funded by the local council and United Utilities.

 

Scenario A – Environmental impact:

Hydrospector’s components are sourced in South Africa with both manufacturing and assembly carried out locally in Joburg. It has taken Lucy and her team a year to develop supply and manufacturing operations to run smoothly and economically. To ship to the UK would be a financially better deal for the company than to source and manufacture the product locally in the UK. However, the impact of the carbon footprint would not help their ESG goals. Lucy will have to decide whether to ship the product from South Africa or produce the product locally and therefore set up another operations team in the UK. Setting up in the UK will cost the company more due to component pricing, but would support the local economy. The company could potentially afford to set up UK operations, but this will impact heavily on their financial profit forecast in the first couple of years.

 

Optional STOP for questions and activities: 

1. Discussion: What should Lucy decide? What considerations does she need to make for supply chain management, when considering local customers compared to global ones?

2. Discussion: What could be the unintended consequences of her decision? Consider this question from the following points of view: environmental, economic and social – the public view.

 

Scenario B – Unintended outcomes:

After six months’ post-installation work in inner-city Bertrams, Makers Valley, Johannesburg Water has contacted Hydrospector about the illegal tapping of its pipes. They suspect water is being stolen from these settlements according to data from the installed sensors. Furthermore, engineers from Johannesburg Water carrying out maintenance work have found some of the sensors have been deliberately damaged, which they suspect has been done so that illegal tapping goes undetected. Johannesburg Water wants to prosecute those responsible and has contacted Lucy to provide all the data logged from the sensors and the time/date stamps to identify specific details about damage. Lucy, however, is aware of cases where funds intended to be used to improve infrastructure for low-income households such as electricity, water supply and sanitation, have sometimes been poorly managed and at worse embezzled so that the communities are left worse off, with ageing pipes and infrastructure. She realises that some illegal tapping may have been done in order to provide for these communities.

Several weeks after this discovery, United Utilities in Merseyside has been in touch about local individuals and companies illegally accessing water from hydrants that are found in street drains for their own usage. These companies have mobile trucks and so have been difficult to find and prosecute. United Utilities would like Hydrospector’s full co-operation in providing the logging data needed, as well as installing sensors at targeted locations where they suspect misuse is happening. Lucy’s research has found that 99% of leakages in the UK are not illegally sourced but rather are due to poor pipe networks. In fact, 20% of water supply loss in the UK is due to leaks and paid for by the customer (domestic users).

 

Optional STOP for questions and activities: 

1. Discussion: How should Hydrospector respond to the two requests? Should the response be the same or different? If the same, why? If different, what makes the two cases different?

2. Discussion: Should water supply companies ultimately be responsible for water leakages? If so, why are they charging domestic users for the 20% water loss? What are the environmental implications of this business decision?

3. Discussion: Maria and Lucy are also concerned that, if these cases were to be picked up by the media, there might be a reputational risk for the company and their ability to achieve their business vision and goals. The co-founders are worried about their product’s unintended consequences., They feel that it could be misused, potentially exacerbate socio-economic inequality further and go against the intended use of the product. Are they right to be concerned? Are they responsible for unintended outcomes?

4. Activity: What role should engineers have in shaping public policy? Often laws and regulations related to policy are dependent on technical knowledge, but some engineers believe it is not their role or responsibility to help shape policy. Debate this issue, or research the relationship between engineering and policy.

 

Scenario C – Public trust:

Hydrospector has been involved in a project where it surveyed and identified significant leakages and damage to the water supply system in one of the communities in Joburg. The company has been asked by the local authorities not to disclose this information to other parties, particularly media outlets, due to the security risks, including potential terrorism. However, this will affect the transparency of the project, which is publicly funded. In addition, reporting these findings could help resolve the problems found, for example, supply and construction companies may be willing to step up to help.

The company suspects that the local authorities are seeking to avoid a public outcry for the sake of impact scores on customer satisfaction. However, without public knowledge, change to improve the situation is likely to be slow.

 

Optional STOP for questions and activities: 

1. Discussion: Should the company keep the data unpublished or report the data? What ethical reasons can you identify for either choice?

2. Discussion: Should transparency be prioritised over public trust every time? Why or why not?

3. Activity: Debate the above questions by splitting up the students and having each group / individual represent the potential perspectives of United Utilities, Johannesburg Water and Maria / Lucy.

4. Discussion: What guidelines should companies be given for releasing publicly funded data and data misuse?

 

Foreword and pre-reading for Part three:

This exercise can be supported by technical and non-technical sessions such as business models, SWOT analysis, project management and risk.

 

Part three:

First, introduce Parts one and two of this case study to inform the exercise as part of a student project, such as a final year capstone.

Design a business growth model for an engineered product, identifying the potential socioeconomic impact, providing a viable profitable forecast and a life cycle sustainability assessment. Explore the ESG indicators and Raworth’s Doughnut of social and planetary boundaries as starting points.

 

Optional STOP for questions and activities: 

1. Discussion and activity: Is impact your main priority? What type of impact are you looking to gain for your business? Consider economic, personal, social and environmental impacts – such as research exercise.

2. Discussion: What risks and opportunities can be identified (SWOT) for the different growth models that could be used to achieve the impact you desire?

3. Activity: Create a business growth model and plan based on your critical research.

4. Activity: Draft a CSR plan for this business.

5. Activity: Speak to people in non-engineering fields that can review and help develop your model.
