A health informatics model for user-centred design using a positive deviance approach: a case for diabetes self-management
(University of the Western Cape, 2020) Petersen, Fazlyn
Over the past twenty years there have been substantive efforts across the African continent to ensure penetration and reach of mobile technology to the citizenry. However there continues to be a debate on precisely how developmental outcomes may be forged through this escalating penetration of communications technologies. This paper responds to the question of how development outcomes in the area of health, and specifically that of diabetes mellitus, can be achieved through the effective application of ICTs in the context of mobile applications. Diabetes Mellitus is a leading cause of morbidity in low-income and middle-income countries, with the number of patients projected to increase globally to 205 million by 2035. The increased number of patients in countries with limited resources requires innovative approaches to support a regime of patient self-management. In pursuance of this, and given the increasing pervasiveness of communications infrastructure amongst communities in South Africa, the role of Information and communications technology (ICT) in addressing the problem requires investigation. In particular, issues in relation to the adoption and effective use of ICTs, especially amongst previously disadvantaged and underserved communities, warrants exploration. The paper thus assesses the role of m-health at primary care level and posits a user-centred design approach to involve patients in designing an m-health intervention which meets their needs.

Barriers for user acceptance of Mobile Health applications for Diabetic patients: Applying the UTAUT model
(Springer Nature, 2020) Petersen, Fazlyn; Jacobs, Mariam; Pather, Shaun
The literature illustrates that technology will widen health disparity if its use is restricted to patients who are already motivated and demonstrate good self-management behaviours. Additionally, despite the availability of free mobile health (m-health) applications for diabetes self-management, usage is low. There are also limited studies of m-health acceptance in South Africa. This research is delineated to the Western Cape, South Africa. The populace suffers from increasing numbers of diabetic patients. Segments of the population also suffer from technological forms of exclusion, such as limited internet access. Therefore, the objective of this study was to identify challenges for user acceptance that discourages the use of m-health applications. This study analysed 130 semi-structured interviews, using thematic content analysis
Challenges for the adoption of ICT for diabetes selfmanagement in South Africa
(University of the Western Cape, 2019) Petersen, Fazlyn; Afeefa, Brown; Shaun, Pather; Tucker, William D
The increasing disease burden in developing countries inhibits the provision of quality care to citizens. However, the increased availability of information communication and technology (ICT) tools makes this a viable option for inclusion in primary health care. Even so, barriers are impeding the successful adoption and usage of ICT tools in health care contexts. This research focuses on one such context to identify the challenges and barriers for the adoption of ICT tools for diabetes self‐management in the Western Cape province of South Africa. The extended technology acceptance model (TAM) and four factors (educational, technological, economic, and sociocultural factors) were identified as a basis for investigation. Evidence was gathered from a sample of 131 diabetic patients using semistructured interviews. These factors, together with TAM constructs, explore how patients interact with ICT and their attitudes towards the use of ICT for diabetes self‐management. The results indicate that all four factors form barriers to ICT adoption for diabetes self‐management. These findings provide a basis to inform how future interventions at the primary health care level may be developed to overcome the identified barriers in efforts to integrate ICT tools into diabetic patients' daily selfmanagement routines.
Determinants for the acceptance and use of mobile health applications: Diabetic patients in the Western Cape, South Africa
(University of Western Cape, 2019) Petersen, Fazlyn; Pather, Shaun; Tucker, William D.
The increased pervasiveness of information communication and technology and increasing internet access creates anticipation for how contemporary technologies can address critical developmental problems. Non-communicable diseases are the leading cause of death globally, even though more than 40% of the deaths are premature and avoidable. Diabetes is such a disease that causes 80% of non-communicable disease deaths in low and middle-income countries. Diabetes is also the leading cause of death in the Western Cape province of South Africa. Diabetes thus constitutes a challenge to achieve Sustainable Development Goal 3 that focuses on health and well-being for all people, at all ages. The potential of technology, such as the use of m-health applications, is recognised as a means to advance the Sustainable Development Goals through supporting health systems in all countries.

Factors affecting consumer acceptance and use of mobile delivery applications in South Africa
(AOSIS, 2023) Musakwa, Isabel S.; Petersen, Fazlyn
During the 2020 global coronavirus (COVID-19) outbreak, mobile delivery applications flourished, facilitating consumer access to groceries. Research has shown, however, that usage remains low in developing countries such as South Africa. This research identifies factors that affect the acceptance and use of a mobile delivery application. It provides recommendations for application designers to improve application functionality and usability and for retailers to better understand customer needs.
Factors affecting the intention to use and use of mobile delivery applications in South Africa
(University of Western Cape, 2021) Musakwa, Isabel Sarurai; Petersen, Fazlyn
During the global 2020 COVID-19 outbreak, mobile delivery service applications became prevalent as they facilitated consumer access to groceries. Research has shown increased use of mobile delivery service applications in developed countries. This contrasts with research in developing countries, like South Africa, where usage is still low. Previous research has failed to address why consumers in developing countries use mobile delivery service applications at a lower rate. Hence, this case study investigated customer experiences using a South African retailer mobile delivery service application. The Unified Theory of Acceptance and Use 2 (UTAUT2) was used as a theoretical basis.
Impact of culture on the adoption of diabetes self-management applications: Cape flats, South Africa
(ifip, 2021) Petersen, Fazlyn
Diabetes is a global health problem with a high mortality rate. The research indicates low levels of technology use amongst diabetic patients in low socioeconomic environments and minority groups. We posit that the culture of patients is a potential reason for the low adoption and use of technology. However, research on the proliferation of culture at an individual level is limited. Therefore, this paper assessed the influence of culture on mobile application adoption and use amongst diabetic patients in the Cape Flats, South Africa. This study used key constructs from the Theory of Planned Behaviour (TPB) and Hofstede’s cultural dimensions. It was analysed using survey data from 439 respondents using purposive sampling. It was found that the dimensions of Hofstede and the Theory of Planned Behaviour can identify how culture influences mobile application adoption of diabetic patients in the geographical Cape Flats area. However, this research indicates a stronger relationship between culture and diabetes self-management activities than culture and the adoption of mobile applications.
Impact of Socio-Demographic Factors on the Acceptance of Information Communication and Technology (ICT) for Diabetes Self-care
(Springer Nature Switzerland, 2020) Tucker, William D; Baker, Adiel; Petersen, Fazlyn; Pather, Shaun
This research investigates the impact of socio-demographic factors such as age, gender, income and location on ICT acceptance for diabetes selfcare. The investigation is due to the increasing number of diabetic patients in South Africa, where large segments of the population experience technological forms of exclusions. The context warrants research in geographical areas where ICT use is not pervasive yet. This research, used the UTAUT model with purposive sampling for 497 diabetic respondents, residing in low socio-economic communities. It analysed survey data using linear regression. It found that age had a strong moderating effect on all four UTAUT constructs. Gender only had a moderating effect on performance expectancy and social influence. In contrast to findings in the extant literature, income and location had no significant moderating effect in this context.
The realisation of business benefits when implementing mandatory software in an IT department: a case study in a South African financial services organisation
(University of the Western Cape, 2011) Petersen, Fazlyn; Mitrovic, Zoran; Dept. of Information Systems
No organisation has an endless and unlimited supply of money, especially in a recessive economy, and therefore decisions have to be made as to which areas an organisation will invest in. As organisations, such as YZ1 financial services organisation, are focused on seeing returns on investment (ROI), implementing software that is not being used will not render any benefits to the organisation. Research problem: Project Managers (PMs) in YZ organisation’s IT department need to perform mandated processes, as defined in their centralised repository. PMs need to use Financial and Planning Software (FPS)2 software to perform certain project management activities, as required by their job function. However, it was found that MPP3 software, another tool, was used for more detailed project schedules, as well as activities that were not strictly enforced by management, the Project Office or the Quality Assurance team. Therefore, from this discovery, it was not clear whether the intended benefit of implementing this mandatory software (FPS) was being realised – since implementing software that is not being utilised fully would not deliver the intended benefits to the IT department (Devaraj & Kohli 2003), even if the software is termed ‘mandatory’. Objective: The primary objective of this research was to explore and optimise the key success factors for an effective implementation of mandatory software in a department, in order to derive the intended business benefits. Literature Review: Literature was reviewed in the search for models or theories that explore the relationship between the use of mandatory software and the achievement of business benefits. The Information Management Body of Knowledge (IMBOK) was selected as this framework defines the relationship between IT and the realisation of business benefits, and ultimately the achievement of any business strategy. The literature review focused predominantly on the level of user involvement, change management, as well as factors that influence the usage of mandatory software by individuals. 1. The name of the organisation utilised has been changed. Refer to Ethical Consideration 2. The name of the tools utilised has been changed. Refer to Ethical Consideration and list of acronyms 3. The name of the tools utilised has been changed. Refer to Ethical Consideration and list of acronyms. Focus was given to organisational factors affecting usage, such as top management support and organisational processes. A model was compiled using unique constructs in the Technology Acceptance Model (and TAM2), the Motivational Model (MM) and the Model of PC Utilisation (MPCU) – in order to test user acceptance of mandatory software. The literature study concludes with a review of an approach to benefits management including five stages, namely: identifying and structuring benefits, planning for the realisation of benefits, executing the plan, in addition to the evaluation and the review. Research design and methodology: A case study was used in this research, as it examined the phenomenon in its natural setting, employing multiple methods of data collection to gather information from a few entities (groups and data sources). In this way, it was not limited to only qualitative or quantitative approaches, but utilised mixed methods instead. A mixed methods approach was used in order to elaborate, enhance and clarify the results from the qualitative research through the results of the quantitative analysis. Findings: The main finding, based on the compilation of three models of user acceptance, proved that FPS was not being utilised as intended. There was also no evidence of an improvement in business operations. Therefore, benefits management was negatively impacted. Organisational processes were dentified as the most important organisational factor, influencing the usage of FPS software. Own technological capability was considered to be the least important factor, as respondents believed that they had sufficient IT skills in order to learn how to use FPS software. Change management was rated negatively; and as a result, it impacted the usage of FPS, as users were not involved in the decision to implement, and had limited interaction in the implementation process. In addition, there was no evidence found that benefits management was conducted in the IT department; and therefore, the impact of using alternative software could not be quantitatively assessed. Recommendations: In concluding this research, it is recommended that the “best practice”, derived from the pertinent literate should be followed more diligently if YZ organisation is to benefit from the implementation of mandatory software. For example, in this research, it was found that top management’s support of FPS (second most important organisational factor influencing use) was lacking, despite the literature suggestion that senior management involvement in changing technology is crucial for organisational commitment. It is suggested that a more formal approach to benefits management should be implemented. It is also recommended that further study should be conducted – in order to explore the applicability of the Japanese framing (achieving benefits from IT software through the concept of strategic instinct, rather than strategic alignment) in the context of a developing country (such as South Africa).
The role of culture in the adoption of mobile applications for the self‑management of diabetes in low resourced urban communities
(Springer, 2022) Jacobs‑Basadien, Mariam; Pather, Shaun; Petersen, Fazlyn
Diabetes mellitus has been documented as a global health problem with a high mortality rate. In the current digital age, the use of technology to overcome such health problems in pursuance of Sustainable Development Goal 3 is widely recognised. The increased penetration of mobile devices provides one avenue to support the self-management of conditions such as diabetes. As a first step towards this, individuals have to first accept and use the technology. However, the literature indicates low levels of technology use amongst diabetic patients with low socio-economic indicators. We posit that the culture of patients is a contributory factor for the low acceptance and use of technology. This study assessed how culture influences mobile health (m-health) acceptance among diabetic patients from low-resourced urban communities through semi-structured interviews. The theoretical model that was used as a lens for the investigation comprised a juxtaposition of Hofstede's cultural dimensions and the Unified-Theory of Acceptance and Use of Technology 2 (UTAUT2).
Students’ engagement in an anonymous peer review: Using the open-source sakai platform
(ifip, 2021) Petersen, Fazlyn; Groenewald, Bradley
There is a need to provide quality education without discrimination or prejudice to all students. However, there are challenges in implementing quality education in large classes, especially during remote learning. Literature indicates that providing lecturer feedback can become a tedious task, especially in large classes. Literature states that involving students in the peer review process can improve the quality of their submissions. This research used a case study and thematic analysis. Qualitative data were collected from 179 third-year Information Systems students who used the Opensource Sakai Platform. Students reviewed another student’s report, without knowing their identity. The research used self-determination theory as a theoretical basis. The achievement of perceived autonomy is supported as an anonymous peer review helped students to empower themselves. Perceived competence was also achieved as the anonymous peer review improved the quality of work submitted and the development of workplace skills.
Towards a model for user-centred design using a positive deviance approach: A case for diabetes self-management

Towards student inclusivity during COVID-19: Testing the #datafree Moya messenger
(CSALL University of Durban-Westville, 2020) Petersen, Fazlyn
The coronavirus has highlighted the socio-economic plights of many of our students who are not able to continue learning due to the lack of internet access and the high cost of data. As a result, a large majority of students may be excluded when our learning management systems are not zero-rated. On 15 April 2020, not all Network Providers have zero-rated the University of the Western Cape’s iKamva e-learning management system. This has resulted in the need to implement innovative options. This exploratory case study piloted the #datafree Moya Messenger application which should allow 500 students access to instant messages without having data. The pilot performed ten tests to test the usability and accessibility of the application. Nine of the ten tests were achieved. Findings indicated challenges in the initial implementation of the application to the class and the need to have mobile data or WiFi turned on for use. Despite the intention to keep all students connected, the application was not available to iPhone users, so it was not entirely inclusionary. However, it may still be a more inclusive option than using e-learning systems that are not zero-rated.
