User Acceptance and the Socio-technical Approach Lecture 9 - 9. 2 Scope and Coverage This topic will cover: • Factors in user acceptance of technology • Human-computer interaction (HCI) • Socio-technical approach to implementing technology V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 3 Learning Outcomes By the end of this topic students will be able to: • Appreciate factors that influence user acceptance of IS • Understand the contribution of HCI principles to IS • Plan IS introductions with attention to human needs V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 4 Contents • User acceptance and the Technology Adoption Model • HCI principles in the design of IS interactions • Work design with socio-technical principles • User experience and IS design • Emphasis – People and Technology V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 5 Stakeholders • People, groups and organisations with an interest in an IS • . . . who have the power to affect the outcome and success of the system. • Identify: - V 1. 0 Who they are The level of their commitment Their power – to help or hinder Their interests Their requirements © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 8 Users as Stakeholders • Remember, the future users of an IS are people, not an organisation (have you ever actually spoken to a ‘University’) • Only animate beings and pre-programmed machines can do anything in the accepted sense of the word V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 9 IS Acceptance • Most IS depend, to a small or a large extent for their effectiveness, on willing and competent users • User Acceptance of the technology is key • IS effect will therefore depend on how people in an organisation engage with the technology • TWO main issues - Technology Acceptance - Human Computer Interaction (HCI) V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 12 Technology Acceptance UTAUT • Model has been extensively developed • Unified Theory of Acceptance and Use of Technology • In the developed model, Behavioural Intention (to use) is influenced by: - Performance Expectancy - Effort Expectancy - Social Influence • And Use Behaviour is influenced by: - Facilitation Conditions V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 13 UTAUT • Gender, Age, Experience and Voluntariness of use are other influencing factors • Reference is: - Venkatesh, V. , Morris, M. G. , Davis, G. B. , and Davis, F. D.

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 14 Use and HCI principles • When IS are designed, HCI principles can be employed to ensure ease of use – thus influencing one of the key aspects of user acceptance • Most famously Nielsen developed a set of heuristic principles to follow when designing an interface to a computer system • These (and more) are documented at the following URL: - http: //www. useit. com/papers/heuristic_list. html V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 15 Nielsen Heuristics • Heuristic Principles are, that interface designs should aim for: - Visibility of system status-The system should always keep users informed about what is going on, through appropriate feedback within reasonable time - Match between systems and real world-The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms - User control and freedom- Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Support undo and redo. - Consistency and standards- Users should not have to wonder whether different words, situations, or actions mean the same thing - Error prevention - Even better than good error messages is a careful design which prevents a problem from occurring in the first place.

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 16 - Recognition rather than recall - Minimize the user's memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another - Flexibility and efficient use - Accelerators -- unseen by the novice user -- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. - Aesthetic and minimalist design - Dialogues should not contain information which is irrelevant or rarely needed - Help users recognise, diagnose and recover from errors - Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution. - Help and documentation - Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation.

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 19 Sociotechnical Design of IS • The Socio-technical design movement, started many years ago, stresses the importance of Human ‘systems’ working in collaboration with Technological systems –both needing to be ‘designed’ to ensure success of the whole • For IS, this translates most frequently in the importance of actively involving human users in the process of the design of systems • A useful URL is: - http: //en. wikipedia. org/wiki/Sociotechnical_systems V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 20 Work design and IS design Work Design Principle Possible design use with IS Combine tasks Use IS to combine several processes into a single task Give a team responsibility for a significant part of the task. IS provides information to (whole) team Form natural work-groups Establish customer relations Vertical loading Open feedback channels Use IS to provide the team with better information about their customers IS takes over routine tasks and team are given more responsibility Use IS to pass on positive information from customers Based on, Table 8. 1. , Boddy, Boonstra and Kennedy (2008), page 222.

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 21 User Experience Design • Situation and Context of use • Environmental factors (noise, light, dirty environment) • Time factors (how much time, time versus accuracy) • Can information be retrieved from somewhere else (e. g. Address finders using post-code/zip code) • Frequency of use (e. g. If infrequent, is it simple – for example an automated ticketing machine? ) V 1. 0 © NCC Education Limited

User Acceptance and the Socio-technical Approach Lecture 9 - 9. 22 User Experience Design - Example • Designing the User Experience is concerned with the total context and use of an IS • The following URL gives a good example related to web marketing: • http: //www. hceye. org/Usability.
