Staff motivation leads to more efficiency, quality and enjoyment while performing tasks and fulfilling business requirements. Software-based motivation is the use of technology, such as gamification, persuasive technology and entertainment computing to facilitate and boost such behaviour and attitude. Despite its importance and unique peculiarities, motivation is not yet seen as a first class concept in enterprise modelling and requirements engineering literature. An ad-hoc design and deployment of software-based motivation might be detrimental and menace significantly other functional and non-functional requirements of the business, e.g., giving certain requirements more priority, increasing pressure to complete tasks, increasing competition to win the reward, etc. In this research, we follow a mixed method approach to conceptualise software-based motivation within enterprises taking the perspective of managers and employees and, also, experts from a wide range of domains including psychology, HCI, human factors in computing and software engineering. Our findings suggest the need for a personalised and human-centred engineering method of software-based motivation within enterprises which treats their profiles and preferences as equally important to their business roles. A blueprint of such method is introduced.
