Abstract

[Context&Motivation] Personas are a technique used to guide developing products accommodating people diversity. They are archetypes reflecting common combinations of users’ characteristics, needs and goals. Persons can add a human-centred facet to requirements engineering practice which is often revolving around the concept of business roles. [Question/Problem] Goal modelling is an example of mainstream requirements engineering approach driven by business roles and their responsibilities and needs represented as goals. Personnel in the system are expected to act according to this prescriptive specification. Personnel diversity is often seen as a customization and design issue. [Principal idea/Results]. In this paper we propose to consider such diversity as a conditional context in requirements modelling and, as an approach, augment Contextual Goal Model (CGM) with personas as a new contextual dimension. Additionally, we propose an algorithm to analyse the achievability of CGM goals in the presence of the personas contexts variation. We evaluate our approach using a Mobile Personal Emergency Response System (MPERS) implemented as a prototype. [Contribution] Our persona-based modelling approach paves the way to augment requirements with a consideration of people diversity and enrich the business perspective with a more user-centred design facet.
