Flexible modelling for requirements engineering

Many applications that are developed do not completely fulfil the requirements of their stakeholders. This can be a result of inadequate requirements elicitation and poorly defined requirements. Many solutions, including model-driven inspired ones, have been proposed to improve the elicitation of the requirements, though many of them are not yet widely used in practice as they require training of both the employees and the stakeholders. In this paper we propose the use of exible modelling for eliciting and capturing the requirements of applications to facilitate the production of correct products that deliver on the contract defined between clients and developers. We argue that the use of exible modelling can lower the entry barrier for use in the industry. The pro- posed method, called FlexRE, is applied to a scenario to demonstrate its capabilities and ways it can be extended.
