PurposeThis paper aims to present a case study of the application of a methodology that represents an innovative strategy that integrates researches on interaction design and business process management with practical implications. This methodology is devoted to aligning the needs of enterprise system users with business processes (BPs).Design/methodology/approachThis approach establishes an unbroken network of links between BPs, task models and abstract representations of user interfaces. Once the models are linked, it is possible to identify the impact that any change on these models may produce in other models. The main challenge is to organize the linked models according to the organizational context and manage those links with consistency in order to support improving process efficiency and user productivity. This approach has been applied in a large telecommunications organization during four months with its application in two different projects and validated with a cost‐benefit analysis.FindingsApplying this approach in large organizations has demonstrated that: every involved stakeholder is capable of understanding the whole approach in one working day; creating the models and linking them with the corresponding business process models takes around three men/day per core business process; and applying this approach brings up to 60 per cent of return on investment related to process improvement and user experience.Originality/valueThe main differentials of this methodology include using simple models; considering light actions; preserving the independence of technology; and adopting a human‐oriented approach assuring that every managed information impacts people and not only systems, thus enabling fast adaptation to the business dynamism.

In this paper we describe how the identification of usability tasks in the task model as an early consideration of usability in the process can directly influence the design of usable User Interfaces (UI). We intend to make system analysts and UI designers work and communicate better by sharing artifacts, thus providing a process that aims at the integration of professionals working with a productive process in order to develop UIs with usability.
