    It is our pleasure to welcome the reader to the proceedings of the First Inter-
national Workshop on Requirements Prioritization and Enactment, PrioRE’17
co-located with the 23rd International Working Conference on Requirements
Engineering: Foundation for Software Quality (REFSQ 20167) held in Essen,
Germany.
    First in its series, the PrioRE’17 aims to play a role in bringing research ex-
perts and practitioners together, and provide them with a platform to exchange
their visions on requirements prioritization, release planning and their enact-
ment. The main focus will be on how requirements can be best prioritized, and
how the releases are planned and enacted.
    The Requirements Engineering process starts with requirements elicitation
and gathering, and ends with their enactment – i.e., the planning of their ac-
tual implementation and release. While the requirements elicitation phase is
strongly user-oriented, as it aims at capturing the user needs and preferences,
requirements enactment implies a decision making activity done by the software
development company, with the purpose of finding a proper implementation
scheduling on the basis of the company’s resource availability and other con-
straints. For this reason, practitioners are continuously challenged by the need
to afford costs – money, time, human resources, etc – that limit their capability to
deliver the implementation of new, user-requested requirements. This cost-value
trade-off weighs substantially on the success or failure of software projects, and
businesses in general. In order to tackle this problem and minimize the associated
risk of failure, careful but fast decision making activities have to be put in place,
to (i) prioritize the requirements, determining the order in which requirements
are implemented in an incremental development cycle; and (ii) properly enact
them into a concrete and resource-affordable development plan.
    The selection of papers was based on the reviews of an international program
committee. Each paper has received at least three reviews from program commit-
tee members and organisers. The reviews evaluated the maturity of manuscripts,
their scope with regard to the workshop goals, and the soundness of the presented
ideas. Based on the reviews, five papers were accepted for presentation at the
workshop. Two papers were accepted as a full paper, and three were accepted
as short papers. We, the organisers, thank the program committee members for
their effort:

 – David Ameller, Universitat Politcnica de Catalunya
 – Paolo Busetta, Delta Informatica
 – Maya Daneva, University of Twente
 – Carles Farr, Universitat Politcnica de Catalunya
 – Jesus Gorronogoitia Cruz, ATOS
 – Emitza Guzman, University of Zurich
 – He Jiang Dalian, University of Technology
 – Fitsum Kifetew, Fondazione Bruno Kessler
 – Emmanuel Letier, University College London
 – Rita Suzana Maciel, Federal University of Bahia
 – Patrick Mder, TU Ilmenau
 – Mirko Morandini, Wrth Phoenix
 – Denisse Munante, Fondazione Bruno Kessler

   All of the members of the program committee provided very useful hints to
the authors and submitted their reviews in time. Our special thanks go to all of
them.
