Fifth International Workshop on Requirements Engineering:
Foundation for Software Quality

June 14-18 1999
Heidelberg, Germany
(preceding the CAiSE*99 conference)

The workshop programme and the workshop preparation kit will become available here.


Achieving high quality means to realise the needs of users and customers. These needs are elicited, negotiated, documented and validated during requirements engineering (RE). RE is therefore the most crucial phase of software development. The goals of RE are:

Conventional RE methods usually support only parts of this process or help stating only specific kinds of requirements.


The goal of the REFSQ workshop series is to improve the understanding of the relations between requirements engineering and software quality. More precisely, REFSQ aims at having intensive discussion provoked by brief presentations about:

At the REFSQ'94, '95, '97 and '98 workshops - all arranged in connection with earlier CAiSE-conferences - researchers and practitioners from various disciplines presented approaches to improve the definition and implementation of quality requirements. The success of the earlier REFSQ's has encouraged us to provide a follow-up workshop - REFSQ'99 - as a stage for the discussion of quality-related problems in RE as they have developed over the last year. In particular, we like to encourage people from the requirements engineering, software engineering and information systems fields to present their approaches to higher software quality and to discuss how requirements engineering can contribute to it.


In accordance with the special theme for CAiSE*99 - Component-Based Approaches - and following-up on issues raised at last year's workshop, REFSQ'99 specifically invites submissions addressing RE for Commercial Off-The-Shelf (COTS) systems. The emergence of COTS has divided traditional RE-processes into supplier-side and customer-side RE, with the two sides connected by the COTS-market. On the supplier side, RE has become integrated with marketing in order to satisfy and anticipate customer requirements which must be integrated with existing requirements, prioritised, bundled and scheduled for realisation in several versions and releases of the COTS-product, all in the presence of firm deadlines. On the customer-side, RE becomes increasingly concerned with the selection of available COTS products based upon a broad range of criteria, including aspects such as tailorability, implementation costs and conformance with legacy systems.

Relevant topics include, but are not limited to: classification of COTS requirements into domain-specific and standard ones, analysing the impact of requirements changes, support for change management, prioritising requirements for COTS, bundling requirements into COTS releases, configuration management for requirements, consideration of existing systems, and procurement of COTS.

REFSQ'99 also invites contributions from research and industry within other broad themes, such as:

  1. Embedding RE in the organisational context.
    Relevant topics include: smoothly extending existing methods, developing techniques that are specific for individual domains and applications, assessing the helpfulness of formal representations, change management, organisational learning, business processes, etc.

  2. Managing the quality of RE processes.
    Relevant topics include: resource estimation, establishing and using traceability, process modelling and monitoring, RE project organisation, quality models of RE and the RE process, environments for supporting RE processes, CAME environments, etc.

  3. Quality assurance and RE.
    Relevant topics include: models for quality assurance, considering quality assurance in RE, software quality and RE, specification of software quality requirements, measuring the quality of requirements, etc.

Note that the themes and the lists of topics for each theme are not intended to be exhaustive.


Papers of three types can be submitted to the workshop:

W O R K S H O P   F O R M A T

The workshop will be an interactive forum. Attendance will be limited to 30 people and all participants must have a paper accepted for the workshop. The workshop language is English.

The workshop will be organized in conjunction with the CAiSE*99 conference, and some earlier CAiSE conferences have required workshop participants to also attend the main conference.

The accepted papers will be made available electronically to all workshop participants before the workshop, so that presentations can be kept short. Each full-paper presentation will be summarized and commented on by all the other authors of full papers in the same session, acting as discussants. The discussants will be followed by a plenary discussion of the paper. In addition, there will be a plenary discussion at the end of each session.

At the end of the workshop there will be a general discussion, possibly including a brainstorming session about areas or topics of RE research that the participants perceive as important.

Send your full paper (max. 6000 words), position paper (max. 2000 words) or industrial problem statement (approx. 1 page) by e-mail or via normal post before March 15th (arrival date) to:

Email submission is encouraged, as the accepted papers will later be distributed to the other participants electronically.

Papers will be published in the REFSQ'99 workshop proceedings, and the papers will be made available electronically for the participants before the workshop. We also intend to provide paper preprints at the beginning of the workshop, but this is dependent on the funding we receive.
