\section{Motivation}

Product configuration supports sales processes in companies through the possibility to structure and update knowledge about a product. A product configurator guarantees only valid product configurations are sold by a sales person. Usually, configuration processes are only done by a single user \cite{felferningGroupBasedConfiguration2016, velasquez-guevaraMultiSPLOTSupportingMultiuser2018a}.
In complex group configuration processes the risk of a single user making a mistake increases \cite{felfernigGroupDecisionSupport2011}.
Example scenarios are software release planning, travel planning, and construction planning \cite{felfernigOpenConfiguration2014}. All of these scenarios are group based configuration processes which are called "collaborative configuration", "community configuration", or "group-based configuration" \cite{felferningGroupBasedConfiguration2016, felfernigOpenConfiguration2014,mendoncaCollaborativeProductConfiguration2008,felfernigKnowledgebasedConfigurationResearch2014}.

In a group based configuration processes a group of people collaboratively configures a product which results in a configuration that ideally includes all preferences of participants. Implementation of such processes build upon concepts for collaboration, decision-making and require additional functionality such as recommender systems for finding solutions and conflict resolution \cite{felfernigKnowledgebasedConfigurationResearch2014}.

%TODO: Research gap and previous work -> are there many existing methods?

Furthermore, groups often have hierarchies or split competences that need to be considered. Moreover, decision processes in groups are not always democratic and individual members can have different roles.

\section{Objectives}

It will be investigated which methods and tools exist and are suitable to aid in group based configuration processes to support decision-making in these contexts. Identified methods and tools will be used in a holistic and generic approach. The implementation will be done based on the basis on "CAS Configurator Merlin" of "CAS Software AG". The suitability to aid users in configuration processes with this approach will be evaluated based on realistic scenarios. In addition, possible limitations and improvement potential will be discussed.

\section{Forschungsfragen}

\begin{enumerate}
    \item Wie kann die Entscheidungsfindung von Gruppen im Konfigurationsprozess (durch Recommender-Systeme) unterstützt werden? (Leitfrage)
    \item Welche neuen Anforderungen an Konfigurationssysteme ergeben sich durch die kollaborative Entscheidungsfindung?
    \item Welchen Einfluss hat die Gruppenhierarchie oder -dynamik auf den Entscheidungsprozess in gruppenbasierten Konfigurationsszenarien?
\end{enumerate}

\section{Methodik}

Es wird „Design Science Research“ nach K. Peffers verwendet. Hierbei wird die Arbeit in sechs Aktivitäten unterteilt, nämlich: Problem Identifikation und Motivation, Zieldefinition für eine Lösung, Umsetzung, Demonstration, Evaluation und  Kommunikation \cite{peffersDesignScienceResearch2007}. Die Arbeit lässt sich Strukturell in mehrere Arbeitspakete aufteilen, wobei die Identifikation des Problems und relevanter Literatur an erster Stelle stehen. Im nächsten Schritt der Umsetzung wird mit Hilfe von weiterer Literatur eine Lösung des Problems erarbeitet. Am Ende steht die Evaluation und eine mögliche Verfeinerung der Problemstellung \cite{offermannOutlineDesignScience2009}.
