      <description>Title: MEMO Organisation Modelling Language (1): Focus on organisational structure
&lt;br/&gt;
&lt;br/&gt;Authors: Frank, Ulrich
&lt;br/&gt;
&lt;br/&gt;Abstract: Organisation models are at the core of enterprise model, since they represent key aspects of a company's action system. Within MEMO, the Organisation Modelling Language (OrgML) supports the construction of organisation models. They can be divided into two main abstractions: a static abstraction is focusing on the structure of an organisation that reflects the division of labour with respect to static responsibilities and a dynamic abstraction that is focusing on models of business processes. In this report, those concepts of the OrgML are presented that serve modelling static aspects of an organisation. They cover prevalent concepts used in organisational charts as well as concepts required for specifying temporal units of work, roles and committees. The description of these modelling concepts comprises three parts: A meta model serves to specify the abstract syntax and semantics. A language description includes an overview of all concepts and the corresponding notational elements (concrete syntax). Finally, the use of the concepts is illustrated through various examples.</description>

&lt;br/&gt;Abstract: An enterprise model comprises various abstractions of an enterprise that represent both information systems and the surrounding action systems. These different models are integrated in order to avoid redundant work and to contribute to a tight and consistent integration of action systems and information systems. For this purpose, the method MEMO (Multi-Perspective Enterprise Modelling) features a family of modelling languages, each of which is aimed at representing specific perspectives and aspects of an enterprise. Within the MEMO languages, the Organisation Modelling Language (MEMO OrgML) is of outstanding relevance. It allows for creating elaborate models of business process types (organisational dynamics) and of organisation structures. Therefore, it is a key instrument for analysing and (re-) designing a company's action system, i.e. its key patterns of division of labour and coordination with respect to organisational goals. This report is intended to prepare for a major revision of the MEMO OrgML. Therefore, its focus on terminological foundations and on the comprehensive analysis of requirements related to the design of organisation modelling languages. The analysis was guided by a method for developing domain-specific modelling languages. It suggests focussing on use scenarios to analyse and refine requirements. The analysis is differentiated into general requirements for DSML and general as well as specific requirements for organisation modelling languages. The results are presented in an extensive dictionary of almost 70 requirements on different levels of abstraction.</description>

&lt;br/&gt;Abstract: An enterprise model comprises various abstractions of an enterprise that represent both information systems and the surrounding action systems. These different models are integrated in order to avoid redundant work and to contribute to a tight and consistent integration of action systems and information systems. For this purpose, the method MEMO (Multi-Perspective Enterprise Modelling) features a family of modelling languages, each of which is aimed at representing specific perspectives and aspects of an enterprise. Within the MEMO languages, the Organisation Modelling Language (MEMO OrgML) is of outstanding relevance. Its specification is distributed on two reports. A previous report focussed on the specification of the organisation structure. This report presents the part of the language specification that allows for modelling business processes. It builds on a further previous report that presents the results of an extensive requirements analysis. The report starts with an analysis of basic concepts and a discussion of peculiarities related to the specification of a process modelling language. Subsequently, the language specification is presented. It comprises a meta model with supplementary constraints, detailed comments on core language concepts and a dictionary of the notational symbols in two variants. Finally, the use of the language is demonstrated with examples.</description>
